In this Western-style toilet device 1, when a cleaning instruction is given from the cleaning instruction means, and then when the toilet lid open / close detection unit 21 determines that the toilet lid 20 is in the closed state, the toilet bowl cleaning unit 13 starts cleaning. It is said that it is configured as a toilet.

After the start of cleaning by the toilet bowl cleaning unit 13, the control unit 5 controls the toilet lid opening / closing drive unit 22 to open the toilet lid 20 when it is determined that the cleaning is completed. There are various definitions of "cleaning completed", but the details will be described later.

Next, the detailed configuration, structure, and operation of the Western-style toilet device 1 will be described.
1 to 4 are explanatory views of a Western-style toilet device 1 according to an embodiment. Note that FIGS. 2 (a) and 2 (b) are schematic side views schematically showing the inside of the Western-style toilet device 1 showing two modes of the cleaning method, all of which are the Western-style toilet device according to the present embodiment. It can be applied to 1.

The Western-style toilet device 1 is a sitting type toilet device fixed to a floor, a wall, or the like in a toilet space. The toilet body 10 of the Western-style toilet device 1 is decorated so that the bowl 12 opened upward is surrounded by the skirt portion 11, and the upper side of the bowl 12 is freely tiltable 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.

In the internal space of the skirt portion 11, a toilet bowl cleaning portion 13 that supplies cleaning 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 water supply to the bowl 12.

The drainage mechanism shown in FIG. 2A has a cylindrical 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 Western-style toilet device 1.

Further, in the figure, an example is shown in which the Western-style toilet 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, the Western-style toilet device 1 according to the present embodiment includes a cleaning end detecting means 19 for detecting the end of cleaning of the bowl 12 by the toilet bowl cleaning unit 13. The cleaning end detecting means 19 may be a sensor for detecting the end of water supply of the washing water, a control instruction, or the like, and the breaking level has been exceeded due to the water supply, although it depends on the definition of the cleaning end. It may be a sensor that detects. In the present embodiment, the cleaning end detecting means 19 is a sensor that detects that the stored water exceeds the rupture level.

Further, as described above and as shown in FIG. 1, the Western-style toilet device 1 includes a toilet lid open / close detection unit 21 and a toilet lid drive unit 22, and further receives an open / close instruction to the toilet lid drive unit 22. It is provided with a lid operation unit 23. Further, the Western-style toilet device 1 includes 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. It also has a seating detection unit 28.

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).

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 the Western-style 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, the toilet seat 24 first closes and then closes (stops in the closed state). Later, the toilet lid 20 performs a closing operation so as to be interlocked with the closing operation of the toilet seat 24. If both the toilet seat 24 and the toilet lid 20 are closed when the toilet seat 24 is instructed to open, the toilet lid 20 first opens, and after opening (stopping in the open state), the toilet lid 20. The toilet seat 24 opens the toilet seat 24 so as to be interlocked with the opening operation of the 20.

The Western-style toilet device 1 may further include 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 Western-style 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 a cleaning instruction to the toilet bowl cleaning unit 13 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 toilet 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. That is, when the 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 Western-style toilet device 1 controls the control target (water supply valve 16 of the toilet bowl 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 opening / closing. It includes a control unit 5 that receives output signals such as a detection unit 25 and a seating detection unit 28. The control unit 5 includes a processor such as a CPU and an MPU and various programs. The Western-style toilet device 1 further includes a power supply unit (not shown) and a timer (not shown).

Further, the Western-style toilet device 1 according to the present embodiment may include a notification unit composed of a speaker or the like that notifies an abnormality or state of the device or guidance by sound or voice synthesis. The notification unit 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 Western-style toilet device 1 will be described with reference to the flowcharts of FIGS. 3 and 4. All of these operations are operations by the control unit 5 when a cleaning instruction is given by the cleaning instruction means. The Western-style toilet device 1 may be set so that any of the operations shown in FIGS. 3 and 4 is executed when a cleaning instruction is given, or the operation may be changed so as to be executed. .. Further, if the cleaning operation unit 29 gives a cleaning instruction while the Western-style toilet device 1 is seated, the Western-style toilet device 1 does not accept the cleaning instruction.

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 of FIG. 3 will be described with reference to the flowcharts shown in steps S101 to S112. In the following description, the operation step of FIGS. 3 and 4 described as "step SXXX" is abbreviated as "SXXX".

If the toilet lid 20 is not in the open state (if it is in the closed state) when the cleaning instruction is received, the cleaning is started immediately after that, and the cleaning is waited for the end (N, S104, S105 of S101).

Here, various definitions are assumed for the end of cleaning. Specifically, the completion of the supply of the washing water into the bowl 12 may be the end of the washing, or the completion of the sealing water before that may be the end of the washing. In this embodiment, the latter is used.

The end of washing due to the end of supply of washing water is determined, for example, by closing the water supply valve 16 under the control of the control unit 5, stopping the water supply at the water supply port 14 (for example, detected by a flow meter or the like). In the case of the movable trap 17A, the cleaning may be completed when the trap 17A returns to the water sealing position. That is, the cleaning end detecting means 19 may be configured to detect at the control timing of the control unit 5, or may be configured to detect by the amount of water supplied at the water supply port 14.

In the case of the present embodiment, that is, in the case of the end of cleaning due to the securing of water sealing, the sealing water is cut off after the start of cleaning, and then water is accumulated in the bowl 12, but the accumulated water exceeds the breaking level. The cleaning end detecting means 19 may determine that the cleaning is completed. That is, in this case, the supply of the washing water is not finished, but the time when the sealing water is secured is judged to be the finishing of the washing. The fact that the stored water exceeds the rupture level may be determined by the water level measured by the cleaning end detecting means 19 such as a capacitance sensor or a radio wave sensor.

Further, the timing of the end of such cleaning can be determined by a timer. For example, if the breaking level of the stored water is exceeded, it may be 9 to 10 seconds after the start of washing, and if the cleaning is completed due to the end of supply of the washing water, it may be 15 to 20 seconds after the start of washing.

In the present embodiment, for example, as shown in S104 to S107 of FIG. 3, the stool lid 20 is opened after the washing is completed. Even if the toilet lid 20 is in the open state and the water is being supplied, it is sufficient that the contaminants do not scatter from the bowl 12 to the outside. Therefore, as in the present embodiment, it is sufficient to prevent the scattering of pollutants if it is determined that the timing of exceeding the rupture level of the stored water, in which the discharge of filth has already been completed, is the end of cleaning.

Then, after the cleaning is completed, whether the cleaning instruction is for stool or urine is determined by the stool cleaning button 29a and the urine cleaning button 29b of the cleaning operation unit 29 (S105Y, S106). If it is a cleaning instruction for stool, the stool lid 20 opens, and after a certain period of time after the stool lid 20 is opened, the stool lid 20 that has been opened closes, closes, and stands by (the stool lid 20). Is closed) (Y in S106, S107 to S109). Further, in the case of a cleaning instruction for urine, the toilet lid 20 ends without operating (N in S106).

Instead of the delay for a certain period of time, the standby state may be returned at the timing when the person is no longer detected by the motion sensor. Of course, since the user can close the toilet lid 20 with the toilet lid operation unit 23, it is not necessary to automatically return to the standby state.

In this way, in the case of a cleaning instruction for stool, the stool lid 20 is automatically opened and the open state continues for a certain period of time, so that the user can visually recognize the inside of the bowl 12 during that time and stool or paper. It is possible to discharge all the filth contained in it and check whether it has been properly washed.

In the case of a wash-off type or siphon type drainage mechanism, the filth may not be able to get over the upper part (highest part) in the trap 17, so visual inspection is often performed to check the remaining filth. The opening operation of the toilet lid 20 is extremely effective. Further, since the siphon type causes a siphon phenomenon, the suction force is large in the drainage direction, but in order to generate the siphon phenomenon, it is necessary to fill the inside of the trap 17 with water for a period of time. In order to fill the water with water, the diameter inside the trap 17 may be narrowed, the flow path may be complicated, or the flow may be temporarily impaired to allow the trap 17 to flow at once, which may cause clogging.

Further, in the case of a cleaning instruction for urine, since the amount of filth is small and the possibility of remaining after cleaning is low and it is generally discharged, a series of operations of opening and closing the toilet lid 20 (S107 to S109). It does not have to be removed, and the opening operation of the toilet lid 20 after cleaning can be omitted. When the cleaning button is of one type for stool and urine, it is sufficient to execute a series of operations (S107 to S109) for opening and closing the toilet lid 20 at the time of instructing cleaning.

Further, in the present embodiment, even if the toilet lid 20 is opened after cleaning, it is automatically closed (standby state) at the end, so that it is troublesome for the user to return to the standby state. There is no.

If the toilet lid 20 is in the open state and the toilet seat 24 is also in the open state when the cleaning instruction is received, the toilet seat 24 and the toilet lid 20 are sequentially closed, and cleaning is performed after the toilet lid 20 is closed (S101). Y, Y of S102, S110 to S112).

If there is a cleaning instruction with both the toilet lid 20 and the toilet seat 24 open in this way, it is determined that the cleaning instruction is a cleaning instruction at the time of standing urination of a boy. In the case of male urination, the possibility that filth remains is extremely low. Therefore, in this case as well, the series of operations of opening and closing the toilet lid 20 after the completion of washing may not be performed, and unnecessary operations can be omitted.

As described above, according to the operation of FIG. 3, after cleaning after defecation, the inside of the bowl 12 can be confirmed without opening the toilet lid 20. After the automatic opening of the toilet lid 20, the automatic closing operation is also performed after a delay for a certain period of time, so that the user can return to the standby state without any operation. As described above, since the toilet lid 20 is automatically opened and closed after cleaning, the user does not need to operate it with his / her fingers, which is hygienic.

Further, in the case of cleaning after urination, the toilet lid 20 is not opened after cleaning with the toilet lid 20 closed, but if the user wants to visually confirm, a manual opening operation is further required. If so, the closing operation should be performed after that, and there is no problem.

Further, according to the operation of FIG. 3, since the toilet lid 20 is closed for cleaning regardless of defecation or urination, there is almost no possibility that water or the like containing contaminants will be scattered outside the toilet bowl. Not hygienic. As described above, if it is determined that the cleaning is completed when the sealing level of the pooled water in the bowl 12 is exceeded at the time of water supply, it is possible to prevent the pollutants from scattering to the outside and save time. ..

Next, the operation of FIG. 4 will be described with reference to the flowcharts shown in S201 to S210.

If the toilet lid 20 is not in the open state (if it is in the closed state) when the cleaning instruction is received, the cleaning is started immediately after that and waits for the completion of the cleaning (N, S204, S205 of S201). Since the cleaning is completed in the same manner as in FIG. 3, the description thereof will be omitted.

After the cleaning is completed, the stool lid 20 opens, and after a certain period of time, the stool lid 20 once opened closes and closes to a standby state (S206 to S209).

That is, in the operation of FIG. 4, regardless of whether the cleaning instruction is for stool or the cleaning instruction for urine, after cleaning, the toilet lid 20 for confirmation in the bowl 12 is opened, and after a certain period of time. A series of operations including a closing operation for returning to the standby state of is executed.

Further, if the toilet lid 20 is in the open state and the toilet seat 24 is also in the open state when the cleaning instruction is received, that is, if the cleaning instruction is for male standing urination, the toilet seat 24 and the toilet lid 20 are sequentially closed. (Y of S201, Y of S202, S209, S210). Then, cleaning is started after the toilet lid 20 is closed, and after the cleaning is completed, a series of operations of opening and closing the toilet lid 20 are performed (S210, S205 to S208). In the case of male urination, since the filth does not contain paper and is only liquid, it is completed without performing a series of opening and closing operations of the stool lid 20 after cleaning with the stool lid 20 in the closed state as in FIG. You may.

As described above, according to the operation of FIG. 4, a series of opening and closing operations of the stool lid 20 are performed after the completion of washing regardless of whether the urination is defecation, sitting urination, or standing urination for men. That is, regardless of defecation or urination, the inside of the bowl 12 can be visually recognized after washing without hassle.

As described above, the opening operation of the toilet lid 20 after the completion of cleaning as illustrated in FIGS. 3 and 4 is an operation for the user to confirm the residual filth in the bowl 12. Since the opening operation of the toilet lid 20 is performed after the cleaning is completed, it is possible to prevent water and the like containing contaminants from being scattered from the inside of the bowl 12 to the outside when the toilet lid 20 is opened. However, since the cleaning is performed with the toilet lid 20 closed, there is a possibility that droplets may adhere to the back surface (inside) of the toilet lid 20, so that the toilet lid 20 is opened when the toilet lid 20 is opened immediately after cleaning. Moisture or the like adhering to the inside of the toilet lid 20 may jump out due to the impact of the operation.

Therefore, in order to avoid scattering of contaminants from the back surface of the toilet lid 20 to the outside in such an opening operation, the opening operation of the toilet lid 20 after the completion of cleaning is a normal opening operation, for example, a toilet lid operating unit. It is desirable that the rotation speed is slower than that of the operation of 23 or the automatic opening operation when entering the room. For example, if the normal opening operation of the toilet lid 20 is completed in about 3 seconds, it is conceivable that the time required for the opening operation of the toilet lid 20 after the completion of cleaning is 4 to 5 seconds. It is possible to make the rotation speed of the toilet lid 20 variable in this way by the toilet lid driving unit 22. It is desirable that such a slow opening operation of the toilet lid 20 after cleaning is also performed on the toilet seat device 30 (see FIG. 5) described later.

The operations of FIGS. 3 and 4 shown above are generally contradictory, and even if one of the operations can be selected by switching the setting of the Western-style toilet device 1, for example, based on the usage mode of the user. good.

The Western-style toilet device 1 may be one in which the toilet seat 24 and the toilet lid 20 are integrally replaceable. In particular, the Western-style toilet device 3 to which the toilet seat device 30 as shown in FIG. 5 is retrofitted (or replaced) may be used.
