Description

Toilet device and toilet seat device

Technical Field

The present invention relates to a toilet device and a toilet seat device that electrically open and close a toilet cover and a toilet seat independently.

Background

Recently, from the viewpoint of preventing the diffusion of pollutants contained in excrement discharged during flushing of a toilet (bowl), it is recommended to flush the bowl in a state where the toilet lid is closed after the excrement is discharged, so as to prevent the splash of pollutants contained in excrement discharged into the bowl from scattering to the outside of the toilet.

In order to reliably perform such a bowl flushing in a state where the toilet lid is closed, the following toilet apparatuses have been proposed: when a flush instruction is given, the toilet lid is electrically closed by the toilet lid driving unit, and then the bowl is flushed (see patent document 1, for example).

Problems to be solved by the invention

However, in such a toilet apparatus, when not only the toilet lid but also the toilet seat is opened when a flush instruction is given, the toilet seat is usually closed first and then the toilet lid is closed, and therefore, a long time is required from the flush instruction to the closing of the toilet lid. Patent document 1 describes that the toilet lid is closed when the toilet lid is in an open state and not seated, but does not describe that both the toilet lid and the toilet seat are in an open state.

In order to shorten the time, a method of simultaneously closing the toilet seat and the toilet lid may be considered. However, since the amount of electric power is increased at the drive (start of closing operation) timing and the closing timing of the toilet seat and the toilet lid, the amount of electric power is further increased at the timing when they are simultaneously started or closed, and there is a possibility that the electric power may adversely affect the machine (such as the motor).

The present invention has been made in view of the above circumstances, and an object thereof is to provide a toilet seat device and a toilet seat device that can avoid an increase in power while not requiring a long time until a toilet lid is closed in a closing operation of the toilet seat and the toilet lid when a flush instruction is issued.

Means for solving the problems

In order to achieve the above object, a toilet device according to the present invention includes: a pot body; a toilet flushing part for supplying flushing water to the basin body to flush the interior of the basin body; a toilet cover; a toilet lid opening/closing detection unit for detecting opening/closing of the toilet lid; a toilet seat; a flush instruction means for outputting a flush instruction to the toilet flush unit; and a control unit configured to electrically open and close the toilet lid and the toilet seat independently, wherein the toilet device is configured to: when the flushing indication mechanism indicates flushing, if the toilet cover is opened, the toilet cover is closed before the toilet flushing part flushes; on the other hand, if the toilet lid is closed, flushing by the toilet flushing unit is executed, and if the toilet lid and the toilet seat are open when the flushing instruction is received, the control unit starts the closing operation of the toilet lid after the closing operation of the toilet seat is started and before the toilet seat is closed.

The toilet seat device of the present invention includes: a toilet seat; a toilet cover; a toilet lid opening/closing detection unit for detecting opening/closing of the toilet lid; a bowl flushing indication mechanism for receiving a flushing indication for the toilet main body; and a toilet seat side control unit, the toilet seat device being attached to the toilet body, the toilet seat device being configured to electrically open and close the toilet cover and the toilet seat independently, the toilet seat device being configured to: when the flushing indication of the basin body flushing indication mechanism is available, if the toilet cover is opened, the toilet cover starts to close before the flushing indication is output to the toilet main body; on the other hand, if the toilet lid is closed, a flush instruction is output to the toilet main body, and if the toilet lid and the toilet seat are open when the flush instruction is received, the toilet seat side control unit starts the closing operation of the toilet lid after the closing operation of the toilet seat is started and before the toilet seat is closed.

Effects of the invention

Since the toilet seat device and the toilet seat device according to the present invention are configured as described above, it is possible to avoid an increase in power and to eliminate the need for a long time until the toilet cover is closed in the closing operation of the toilet seat and the toilet cover when a flush instruction is issued.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings. The toilet apparatuses 1 and 3 described below basically flush the bowl 12 in a closed state of the toilet lid 20 from the viewpoint of preventing the diffusion of pollutants contained in excrement. Therefore, if the toilet lids 20 and 40 are not closed when the flush instruction is given, the closing operation of the toilet lids 20 and 40 is automatically electrically performed as a normal operation before flushing in order to bring the toilet lids 20 and 40 into the closed state. Hereinafter, the closing operation of the toilet lids 20 and 40 and the subsequent flushing operation will be referred to as a sequence operation.

First, an outline of a basic configuration of the toilet apparatus 1 according to the present embodiment will be described below. The toilet apparatus 1 is an apparatus having the configuration illustrated in fig. 1 and 2, and executes the operation of the form illustrated in fig. 3 and 4.

The toilet device 1 includes: a bowl 12; a toilet bowl washing part 13 for supplying washing water to the bowl body 12 to wash the interior of the bowl body 12; a toilet cover 20; a toilet cover opening/closing detection unit 21 for detecting opening/closing of the toilet cover 20; and a toilet seat 24. The toilet apparatus 1 further includes a flush instruction unit that outputs a flush instruction to the toilet flush unit 13, and a control unit 5.

A structure in which the toilet lid 20 and the toilet seat 24 are electrically opened and closed independently; the structure is as follows: when a flushing instruction is given by the flushing instruction means, if the toilet lid 24 is opened, the toilet lid 20 starts to close before the toilet flushing unit 13 flushes; on the other hand, if the toilet lid 20 is closed, flushing by the toilet flushing unit 13 is performed.

When the flush instruction is received, if the toilet lid 20 and the toilet seat 24 are open, the control unit 5 executes a control operation of starting the closing operation of the toilet lid 20 after starting the closing operation of the toilet seat 24 and before closing the toilet seat 24.

Next, the detailed configuration, structure, and basic operation of the toilet apparatus 1 will be described.

Fig. 1 to 4 are explanatory views of the toilet apparatus 1. Fig. 2 (a) and (b) are schematic side views schematically showing the insides of two toilet apparatuses 1 having different flushing systems (structures), and either system may be used.

The toilet apparatus 1 is a western style toilet apparatus of a sitting type fixed to a floor, a wall, or the like in a toilet space. The toilet device 1 has a main body 10 in which a bowl 12 opened upward is installed, the bowl 12 is surrounded by a skirt 11, and a toilet seat 24 and a toilet lid 20 which are provided on the upper side of the bowl 12 so as to be able to stand up and down with respect to the opening surface of the bowl 12 and have the same rotation axis. Further, separate rotation shafts may be provided so as to be interlocked with each other.

A toilet flushing portion 13 for discharging sewage in the bowl 12 and supplying flush water from the 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 portion 11. The toilet flushing unit 13 includes a water supply mechanism and a water discharge mechanism.

The water supply mechanism is provided with: a water supply port 14; a washing water supply path 15 for supplying washing water supplied from a water supply 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 flush water supply passage 15 for supplying or blocking water to the bowl 12.

The drain mechanism shown in fig. 2 (a) has a tubular bent return (trap) 17 connected to extend rearward from the bottom of the bowl 12, and the bent return 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-sealed 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, a drainage mechanism that is neither siphon type nor movable type, for example, a straight flushing type drainage mechanism, may be applied to the toilet bowl apparatus 1.

In the drawings, an example is shown in which the toilet apparatus 1 is of a direct-connection-type water-free type with tap water without a flush tank (low-level tank), but may be of a configuration with a flush tank.

As shown in fig. 1, the toilet apparatus 1 includes, in addition to the toilet cover opening/closing detection unit 21, a toilet cover driving unit 22 and a toilet cover operating unit 23, and the toilet cover operating unit 23 receives an opening/closing instruction from a user with respect to the toilet cover driving unit 22. Further, the toilet apparatus 1 includes: a toilet seat 24; 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 to the toilet seat driving unit 26, and the toilet device 1 further includes a seating detection unit 28.

The toilet lid operation unit 23 and the toilet seat operation unit 27 may be constituted by switches that open and close independently, or may be alternately switched by 1 switch. In the latter case, it is sufficient to determine which instruction to open or close the toilet by the toilet lid opening/closing detection unit 21 (toilet seat opening/closing detection unit 25) in cooperation with software.

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. 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 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. The example shown in fig. 1 is a configuration in which the toilet lid 20 and the toilet seat 24 have driving units (motors), respectively, but may be a configuration in which 1 motor is driven individually.

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

In the toilet apparatus 1, when an instruction to close the toilet cover 20 is given by the toilet cover operating unit 23 or the like, if both the toilet cover 20 and the toilet seat 24 are in the open state, the toilet seat 24 is first closed, and then the toilet cover 20 is closed in conjunction with the closing of the toilet seat 24. The toilet apparatus 1 executes the above-described sequence operation when receiving the flush instruction, and executes the closing operation in order of the toilet seat 24 and the toilet cover 20 when the toilet seat 24 is opened at that time. The details of this operation will be described later with reference to fig. 3 and 4.

When an instruction to open the toilet seat 24 is given by the toilet seat operating unit 27 or the like, if both the toilet seat 24 and the toilet cover 20 are closed, the toilet cover 20 is first opened, and then the toilet seat 24 is opened in conjunction with the opening of the toilet cover 20.

The 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.

Further, the 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 for outputting a flush instruction to the toilet flush unit 13 via the control unit 5 described later.

The flushing operation unit 29 is preferably disposed in both the main body operation unit (not shown) and the remote controller (not shown). These devices are also provided with operation switches, operation buttons, and the like that enable various operations, settings, and the like. 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 means, and further, the change in state from sitting to unseating detected by the seating detection unit 28 also functions as a flushing instruction means. That is, when a person stands up from the toilet seat 24 while sitting, automatic flushing is performed instead of the operation of the flush button.

Note that both the stool flush button 29a and the urine flush button 29b may not be provided, and a flush instruction may be output by 1 flush button. That is, the amount of flush water to the bowl 12 in this case is only 1 type of large volume for feces, without distinction between large volume for feces and small volume for urine.

The 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 seat detection unit 28, and the like. The control unit 5 includes a processor such as a CPU or MPU and various programs. The toilet apparatus 1 further includes a timer unit 6 and a power supply unit (not shown).

The toilet device 1 further includes a notification unit 7, and the notification unit 7 is configured by a speaker or the like that notifies abnormality or state of the device or guidance by voice 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 audio output.

Next, the basic operation of the toilet apparatus 1 will be described based on the operation flowchart of fig. 3 and the schematic operation explanatory diagrams of the toilet seat 24 and the toilet lid 20 of fig. 4. This operation is performed by the control unit 5 when the flushing instruction is issued by the flushing instruction mechanism. For convenience of illustration, the schematic operation explanatory diagrams shown in fig. 4 (a) to (e) show the toilet seat 24 and the toilet cover 20 as different rotation axes (x in fig. 4), but they may be the same rotation axis as described above.

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 along the flowcharts shown in steps S100 to S110. In the following description, a portion described as "step sxxx" will be abbreviated as "sxxx" indicated by a symbol.

When a flushing instruction by the flushing instruction means is received, the notification unit 7 first notifies the user of the flushing instruction, for example, by an electronic sound "beep" (S100 and S101). Then, the open/close state of the toilet lid 20 is determined, and if the open/close state is determined, the bowl 12 is immediately flushed (no in S102, S109).

Although not shown in fig. 3, the toilet lid 20 may be opened after the flushing in S109 is completed, and after a certain time from the opening, the toilet lid 20 in the opened state may be closed and set to the standby state (the state in which the toilet lid 20 is closed).

The opening operation of the toilet lid 20 after the washing is performed to allow the user to confirm the remaining of the dirt in the bowl 12 after the washing. 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 state may be returned to the standby state at a timing (time) when the motion sensor no longer detects a human. 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, the open/close state of the toilet seat 24 is determined again (yes in S102, S103). If the toilet seat 24 is in the open state, the closing operation of the toilet seat 24 is started, and after a predetermined time has elapsed, the closing operation of the toilet cover 20 is started (yes in S103, S104 to S106 and (a) and (b) in fig. 4).

In this case, the toilet seat 24 and the toilet cover 20 may be moved as shown in fig. 4 (a) and (b), and the toilet cover 20 may be moved to close so as to follow the toilet seat 24 at an acute angle difference. The angular difference may be smaller than the angular difference between the upright position of the toilet lid 20 and the position immediately before the toilet seat 24 is closed, and the angular difference is preferably about 5 to 20 degrees in order to achieve rapid closing of the two. Of course, an angular difference of more than 20 degrees is also possible. In order to prevent the timing at which the toilet lid 20 starts to open and the timing at which the toilet seat 24 stops from overlapping, the upper limit of the angular difference is preferably about 70 degrees.

As in this example, such an angular difference may be provided based on the time delay by the timer unit 6, and the time delay may be calculated from the time taken from the standing state to the closing state of the toilet seat 24. For example, the delay time may be set to a time about 1/4 to 1/3 of the time taken from the standing state to the closing state.

Further, instead of such a time difference, the start timing of the closing operation of the toilet lid 20 may be measured based on the detection of the driving angle of the toilet seat 24.

The toilet seat 24 and the toilet lid 20 are separately kept closed as shown in fig. 4 (b) and (c), and the toilet seat 24 is first closed as shown in fig. 4 (d), and then the toilet lid 20 is closed as shown in fig. 4 (e).

When the toilet lid 20 is closed, the toilet lid 20 is reported to be closed by an electronic sound such as "beep" different from that at the time of the flush instruction, and the bowl 12 is flushed (S107 to S109). In addition, it is also possible to report not the closing of the toilet lid 20 but the fact that the flushing is performed. That is, in this case, the notification is also made when the toilet lid 20 is closed after the flushing instruction (no in S102).

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, it is determined whether the toilet is sitting or not, and if the toilet is not sitting, the closing operation of the toilet lid 20, the notification of closing, and the flush are executed (no in S110, S106 to S109). If it is seated, flushing is immediately started (Y of S110, S109).

As described above, the sequence operation is executed when the flush instruction is received when the toilet lid 20 is opened, but when the toilet seat 24 is also opened at this time, the toilet seat 24 and the toilet lid 20 sequentially execute the closing operation with the above-described angular difference.

Thus, the toilet cover 20 follows the toilet seat 24 at a predetermined angle, not the operation sequence of starting the closing operation of the toilet cover 20 while waiting for the toilet seat 24 to be closed. Therefore, the closing of the toilet lid 20 is performed quickly from the start of the closing operation of the toilet seat 24, and the flushing after the flushing instruction is performed quickly without waiting for a long time.

Further, since the closing operations of the toilet seat 24 and the toilet lid 20 are not performed simultaneously but are shifted by a time, the start timing of the closing operation does not overlap or the stop (closing) timing does not overlap, the electric power does not temporarily increase, and the possibility of a mechanical adverse effect is low.

Further, since the closing operation of the toilet lid 20 is started before the toilet seat 24 is closed as described above, the timing of starting the opening operation of the toilet lid 20 and stopping the toilet seat 24 do not overlap, and a temporary increase in the amount of electric power can be avoided.

When the toilet cover operation unit 23 performs the closing operation, the toilet cover 20 may start the closing operation after the toilet seat 24 is closed, but the operation may be performed with the same time difference as that when the flushing instruction is received as described above.

In addition, the opening operation by the toilet seat operating unit 27 may be performed in the order of starting the opening operation of the toilet seat 24 after the toilet cover 20 is completely opened, but may be performed in the order of opening the toilet cover 20 and the toilet seat 24 with a time difference. In this case, the angle difference may be about 5 to 20 degrees.

The toilet apparatus 1 is not limited to the above configuration, and may be configured such that the toilet seat 24 and the toilet lid 20 can be replaced as a single unit. In particular, the toilet seat device 30 shown in fig. 5 may be a toilet device 3 to which a rear portion is attached (or replaced). A basic configuration of a toilet bowl 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, the movable return trap 17A is illustrated in fig. 5 (b), but the present invention is also applicable to a configuration in which the toilet main body has a siphon-type return trap 17 (see fig. 2 (a)) or a configuration of another embodiment.

Specifically, the toilet device 3 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 seat device 30; a flush operation unit 29 for outputting a flush instruction to the toilet flush unit 13; a control unit (5); a timer unit 6 and a reporting unit 7.

The toilet seat device 30 is a separate body that can be attached to and detached from the toilet main body (a portion other than the toilet seat device 30) of the toilet device 3. The toilet seat device 30 includes: a toilet cover 40, a toilet cover opening/closing detection unit 41, a toilet cover driving unit 42, a toilet 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, a seating detection unit 48, a bowl flushing operation unit 49, a toilet seat side control unit 35, a timer unit 36, and a notification unit 37. The toilet seat device 30 can transmit and receive electric signals between toilet bodies.

The configuration of the toilet apparatus 3 (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 of fig. 1, and therefore, descriptions thereof are omitted.

The toilet seat device 30 of fig. 5 is configured to output a flushing instruction of the bowl 12 to the toilet flushing unit 13 from the toilet seat device 30 side. Specifically, in the toilet seat device 30, 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 control unit 5 on the toilet body side 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 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 flushing operation portion 29 on the toilet main body side. That is, fig. 6 shows a configuration in which the flush instruction can be given by either the flush operation unit 29 or the bowl flush operation unit 49. Note that the flush operation portion 29 may not be provided on the toilet main body side, and only the bowl flush operation portion 49 may be used to give a flush instruction. The bowl washing operation unit 49 preferably includes a stool washing button and a urine washing button.

The operation of the bowl washing operation portion 49 functions as a bowl washing instruction mechanism, but the state change from sitting to unseating detected by the seating detection portion 48 also functions as a bowl washing instruction mechanism. That is, when the toilet seat 44 is lifted up while sitting, automatic flushing is performed instead of the operation of the flush button.

The toilet device 3 can also perform the operations shown in fig. 3 and 4, as in the toilet device 1 of fig. 1. In short, when the flushing indication is given from the bowl flushing indication mechanism, the toilet flushing unit 13 basically flushes the bowl 12 in a state where the toilet cover 40 is closed. When both the toilet seat 44 and the toilet cover 40 are open when a flush instruction is issued, the toilet seat 44 and the toilet cover 40 are closed with an angular difference as shown in fig. 4, and the toilet cover 40 is closed and then flushed.

As described above, the toilet seat device 30 includes the toilet seat 44, the toilet cover 40, and the toilet cover opening/closing detection unit 41 that detects opening/closing of the toilet cover 40. The toilet seat device 30 is a device attached to a toilet body, and includes a bowl flushing instruction mechanism that receives a flushing instruction to the toilet body, and a toilet seat side control unit 35. The toilet seat device 30 is configured such that the toilet cover 40 and the toilet seat 44 are electrically opened and closed independently. Further, the toilet seat device 30 is configured as follows: when a flushing instruction is given by the bowl body flushing instruction mechanism, if the toilet cover 40 is opened, the toilet cover 40 starts to close before the flushing instruction is output to the toilet main body; on the other hand, if the toilet lid 40 is closed, a flush instruction is output to the toilet main body.

When the toilet seat side control unit 35 receives the flushing instruction, if the toilet cover 40 and the toilet seat 44 are open, the control operation of starting the closing operation of the toilet cover 40 after starting the closing operation of the toilet seat 44 and before closing the toilet seat 44 is executed. In this way, in the toilet apparatus 3, the toilet seat apparatus 30 cooperates with the toilet main body, so that the time-difference operation between the toilet cover 40 and the toilet seat 44 can be realized.

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, for example, or may be configured to include a toilet seat operating unit (not shown) that can perform various operations or settings (e.g., private parts washing device).
