Description

  The present invention relates to a cleaning apparatus main body installed in a toilet and a hot water cleaning apparatus that includes a remote controller that transmits an operation signal to remotely operate the cleaning apparatus main body, and injects cleaning water into a human body part for cleaning.

  In a hot water cleaning device that sprays cleaning water on a human body part and cleans it, a cleaning device is usually installed separately from the cleaning device main body installed in the toilet bowl, and the user operates the remote control. In general, the main body is operated to perform cleaning and other operations.

By the way, in public toilets, a plurality of booths are provided side by side in the toilet, and a toilet and a hot water washing device are installed for each booth.
In the conventional hot water cleaning device, the operation signal from the remote control is generally transmitted to the cleaning device body side as an infrared signal. In this case, since infrared light cannot pass through the booth wall, the signal from the remote control in a booth is It is usually difficult for a cleaning device main body in another booth to be received.

  However, in the case of the communication method using infrared rays, not only the infrared rays emitted from the remote control but also the reflected light from the booth wall enters the receiving portion of the washing device main body, so the washing device main body side depends on the wall material and color There is a problem in that the reception state of the mobile phone changes, and the reliability of communication is not sufficient.

Therefore, it is conceivable that communication between the remote controller and the cleaning apparatus main body is communication using radio waves.
In this case, the influence of the material and color of the booth wall can be eliminated, and the directivity is not required in radio wave communication as in the case of infrared communication, so the remote control is not necessarily directed to the toilet. There is no need to do so, the degree of freedom of the installation of the remote control is increased, less current consumption is required, and in some cases, the cleaning device body in the booth can be operated by remote control operation even from outside the booth. Is obtained.

  On the other hand, in the case of a communication method using radio waves, radio waves penetrate the booth wall, so when a remote control is operated in one booth, the operation signal from the remote control is the main body of the cleaning device in another booth The problem of cross-talk that is received at is a big problem.

  Therefore, the remote control in the same booth and the main body of the cleaning apparatus are associated with each other one-to-one with the identification code, that is, a unique identification code (ID code) is assigned to the remote control in the same booth. The identification code of the remote controller is stored and set on the cleaning device body side, the identification code is transmitted together with the operation signal from the remote control, and the transmitted identification code is set in advance on the cleaning device body side. It is necessary to accept the operation signal from the remote controller only on the cleaning apparatus main body side only when it matches.

Conventionally, as a method for setting the remote control identification code on the cleaning device main body side, when the power is supplied to the cleaning device main body, the cleaning device main body, more specifically, the control unit is shifted to the identification code setting mode, and the predetermined time Patent Document 1 discloses a method in which an identification code is set and stored on the main body side of the cleaning apparatus when an identification code setting execution signal and an identification code are sent from the remote controller.
As another method, a method is known in which the cleaning device main body is shifted to the identification code setting mode by performing an operation different from a normal operation such as a long press of an operation switch provided in the cleaning device main body. .

  However, in the former case, for example, when the power supply of the cleaning device bodies of each booth is all at once due to the power failure recovery after a power failure, all the cleaning device main bodies shift to the identification code setting mode. When the above identification code setting execution signal is transmitted together with the identification code from the remote control in the booth and is received by the cleaning device main body in another booth, the cleaning device main body is in the same booth of the original counterpart. There arises a problem that an identification code of a remote controller different from the remote controller is set.

  Furthermore, if the cleaning device itself automatically shifts to the identification code setting mode for a certain time due to power failure recovery, even if the user operates the remote control in the same booth during that time, the cleaning device body operates in response to the operation signal. There is an inconvenience that the state of not performing the operation, that is, the state in which the cleaning device main body side does not accept the operation signal of the remote control and the normal operation of the remote control does not work occurs.

  On the other hand, in the latter case, when the operation switch is mischievous by the user in a public toilet or the like, the cleaning device main body unintentionally shifts to the identification code setting mode, and the cleaning device main body is not intended. There is a possibility of setting an identification code.

  By the way, in the case of radio wave communication, two-way communication is generally performed between a remote controller and a corresponding device body, and even in a hot water cleaning apparatus, such two-way communication is performed between the remote controller and the cleaning apparatus body. Specifically, it is convenient to transmit a signal from the remote control to the cleaning device body and to transmit a response signal corresponding to the signal from the cleaning device body to the remote control. In this way, it can be confirmed that the operation signal from the remote controller has been received on the main body side of the cleaning apparatus.

  However, in this case, it is necessary to assign a unique identification code to the cleaning device main body side, and to set and store the identification code also on the remote control side. In each of the cleaning device main body and the remote control, The problem is how to set each other's identification code.

  The above problems are particularly serious when radio communication is performed between the remote control and the cleaning device main body, but the same problem is not the same as in the case of radio communication in the case of infrared or other communication methods. Inherent.

As prior art to the present invention, the following patent document 2 discloses a specific operation for a “stop” switch that is normally operated in a state where a user is seated on a toilet seat by a combination signal of a specific operation switch and a seating sensor. In addition, it is disclosed that the main body of the cleaning apparatus is shifted to the identification code setting mode and the identification code of the remote controller is set in the main body of the cleaning apparatus by the non-seating signal from the seating sensor.
However, what is disclosed in Patent Document 2 is to shift the cleaning apparatus main body to the identification code setting mode by a switch operation, and the method is different from the present invention.

JP 2005-184115 A JP-A-11-140942

  The present invention is based on the above circumstances, and an object of the present invention is to provide a hot water cleaning device in which an unintended remote-side identification code is not erroneously set in the cleaning device body.

  Thus, according to the first aspect of the present invention, there is provided a warm water cleaning apparatus comprising a cleaning device main body installed in a toilet and a remote controller for transmitting an operation signal and remotely operating the cleaning device main body. Identification code setting for setting an identification code unique to the remote controller corresponding to the cleaning device main body based on a seating detection signal from a seating sensor within a predetermined time after power supply to the cleaning device main body to the cleaning device main body It is supposed to shift to the mode.

  According to a second aspect of the present invention, in the first aspect, the cleaning device main body transmits a response signal to the remote control in response to an operation signal from the remote control, and the remote control is connected to the cleaning device main body. A unique identification code is set in the remote control, and the remote controller sets an identification code for the cleaning device main body in the remote control while the cleaning device main body is in the identification code setting mode. When shifting to the code setting mode, the remote control and the cleaning device main body exchange mutual identification codes, and the remote control and the cleaning device main body each set the other party's identification code to themselves. It is characterized by being.

Effects and effects of the invention

  As described above, the present invention does not immediately shift to the identification code setting mode after the cleaning apparatus main body is supplied with power, and is specific to the corresponding remote controller based on the seating detection signal from the seating sensor within a predetermined time after power supply. The operation is shifted to an identification code setting mode in which the identification code is set in the cleaning apparatus main body.

  According to the present invention, for example, the cleaning apparatus body does not automatically shift to the identification code setting mode due to a power failure recovery after a power failure, and the operator actively moves the cleaning apparatus body to the identification code setting mode. A seating detection signal is transmitted from the seating sensor by sitting on the toilet seat with a will and holding the hand or the like over the seating detection sensor, and then the cleaning apparatus main body is shifted to the identification code setting mode.

  Therefore, it is possible to effectively prevent the remote control identification code that is not intended by the cleaning device body from being set in error, and the remote control identification code in the same booth that is the original counterpart is used as the cleaning device body. Can be set and stored.

  For example, in some toilets, when a user stands in front of the toilet, the human body detection sensor detects this and automatically opens the toilet lid. In this case, the signal from the human body detection sensor and the cleaning device main body Although it is conceivable that the main body of the cleaning device is shifted to the identification code setting mode in combination with the power-on (power supply), in this case, the user intends to shift to the identification code setting mode. Even if not, if the user happens to stand in front of the toilet bowl, the human body detection sensor may detect this, which is insufficient in terms of certainty.

  On the other hand, since the seating sensor is usually inside the toilet lid and does not detect seating unless the toilet lid is opened, the cleaning device main body can be more surely shifted to the identification code setting mode based on the user's intention. Can do.

Further, the present invention has an advantage that the cleaning apparatus main body can be shifted to the identification code setting mode and the identification code can be set even if the cleaning apparatus main body side is not particularly equipped with a switch for shifting to the identification code setting mode. Have.
The present invention has a great effect when applied to radio wave communication, but can also be applied to a hot water cleaning apparatus using infrared or other communication methods.

  Next, according to claim 2, the cleaning device main body transmits a response signal to the remote control in response to an operation signal from the remote control, and the remote control sets an identification code unique to the cleaning device main body to itself. When the remote control shifts to the identification code setting mode for setting the identification mode of the cleaning device while the cleaning device is in the identification code setting mode, the identification code is exchanged between the remote control and the cleaning device. In addition, the remote controller and the cleaning apparatus main body each set the other party's identification code to themselves.

  By doing so, it is possible to effectively prevent an accidental setting of an identification code different from that of the other party unintentionally in each of the cleaning device main body and the remote control. The other party's identification code can be set reliably.

It is a general view of the toilet which installed the toilet bowl provided with the warm water washing device which is one embodiment of the present invention in each booth. It is a figure of the toilet bowl and warm water washing apparatus installed in the booth of FIG. It is a figure of the principal part of the embodiment. It is a flowchart which shows the execution procedure of the identification code setting by the washing | cleaning apparatus main body side in the embodiment. It is a flowchart which shows the execution procedure of the identification code setting by the side of the remote control in the embodiment.

Next, embodiments of the present invention will be described in detail with reference to the drawings.
In FIG. 1, 10 is a booth provided side by side in the toilet, and a toilet 12 is installed in each booth 10.
FIG. 2 shows the toilet 12 installed in each booth 10 together with a hot water cleaning device.
As shown in the drawing, the toilet (Western style toilet) 12 includes a toilet body 14, a toilet seat 16, a toilet lid 18 and a washing tank 20.
Reference numeral 22 denotes a tank cover in the cleaning tank 20, in which an inner tank (not shown) for storing cleaning water is accommodated.

The toilet 12 is integrally incorporated with a cleaning device body 26 having a pair of cleaning nozzles 24 for injecting cleaning water to a local body part and cleaning, and a pump for supplying hot water to the cleaning nozzle 24.
The wall W is provided with a remote controller 28 that constitutes a hot water cleaning device together with the cleaning device main body 26.
Here, the remote controller 28 transmits an operation signal to the cleaning apparatus body 26 to remotely operate the cleaning apparatus body 26.

The cleaning device main body 26 is also provided with a seating sensor 30 that detects the seating of the user on the toilet seat 16 under the toilet lid 18 opened.
Further, the cleaning device main body 26 is provided with a control unit 32 (see FIG. 3) whose main element is a microcomputer for controlling the operation of the above-described pump and other functional units.

On the other hand, the remote controller 28 is provided with an operation unit 34 having a plurality of switches for performing each operation on the cleaning device body 26 side.
The operation unit 34 is provided with a stop switch 36 for stopping the ejection of cleaning water from the cleaning nozzle 24 and other operations.

The remote controller 28 is also provided with a transmission unit 38 that transmits an operation signal to the cleaning device main body 26, and a reception unit 40 that receives a signal transmitted from the cleaning device main body 26, and transmission control from the transmission unit 38. The control part 41 which has the microcomputer which performs this as a main element is provided.
On the other hand, the cleaning device body 26 is provided with a receiving unit 42 that receives a signal from the remote controller 28 and a transmitting unit 44 that transmits a signal to the remote controller 28.

In the present embodiment, the communication between the remote controller 28 and the cleaning apparatus body 26 is radio wave communication.
That is, various signals are transmitted from the remote controller 28 by radio waves, and signals are transmitted from the cleaning apparatus body 26 to the remote controller 28 by radio waves.

By the way, in such radio wave communication, radio signals from the remote control 28 and the cleaning device main body 26 pass through the booth 10 wall.
Accordingly, radio signals from the remote control 28 and the cleaning device main body 26 in a certain booth reach the cleaning device main body 26 and the remote control 28 in another booth.

  At this time, the signal from the cleaning device main body 26 in another booth is not transmitted to a certain booth so that the cleaning device main body 26 in another booth does not operate due to a signal from the remote control 28 in a certain booth. The remote control 28 in the same booth 10 and the cleaning device main body 26 set a mutual identification code (ID code) so that the remote control 28 in the same booth 10 does not receive it. Signals are exchanged only with the cleaning apparatus main body 26.

In the present embodiment, the setting of the identification code of the remote controller 28 on the cleaning device main body 26 side and the setting of the identification code of the cleaning device main body 26 on the remote control 28 side are performed as follows.
That is, cleaning is performed based on a seating detection signal from the seating sensor 30 within a predetermined time after power is supplied to the cleaning device body 26 by inserting the plug 48 into the outlet 46 in FIG. 2 or by turning on the power switch. More specifically, the apparatus main body 26 shifts to an identification code setting mode for the controller 32 of the cleaning apparatus main body 26 to set the identification code of the remote controller 28.

  Then, when the cleaning device main body 26 is in the identification code setting mode, when the remote controller 28 shifts to the identification code setting mode for setting the identification code of the cleaning device main body 26, by exchanging the identification code information with each other, The cleaning device body 26 sets the identification code of the remote controller 28, and the remote controller 28 sets the identification code of the cleaning device body 26.

4 and 5 show a specific execution procedure at that time.
Here, when the microcomputer of the control unit 32 in the cleaning device body 26 waits for the completion of the initial operation and detects 5V in the microcomputer input (steps S10 and S12), the process proceeds to step S14, and whether or not the seating sensor 30 has detected the seating. judge.

In this step S14, when it is determined that the seating sensor 30 has detected the seating for 10 seconds continuously, the process may proceed to step S20. However, in this embodiment, the process proceeds to step S16 and the seating sensor 30 continues. It is then determined whether 30 is not detected for 5 seconds.
In step S14, if the seating sensor 30 has not detected the seating for 10 seconds continuously, the process proceeds to step S24 and the normal mode is executed. That is, if seating is not detected within a predetermined time after power supply, the cleaning apparatus body 26 executes the normal mode without shifting to the identification code setting mode.
Although the predetermined time after the power supply is 10 seconds here, it is of course possible to set this to another time.

If the result of determination in step S16 is that the seating sensor 30 has not been detected for 5 seconds, the process proceeds to the next step S18, where input determination of the seating sensor 30 is again made.
Specifically, it is determined whether or not the seating sensor 30 has detected seating for 5 seconds thereafter. As a result, when seating detection is detected for 5 seconds, the process proceeds to the pairing mode in step S20 for the first time.
If it is not determined in step S16 that the 5-second sitting is not detected, and if it is not determined in step S18 that the 5-second sitting is detected, the process proceeds to step S24, and the normal mode is executed.

  In the present embodiment, the pairing mode of step S20 is first satisfied by satisfying the respective conditions of 10-second seating detection by the seating sensor 30, subsequent 5-second seating non-detection, and subsequent 5-second seating detection. The reason for shifting to is to prevent an erroneous identification code from being set on the cleaning device body 26 side.

The seating detection for 10 seconds, the non-detection for the next 5 seconds, and the conditions for the subsequent 5 seconds for the seating detection cannot happen by chance. This can only happen for the first time when seating is detected by 30. Therefore, it is possible to reliably prevent an erroneous identification code from being set by shifting to the pairing mode through these steps. it can.
Note that the numerical values of 10 seconds, 5 seconds, and 5 seconds in steps S14, S16, and S18 are merely examples, and the respective detection or non-detection times can be set to other times.

In this pairing mode, the cleaning device main body 26 shifts to an identification code setting mode for setting the identification code of the remote controller 28, and when in the identification code setting mode, the identification of the cleaning device main body 26 is performed on the remote control 28 side. In the mode in which the cleaning device body 26 and the remote control 28 exchange each other's identification codes when the code shifts to the identification code setting mode for setting the code in the remote control 28, the cleaning device body 26 identifies the remote control 28 by the exchange. Set the code to itself.
Specifically, the identification code of the remote controller 28 is stored and set in the control unit 32 of the cleaning apparatus body 26 based on the identification code setting execution signal and the identification code transmitted from the remote controller 28.
The transition to the identification code setting mode on the remote controller 28 side will be described later.

  When the identification code information is successfully exchanged between the cleaning device main body 26 and the remote controller 28, or when 60 seconds have passed without any identification code information exchange due to some trouble, the normal mode of step S24 is entered. Transition.

In this normal mode, when the operation signal from the remote controller 28 is received by the cleaning apparatus body 26 together with the identification code of the remote controller 28, the cleaning apparatus body 26 performs a cleaning operation and other operations according to the operation signal.
On the other hand, when the exchange of the identification code is not successful in step S22 and 60 seconds have not elapsed, the process returns to step S20 and is executed again.

On the other hand, FIG. 5 shows an identification code setting procedure on the remote controller 28 side.
As shown in the figure, on the remote controller 28 side, when the remote controller 28 is in the normal mode, for example, when the stop switch 36 is continuously pressed for 10 seconds (steps S26, S28), the control unit 41 of the remote controller 28 there. Shifts to the pairing mode in step S30.

When the transition to the pairing mode on the remote controller 28 side is performed within 60 seconds after the transition to the pairing mode on the cleaning apparatus body 26 side, the identification code between the cleaning apparatus body 26 and the remote controller 28 is mutually used. Exchange information.
Based on the identification code setting execution signal and the identification code from the cleaning device body 26, the identification code of the cleaning device body 26 is set in the control unit 41 of the remote controller 28.

When the information exchange is successful on the remote controller 28 side or when 10 seconds have passed without information exchange, the process returns to step S26 and the subsequent steps are executed again.
On the other hand, when the exchange of the identification code is not successful and 10 seconds have not elapsed, the process returns to step S30, and step S30 is executed again.

  According to the present embodiment as described above, it is possible to effectively prevent the identification code of the remote controller 28 that is not intended by the cleaning apparatus body 26 from being set in error, and the same as the original counterpart. The identification code of the remote controller 28 in the booth 10 can be set and stored in the cleaning device main body 26.

  Further, according to the present embodiment, the cleaning device main body 26 is shifted to the identification code setting mode and the identification code is set even if the cleaning device main body 26 is not particularly equipped with a switch for shifting to the identification code setting mode. Can be made.

  Further, according to the present embodiment, in each of the cleaning device main body 26 and the remote control 28, it is possible to effectively prevent an accidental setting of an identification code different from the other party unintentionally. In each of the remote controllers 28, the original counterpart identification code can be set reliably.

  Although the embodiment of the present invention has been described in detail above, this is merely an example, and the present invention can be applied to the case where infrared communication is performed between the remote controller and the cleaning apparatus main body depending on the case. The present invention can be configured in various forms without departing from the scope.
