Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The toilet apparatuses 1 and 3 described below basically clean the toilet bowl 12 in a closed state of the toilet lid 20 from the viewpoint of preventing the diffusion of the pollutant contained in the excrement. Therefore, if the toilet lid 20, 40 is not closed when there is a washing instruction, the closing operation of the toilet lid 20, 40 is automatically performed electrically before washing to bring the toilet lid 20, 40 into a closed state, and the normal operation is performed.
First, the outline of the toilet apparatus 1 of the present embodiment will be described below. The toilet device 1 is a device having the structure illustrated in fig. 1 and 2, and can alternatively perform the basic operations of the plurality of modes shown in fig. 3 to 5.
The toilet device 1 includes a toilet bowl 12, a toilet bowl cleaning unit 13 that supplies cleaning water to the toilet bowl 12 and cleans the inside of the toilet bowl 12, a toilet lid 20, a toilet lid opening/closing detection unit 21 that detects opening/closing of the toilet lid 20, and a toilet lid driving unit 22 that opens/closes the toilet lid 20. The toilet apparatus 1 further includes a cleaning instruction means for outputting a cleaning instruction to the toilet cleaning unit 13, a timer unit 6, and a control unit 5. Here, the cleaning instruction means includes means for performing a cleaning operation by a user or means for automatically performing the cleaning operation by a user, and details thereof will be described later.
The toilet apparatus 1 is configured to start the closing operation of the toilet lid 20 by the toilet lid driving unit 22 before the toilet lid 13 is cleaned if the toilet lid 20 is opened when the cleaning instruction given by the cleaning instruction means is given, and to perform the cleaning by the toilet cleaning unit 13 if the toilet lid 20 is closed.
As basic operations, there are a plurality of modes.
In the embodiment illustrated in fig. 3 and 4, when the control unit 5 receives a washing instruction, if the toilet lid 20 is opened, a timer for a predetermined time is started, and if it is detected that the toilet lid 20 is closed before the predetermined time elapses, the toilet washing unit 13 starts washing at the timing. When the closing of the toilet lid 20 is not detected when the predetermined time has elapsed, the control unit 5 causes the toilet cleaning unit 13 to start cleaning at the timing (when the predetermined time has elapsed).
In the embodiment illustrated in fig. 5, when the control unit 5 receives a washing instruction, if the toilet lid 20 is opened, a timer for a predetermined time is started, and when the predetermined time elapses, the toilet washing unit 13 starts washing.
By performing any of the above operations, when the closing operation of the toilet lid 20 is not completed for some reason (the toilet lid 20 is not closed) upon the instruction of cleaning, the toilet bowl 12 is cleaned thereafter without any problem.
Next, the detailed structure, and basic operation of the toilet device 1 will be described.
Fig. 1 to 5 are explanatory views of the toilet apparatus 1. As described above, fig. 3 and 4 are explanatory views of one operation mode, and fig. 5 is an explanatory view of another operation mode. Fig. 2 (a) and (b) are schematic side views schematically showing the inside of the toilet device 1 in two modes of different cleaning modes (structures), and may be any modes.
The toilet device 1 is a western-style toilet device that is fixed to a floor, a wall, or the like in a toilet space. The main body 10 of the toilet apparatus 1 is internally provided with a toilet bowl 12 which is opened upward so as to be surrounded by a skirt 11, and a toilet seat 24 and a toilet cover 20 which are provided with the same rotation axis as each other and are capable of being raised and lowered with respect to an opening surface of the toilet bowl 12 are provided on an upper side of the toilet bowl 12.
A toilet cleaning portion 13 is disposed in the inner space of the skirt portion 11, and the toilet cleaning portion 13 discharges sewage in the toilet bowl 12 and supplies cleaning water into the toilet bowl 12 from a water supply port 14 to clean the inside of the toilet bowl 12. The toilet bowl washing unit 13 has a water supply mechanism and a water discharge mechanism.
The water supply mechanism comprises: a water supply port 14; a washing water supply passage 15 for supplying washing water supplied from a tap water pipe (not shown) into the toilet bowl 12 through the water supply port 14; and a water supply valve 16 disposed in the middle of the washing water supply path 15 to supply or shut off the water supply to the toilet bowl 12.
The water discharge mechanism shown in fig. 2 (a) has a cylindrical curved return water bend 17 connected to extend rearward from the bottom of the toilet bowl 12, and the return water bend 17 extends further downward and is connected to a water discharge port 18. Such a drainage mechanism includes a siphon type, a jet siphon type, a vortex siphon type, and the like, and is a mechanism that forms a drainage state or a water seal state by a siphon action.
Further, as the drainage mechanism, a structure having a movable return water bend 17A as shown in fig. 2 (b) may be used. The return water bend 17A is rotated in the arrow direction by a driving unit (not shown) to form a drainage state or a water seal state. The return water bend 17A of the illustration is positioned in a water-sealing state, and a rotation operation is performed in a water-draining state so that the open end of the return water bend 17A faces the water drain opening 18. In addition, the return water bend 17A is surrounded by a return water bend case (not shown) so that sewage or odor does not leak to the outside.
Further, a drain mechanism other than the siphon type or the movable type, for example, a flush type drain mechanism may be applied to the toilet device 1.
In the drawings, the toilet apparatus 1 is illustrated as a flush tank-free type having no flush tank (low water tank) and a direct connection type water pipe, but a flush tank may be used.
As described above, the toilet device 1 further includes the toilet lid opening/closing detection unit 21 and the toilet lid driving unit 22, and further includes the toilet lid operation unit 23 that receives an instruction to open/close the toilet lid driving unit 22 from the user, as shown in fig. 1. The toilet device 1 further includes a toilet seat 24, a toilet seat opening/closing detection unit 25 that detects opening/closing of the toilet seat 24, a toilet seat driving unit 26 that opens/closes the toilet seat 24, a toilet seat operating unit 27 that receives an instruction to open/close the toilet seat driving unit 26, and a seating detection unit 28.
As the seating detection unit 28, for example, a load sensor incorporated in the toilet seat 24 for detecting seating and unseating, an infrared sensor for detecting seating and unseating from the vicinity of the rotation shaft portion of the toilet seat 24, and the like are used. The toilet lid opening/closing detection unit 21 and the toilet seat opening/closing detection unit 25 are configured to detect an open/closed state based on an opening angle.
The toilet cover driving unit 22 and the toilet seat driving unit 26 are each constituted by a motor or the like. The toilet lid driving unit 22 electrically opens and closes (sets up and puts down) the toilet lid 20 when an instruction is given from the toilet lid operating unit 23, and the toilet seat driving unit 26 electrically opens and closes (sets up and puts down) the toilet seat 24 when an instruction is given from the toilet seat operating unit 27.
In the present specification, the state in which the toilet lid 20 and the toilet seat 24 stand up substantially vertically is referred to as an open state, and the state in which they lie substantially horizontally and are substantially parallel to the opening surface of the toilet bowl 12 is referred to as a closed state.
In the toilet apparatus 1, if the toilet lid 20 and the toilet seat 24 are both in the open state when the instruction of the closing operation of the toilet lid 20 is given by the toilet lid operation unit 23 or the like, the toilet seat 24 is first closed, and after the closing (stop in the closed state), the toilet lid 20 is closed so as to be interlocked with the closing operation of the toilet seat 24. If the toilet seat 24 and the toilet lid 20 are both in the closed state when the instruction of the opening operation of the toilet seat 24 is given by the toilet seat operation unit 27 or the like, the toilet lid 20 is opened first, and after the toilet seat is opened (stopped in the opened state), the toilet seat 24 is opened so as to be interlocked with the opening operation of the toilet lid 20.
The toilet apparatus 1 may be configured to further include various functional devices such as a deodorizing device for deodorizing the inside of the toilet bowl 12, a heating device for heating the toilet seat 24, and a local cleaning device for cleaning a local area.
Further, the toilet apparatus 1 includes a cleaning operation unit 29. The cleansing operation unit 29 includes a stool cleansing button 29a and a urine cleansing button 29b for outputting a cleansing instruction to the toilet cleansing unit 13 via the control unit 5 described later.
Further, the cleaning operation unit 29 is preferably disposed on both the main body operation unit (not shown) and the remote controller (not shown). These are also provided with operation switches, operation buttons, and the like that enable various operations, settings, and the like. As the remote controller, a remote controller using infrared communication is suitable. Of course, the remote controller is provided with a transmitting portion (not shown), and the main body 10 is provided with a receiving portion (not shown).
The operation of the cleaning operation unit 29 functions as a cleaning instruction means, and the change in state from sitting to unseating detected by the sitting detection unit 28 also functions as a cleaning instruction means. That is, when a person stands up from the toilet seat 24 while sitting, automatic cleaning is performed instead of the operation of the cleaning button.
Further, instead of providing both the stool washing button 29a and the urine washing button 29b, a configuration may be adopted in which a washing instruction is output by one washing button. That is, the amount of the cleaning water to the toilet bowl 12 in this case is not large and small, but only large.
The toilet apparatus 1 includes a control unit 5, and the control unit 5 controls the control objects (the water supply valve 16 of the toilet cleaning unit 13, the toilet lid driving unit 22, the toilet seat driving unit 26, and the like) and receives output signals of the cleaning operation unit 29, the toilet lid opening/closing detection unit 21, the toilet seat opening/closing detection unit 25, the seating detection unit 28, and the like. The control unit 5 includes a processor such as a CPU and an MPU and various programs. The toilet device 1 further includes a timer unit 6 and a power supply unit (not shown).
The toilet device 1 further includes a reporting unit 7 including a speaker or the like for reporting an abnormality or a state of the device or guiding the user by sound or sound synthesis. The reporting unit 7 may be configured to output sound instead of or in addition to the sound, and may be configured to include a display such as an LED.
Next, basic operations of the toilet apparatus 1 will be described with reference to flowcharts of fig. 3 to 5. These operations are all operations performed by the control unit 5 when the cleaning instruction means has an instruction to perform cleaning.
The toilet apparatus 1 may be any operation structure that performs any one of the operations shown in fig. 3 to 5 when a cleaning instruction is given, and any one of the operations may be performed by changing the setting of the toilet apparatus 1. In addition, when a cleaning instruction is given by the cleaning operation unit 29 during sitting, the toilet apparatus 1 does not receive the cleaning instruction.
In the following description of the operation, the detection of the open/close state of the toilet lid 20 and the detection of the open/close state of the toilet seat 24 are performed by the respective detection units, but the description of the operation of these detection units is omitted. The opening and closing operations of the toilet cover 20 and the toilet seat 24 are performed by the respective driving units, but the description of the operations of these driving units is omitted.
First, the operation of fig. 3 will be described with reference to flowcharts shown in steps S100 to S113. In the following description, regarding the operation steps of fig. 3 to 5, the portion described as "step s×" is simply referred to as "s×" with only a sign.
When receiving the washing instruction given by the washing instruction unit, the report section 7 reports the situation by, for example, an electronic sound "beep" or the like (S100). Then, the open/close state of the toilet lid 20 is determined, and if the toilet lid is in the closed state, the toilet bowl 12 is immediately cleaned thereafter (no in S101, S111).
Although not shown in fig. 3, after the end of the cleaning in S111, the toilet lid 20 may be opened, and after a certain time from the opening state, the toilet lid 20 in the opened state may be closed, and the toilet lid 20 may be closed to a standby state (a state in which the toilet lid 20 is closed).
The opening operation of the toilet lid 20 after washing is performed to allow the user to confirm the residue of the waste in the toilet bowl 12 after washing. That is, the user does not need to manually open the toilet lid 20 after washing in order to confirm the inside of the toilet bowl 12.
Instead of the above-described delay of a certain time, the system may return to the standby state at a timing when the person is no longer detected by the person sensor. Of course, the user can close the toilet lid 20 by the toilet lid operation unit 23, and thus the user may not return to the standby state automatically.
When the cleaning instruction is received, if the toilet lid 20 is in the open state, a timer for a predetermined time is started (yes in S101, S102). The timer is used to forcibly start the cleaning with a time limit when the toilet seat 24 and the toilet lid 20 are not closed from the result within a predetermined time during the following closing operation of the toilet seat 24 and the toilet lid 20.
In addition, the toilet device 1 also opens and closes the toilet seat 24 by electric power. Accordingly, in the case where the toilet seat 24 is opened in response to the instruction to close the toilet lid 20 based on the washing instruction, the predetermined time is preferably set to a time that takes into consideration both the closing operation of the toilet seat 24 and the closing operation of the toilet lid 20.
After the timer is started, the state of the toilet seat 24 is determined, and if the toilet seat 24 is in the open state, the closing operation of the toilet seat 24 is started (yes in S103, S104). If the toilet seat 24 is not closed until the timer has expired, the report unit 7 reports that the timer has expired and the cleaning is started (no in S105 and S106, yes in S105, S112 and S113).
Since the report at this time is a warning level report for forced cleaning, it is preferable that the report be clearly audible, such as an electronic sound "beep", and that the cleaning be started after the sound is finished so that the sound is not masked by the subsequent cleaning sound.
Then, when the toilet seat 24 is closed after the time elapses, or if the toilet seat 24 is closed at the timing of the washing instruction, the closing operation of the toilet lid 20 is started (yes in S106, no in S103, S107). If the toilet lid 20 is not closed until the timer time has elapsed, the time is reported to have elapsed, and the cleaning is started (NO in S108, S109, yes in S108, S112, S113).
If the toilet lid 20 is closed after the time elapses, the toilet lid 20 is closed by a report such as an electronic sound "beep" different from the time of the washing instruction, and washing of the toilet bowl 12 is performed (yes in S109, S110, S111). In addition, the cleaning may be performed without reporting that the toilet lid 20 is closed. That is, in this case, a report is also made when the toilet lid 20 after the washing instruction is closed (no in S101).
The toilet device 1 basically starts cleaning on condition that the lid 20 is closed, but the cleaning is performed when such time is reached (yes in S105 and yes in S108). As a cause of the time before the toilet seat 24 is closed, for example, a malfunction of the toilet seat driving unit 26 and the toilet seat 24, a case where the toilet seat 24 is stopped by hand in the closing operation, and the like are conceivable. Further, as a cause that the time has come before the toilet lid 20 is closed, for example, a malfunction of the toilet lid driving unit 22 and the toilet lid 20, a case where the toilet lid 20 is stopped by hand during the closing operation, and the like can be considered.
In this case, when the time has elapsed, the cleaning is forced to be performed with priority given to the cleaning instruction regardless of the state of the toilet cover 20 (toilet seat 24). In some cases, the operations of the toilet seat 24 and the toilet lid 20 are stopped according to the user' S intention, but in order to promote the release of the prohibition against the toilet seat 24 and the toilet lid 20 by the user, it is preferable to report that the toilet seat 24 and the toilet lid 20 are not closed (time has arrived) as described above (S112).
As shown in the flowchart (S200 to S214) of fig. 4, the toilet seat 24 and the toilet lid 20 may be individually monitored by a timer as an operation mode of cleaning before the toilet lid 20 is closed.
When the washing instruction is received, the situation is first reported, for example, by an electronic sound "beep" or the like (S200). Then, the open/close state of the toilet lid 20 is determined, and if the toilet lid is in the closed state, the toilet bowl 12 is immediately cleaned thereafter (no in S201, S212). As in the case of fig. 3, after the end of the washing in S212, the toilet lid 20 may be opened, and after a predetermined time from the opening, the toilet lid 20 in the opened state may be closed, and the toilet lid 20 may be closed to a standby state (a state in which the toilet lid 20 is closed).
If the toilet lid 20 is in the open state upon receiving the cleaning instruction, the state of the toilet seat 24 is further determined, and if the toilet seat 24 is in the open state, a timer (timer # 1) for a predetermined time is started (yes in S201, yes in S202, S203). The timer is a timer for monitoring the closing operation of the toilet seat 24 and is used to forcibly start the washing in the case where the toilet seat 24 is not closed.
After the timer is started, the toilet seat 24 is closed (S204). If the toilet seat 24 is not closed until the timer #1 expires, the expiration of the time is reported (NO in S205, S206, YES in S205, S213, S214) to start the cleaning. As described above, in the toilet apparatus 1, as in the example of fig. 3, the cleaning is started under the condition that the lid 20 is closed, but the cleaning is performed before the lid 20 (toilet seat 24) is closed when such a time is reached.
Then, when the toilet seat 24 is closed after the time elapses, or if the toilet seat 24 is closed at the timing of the washing instruction, a timer (timer # 2) for a predetermined time is started and the closing operation of the toilet lid 20 is started (yes in S206, no in S202, S207, S208). If the toilet lid 20 is not closed until the timer #2 expires, the expiration of the time is reported (NO in S209, S210, yes in S209, S213, S214) to start the cleaning.
If the toilet lid 20 is closed after the time is not reached, the toilet lid 20 is closed by a report such as an electronic sound "beep" different from the time of the washing instruction, and washing of the toilet bowl 12 is performed (yes in S210, S211, S212). In addition, it is also possible to report that the cleaning is performed instead of reporting that the toilet lid 20 is closed. That is, in this case, a report is also made when the toilet lid 20 after the washing instruction is closed (no in S201).
As described above, the toilet apparatus 1 starts cleaning under the condition that the lid 20 is closed, as in fig. 3, but in the exception, when such time has come (yes in S205, yes in S209), cleaning is performed before the lid 20 is closed.
Thus, the closing operations of the toilet seat 24 and the toilet lid 20 in the operation of fig. 4 are individually monitored by the timer. Therefore, the closing operation is monitored at different time intervals between the case where only the toilet lid 20 is opened and the case where both the toilet seat 24 and the toilet lid 20 are opened, and the closing operation can be monitored at a more appropriate time, and the cleaning can be performed at a more appropriate timing. For example, if only the toilet lid 20 is open (such as immediately after excretion), the closing operation is monitored by one timer (timer # 2), whereas if both the toilet seat 24 and the toilet lid 20 are open, the closing operation is monitored by both timers (timer # 1+timer # 2).
As described above, in the configurations of fig. 3 and 4, even when the closing of the toilet cover 20 (including the toilet seat 24) is not detected when the time has elapsed, the cleaning can be performed at the timing when the time has elapsed. Therefore, even when the toilet lid 20 is not in the closed state due to a trouble of the toilet seat 24 or the toilet lid 20, a stop of the toilet seat 24 or the toilet lid 20 by a hand of a user or the like, the forced cleaning is not performed in a state where cleaning is not performed when the cause of not being in the closed state is not generated. Therefore, the state in which the cleaning is not performed can be avoided for a long time.
Further, such forced cleaning by the time is possible to scatter the pollutant due to the cleaning in the opened state of the toilet lid 20, but if the user is present, the toilet lid 20 may be closed by hand immediately after the start of cleaning, and there is little problem.
Further, if it is detected that the toilet lid 20 is closed before the time expires, the washing is performed at the detection timing, so that it is possible to avoid the washing being delayed by the timer by more than necessary.
Next, the operation of fig. 5 will be described with reference to flowcharts (S300 to S314).
When the washing instruction is received, the situation is first reported, for example, by an electronic sound "beep" or the like (S300). Then, the open/close state of the toilet lid 20 is determined, and if the toilet lid is in the closed state, the toilet bowl 12 is immediately cleaned thereafter (no in S301, S312).
As in the example of fig. 3, the toilet lid 20 may be opened after the end of washing, and after a predetermined time from the opening, the toilet lid 20 in the opened state may be closed, and the toilet lid 20 may be closed to a standby state (a state in which the toilet lid 20 is closed).
If the lid 20 is in the open state when the cleaning instruction is received, a timer for a predetermined time is started (yes in S301, S302). The timer is used to forcibly start the cleaning when the toilet lid 20 is not closed from the result in a predetermined time during the subsequent closing operation of the toilet lid 20.
After the timer is started, the state of the toilet seat 24 is determined, and if the toilet seat 24 is in the open state, the closing operation of the toilet seat 24 is started (S303, S304). If the toilet seat 24 is not closed until the timer has expired, the time is reported to have expired, and the cleaning is started (S305, NO in S306, yes in S305, S313, S314).
Then, when the toilet seat 24 is closed after the time elapses, or if the toilet seat 24 is closed at the timing of the washing instruction, the closing operation of the toilet cover 20 is started (yes in S306, no in S303, S307). Further, if the toilet lid 20 is not closed until the timer time has elapsed, the time is reported to have elapsed, and the cleaning is started (no in S308, S309, yes in S308, S313, S314).
If the toilet lid 20 is closed after the time elapses, the toilet lid 20 is closed by a report such as a different electronic sound "beep" from the time of the washing instruction, and washing of the toilet bowl 12 is performed (yes in S310, S311, S312). In addition, it may be reported not after the time has elapsed but immediately after the toilet lid 20 is closed.
As described above, in principle, the cleaning is started on condition that the lid 20 is closed, as in fig. 3, but the cleaning may be performed when such time is up (yes in S305, yes in S308).
The operation mode of fig. 5 differs from the operation modes of fig. 3 and 4 in that the cleaning is not performed until the time elapses, and the cleaning is started at the timing when the time elapses (yes in S310, S311, S312) even when the closing operation of the toilet lid 20 is completed within a predetermined time. That is, in the operation mode of fig. 5, if the cleaning instruction is not issued when the toilet lid 20 is in the closed state, cleaning is started only at the timing when the time of the timer has arrived (no at S301, S312).
In this way, since the cleaning is not started regardless of the time up in any case as long as the timer is started, the cleaning start timing can be given by a simpler process. In short, the processing logic shown in fig. 5 is not required, and the cleaning is forcibly started by the interrupt processing based on the arrival of time, so that the programming can be simplified.
In the case of such an operation mode in which cleaning is performed when the time has elapsed, a configuration using two timers may be adopted as in the mode shown in fig. 4.
The operation mode shown in fig. 3 to 5 does not receive the cleaning instruction when the cleaning instruction is given by the cleaning operation unit 29 during sitting, but may be an operation mode in which cleaning is performed during sitting. In this case, the closing operation of the toilet lid 20 is not performed.
The same operation as the operation when the toilet lid 20 is closed (no in S101 and S111 in fig. 1) may be performed as the cleaning operation during sitting, but the cleaning operation may be performed after a predetermined time. That is, in this case, the toilet lid 20 performing the closing operation collides with the seated body, the closing operation of the toilet lid 20 is stopped, and the washing is started by the expiration of the timer (similar to S108, S112, and S113 in fig. 1).
As long as any one of the operation modes of fig. 3 and 4 and the operation mode of fig. 5 described above can be executed, for example, any one of them may be set by a setting operation unit (not shown).
The operations shown in fig. 3 to 5 may be applied to urination, but urination may be eliminated. For example, if the urination cleaning button 29b is operated and the toilet seat 24 is in an open state, it may be determined that urination is performed in the standing position of the man, and the operation of cleaning the toilet seat 24 and the toilet lid 20 may be performed without closing them.
The toilet apparatus 1 shown above is an operation structure in which the closing operation of the toilet lid 20 is started after the closing operation of the toilet seat 24 is completed, but may be an operation structure in which the closing operation of the toilet lid 20 is performed at a time or slightly later than the closing operation of the toilet seat 24.
The toilet device 1 is not limited to the above configuration, and the toilet seat 24 and the toilet cover 20 may be replaced as a single body. In particular, the toilet device 3 may be a toilet device 3 in which the toilet seat device 30 is installed (or replaced) as shown in fig. 6. The basic configuration of the toilet device 3 according to another embodiment of the present invention will be described with reference to fig. 6 (a) and (b). In the present embodiment, the movable return bend 17A is illustrated in fig. 6 (b), but the present invention can be applied to a structure in which the toilet body has the siphon return bend 17 (see fig. 2 (a)) or another structure.
Specifically, the toilet apparatus 3 includes a toilet bowl 12, a toilet bowl cleaning unit 13 that supplies cleaning water to the toilet bowl 12 and cleans the inside of the toilet bowl 12, a toilet seat apparatus 30, a cleaning operation unit 29 that outputs a cleaning instruction to the toilet bowl cleaning unit 13, a control unit 5, a timer unit 6, and a reporting unit 7.
The toilet seat device 30 is configured as a detachable body to the main body of the toilet seat device 3 (a portion other than the toilet seat device 30). The toilet seat device 30 includes a toilet lid 40, a toilet lid opening/closing detection unit 41, a toilet lid driving unit 42, a toilet lid operation unit 43, a toilet seat 44, a toilet seat opening/closing detection unit 45, a toilet seat driving unit 46, a toilet seat operation unit 47, a seating detection unit 48, a toilet bowl cleaning operation unit 49, a toilet seat side control unit 35, a timer unit 36, and a reporting unit 37. Further, electric signals can be transmitted and received between the toilet seat device 30 and the toilet body.
The toilet apparatus 3 (toilet main body) other than the toilet seat apparatus 30 has a structure substantially similar to that of fig. 1, and therefore, a detailed description thereof will be omitted. The toilet lid 40, the toilet lid opening/closing detection unit 41, the toilet lid driving unit 42, the toilet lid operation unit 43, the toilet seat 44, the toilet seat opening/closing detection unit 45, the toilet seat driving unit 46, the toilet seat operation unit 47, and the seating detection unit 48 included in the toilet seat device 30 are also substantially the same as those of fig. 1, and therefore, their descriptions are omitted.
The toilet seat device 30 of fig. 6 is configured to be able to output a cleaning instruction of the toilet bowl 12 from the toilet seat device 30 side to the toilet cleaning unit 13. Specifically, when a cleaning instruction is given from the toilet bowl cleaning operation unit 49, the toilet seat device 30 is configured such that the toilet bowl 12 can be cleaned by receiving the instruction from the toilet seat side control unit 35 and controlling the toilet bowl cleaning unit 13 via the toilet body side control unit 5. The toilet seat side control unit 35 may be configured to directly control the toilet cleaning unit 13.
As shown in fig. 6, the toilet device 3 may be configured to include not only the toilet bowl washing operation portion 49 on the toilet seat device 30 side but also the washing operation portion 29 on the toilet body side. That is, the configuration of fig. 6 is configured such that both the cleaning operation unit 29 and the toilet bowl cleaning operation unit 49 can perform a cleaning instruction. Further, the toilet body may be configured so that the toilet bowl cleaning operation unit 49 can only perform a cleaning instruction without providing the cleaning operation unit 29. The bedpan cleaning operation section 49 preferably has a stool cleaning button and a urine cleaning button.
The operation of the bedpan cleaning operation section 49 functions as a bedpan cleaning instruction means, but the state change from sitting to unseating detected by the sitting detection section 48 also functions as a bedpan cleaning instruction means. That is, when standing up from the toilet seat 44 while sitting, automatic cleaning is performed instead of the operation of the cleaning button.
The toilet device 3 can perform the operations of fig. 3 to 5, etc., similarly to the toilet device 1 of fig. 1. In short, when a cleaning instruction is given from the toilet bowl cleaning instruction means (the toilet bowl cleaning operation section 49), the toilet bowl cleaning section 13 basically cleans the toilet bowl 12 in a state where the toilet bowl cover 40 is closed. When the cleaning instruction is given, the closing operation is performed when the toilet lid 40 is in the open state, but when the time has elapsed as monitored by the timer, the cleaning is performed even if the toilet lid 40 is not in the closed state.
As described above, the toilet seat device 30 includes the toilet seat 44, the toilet lid 40, the toilet lid opening/closing detection unit 41 that detects opening/closing of the toilet lid 40, and the toilet lid driving unit 42 that opens/closes the toilet lid 40. The toilet seat device 30 is a device attached to the toilet seat body, and includes a toilet bowl cleaning instruction means for receiving a cleaning instruction to the toilet seat body, a timer unit 36, and a toilet seat side control unit 35. When the toilet seat device 30 has a cleaning instruction given by the toilet bowl cleaning operation unit 49, if the toilet lid 40 is opened, the toilet lid driving unit 42 starts the closing operation of the toilet lid 40 before the cleaning instruction is output to the toilet body. Further, the toilet seat device 30 outputs a cleaning instruction to the toilet body if the toilet lid 40 is closed.
When receiving a cleaning instruction, the toilet seat side control unit 35 starts a timer for a predetermined time if the toilet lid 40 is opened, and outputs a cleaning instruction to the toilet body at this timing when it detects that the toilet lid 40 is closed before the predetermined time elapses. When the toilet lid 40 is not detected to be closed after a predetermined time has elapsed, the toilet seat side control unit 35 outputs a cleaning instruction to the toilet body at this timing. That is, this operation corresponds to the operation shown in fig. 3 and 4.
Further, the toilet seat side control unit 35 may be configured to start a timer for a predetermined time when the toilet lid 40 is opened upon receiving a cleaning instruction, and to output a cleaning instruction to the toilet body when the predetermined time has elapsed. That is, this action corresponds to the action shown in fig. 5.
Further, the toilet seat device 30 is preferably configured to perform the same operation as the operation performed based on the washing instruction of the toilet bowl washing operation unit 49 even when the washing instruction given by the washing operation unit 29 of the toilet body is received in place of the washing instruction given by the toilet bowl washing operation unit 49.
The timer process of the toilet apparatus 3 may be performed by the timer unit 36 of the toilet apparatus 30, but the timer unit 6 of the toilet main body may be used. Note that various reports may be made by the reporting unit 37 of the toilet seat device 30, but the reporting unit 7 of the toilet body may be used.
The toilet seat device 30 is not limited to the configuration shown in fig. 6. The toilet seat device 30 may be provided with a local cleaning device, or may be provided with a toilet seat operation unit (not shown) that can be operated and set in various manners (e.g., a local cleaning device).
