Description

  The present invention relates to a toilet cleaning device that detects a user of a toilet using a human body detection sensor and performs automatic cleaning after use, and further includes a remote control that can perform toilet cleaning even by a user operation. It is invention regarding.

2. Description of the Related Art A toilet cleaning device that includes a system that electrically controls toilet cleaning, detects a user leaving the toilet using a human body detection sensor, etc., and performs toilet cleaning automatically is widely known.
Such a toilet bowl cleaning apparatus may be provided with a remote control that can be operated by the user, and the user can consciously clean the toilet bowl at an arbitrary timing by operating the remote control.
This remote control preferably uses a battery as a driving power source in order to simplify the construction at the time of installation and to be able to freely select the installation location.
In addition, the remote controller needs to transmit user operation information and the like to the main body side that controls toilet cleaning, and uses a wireless signal such as infrared rays or radio waves as its transmission means.

  When such a remote controller is used, most of the driving power of the remote controller is used for detecting an operation input and transmitting a signal to the main body. For this reason, in order to make the battery life of the remote controller as long as possible, that is, the time for battery replacement, it is necessary to reduce the power consumption in driving these remote controllers.

Reducing the power consumption of a remote controller is a conventionally known problem, and many low-power consumption driving technologies using a single remote controller have been disclosed.
For example, in a remote control equipped with an infrared-type hand-hold sensor for detecting operation input, the frequency of use is learned, and when the frequency of use is low, sensing is performed at a slower cycle than when the frequency of use is high, thereby reducing the frequency. It is possible to drive power consumption.
Also, in view of the fact that there is no need to send a new cleaning request by remote control operation to the main body side of the toilet bowl cleaning device while performing toilet cleaning by a request from the remote controller, by stopping sensing during the toilet bowl cleaning, There is also means for low power consumption drive.

  Furthermore, in the technique described in Patent Document 1, the main body side of the toilet bowl cleaning device is provided with charging means that can attach and detach the remote control, and charging the remote control battery from the main body of the toilet bowl cleaning device prevents the battery capacity from being depleted. It is out.

JP-A-9-84144

However, the low power consumption driving technique as described above cannot provide a sufficient effect when the remote controller is used frequently.
Moreover, even if sensing is stopped during toilet flushing, most of the day is a time zone during which toilet flushing is not performed, and it is not possible to expect a long battery life in actual use.
Furthermore, since the remote control is basically installed at a position where the user can easily reach and reach the user's eyes, if the remote control is installed, the user will inevitably want to operate the remote control to clean the toilet. Become.
In such a case, after the user leaves the toilet bowl, the automatic detection by the human body detection sensor is performed, but the user does not wait for the user to operate the remote controller to perform the toilet cleaning. Therefore, the number of times the remote control is used inevitably increases, and the remote control battery is consumed significantly.

  On the other hand, in the configuration of Patent Document 1, a mechanism for charging the remote control battery is required on the main body side of the toilet bowl cleaning device, which increases costs. Furthermore, since the remote control can be attached and detached, there is a problem that it is not suitable for installation in a public toilet space where theft or mischief occurs.

  The present invention has been made to solve the above-described problems. The problem of the present invention is that the remote control operation is suppressed to an appropriate frequency of use without adding special parts or mechanisms, thereby extending the battery of the remote control. An object of the present invention is to provide a toilet cleaning device that can have a long service life.

In order to achieve the above object, according to the first aspect of the present invention, a toilet cleaning means for driving an electromagnetic valve for supplying cleaning water to the toilet and a user who transmits a propagation wave and based on its reflection level. A human body detecting means for detecting the presence or absence of a radio wave, a receiving means for transmitting a wireless signal based on a user's operation, receiving a wireless signal from a remote controller powered by a battery, and the human body detecting means being undetected from the detection state In a toilet flushing apparatus comprising a main body control unit that starts toilet flushing by the toilet flushing means when the first predetermined time has elapsed or when the receiving means receives the wireless signal, The main body control unit is configured to change the setting so that the first predetermined time is shortened when the receiving unit receives the wireless signal.
Accordingly, the remote control operation can be suppressed to an appropriate frequency of use without adding special parts or mechanisms, and the battery life of the remote control can be extended.

According to a second aspect of the present invention, the remote controller includes a battery voltage measurement unit that measures a voltage value of a battery that is a power source, and the transmission unit transmits the information on the voltage value, and The main body control unit changes the setting so that the first predetermined time is shortened when the voltage value received by the receiving unit is less than a predetermined voltage value.
As a result, when the battery level is sufficient, the user can have time to select whether to clean the toilet bowl by remote control or to clean the toilet bowl based on the human body detection status. While maintaining good, the battery life of the remote control is not significantly impaired.

According to a third aspect of the present invention, the main body control unit until the second predetermined time longer than the first predetermined time elapses after the receiving unit receives the information of the operation detecting unit. In this period, the setting is changed so that the first predetermined time is shortened.
As a result, until the remote control is operated, the user can have time to choose whether to clean the toilet bowl by remote control or to clean the toilet based on the human body detection status. Although it can be maintained, the battery life of the remote control is not significantly impaired.

According to a fourth aspect of the present invention, the main body control unit learns the usage frequency of each time zone of the toilet, and the first predetermined time is shortened in a time zone where the usage frequency is a certain value or more. The setting is changed so as to become.
This allows the battery life of the remote control to be extended by preferentially executing toilet cleaning based on the human body detection status when the usage frequency is high, and when the usage frequency is low, the user can perform toilet cleaning by remote control operation. Since it is possible to delay the time for selecting whether to perform cleaning or toilet cleaning based on the human body detection status, it is possible to maintain a good balance between the user's convenience and the extension of the battery life of the remote controller.

  ADVANTAGE OF THE INVENTION According to this invention, the toilet cleaning apparatus which can prolong the lifetime of the battery of a remote control can be provided by suppressing remote control operation to an appropriate use frequency, without adding a special component or mechanism.

(First embodiment)
First, a first embodiment of the present invention will be described.
FIG. 1 is a schematic view illustrating a toilet bowl cleaning device according to the first embodiment of the invention.
FIG. 2 is a block diagram illustrating the toilet bowl cleaning device according to the first embodiment.

The toilet cleaning device 100 according to the present embodiment includes a toilet 600, a water passage 700 that supplies cleaning water to the toilet 600, a main body case 190 provided so as to cover a part of the water passage 700, and a main body case 190. A main body control unit 200 having a solenoid valve 400 that supplies and stops washing water to and from the toilet 600, and a toilet cleaning means 260 that controls opening and closing operations of the solenoid valve 400, and a main body case 190 And a light emitting / receiving unit 300 attached thereto.
The main body control unit 200 can be configured by a microprocessor, a memory, a program for operating these, and the like (not shown above), and controls the operation of the toilet bowl cleaning device 100.

In addition, the main body control unit 200 includes a human body detection unit 240 for determining whether a person is sitting on the toilet bowl 600 or not. The light projecting element 320 of the light projecting / receiving unit 300 transmits infrared light as a propagation wave, and the light is reflected by the back of the user seated on the toilet 600, and the light receiving element 340 receives the reflected light. The human body detection means 240 compares the reflection level received by the light receiving element 340 of the light projecting / receiving unit 300 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 that, it is determined that there is no object, and the detection result is output as an electric signal to the toilet cleaning means 260 through the wiring.
The toilet flushing means 260 controls the driving of the electromagnetic valve 400 according to the detection result received from the human body detection means 240, and supplies flush water from the water supply source 500 to the toilet 600 through the water passage 700.

In addition, the main body control unit 200 includes a receiving unit 220 that receives a radio signal from a remote controller 800 provided on the wall. The receiving means 220 outputs the result of receiving the radio signal as an electric signal to the toilet cleaning means 260 through the wiring.
The toilet flushing means 260 controls the drive of the electromagnetic valve 400 based on the reception result received from the receiving means 220, and supplies flush water to the toilet bowl 600 from the water supply source 500 through the water passage 700.

FIG. 3 is a block diagram illustrating the remote controller according to the first embodiment.
The remote controller 800 according to this embodiment includes a switch 980 that is operated by the user to wash the toilet bowl, an operation detection unit 940 that detects an operation on the switch 980, and a result detected by the operation detection unit 940. A transmission unit 920 that transmits a radio signal to the reception unit 220 included in the toilet cleaning device 100, and a battery 960 that is a driving power source of the remote controller 800.
The operation detection unit 940 and the transmission unit 920 are provided in the remote control unit 900. The remote control unit 900 can be configured by a microprocessor, a memory, a program for operating these, and the like (not shown above). The operation of the remote controller 800 is controlled.
As the switch 980, for example, a push button type switch or a proximity switch capable of non-contact operation by an infrared method is used. However, the installation position and method of the switch 980 are not limited to this, and may be changed as appropriate.

Hereinafter, a specific cleaning operation of the present embodiment will be described with reference to the drawings.
FIG. 4 is a time chart illustrating the operation of the toilet bowl cleaning device when the remote control is not installed in the first embodiment.
In the time chart shown in FIG. 4, the driving cycle of the human body detection unit 240 and the human body detection signal, the toilet cleaning determination of the main body control unit 200, the radio signal to the reception unit 220, and the driving of the toilet cleaning unit 260 are shown.

In FIG. 4, the human body detection means 240 repeats the detection operation intermittently in the drive cycle F1. This F1 is, for example, a period of 2 seconds. When the user sits on the toilet bowl 600, the human body detection signal of the human body detection means 240 exceeds the detection threshold value and is detected (time t1). When a predetermined time T0 has elapsed since the detection of the human body detection means 240, the main body control unit 200 determines toilet flushing (time t2). This T0 is set to 6 seconds, for example. Thereafter, when the user ends excretion and leaves, the human body detection signal of the human body detection means 240 falls below the detection threshold value and is not detected (time t3). When a predetermined time T1 has elapsed since the human body detection means 240 was not detected due to the user's sitting, the toilet bowl cleaning means 260 opens the electromagnetic valve 400 and starts cleaning the toilet bowl 600 (time t7). . This T1 is set to 10 seconds, for example.
In FIG. 4, the cleaning operation is performed when the remote controller 800 is not installed, and the receiving unit 220 does not receive a radio signal. Although details will be described later with reference to FIG. 7, when the remote controller 800 is installed, the control is changed to shorten the predetermined time T1.

  As described above, when the human body detecting means 240 detects the user from the non-detected state and the predetermined time T1 elapses, the toilet cleaning is started. In the following description, this cleaning is called automatic cleaning. The satisfaction condition for executing the automatic cleaning described in FIG. 4 is referred to as a first condition.

FIG. 5 is a time chart illustrating the operation of the toilet bowl cleaning device when the remote control is installed in the first embodiment.
Each item of the time chart shown in FIG. 5 and various operations up to time t2 are the same as the contents described in FIG. Differences from the embodiment of FIG. 4 will be described below.
When the user is seated, when the user operates the switch 980 of the remote controller 800, a radio signal is transmitted from the transmission means 920 of the remote controller 800. When the receiving means 220 receives this radio signal, the toilet bowl cleaning means 260 opens the electromagnetic valve 400 and starts cleaning the toilet bowl 600 (time t4). In this case, the cleaning operation is not performed even if the predetermined time T1 elapses after the user leaves the seat. That is, when a cleaning operation is performed by operating the remote controller 800, the automatic cleaning due to the first condition determined by the human body detection unit 240 is canceled (time t7). The time chart of FIG. 5 shows the case where the user operates the remote controller 800 while sitting, but the same applies when the remote controller 800 is operated while sitting.

  As described above, toilet cleaning is started by a radio signal transmitted by a user's remote control operation. In the following description, this cleaning is referred to as intention cleaning, and is established for executing the intention cleaning described in FIG. The condition is called the second condition.

Here, the data content of the radio signal transmitted by the transmission unit 920 will be described.
FIG. 6 is a schematic view illustrating the data format of the radio signal according to the first embodiment.
The radio signal data includes a start code, an ID code, a cleaning code, a battery voltage value state, and an end code.
The start code is a code indicating that data starts from here, and is preferably a fixed value.

The ID code is a value stored in the main body control unit 200 and the remote control unit 900 individually. The main body control unit 200 performs control according to the received radio signal only when the ID code included in the received radio signal matches the stored value. This is because when a plurality of toilet bowl cleaning devices 100 and remote controllers 800 are connected, a pair of remote controllers 800 are distinguished from each other so that operations of remote controllers that are not paired are not accepted.
The cleaning code is a code indicating the type of cleaning. Based on this value, the main body control unit 200 determines whether to switch the cleaning time or perform cleaning itself. Of course, the setting of the cleaning time is not limited to a plurality, and only one type may be set, or a code for instructing to perform cleaning may be transmitted.

The battery voltage value state is a code representing the battery voltage of the battery 960. This may be a value obtained by A / D converting the voltage value of the battery 960, or 1-bit information indicating whether or not the battery voltage is in a lowered state. A specific method of utilizing the battery voltage value state will be described in a second embodiment described later.
The end code is a code indicating that the data ends here, and may be a fixed value or a value related to the four codes described above. For example, if the total value of four codes or a value that becomes a fixed value by adding to the total value of four codes is used, the reliability of data is improved.

FIG. 7 is a time chart illustrating the operation of the toilet bowl cleaning device when the remote control is installed in the first embodiment.
Although FIG. 6 is a time chart for intention cleaning by remote control operation, FIG. 7 is a time chart for automatic cleaning by the human body detection means 240.
In the time chart shown in FIG. 7, the items in the time chart described in FIG. 4 and the processing at the same time are the same as described above, and thus the description thereof is omitted. Differences from the embodiment of FIG. 4 will be described below.

The main body control unit 200 receives a radio signal from the remote controller 800 before time t1 when the user is seated (time t9). The radio signal to be received may be the same as the data format described in FIG. Here, it is only necessary for main body control unit 200 to be able to recognize that remote controller 800 with the same ID code exists in the same space, and the setting contents of the cleaning code and the battery voltage value state may be arbitrary. As for the transmission timing, the remote controller 800 may periodically transmit, or a signal generated by a previous user's remote control operation may be used. At this time, the main body control unit 200 recognizes that the remote controller 800 is installed.
After that, the human body detecting means 240 detects the human body and is not detected (from time t1 to time t3).
When a predetermined time T11 elapses after the human body detection means 240 is not detected due to the user's sitting, the first condition for starting automatic cleaning is established, and the toilet cleaning means 260 sets the electromagnetic valve 400 to The opening of the toilet 600 is started to start cleaning (time t17). However, T11 is shorter than the predetermined time T1 described in FIG. 4, and is set to 4 seconds, for example.

As described above, in the time chart of FIG. 7, the timing for establishing the first condition for starting the automatic cleaning is earlier than in the case of the time chart of FIG. 4.
As for the cleaning operation after leaving the seat, basically toilet cleaning by automatic cleaning as described in FIG. 4 may be performed, and intention cleaning by remote control operation is not necessary. In addition, when intention washing is performed by remote control operation while sitting, it can be determined that necessary toilet cleaning has been performed at the operation timing, and thus automatic cleaning after sitting is not necessary as described with reference to FIG.
However, if the remote controller 800 is installed, the user after sitting away does not wait for the automatic cleaning, and the consciousness to perform intention cleaning by the remote controller 800 is activated, and the number of times the intention cleaning is performed. It will increase.
Therefore, as described with reference to FIG. 7, when the main body control unit 200 determines that the remote controller 800 is installed, the automatic cleaning is preferentially performed by increasing the timing of starting the automatic cleaning after leaving the seat. The control is changed so that it can be executed. Here, as a specific means for speeding up the timing, the predetermined time for establishing the first condition is shortened from T1 (10 seconds) to T11 (4 seconds).

Here, in order to make the following description easy to understand, the operation modes of the main body control unit 200 in FIGS. 4 and 7 are distinguished and called as follows.
As shown in FIG. 4, when the remote controller 800 is not installed, the main body control unit 200 has a relatively long time for establishing the first condition for starting automatic cleaning, and this operation mode is referred to as a normal cleaning mode. Call.
On the other hand, when the remote controller 800 is installed as shown in FIG. 7, the main body control unit 200 sets the first condition for starting the automatic cleaning at a relatively short time, and this operation mode is changed to the early cleaning. This is called a mode.

FIG. 8 is a flowchart showing the operation of the toilet bowl cleaning apparatus according to the first embodiment.
The flow of operation mode switching according to the installation state of the remote controller 800 is summarized as a flowchart as shown in FIG. The flow of FIG. 8 will be described below.
First, it is determined whether a radio signal from the remote controller 800 has been received in the past (S100). This may be a determination as to whether a wireless signal has been received even once in the past, or a determination as to whether it has been received a plurality of times. If no radio signal has been received (No in S100), the remote control 800 is not installed, so the normal cleaning mode is set (S101). If a radio signal has been received (Yes in S100), the remote control 800 is installed, so the early cleaning mode is set (S102).

Thus, the operation mode of the main body control unit 200 is switched between when the remote controller 800 is installed and when it is not installed. Specifically, when the remote controller 800 is installed, the operation mode is set so that the first condition for starting the automatic cleaning is advanced and the automatic cleaning is started before the user performs the remote control operation. Has been switched. By doing so, the frequency with which the user operates the remote control after leaving the seat is reduced.
Accordingly, the remote control operation can be suppressed to an appropriate frequency of use without adding special parts or mechanisms, and the battery life of the remote control can be extended.

(Second Embodiment)
From here, the second embodiment will be described.
Since the basic configuration and control contents of the toilet bowl cleaning device 100 and the remote controller 800 according to the second embodiment may be the same as those described in the first embodiment, the description thereof is omitted.
The difference from the first embodiment is that the remote controller 800 includes means for measuring the battery voltage of the battery 960 and the main body control unit based on the content of the battery voltage value state code in the data format of the radio signal. Reference numeral 200 denotes a point where the operation mode is switched, and the contents thereof will be described below.

FIG. 9 is a block diagram illustrating a remote control according to the second embodiment.
The difference from FIG. 3 described in the first embodiment is that the remote controller 900 includes a battery voltage measuring unit 970. The remote controller 900 can measure the voltage of the battery 960 by the battery voltage measuring means 970, and can transmit the measured result as a battery voltage value state code. The data content to be transmitted may be a multi-bit value obtained by A / D conversion, or only 1-bit information indicating whether or not the battery voltage is lowered.

FIG. 10 is a flowchart showing the operation of the toilet bowl cleaning apparatus according to the second embodiment.
The flow of operation mode switching of the main body control unit 200 according to the battery voltage value of the remote controller 800 is summarized as a flowchart as shown in FIG. The flow of FIG. 10 will be described.
Steps having the same processing contents as those in FIG. 8 described in the first embodiment are given the same step numbers.

  First, it is determined whether a radio signal from the remote controller 800 has been received in the past (S100). This may be a determination as to whether a wireless signal has been received even once in the past, or a determination as to whether it has been received a plurality of times. If no wireless signal has been received (No in S100), it is determined that the remote controller 800 is not installed, and the normal cleaning mode is set (S101). If a radio signal has been received (Yes in S100), it is determined whether a radio signal has been received from the remote controller 800 at the current timing (S200). If no radio signal is received (No in S200), no particular processing is performed and the operation mode is maintained at the current setting. If the wireless signal is received (Yes in S200), the battery voltage value state code is determined in the received signal (S201).

  At this time, if the battery voltage value status code is an A / D value of the battery voltage, a comparison with a predetermined voltage is sufficient, and if it is 1-bit information indicating whether or not the battery voltage is lowered, the data can be determined. If the battery voltage is not lowered as a result of the determination of the battery voltage value state code (No in S201), the battery is sufficiently charged and the normal cleaning mode is set (S101). If the battery voltage has dropped (Yes in S201), the early cleaning mode is set as the remaining battery level is low (S102).

This embodiment is different from the first embodiment in that not only the remote controller 800 is installed but also the early cleaning mode is set only when the battery 960 of the remote controller 800 is low. Is a point.
In other words, when the remaining battery level is low, the battery should be replaced as soon as possible. However, there are cases where it is not possible to expect the same day replacement in a public space such as a public facility. Therefore, only when the remaining battery level is low, the timing for establishing the first condition for temporarily starting the automatic cleaning is advanced to reduce the number of remote control operations.

  As a result, when the remaining battery level is sufficient, the user can postpone the time to select whether to clean the toilet bowl by remote control operation or to perform automatic cleaning based on the human body detection status. However, the battery life of the remote controller is not significantly impaired.

(Third embodiment)
From here, the third embodiment will be described.
Since the basic configuration and control contents of the toilet bowl cleaning device 100 and the remote controller 800 according to the third embodiment may be the same as those described in the first embodiment, the description thereof is omitted.
The difference from the first embodiment is that the operation mode switching is executed only under a certain condition by partially changing the control content of the main body control unit 200, and the content will be described below. .

FIG. 11 is a flowchart showing the operation of the toilet bowl cleaning apparatus according to the third embodiment.
Steps having the same processing contents as those in FIG. 8 described in the first embodiment and FIG. 10 described in the second embodiment are denoted by the same step numbers.
First, it is determined whether a radio signal from the remote controller 800 has been received in the past (S100). This may be a determination as to whether a wireless signal has been received even once in the past, or a determination as to whether it has been received a plurality of times. If no wireless signal has been received (No in S100), it is determined that the remote controller 800 is not installed, and the normal cleaning mode is set (S101). If a radio signal has been received (Yes in S100), it is determined whether a radio signal has been received from the remote controller 800 at the current timing (S200).

  If no wireless signal is received (No in S200), the process proceeds to the next process (S301). If a wireless signal is received (Yes in S200), a timer is set (S300). Here, a timer for measuring a certain period (for example, 5 minutes) is started. It also sets a count value for timing 5 minutes. Note that this timer determines that 5 minutes have elapsed when the count value reaches 0 in the countdown method. Subsequently, the count value of the timer is determined (S301). At this time, if the count value of the timer is 0 (Yes in S301), it means that 5 minutes have elapsed since the user operated the remote controller, so the normal cleaning mode is set (S101). When the count value of the timer is not 0 (No in S301), it means that 5 minutes have not passed yet, so the early cleaning mode is set (S102).

This embodiment is different from the first embodiment in that not only the remote controller 800 is installed, but also the early cleaning mode is set for a certain period of time after the remote controller 800 is operated. .
In other words, when the user operates the remote control, the user will continue to be more aware of the remote control operation, and the user can try to perform intention cleaning by using the remote control without waiting for the start of automatic cleaning after separation. Increases nature. Therefore, only when a remote control operation has been performed previously, the timing of establishment of the first condition for temporarily starting automatic cleaning is advanced to suppress the number of remote control operations.

  As a result, until the remote control operation is performed, the user can have time to select whether to clean the toilet bowl by the remote control operation or to perform automatic cleaning based on the human body detection status. However, the battery life of the remote controller is not significantly impaired.

(Fourth embodiment)
From here, the fourth embodiment will be described.
Since the basic configuration and control contents of the toilet bowl cleaning device 100 and the remote controller 800 according to the fourth embodiment may be the same as those described in the first embodiment, the description thereof is omitted.
The difference from the first embodiment is that the operation mode switching is executed only under a certain condition by partially changing the control content of the main body control unit 200, and the content will be described below. .

Specifically, the control content is changed based on the use frequency of the toilet 600, and first, learning of the use frequency will be described.
The main body control unit 200 divides a day into a predetermined number of time frames, stores the number of times the toilet bowl 600 is used in each time frame, and calculates the use frequency.
FIG. 12 is a schematic view illustrating a use frequency table according to the fourth embodiment.
In this example, one day is divided into 32 time frames. That is, each time frame is 45 minutes. Then, in each time frame, the number of times the toilet 600 is used is integrated. As the number of times the toilet 600 is used, the number of times that automatic cleaning based on the first condition or intention cleaning based on the second condition is executed can be used.
For example, in the time frame 1, the number of uses is 0, and in the time frame 6, the number of uses is 7.

The history of the number of times of use is overwritten every day, and information on the latest usage frequency is always stored. If it does in this way, according to the frequency | count of use of each time frame, it can classify | categorize into a time frame with a high usage frequency, and a low time frame with a fixed value as a boundary.
For example, if the fixed value is 5, if the number of uses is 5 or more, it is determined that the time frame is used frequently, and if it is less than 5 times, it is determined that the use frequency is low.

FIG. 13: is a flowchart which shows operation | movement of the toilet bowl washing | cleaning apparatus concerning 4th Embodiment.
The flow of operation mode switching according to the frequency of use is summarized as a flowchart as shown in FIG. The flow of FIG. 13 will be described below.
Steps having the same processing contents as those in FIG. 8 described in the first embodiment are given the same step numbers.

  First, it is determined whether a radio signal from the remote controller 800 has been received in the past (S100). This may be a determination as to whether a wireless signal has been received even once in the past, or a determination as to whether it has been received a plurality of times. If no wireless signal has been received (No in S100), it is determined that the remote controller 800 is not installed, and the normal cleaning mode is set (S101). If a wireless signal has been received (Yes in S100), the number of times of use of the current time frame is determined (S400). As a result of the determination, if the number of uses is 5 times or more (Yes in S400), the early cleaning mode is set (S102). If it is less than 5 times (No in S400), the normal cleaning mode is set (S101).

This embodiment is different from the first embodiment in that not only the remote controller 800 is installed, but also the early cleaning mode is set only for a time frame in which the toilet 600 is used frequently.
As a result, in the time frame with high usage frequency, the automatic cleaning by the human body detection means 240 is more preferentially executed than the intention cleaning by the remote control operation, and the number of remote control operations is reduced.

  As a result, when the usage frequency is high, the battery life of the remote controller 800 can be extended by preferentially executing automatic cleaning based on the human body detection status. When the usage frequency is low, the user can perform toilet cleaning by remote control operation. Since it is possible to delay the time for selecting whether to perform intention cleaning or automatic cleaning based on the human body detection status, it is possible to maintain a good balance between the user's convenience and the life of the battery of the remote controller 800.

(Fifth embodiment)
From here, the fifth embodiment will be described.
As described with reference to FIGS. 4 and 7 of the first embodiment, when the remote controller 800 is installed, the predetermined time T1 (T11) for satisfying the first condition is shortened to satisfy the first condition. The timing is advanced.
However, if the intention cleaning by the remote control operation is performed immediately after the user leaves the seat, the remote control operation is performed before the first condition for automatic cleaning is satisfied, and the frequency of use of the remote control 800 Cannot be suppressed properly.
More specifically, in the first embodiment, the predetermined time T11 when the remote controller 800 is installed is 4 seconds after the user has left the seat, but the user operates the remote controller within 4 seconds. It is.

In order to avoid this, 4 seconds set as the predetermined time T11 may be further shortened, but this time cannot be shorter than the driving cycle F1 (2 seconds) of the human body detection means 240. This is because the human body detection means 240 can update the detection status of the user only at the timing of the driving cycle F1.
Therefore, in the fifth embodiment, the timing for establishing the first condition is made earlier by changing the driving cycle F1.

FIG. 14 is a time chart illustrating the operation of the toilet bowl cleaning device when the remote control is installed in the fifth embodiment.
In the time chart shown in FIG. 14, each item of the time chart explained in FIG. 7 in the first embodiment and the processing at the same time are the same as described above, and the explanation is omitted. Differences from the embodiment of FIG. 7 will be described below.
The main body control unit 200 recognizes the presence of the remote controller 800 by receiving a radio signal from the remote controller 800 at time t9.
Thereafter, the seating of the user is detected at the timing of time t1, but at this time, the driving cycle of the human body detection means 240 is changed to F2, which is a period shorter than F1. The period of F2 can be set to 1 second, for example.

Thereafter, the user leaves the seat at time t3, the first condition is satisfied at time t27, and automatic cleaning is started. Thereafter, the driving cycle of the human body detection means 240 returns to F1 (2 seconds).
That is, the driving cycle of the human body detection means 240 is accelerated only during the period when the user's seating is detected. By doing so, the timing of establishment of the first condition can be advanced.
In the first embodiment, the timing at which the first condition is satisfied cannot be made shorter than the driving cycle F1 of the human body detection means 240, but in the fifth embodiment, F2 having a shorter driving cycle than F1 is used. As a result, the timing at which the first condition is satisfied can be further advanced. In the present embodiment, the driving cycle of F2 is 1 second, but it is also possible to make the cycle shorter, so that the number of remote control operations after leaving the seat can be further reduced.

Although it is possible to set the driving cycle to the cycle F2 uniformly regardless of the detection state of the human body, the power consumption of the main body control unit 200 increases steadily.
When the toilet bowl cleaning device 100 is a battery-driven type or a type equipped with a hydroelectric power generation mechanism that uses cleaning water, the toilet bowl cleaning device 100 itself must be driven with low power consumption. It is not desirable for power consumption to constantly increase.
Therefore, as in the present embodiment, if the driving cycle of the human body detection means 240 is accelerated only during human body detection, the frequency of use of the remote controller 800 can be appropriately suppressed while minimizing the power consumption of the toilet bowl cleaning device 100. The battery 960 of the remote controller 800 can have a long life.

The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. As long as the features of the present invention are provided, those skilled in the art appropriately modified the design of the above-described embodiments are also included in the scope of the present invention.
For example, the installation forms such as the shapes, dimensions, materials, and arrangements of the elements included in the toilet bowl cleaning device 100 and the remote controller 800 are not limited to those illustrated, and can be changed as appropriate.

Moreover, each element with which each embodiment mentioned above is provided can be combined as long as technically possible, and the combination of these is also included in the scope of the present invention as long as it includes the features of the present invention.
For example, control combining the third embodiment and the fourth embodiment can be easily invented from the features of the present invention.
