The toilet device 1 is a sitting type Western-style toilet device fixed to a floor, a wall, or the like in a toilet space. The main body 10 of the toilet bowl device 1 is designed so that the bowl 12 opened upward is surrounded by the skirt portion 11, and the upper side of the bowl 12 is freely laid down with respect to the opening surface of the bowl 12. It is provided with a toilet seat 24 and a toilet lid 20 having the same rotation axis. It should be noted that individual rotation axes may be used so that they can be interlocked with each other.

In the internal space of the skirt portion 11, a toilet bowl cleaning portion 13 for draining the sewage in the bowl 12 and supplying washing water into the bowl 12 from the water supply port 14 to clean the inside of the bowl 12 is arranged. The toilet bowl cleaning unit 13 has a water supply mechanism and a drainage mechanism.

The water supply mechanism is arranged in the middle of the water supply port 14, the wash water supply path 15 that supplies the wash water supplied from the water pipe (not shown) into the bowl 12 through the water supply port 14, and the wash water supply path 15. It is provided with a water supply valve 16 that supplies or shuts off the washing water to the bowl 12.

The drainage mechanism shown in FIG. 2A has a tubular bent trap 17 connected so as to extend rearward from the bottom of the bowl 12, the trap 17 extending further downward and connecting to the drainage port 18. Has been done. Examples of this type of drainage mechanism include a siphon type, a siphon set type, and a siphon vortex type, which are considered to be a mechanism in which a drainage state or a sealed state is formed by a siphon action.

Further, the drainage mechanism may have a structure having a movable trap 17A as shown in FIG. 2 (b). The trap 17A is rotated in the direction of an arrow by a driving unit (not shown) to form a drainage state or a water sealing state. The trap 17A in the illustrated example is in the position in the sealed state, and in the drainage state, the trap 17A rotates so that the open end of the trap 17A faces the drain port 18. The trap 17A is surrounded by a trap case (not shown) so that sewage and odor do not leak to the outside.

Further, a drainage mechanism that is neither a siphon type nor a movable type, for example, a wash-off type drainage mechanism can be applied to the toilet bowl device 1.

Further, in the figure, an example is shown in which the toilet bowl device 1 is a tankless type directly connected to the water supply without a water washing tank (low tank), but a water washing tank may be provided.

Further, as shown in FIG. 1, the toilet device 1 includes a toilet lid open / close detection unit 21, a toilet lid drive unit 22, and a toilet lid operation unit 23, as described above. The toilet lid operation unit 23 is an operation unit that receives an opening / closing instruction from the user to the toilet lid drive unit 22. Further, the toilet device 1 includes a toilet seat 24, a toilet seat open / close detection unit 25 that detects the opening / closing of the toilet seat 24, a toilet seat drive unit 26 that opens / closes the toilet seat 24, and a toilet seat operation unit 27 that receives an opening / closing instruction to the toilet seat drive unit 26. In addition, a seating detection unit 28 is also provided.

Each of the toilet lid operation unit 23 and the toilet seat operation unit 27 may be configured with switches for opening and closing individually, or may be capable of alternately switching opening and closing with one switch. In the latter case, it may be determined whether the instruction is open / closed in cooperation with the toilet lid open / close detection unit 21 (toilet seat open / close detection unit 25) and the software.

As the seating detection unit 28, for example, a load sensor for detecting seating / leaving, an infrared sensor for detecting seating / leaving from the vicinity of the rotation shaft portion of the toilet seat 24, and the like, which are built in the toilet seat 24, are adopted. As the toilet lid open / close detection unit 21 and the toilet seat open / close detection unit 25, those configured to detect the open / closed state by the opening angle are adopted.

The toilet lid drive unit 22 and the toilet seat drive unit 26 are each composed of a motor or the like. The toilet lid drive unit 22 electrically opens and closes (tilts) the toilet lid 20 when there is an instruction from the toilet lid operation unit 23, and the toilet seat drive unit 26 receives an instruction from the toilet seat operation unit 27. The toilet seat 24 is electrically opened and closed (tilted). The example shown in FIG. 1 has a configuration in which a drive unit (motor) is provided in each of the toilet lid 20 and the toilet seat 24, but may be configured to be individually driven by one motor.

In the present specification, in both the toilet lid 20 and the toilet seat 24, the state in which the toilet lid 20 and the toilet seat 24 are upright is referred to as an open state, and a state in which the toilet lid 20 is tilted substantially horizontally and is substantially parallel to the opening surface of the bowl 12 is referred to as an open state. It is called a closed state.

In this toilet device 1, if both the toilet lid 20 and the toilet seat 24 are in the open state when the toilet lid 20 is instructed to close by the toilet lid operation unit 23 or the like, the toilet seat 24 first closes and then closes. The toilet lid 20 closes in conjunction with the closing action of the toilet seat 24. The closing operation of the toilet lid 20 may be started after the toilet seat 24 is closed, or may be during the closing operation.

If both the toilet seat 24 and the toilet lid 20 are in the closed state when the toilet seat operation unit 27 or the like instructs to open the toilet seat 24, the toilet lid 20 first opens the toilet lid 20 and then the toilet lid 20. The toilet seat 24 opens the toilet seat 24 so as to be linked to the opening operation. The opening operation of the toilet seat 24 may be started after the opening of the toilet lid 20 or during the opening operation.

Further, the toilet lid 20 and the toilet seat 24 can be opened and closed manually regardless of the toilet lid operation unit 23 and the toilet seat operation unit 27, respectively. It is detected by the unit 21 and the toilet seat open / close detection unit 25.

The toilet device 1 may be further provided with various functional devices such as a deodorizing device for deodorizing the inside of the bowl 12, a heating device for heating the toilet seat 24, and a local cleaning device for locally cleaning the toilet seat 24.

Further, the toilet device 1 includes a cleaning operation unit 29. The cleaning operation unit 29 includes a stool cleaning button 29a and a urine cleaning button 29b that output cleaning instructions to the toilet bowl cleaning unit 13 via a control unit 5 described later.

It is desirable that the cleaning operation unit 29 is arranged in either the main body operation unit (not shown) or the remote controller (not shown). These are also provided with operation switches and operation buttons that allow various operations and settings. As the remote controller, an infrared communication remote controller is preferably used. Needless to say, the remote controller is provided with a transmitting unit (not shown), and the main body 10 is provided with a receiving unit (not shown).

The operation of the cleaning operation unit 29 acts as a cleaning instruction means, and further, the state change from sitting to leaving the seat detected by the seating detection unit 28 also acts as a cleaning instruction means (trigger for starting cleaning). That is, when a person stands up from the toilet seat 24 while sitting, automatic cleaning is performed instead of operating the cleaning button.

Further, the cleaning instruction may be output by one cleaning button without providing both the stool cleaning button 29a and the urine cleaning button 29b. That is, in that case, the amount of washing water in the bowl 12 is not distinguished between the large capacity for stool and the small capacity for urine, and is only one type of the large capacity for stool.

The toilet device 1 controls the above-mentioned control targets (water supply valve 16 of the toilet cleaning unit 13, toilet lid drive unit 22, toilet seat drive unit 26, etc.), while the cleaning operation unit 29, toilet lid open / close detection unit 21, and toilet seat open / close detection are detected. A control unit 5 that receives an output signal such as a unit 25 and a seating detection unit 28 is provided. The control unit 5 includes a processor such as a CPU and an MPU and various programs. The toilet device 1 further includes a time measuring unit 6 and a power supply unit (not shown).

Further, the toilet bowl device 1 includes a notification unit 7 composed of a speaker or the like that notifies an abnormality or state of the device and guidance by sound or voice synthesis. The notification unit 7 may be configured to include a display such as an LED in place of or in addition to the sound output unit.

Next, the basic operation of the toilet bowl device 1 will be described with reference to the operation flowcharts of FIGS. 3 and 4. These operations are operations by the control unit 5 when the toilet lid operation unit 23 gives an instruction to close the toilet lid 20.

In the following operation description, the detection of the open / closed state of the toilet lid 20 and the detection of the open / closed state of the toilet seat 24 are performed by each detection unit, but the description of the operation of those detection units will be omitted. Further, although the opening / closing operation of the toilet lid 20 and the opening / closing operation of the toilet seat 24 are performed by each drive unit, the description of the operation of those drive units will be omitted.

First, the operation shown in the flowchart of FIG. 3 (steps S100 to S108) will be described. In the following description, the description of "step SXXX" is abbreviated as "SXXX" having only a code.

When the toilet lid 20 is instructed to close the toilet lid 20 by the toilet lid operating unit 23 when the toilet lid 20 is open, the toilet lid driving unit 22 starts the closing operation of the toilet lid 20 (S100, S101). If the toilet seat 24 is also in the open state, the closing operation of the toilet seat 24 starts first, and then the closing operation of the toilet lid 20 starts, as described above.

If there is no cleaning instruction by the cleaning operation unit 29 until the toilet lid 20 is closed, that is, by the end of the closing operation of the toilet lid 20, it is notified that the toilet lid 20 is closed after the toilet lid 20 is closed (S102). , S103, S104). It should be noted that "until the end of the closing operation of the toilet lid 20" naturally includes from the start to the end of the closing operation when the toilet seat 24 is closed.

Further, if there is a cleaning instruction before the toilet lid 20 is closed, it is notified that cleaning is suspended at the instruction timing (N of S102, N of S103, Y of S102, S105). The washing is suspended until the stool lid 20 is closed, and when the stool lid 20 is closed, the closing of the stool lid 20 is notified, and then the washing is started (S106 to S108).

In this way, if the cleaning operation unit 29 receives a cleaning instruction during the closing operation of the toilet lid 20 (with the toilet seat 24) by the closing operation of the toilet lid operation unit 23, that is, before the toilet lid 20 is closed, the cleaning is performed. It is not executed immediately, but is executed after the toilet lid 20 is closed. Therefore, washing in a state where the stool lid 20 is not closed can be avoided, and the diffusion of contaminants contained in the stool in the bowl 12 can be prevented.

It should be noted that the washing may be suspended at least when a washing instruction is given by the stool washing button 29a. When there is a cleaning instruction by the urine cleaning button 29b, the cleaning may not be suspended and may be executed immediately. Further, when there is a cleaning instruction by the urine cleaning button 29b and the cleaning is in the open state, the cleaning may not be suspended and may be executed immediately.

Next, the operation shown in the flowchart (steps S200 to S206) for the operation of FIG. 4 will be described.

When the toilet lid 20 is instructed to close the toilet lid 20 by the toilet lid operating unit 23 when the toilet lid 20 is open, the toilet lid driving unit 22 starts the closing operation of the toilet lid 20 (S200, S201). If the toilet seat 24 is also in the open state, the closing operation of the toilet seat 24 starts first, and then the closing operation of the toilet lid 20 starts, as described above.

If there is no cleaning instruction by the cleaning operation unit 29 until the toilet lid 20 is closed, that is, by the end of the closing operation of the toilet lid 20, it is notified that the toilet lid 20 is closed after the toilet lid 20 is closed (S202). , S203, S204). As described above, "until the end of the closing operation of the toilet lid 20" includes the period from the start to the end of the closing operation when the toilet seat 24 is closed.

Further, if there is a cleaning instruction before the toilet lid 20 is closed, cleaning is suspended and canceled at the instruction timing, and the notification is notified (N of S202, N of S203, Y of S202, S205, S206). ). Since no special treatment for canceling the cleaning is performed, the cleaning cancellation is indicated by a broken line (S205).

In this way, if the cleaning operation unit 29 receives a cleaning instruction during the closing operation of the toilet lid 20 (with the toilet seat 24) by the closing operation of the toilet lid operation unit 23, that is, before the toilet lid 20 is closed, the cleaning is suspended. State continues. That is, the washing is canceled. Therefore, washing of the stool lid 20 in the open state can be avoided, and the diffusion of contaminants contained in the stool in the bowl 12 can be prevented. Since the cancellation of the cleaning is notified, the user who has received the notification may perform the cleaning operation again in order to perform the cleaning.

The toilet device 1 may adopt either the operation mode shown in FIG. 3 (after holding, washing) or the operation mode shown in FIG. 4 (continuing the holding state, that is, canceling washing). The user may be able to switch by setting operation.

Next, the operation mode shown in FIG. 5 will be described. It should be noted that this operation can also be executed by the toilet bowl device 1 shown in FIG.
First, a schematic configuration will be described.

In this operation mode, when the cleaning operation by the cleaning operation unit 29 is performed while the toilet lid 20 is in the open state, the control unit 5 suspends the cleaning by the cleaning operation. After that, the control unit 5 causes the toilet bowl cleaning unit 13 to start cleaning after the toilet lid 20 is closed. In this embodiment, the toilet lid driving unit 22 electrically closes (closes) according to the operation instruction of the toilet lid operating unit 23.

Then, it will be described in detail with reference to the flowchart of FIG. 5 (steps SS300 to S309). This operation is an operation by the control unit 5 when a cleaning instruction is given by the cleaning operation unit 29.

When a cleaning instruction is received, this is first notified, then the open / closed state of the toilet lid 20 is determined, and if it is in the closed state, the bowl 12 is immediately washed (S300, S301, N of S302, S309).

If the toilet lid 20 is in the open state, the timer for a predetermined time is activated, and if the toilet lid 20 is closed by the toilet lid operation unit 23 before the time is up, the toilet lid drive unit 22 of the toilet lid 20 will be used. The closing operation is executed (Y of S302, S303 to S306). Also in this case, if the toilet seat 24 is in the open state, the toilet seat 24 first closes and then the toilet lid 20 closes.

Then, the closing of the toilet lid 20 is notified, and the bowl 12 is washed (S307, S308).

Further, when the time is up without closing the toilet lid 20, cleaning is executed at that timing (Y in S304, S308). Instead of immediately cleaning, the toilet lid 20 may be further urged to close, and cleaning may be started after a time delay.

It should be noted that the cleaning may not be executed and the cleaning may be canceled (the flow of the broken line of Y in S304). As a safer measure to prevent scattering, the latter (flow of the broken line) may be used, and in that case, a notification such as prompting the closing operation of the toilet lid 20 and then cleaning may be performed.

In this way, if the toilet lid operation unit 23 closes the toilet lid operation unit 23 within a predetermined time after the cleaning operation unit 29 is instructed to clean the cleaning operation unit 29, the cleaning is suspended and the cleaning is performed after the toilet lid 20 is closed. Spread is avoided. The cleaning may be started by the cleaning instruction of the cleaning operation unit 29, and in that case, the cleaning is interrupted by the closing operation of the toilet lid 20.

As described above, even when the closing operation by the toilet lid operation unit 23 and the cleaning instruction by the cleaning operation unit 29 are instructed in this order, the cleaning instruction by the cleaning operation unit 29 and the closing operation by the toilet lid operation unit 23 are instructed in this order. Even if there is, the diffusion of droplets (pollutants) from the inside of the bowl 12 is prevented.

FIG. 5 assumes that the toilet lid operation unit 23 closes the toilet lid 20 after the cleaning instruction, and the toilet lid 20 is closed by the toilet lid driving unit 22. However, when the toilet lid 20 is manually closed after the cleaning instruction. Also, the same operation mode may be applied.

That is, when the toilet lid 20 is manually (finger or the like) closed after the cleaning operation, the cleaning may be suspended while the toilet lid 20 is being closed, and the cleaning may be performed when the toilet lid 20 is closed. In this case, since the operation of the toilet lid 20 does not depend on the toilet lid operation unit 23, the toilet lid open / close detection unit 21 detects the state change of the toilet lid 20 from the on state to the off state of the toilet lid 20. It suffices if it is determined that the closing operation corresponding to S305 in FIG. 5 has been performed.

The toilet device 1 is not limited to the above, and the toilet seat 24 and the toilet lid 20 may be interchangeable as a unit. In particular, the toilet device 3 to which the toilet seat device 30 as shown in FIG. 6 is retrofitted (or replaced) may be used. Based on FIGS. 6A and 6B, the basic configuration of the toilet bowl device 3 according to another embodiment of the present invention will be described. In this embodiment, the movable trap 17A is illustrated in FIG. 6 (b), but the toilet bowl body may have a siphon type trap 17 (see FIG. 2 (a)) or another method. Is also applicable.

Specifically, the toilet device 3 outputs a cleaning instruction to the bowl 12, the toilet cleaning unit 13 that supplies cleaning water to the bowl 12 to clean the inside of the bowl 12, the toilet seat device 30, and the toilet cleaning unit 13. It includes a cleaning operation unit 29, a control unit 5, a timing unit 6, and a notification unit 7.

The toilet seat device 30 is a separate body that can be attached to and detached from the toilet bowl main body (a portion excluding the toilet seat device 30) of the toilet bowl device 3. The toilet seat device 30 includes a toilet lid 40, a toilet lid open / close detection unit 41, a toilet lid drive unit 42, a toilet lid operation unit 43, a toilet seat 44, a toilet seat open / close detection unit 45, a toilet seat drive unit 46, a toilet seat operation unit 47, and a seating detection unit. It includes 48, a bowl cleaning operation unit 49, a toilet seat side control unit 35, a timing unit 36, and a notification unit 37. Further, it is possible to send and receive electric signals between the toilet seat device 30 and the toilet bowl main body.

Since the configuration of the toilet device 3 (toilet bowl main body) excluding the toilet seat device 30 is almost the same as that of FIG. 1, detailed description thereof will be omitted. Further, the toilet lid 40, the toilet lid open / close detection unit 41, the toilet lid drive unit 42, the toilet lid operation unit 43, the toilet seat 44, the toilet seat open / close detection unit 45, the toilet seat drive unit 46, and the toilet seat operation unit 47, which are included in the toilet seat device 30. The seating detection unit 48 is almost the same as that of FIG. 1, and the description thereof will be omitted.

The toilet seat device 30 of FIG. 5 is configured to be able to output a cleaning instruction of the bowl 12 to the toilet bowl cleaning unit 13 from the toilet seat device 30 side. Specifically, in the toilet seat device 30, when the bowl cleaning operation unit 49 gives an instruction for cleaning, the toilet seat side control unit 35 receives the instruction, and the toilet seat cleaning unit 13 is moved through the control unit 5 on the toilet body side. The bowl 12 can be washed in a controlled manner. Further, the toilet seat side control unit 35 may be configured to directly control the toilet bowl cleaning unit 13.

As shown in FIG. 5, the toilet device 3 includes not only the bowl cleaning operation unit 49 on the toilet seat device 30 side but also the cleaning operation unit 29 on the main body side. That is, the one shown in FIG. 6 is configured so that any of the cleaning operation unit 29 and the bowl cleaning operation unit 49 can give a cleaning instruction. Further, the cleaning operation unit 29 may not be provided on the main body side, and the cleaning instruction may be given only by the bowl cleaning operation unit 49. It is desirable that the bowl cleaning operation unit 49 also has a stool cleaning button and a urine cleaning button.

The operation of the bowl cleaning operation unit 49 acts as a bowl cleaning instruction means, and further, the state change from sitting to leaving the seat detected by the seating detection unit 48 also acts as a bowl cleaning instruction means. That is, when the person stands up from the toilet seat 44 while sitting, automatic cleaning is performed instead of operating the cleaning button.

Similar to the toilet device 1 of FIG. 1, the toilet device 3 can also perform the operations shown in FIGS. 3 to 5. That is, when the closing operation by the toilet lid operation unit 43 and the cleaning instruction by the bowl cleaning operation unit (cleaning operation unit 29 or bowl cleaning operation unit 49) are instructed in this order, the operation of FIG. 3 or FIG. 4 is executed. Further, when a cleaning instruction is given by the bowl cleaning instruction means (cleaning operation unit 29 or the bowl cleaning operation unit 49) and an instruction is given in the order of the closing operation by the toilet lid operation unit 43, the operation of FIG. 5 is executed.

As described above, in the case corresponding to FIGS. 3 and 4, the toilet seat side control unit 35 of the toilet device 3 outputs the following instructions to the toilet body. That is, when the toilet seat side control unit 35 receives a cleaning instruction from the bowl cleaning instruction means by the time the closing operation of the toilet lid 40 based on the closing operation of the toilet lid operation unit 43 is completed, the toilet bowl cleaning unit 35 at that timing. Instruct the toilet bowl body to suspend cleaning by 13.

Further, in the case corresponding to FIG. 5, the toilet seat side control unit 35 of the toilet device 3 outputs the following instruction to the toilet body. That is, when the toilet lid 40 is in the open state and the bowl cleaning instruction means gives a cleaning instruction, the toilet seat side control unit 35 suspends the cleaning. Then, the toilet seat side control unit 35 then instructs the toilet bowl body to start the closing operation of the toilet lid 40 when the toilet lid 40 is closed, and to start cleaning after the toilet lid 40 is closed.

Similar to the toilet device 1 shown in FIG. 1, the toilet device 3 has a closed state of the toilet lid 40 even when the operation of closing the toilet lid 40 and the operation of cleaning the toilet bowl are performed in order or vice versa. Since it is washed with a toilet, it is possible to avoid scattering of pollutants.
