Description

Western-style toilet device and toilet seat device

Technical Field

The present invention relates to a western-style toilet apparatus including a toilet cover and a toilet seat apparatus used by being attached to a western-style toilet main body.

Background

Recently, from the viewpoint of preventing the spreading of pollutants contained in human excrement during toilet flushing, it is recommended that excrement in the bowl be flushed away with the toilet lid closed when the excrement is discharged into the bowl of the western-style toilet device so that the spray containing pollutants is not scattered outside the toilet.

In order to reliably perform the bowl washing in the state where the toilet lid is closed, the following techniques are proposed: when a flush instruction is given by a flush instruction mechanism such as a flush operation unit, the toilet lid is automatically closed electrically, and then the toilet is flushed (see, for example, patent document 1). The technique of patent document 1 performs a closing operation as long as the seat is not seated.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, a basic configuration of the western-style toilet apparatus 1 according to the present embodiment will be described.

The western-style toilet apparatus 1 includes: a bowl body 12; a toilet flushing part 13 for supplying flushing water to the bowl body 12 to flush the interior of the bowl body 12; a toilet cover 20; a toilet lid opening/closing detection unit 21 for detecting opening/closing of the toilet lid 20; and a toilet lid driving unit 22 for opening and closing the toilet lid 20. The western-style toilet apparatus 1 further includes: a flush instruction unit for outputting a flush instruction to the toilet flush unit 13; and a control unit 5. The western-style toilet apparatus 1 is configured to start flushing by the toilet flushing unit 13 when a flushing instruction is issued from the flushing instruction mechanism and then the toilet lid opening/closing detection unit 21 determines that the toilet lid 20 is in the closed state.

When the flush instruction is issued from the flush instruction mechanism, the control unit 5 controls the toilet lid driving unit 22 to start the closing operation of the toilet lid 20 when the toilet lid opening/closing detection unit 21 determines that the toilet lid 20 is in the open state. When a toilet lid closing cancel command is issued during the closing operation of the toilet lid 20, the control unit 5 controls the toilet lid driving unit 22 to stop the closing operation of the toilet lid 20. The details of the "toilet lid closing cancellation command" will be described later.

Next, the detailed structure, and operation of the western-style toilet apparatus 1 will be described.

Fig. 1 to 4 are explanatory views of a western-style toilet apparatus 1 according to an embodiment. Fig. 2 (a) and (b) are schematic side views schematically showing the inside of the western-style toilet apparatus 1 in two forms of the flushing system, and both of them can be applied to the western-style toilet apparatus 1 according to the present embodiment.

The western-style toilet apparatus 1 is a toilet apparatus fixed to a floor, a wall, or the like in a toilet space. The western-style toilet device 1 includes a bowl body 12 opened upward in a toilet body 10, a skirt portion 11 surrounding the bowl body 12, and a toilet seat 24 and a toilet lid 20 provided on an upper side of the bowl body 12 to be raised and lowered with respect to an opening surface of the bowl body 12 and having the same rotation axis.

A toilet flushing part 13 for supplying flush water from a water supply port 14 into the bowl 12 to flush the interior of the bowl 12 is disposed in the inner space of the skirt part 11. The toilet flushing unit 13 includes a water supply mechanism and a water discharge mechanism.

The water supply mechanism comprises: a water supply port 14; a washing water supply path 15 for supplying washing water supplied from a water pipe (not shown) into the 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 for supplying or cutting off the water supply to the bowl 12.

The drain mechanism shown in fig. 2 (a) has a cylindrical curved return bend (trap) 17 connected to extend rearward from the bottom of the bowl 12, and the return bend 17 extends further downward and is connected to the drain 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-sealed state by a siphon action.

Further, the drain mechanism may have a movable return trap 17A as shown in fig. 2 (b). The return trap 17A is rotated in the direction of the arrow by a driving unit (not shown) to be in a drainage state or a water-sealing state. The return trap 17A is illustrated in a position in a water-sealed state, and in a water-discharging state, the open end of the return trap 17A is rotated so as to be directed toward the water discharge port 18. The return trap 17A is surrounded by a return trap case (not shown) so that sewage or odor does not leak to the outside.

Further, in the western-style toilet apparatus 1, a drainage mechanism which is neither a siphon type nor a movable type, for example, a direct flushing type drainage mechanism can be applied.

In the drawings, the western-style toilet apparatus 1 is shown as a direct-connection-type water-tank-free type toilet apparatus having no flush tank (low-level tank).

The western-style toilet apparatus 1 according to the present embodiment includes a flush completion detection mechanism 19, and the flush completion detection mechanism 19 detects completion of flushing of the bowl body 12 by the toilet flushing unit 13. The flush end detection means 19 may be defined by a sensor for detecting the end of the supply of flush water based on the end of flushing, a sensor for detecting that the level of the accumulated water exceeds the burst level due to the supply of flush water based on a control instruction, or the like. In the present embodiment, the flush completion detection means 19 is a sensor for detecting that the accumulated water exceeds the seal-breaking level.

As described above, the western-style toilet apparatus 1 further includes the toilet lid opening/closing detection unit 21, the toilet lid driving unit 22, and the toilet lid operation unit 23 as shown in fig. 1, and the toilet lid operation unit 23 receives an opening/closing instruction to the toilet lid driving unit 22. Furthermore, the western-style toilet apparatus 1 includes: a toilet seat opening/closing detection unit 25 for detecting opening/closing of the toilet seat 24; a toilet seat driving unit 26 for opening and closing the toilet seat 24; and a toilet seat operating unit 27 that receives an opening/closing instruction for the toilet seat driving unit 26, and the western-style toilet apparatus 1 further includes 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/unseating, an infrared sensor for detecting seating/unseating from the vicinity of the rotation shaft of the toilet seat 24, or the like is used. As the toilet lid opening/closing detection unit 21 and the toilet seat opening/closing detection unit 25, a detection unit configured to detect an open/closed state based on an opening angle is used.

The toilet lid driving unit 22 and the toilet seat driving unit 26 are each constituted by a motor or the like. The toilet cover driving unit 22 electrically opens and closes (raises and lowers) the toilet cover 20 when instructed by the toilet cover operating unit 23, and the toilet seat driving unit 26 electrically opens and closes (raises and lowers) the toilet seat 24 when instructed by the toilet seat operating unit 27.

In the present specification, a state in which the toilet lid 20 and the toilet seat 24 stand substantially vertically is referred to as an open state, and a state in which the toilet lid is laid substantially horizontally and is substantially parallel to the opening surface of the bowl 12 is referred to as a closed state.

In the western-style toilet apparatus 1, when an instruction to close the toilet cover 20 is given, if both the toilet cover 20 and the toilet seat 24 are in the open state, the toilet seat 24 is first closed, and after closing (stopping in the closed state), the toilet cover 20 is closed in conjunction with the closing of the toilet seat 24. When an instruction is given to open the toilet seat 24, if both the toilet seat 24 and the toilet lid 20 are closed, the toilet lid 20 is first opened, and after the opening is stopped (stopped in the opened state), the toilet seat 24 is opened in conjunction with the opening of the toilet lid 20.

The western-style toilet apparatus 1 may further include various functional devices such as a deodorizing device for deodorizing the interior of the bowl 12, a heating device for heating the toilet seat 24, and a local flushing device for flushing a local area.

Furthermore, the western-style toilet apparatus 1 includes a flush operation unit 29. The flush operation unit 29 includes a stool flush button 29a and a urine flush button 29b that output a flush instruction to the stool flush unit 13 via the control unit 5 described later.

It is preferable that the flushing operation unit 29 is disposed in both the main body operation unit (not shown) and the remote controller (not shown). An operation switch, an operation button, and the like capable of performing various operations, settings, and the like are also provided thereon. The remote controller is preferably configured to use infrared communication. Of course, the remote controller is provided with a transmission unit (not shown), and the toilet body 10 is provided with a reception unit (not shown).

The operation of the flushing operation unit 29 functions as a flushing instruction method, and further, the change from the seated state to the unseated state detected by the seating detection unit 28 also functions as a flushing instruction method. That is, when standing from the toilet seat 24 while sitting, automatic flushing is performed instead of the operation of the flush button.

Alternatively, both the stool flush button 29a and the urine flush button 29b may be omitted, and the flush instruction may be output by 1 flush button. That is, the amount of flush water to the bowl 12 in this case is 1 type of large volume for feces, without distinction between large volume for feces and small volume for urine.

The western-style toilet apparatus 1 includes a control unit 5, and the control unit 5 controls the control targets (the water supply valve 16 of the toilet flushing unit 13, the toilet cover driving unit 22, the toilet seat driving unit 26, and the like) and receives output signals of the flushing operation unit 29, the toilet cover 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 or MPU and various programs. The western-style toilet apparatus 1 further includes a power supply unit (not shown) and a timer (not shown).

The western-style toilet apparatus 1 according to the present embodiment may include a notification unit configured by a speaker or the like for notifying abnormality, state, and presentation information of the apparatus by voice 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 audio output.

Next, the basic operation of the western-style toilet apparatus 1 will be described based on the flowcharts of fig. 3 and 4. These operations are all operations performed by the control unit 5 when the flushing instruction mechanism issues a flushing instruction. The western-style toilet apparatus 1 may execute any one of the operations shown in fig. 3 and 4 when a flush instruction is given, or may execute any one of the operations by changing the setting. In addition, when the flush operation unit 29 issues a flush instruction while seated, the western-style toilet apparatus 1 does not receive the flush instruction.

In the following description of the operation, 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 the respective detection units, but the description of the operation of these detection units is omitted. The opening and closing operation of the toilet lid 20 and the opening and closing operation of 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 the flowcharts shown in steps S101 to S118. In the following description, the operation steps shown in fig. 3 and 4 will be simply referred to as "step sxxx".

Upon receiving the flushing instruction, if the toilet lid 20 is not in the open state (if in the closed state), flushing of the bowl 12 is performed immediately thereafter (no in S101, S109). After the completion of flushing, the toilet lid 20 is opened, and after a certain time from the opening, the toilet lid 20 in the opened state is closed and brought into a standby state (a state in which the toilet lid 20 is closed) (S110 to S112).

The opening operation of the toilet lid 20 after the washing is performed to confirm the remaining of the dirt in the bowl 12 after the washing by the user. That is, the user does not need to manually open the toilet lid 20 after flushing in order to confirm the interior of the bowl 12.

Instead of the delay of the fixed time, the human body sensor may return to the standby state at a time (timing) when the human body sensor no longer detects a human body. Of course, the user can close the toilet lid 20 by the toilet lid operating unit 23, and thus the toilet lid does not have to automatically return to the standby state.

When the flush instruction is received, if the toilet lid 20 is in the open state and the toilet seat 24 is also in the open state, the closing operation of the toilet seat 24 is first started (yes in S101, yes in S102, S103). If a toilet seat closing cancellation command (abbreviated as "toilet seat cancellation" in the figure) is issued during this closing operation (until the toilet seat 24 is closed), the closing operation of the toilet seat 24 is stopped in the middle (S104, no in S105, yes in S104, S113). Subsequently, the toilet seat 24 that has been temporarily stopped starts the opening operation and is in the open state (S114).

The toilet seat closing cancellation command is a stop command to the toilet seat 24 that the control unit 5 receives when a force in the opposite direction to the torque in the closing direction of the toilet seat 24 is applied by stopping the closing operation of the toilet seat 24 with a finger or the like or when an opening instruction is issued by the toilet seat operating unit 27. The action of a force in the direction opposite to the torque in the closing direction of the toilet seat 24 due to the braking behavior can be detected by the toilet seat opening/closing detection unit 25, or can be detected by another sensor provided on the shaft of the toilet seat 24.

Thus, the toilet seat 24 is finally opened by the toilet seat closing cancel command. Next, the flush instruction is cancelled (invalidated) (S115). That is, when defecation and urination are completed and a flushing instruction is received, flushing is not started but is stopped according to the user's will.

If there is no toilet seat closing cancel command during the closing operation until the toilet seat 24 is closed, the closing operation of the toilet cover 20 is started (no in S104, yes in S105, and S106). If a toilet lid closing cancel command (abbreviated as "toilet lid cancel" in the drawing) is issued during the closing operation (until the toilet lid 20 is closed), the closing operation of the toilet lid 20 is stopped in the middle (S107, no in S108, yes in S107, S116). The toilet lid 20 that has been temporarily stopped starts the opening operation and is in the open state (S117).

The toilet lid closing cancel command is a stop command to the toilet lid 20 that the control unit 5 receives when a force in the direction opposite to the torque in the closing direction of the toilet lid 20 is applied by stopping the closing operation of the toilet lid 20 with a finger or the like or when an open command is issued by the toilet lid operating unit 23. The force acting in the direction opposite to the torque in the closing direction of the toilet lid 20 due to the restraining action can be detected by the toilet lid opening/closing detection unit 21, or can be detected by another sensor provided on the shaft. The toilet seat opening command may include an opening command of the toilet seat operating unit 27.

Thus, the toilet lid 20 is finally opened by the toilet lid closing cancel command. Subsequently, the flush instruction is canceled (invalidated) (S118). That is, although the user gives a flushing instruction after defecation or urination is completed, the flushing is stopped without starting the flushing according to the user's intention.

When the flush instruction is received, if the toilet lid 20 is in the open state and the toilet seat 24 is in the closed state, the closing operation of the toilet lid 20 is started (yes in S101, no in S102, S106). If a toilet lid closing cancellation command (abbreviated as "toilet lid cancellation" in the figure) is issued during the closing operation (until the toilet lid 20 is closed), the closing operation of the toilet lid 20 is stopped (S107, no in S108, yes in S107, S116). The toilet lid 20 temporarily stopped starts the opening operation and is set to the open state (S118). Next, the flushing instruction is cancelled (S118).

If there is no toilet lid closing cancel command during the closing operation of the toilet lid 20, flushing is performed (no in S107, yes in S108, S109). After the completion of flushing, the toilet lid 20 is opened, and after a certain time, the toilet lid 20 which has once been in the opened state is closed and brought into a standby state (S110 to S112).

As described above, the western-style toilet apparatus 1 starts flushing by waiting for the toilet lid 20 to be closed if a flushing instruction is given (immediately after closing if the toilet lid 20 is in the closed state, and after closing if the toilet lid 20 is in the open state). However, when a cancel command is issued during the closing operation of the toilet seat 24 or the toilet lid 20, the toilet seat 24 or the toilet lid 20 is opened, and the flushing is canceled without starting the flushing.

Thus, even if a flushing instruction is given, the flushing can be cancelled (the flushing instruction is invalidated) at the will of the user. Further, the user can visually check the state of the excrement and urine from above in the bowl 12 in which the toilet cover 20 or the toilet seat 24 is opened. After the toilet seat 24 or the toilet lid 20 is stopped (S113, S116), the toilet seat may be opened not automatically, but the interior of the bowl 12 may be visually checked in a conventional state or in a state where the user manually opens the toilet seat or the toilet lid.

When the user wants to perform flushing after flushing is disabled, the user can give a flushing instruction again by operating the flushing operation unit 29. In addition, the user may close the toilet lid 20 to flush the bowl 12 without giving a cancel command during the closing operation of the toilet seat 24 and the toilet lid 20.

The western-style toilet apparatus 1 includes a toilet seat opening/closing detection unit 25, a toilet seat driving unit 26, and a toilet seat operation unit 27 related to the toilet seat 24, but may not have these. In this case, it is sufficient if only the open/close state of the toilet lid 20 is detected when a flushing instruction is given, and if the open state is detected, the closing operation of the toilet lid 20 is started, and if the closed state is detected, flushing is performed. That is, in the flowchart of fig. 3, a series of operations not including S102 to S105 and S113 to S115 is executed.

Next, the operation of fig. 4 will be described. In the operation in this figure, S201 to S212 are the same as S101 to S112 in fig. 3, and therefore, their description is omitted. On the other hand, the operation when the toilet seat closing cancellation command and the toilet lid closing cancellation command are issued is different from that in fig. 3, and therefore only the operation will be described.

When the toilet seat closing cancellation command is issued, the toilet seat 24 is turned to the open state by stopping the operation (yes in S204, S213, S214). The toilet seat 24 is flushed in the opened state, and after a predetermined time from the end of flushing, the toilet seat 24 is closed and then the toilet lid 20 is also closed (S215 to S218).

When a toilet lid closing cancel command is issued, the toilet lid 20 is stopped, turned to an open operation, and opened (yes in S207, S219, S220). The toilet lid 20 is flushed in the opened state, and after a predetermined time from the end of flushing, the toilet lid 20 is closed (S221 to S223).

In summary, the operation of fig. 4 is contrary to the principle of flushing in the state where the toilet lid 20 is closed, and flushing in the state where the interior of the bowl 12 is exposed is exceptionally performed. For example, in the case where the closed state of the toilet lid 20 is not an essential condition during flushing, as in the case of urination, the flushing in the open state of the toilet lid 20 may be performed according to the will of the user. The toilet seat 24 and the toilet lid 20 may be not opened but may be stopped for flushing.

The flushing instruction for stool and the flushing instruction for urine may be received by distinguishing the flushing button 29a for stool and the flushing button 29b for urine, and the operation of fig. 3 may be executed in the case of flushing for stool and the operation of fig. 4 may be executed in the case of flushing for urine.

The operation mode when the flushing instruction is given is not limited to the operation of fig. 3 or 4. For example, a delay time for the user to confirm the inside of the bowl 12 may be provided before the flushing in steps S215 and S221 in fig. 4, and the closing operation of the toilet lid 20 may be further performed thereafter. If the toilet lid 20 is closed at this point (timing), flushing in the closed state of the toilet lid 20 can be performed as a rule. Further, an operation of not returning to the standby state after flushing may be performed.

In fig. 3 and 4, the toilet lid 20 after completion of flushing may be opened in a state where moisture or the like containing contaminants is not scattered from the viewpoint of preventing diffusion of contaminants. Therefore, the detection of the completion of flushing by the flushing completion detection means 19 may be configured not to be determined by the stop of the water supply valve 16 or the completion of water supply from the water supply port 14, but in the western-style toilet apparatus 1, the flushing completion detection means 19 (sensor) detects the time (timing) when the accumulated water exceeds the seal-breaking level during flushing.

As described above, the operation of the western-style toilet apparatus 1 may be various operations as long as at least the operation in which the toilet lid 20 is stopped by the toilet lid closing cancel command and the toilet seat 24 is stopped by the toilet seat closing cancel command is executed.

The western-style toilet apparatus 1 may be configured such that the toilet seat 24 and the toilet cover 20 can be replaced as one body. In particular, as shown in fig. 5, a western-style toilet apparatus 3 in which the toilet seat apparatus 30 is mounted (or replaced) at the rear may be used. A basic configuration of a western-style toilet apparatus 3 according to another embodiment of the present invention will be described with reference to fig. 5 (a) and (b). In the present embodiment, although the western-style toilet main body is illustrated as a siphon-type structure in fig. 5 (b), the present invention is also applicable to a structure having a movable return trap 17A (see fig. 2 (b)) or other structures.

Specifically, the western-style toilet apparatus 3 includes a bowl 12, a toilet flushing unit 13 for supplying flush water to the bowl 12 to flush the interior of the bowl 12, a toilet seat device 30, and a flush operation unit 29 for outputting a flush instruction to the toilet flushing unit 13.

The toilet seat device 30 is detachably provided to the main body of the western-style toilet apparatus 3 (a portion other than the toilet seat device 30). The toilet seat device 30 includes a toilet seat cover 40, a toilet seat cover opening/closing detection unit 41, a toilet seat cover driving unit 42, a toilet seat cover 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, and a seating detection unit 48.

Note that the configuration of the western-style toilet apparatus 3 (western-style toilet main body) other than the toilet seat apparatus 30 is substantially the same as that of fig. 1, and therefore, a detailed description thereof is omitted. Note that the toilet cover 40, the toilet cover opening/closing detection unit 41, the toilet cover driving unit 42, the toilet cover operating unit 43, the toilet seat 44, the toilet seat opening/closing detection unit 45, the toilet seat driving unit 46, the toilet seat operating unit 47, and the seating detection unit 48 included in the toilet seat device 30 are also substantially the same as those in fig. 1, and therefore, the description thereof is omitted.

The western-style toilet apparatus 3 shown in fig. 5 is further provided with a bowl washing operation unit 49, and can output a washing instruction of the bowl 12 to the toilet washing unit 13 from the toilet seat apparatus 30 side. Specifically, the toilet seat device 30 includes the toilet seat side control unit 35, and when an instruction to flush is issued from the bowl flushing operation unit 49, the toilet seat side control unit 35 receives the instruction, and can control the toilet flushing unit 13 via the main body side control unit 5 to flush the bowl 12. Further, the toilet seat side control unit 35 may directly control the toilet flushing unit 13.

As shown in fig. 5, the western-style toilet apparatus 3 may be configured to include not only the bowl flushing operation portion 49 on the toilet seat apparatus 30 side but also the main body flushing operation portion 29. That is, the configuration of fig. 5 is a configuration in which the flushing instruction can be given by either the flushing operation portion 29 or the bowl flushing operation portion 49. Further, the main body side may not be provided with the flush operation portion 29, and the flush instruction may be given only by the bowl flush operation portion 49. Further, it is preferable that the bowl washing operation part 49 also has a stool washing button and a urine washing button.

The western-style toilet apparatus 3 can also perform the operations shown in fig. 3 and 4, as in the western-style toilet apparatus 1 shown in fig. 1.

In short, when a flush instruction is issued from the bowl flushing operation portion 49, the toilet flushing portion 13 basically flushes the bowl 12 in a state where the toilet cover 40 is closed. Then, the toilet cover 40 is stopped by the toilet cover cancel command, and the toilet seat 44 is stopped by the toilet seat cancel command.

As described above, the toilet seat device 30 includes the toilet seat 44, the toilet cover 40, the toilet cover opening/closing detection unit 41 that detects opening/closing of the toilet cover 40, and the toilet cover drive unit 42 that opens/closes the toilet cover 40. The toilet seat device 30 is a device attached to the western-style toilet main body, and includes a bowl flushing operation unit 49 for receiving a flushing instruction to the western-style toilet main body, and a toilet seat side control unit 35. When the toilet seat device 30 issues a flush instruction from the bowl flush operation unit 49, the toilet cover opening/closing detection unit 41 then determines that the toilet cover 40 is in the closed state, and outputs the flush instruction to the western-style toilet main body.

When a flush instruction is issued from the bowl flushing operation unit 49, the toilet seat side control unit 35 controls the toilet cover driving unit 42 to start the closing operation of the toilet cover 40 when the toilet cover opening/closing detection unit 41 determines that the toilet cover 40 is in the open state. When a toilet lid closing cancel command is issued during the closing operation of the toilet lid 40, the toilet seat side control unit 35 controls the toilet lid driving unit 42 to stop the closing operation of the toilet lid 40.

The toilet seat device 30 according to the present embodiment further includes a toilet seat opening/closing detection unit 45, a toilet seat driving unit 46, and a toilet seat operating unit 47, and can stop the toilet seat 44 in the closing operation by a toilet seat closing cancellation command, as in the configuration of fig. 1.

Note that, even when the toilet seat device 30 receives a flush instruction from the flush operation unit 29 of the western-style toilet main body, the same operation as the operation of the flush instruction by the bowl flush operation unit 49 may be performed.

The toilet seat device 30 is not limited to the configuration shown in fig. 5. The toilet seat device 30 may be configured to include a private parts washing device and a toilet seat side notification unit, for example, or may be configured to include a toilet seat side operation unit that enables various operations and settings (for example, private parts washing device).
