The supply of water to the vat 12.

Next, the detailed configuration, structure, and operation of the Western-style toilet device 1 will be described based on FIGS. 1 to 6 . Fig. 1(a) is a basic block diagram showing the internal structure of a Western-style toilet device 1 according to an embodiment of the present invention, Fig. 1(b) is a side view of the Western-style toilet device 1, and Fig. 2 is a longitudinal section of the Western-style toilet device 1 picture. 3( a ) to FIG. 3( d ) are diagrams showing states of the toilet lid 20 corresponding to four examples of timings of start of washing from the closing operation of the toilet lid 20 to its complete closing. 4 to 6 are flowcharts showing three examples of basic operations of the Western-style toilet device 1 .

First, the configuration and structure of the Western-style toilet device 1 will be described based on FIG. 1( a ), FIG. 1( b ) and FIG. 2 .

The western-style toilet device 1 is a seated toilet device fixed on the floor or wall in the toilet space. The toilet body 10 of this Western-style toilet device 1 is installed with a barrel 12 opening upwards to surround the skirt 11; on the upper side of the barrel 12, there is a The toilet seat 24 and the toilet lid 20 are under the cover and have the same rotation axis 8 with each other.

The toilet seat 24 is a ring-shaped seat portion having an opening 24a in the center, and when placed on the top surface of the lip portion 12a of the bowl 12 via a cushioning member 24c (closed state), it becomes parallel to the floor surface and becomes seatable. .

In addition, the toilet lid 20 includes a top surface portion 20a and a peripheral wall surface portion 20b hanging down from the edge of the top surface portion 20a, and has a shape covering the toilet seat 24 when the toilet lid 20 is closed. When the toilet lid 20 is closed, the opening 24a of the toilet seat 24 is closed, that is, the opening of the bowl 12 is closed. In addition, in the example of this embodiment, as shown in FIG. 2, in the closed state of the toilet lid 20, when viewed from the side, the entire side of the toilet seat 24 is hidden.

A toilet cleaning part 13 is disposed in the inner space of the skirt part 11 , and supplies cleaning water into the bowl 12 from the water supply port 14 to clean the inside of the bowl 12 . The toilet cleaning unit 13 is provided with a water supply mechanism and a drainage mechanism.

The water supply mechanism includes: a water supply port 14; a cleansing water supply path 15 for supplying cleansing water supplied from a tap water pipe (not shown) into the tub 12 through the water supply port 14; and a water supply valve 16 arranged in the cleansing water supply On the way of the road 15, the water supply to the tank 12 is supplied or cut off.

In addition, the drainage mechanism has a structure including a movable water trap 17 in this embodiment. The water trap 17 is rotated between a water sealing state and a draining state (a state shown by a dotted line) by a driving unit (not shown). The water trap 17 in the legend is located at the water sealing state, and in the drainage state, the open end of the water trap 17 is located at the position facing the drain outlet 18 . In addition, the water trap 17 is surrounded by the water trap shell 19, so that sewage and odor do not leak to the outside.

In addition, a siphon type, a siphon jet type, a siphon vortex type, a flush type, and other drainage mechanisms may also be applied to the western-style toilet device 1 .

In addition, in the illustration, the Western-style toilet device 1 is shown as an example of a water pipe direct connection type without a water tank (low tank), but it may also be configured to have a water tank.

In addition, the western-style toilet device 1 includes a toilet lid opening and closing detection unit 21 and a toilet lid driving unit 22 as described above, and further includes a toilet lid operating unit 23 that receives an opening and closing instruction for the toilet lid driving unit 22 . Further, the Western-style toilet device 1 includes a toilet seat opening and closing detection unit 25 for detecting the opening and closing of the toilet seat 24, a toilet seat driving unit 26 for opening and closing the toilet seat 24, and a toilet seat for receiving an opening and closing instruction for the toilet seat driving unit 26. An operation unit 27 and a seat detection unit 28 .

As the seating detection unit 28, for example, a load sensor installed in the toilet seat 24 to detect sitting/leaving, or an infrared sensor to detect sitting/leaving from the vicinity of the rotating shaft 8, etc. are used. The toilet lid opening/closing detection section 21 and the toilet seat opening/closing detection section 25 are configured to be able to detect the open/closed state and detect the tilt angle during operation.

The toilet lid drive unit 22 and the toilet seat drive unit 26 are each constituted by a motor or the like. When there is an instruction from the toilet lid operating part 23, etc., the toilet lid driving part 22 opens and closes the toilet lid 20 in an electric manner (make it lift off the cover); when there is an instruction from the toilet seat operating part 27, etc., The toilet seat driving part 26 opens and closes the toilet seat 24 in an electric manner (make it lift off the cover). In addition, these driving parts operate by changing the driving force (closing operation speed, torque) to strongly push the toilet lid 20 and the toilet seat 24 immediately before the toilet lid 20 and the toilet seat 24 are completely closed.

In addition, in this specification, in any one of the toilet lid 20 and the toilet seat 24, the state of erecting approximately vertically is called the open state, and the state of approximately horizontally covering the opening of the bowl 12 is the open state. The roughly parallel state is called the off state.

In this western-style toilet device 1, when there is an indication of the closing action of the toilet lid 20, if the toilet lid 20 and the toilet seat 24 are both in the open state, at first, the toilet seat 24 is made to perform the closing action, and when it is completely closed (stops in the closed state) ), the toilet lid 20 is closed in a manner linked to the closing movement of the toilet seat 24 . In addition, when there is an instruction to open the toilet seat 24, if both the toilet seat 24 and the toilet lid 20 are in the closed state, firstly, the toilet lid 20 is opened, and after it is fully opened (stopped in the open state), it is connected with The opening action of the toilet lid 20 is linked to make the toilet seat 24 open.

Furthermore, the Western-style toilet device 1 is provided with a cleaning operation unit 29 . The cleaning operation unit 29 is provided with a cleaning button 29a for stool and a cleaning button 29b for urination, which output cleaning instructions to the toilet cleaning unit 13 through the control unit 5 described later.

In addition, the cleaning operation part 29 is preferably configured with both the main body operation part (not shown) and the remote controller (not shown). There are also provided operation switches, operation buttons, and the like for performing various operations and settings. As a remote control, it is suitable for those who use infrared communication. Naturally, a transmitter (not shown) is provided on the remote controller, and a receiver (not shown) is provided on the toilet body 10 .

The operation of the cleaning operation part 29 acts as a cleaning instruction means; furthermore, the state transition from sitting to leaving a seat detected by the seat detection part 28 can also be used as a cleaning instruction means. That is, when standing up from the toilet seat 24 when sitting down, automatic cleaning is performed instead of the operation of the cleaning button.

In addition, both the toilet cleaning button 29a and the urine cleaning button 29b are not provided, and a cleaning instruction is output by one cleaning button. That is to say, in this case, there is no difference between the large capacity for stool and the small capacity for urine in the amount of washing water to the bowl 12, and there is only a large capacity for stool.

The Western-style toilet device 1 has a control unit 5 that controls the control object (the water supply valve 16 of the toilet cleaning unit 13, the toilet lid driving unit 22, the toilet seat driving unit 26, etc.), and on the other hand, the cleaning operation unit 29 Or the output signal of the toilet lid opening and closing detection unit 21, the toilet seat opening and closing detection unit 25, the seat detection unit 28, and the like. The control unit 5 includes processors such as CPU and MPU and various programs. The western-style toilet device 1 further includes a timing unit 6 and a power supply unit (not shown).

In addition, the Western-style toilet device 1 of the present embodiment is equipped with a notification unit 7, which is composed of a speaker for notifying abnormality or status of the device, guidance, etc. by voice or speech synthesis. In addition, as the notification part 7, instead of an audio output device, or a configuration including a display such as an LED may be used in addition thereto.

The western-style toilet device 1 can also be further equipped with various functional devices such as a deodorizing device for deodorizing the bowl 12, a heating device for heating the toilet seat 24, and a local cleaning device for partial cleaning.

As mentioned above, the Western-style toilet device 1 is configured as follows: When there is a washing instruction, if the toilet lid 20 is in the open state, the closing operation of the toilet lid 20 is started, and thereafter, the washing water is started until it is completely closed. The supply to barrel 12. In short, the timing of starting the cleaning may be after the closing action of the toilet lid 20 starts.

Considering the balance between preventing the spray from cleaning from spreading to the outside of the bowl 12 and cleaning as soon as possible after the cleaning instruction, for example, the inclination angle θ between the toilet lid 20 and the closed toilet seat 24 should be approximately Start cleaning after 30 degrees (refer to Figure 1(b)). From the viewpoint of preventing the spread of droplets, it is preferable to make the angle of about 30 degrees the upper limit value for allowing cleaning to start.

In this way, the start of the cleaning water supply operation may be within the allowable cleaning start range from a certain position when the toilet lid 20 is being closed to a fully closed position during the closing operation of the toilet lid 20 . The timing (position) at which the toilet lid 20 reaches the earliest within the allowable range of the cleaning start is referred to as an allowable limit of the position of the toilet lid. As this allowable limit, it may be approximately 30 degrees as described above, or it may be other various toilet lid positions.

The judgment of the timing (position) of the cleaning start within the allowable range of the cleaning start can be carried out by the detection angle of the toilet lid opening and closing detection part 21, and can also be carried out by the elapsed time counted by the timing part 6. All of them are pre-measured to the arrival time or inclination angle θ of the toilet seat 20 until the timing (position) of the cleaning start, first stored as a constant, and the timing (position) of reaching the cleaning start is judged by comparing the actual measured value with the constant ) can be.

In addition, instead of the above-mentioned allowable limit of approximately 30 degrees, various allowable limits described below may be used as the allowable limit. In addition, about 30 degrees can also be positioned as the absolute limit of the Western-style toilet device 1 for preventing the spread of droplets (the limit position where the spread of droplets increases if the toilet lid 20 is opened more). That is, when the allowable limit defined by the positional relationship between parts is larger than about 30 degrees, the allowable limit may be set to about 30 degrees.

For example, the allowable limit of the position of the toilet lid that allows the start of the washing water supply operation can also be determined by the positional relationship between the appropriate position of the toilet lid 20 and the appropriate position of the toilet seat 24 when the closing action is being performed. For example, the states of the four examples shown in FIGS. 3( a ) to ( d ) may be used as the allowable limit.

In Fig. 3 (a), the height position of the lower edge 20ca of the front end 20c of the front end 20c of the peripheral wall surface 20b of the toilet lid 20 when the closing action is being performed is approximately the same as the height position of the top surface 24b of the toilet seat 24, and this can also be made The position of the toilet seat serves as the tolerance limit. That is, the supply operation of the washing water is started between the time when the toilet lid 20 is in the state shown in FIG. 3( a ) and it is completely closed.

In Fig. 3(b), the position of the intersection point X of the lower edge 20ba of the peripheral wall surface 20b of the toilet lid 20 when the closing action is being performed, and the top surface 24b of the toilet seat 24 in the closed state when viewed from the side is located at the closed position. The approximate middle position of the opening 24a of the toilet seat 24 in the front-rear direction of the state, and the position of the toilet lid can also be used as an allowable limit. That is, the washing water supply operation starts between the time when the toilet lid 20 is in the state shown in FIG. 3( b ) and is completely closed.

In Fig. 3(c), the position of the intersection X of the lower edge 20ba of the peripheral wall surface 20b of the toilet lid 20 when the closing action is being performed, and the top surface 24b of the toilet seat 24 in the closed state when viewed from the side is located at the closed position. The rear end edge 24aa of the opening 24a of the toilet seat 24 in this state can also use this toilet seat position as an allowable limit. That is, the washing water supply operation starts between the time when the toilet lid 20 is in the state shown in FIG. 3( c ) and is completely closed.

In Fig. 3(d), the position of the front end 20c of the peripheral wall surface 20b of the toilet lid 20 when the closing action is being performed approximately coincides with the position of the front end of the toilet seat 24, and this position of the toilet seat can also be used as an allowable limit. That is, the washing water supply operation starts between the time when the toilet lid 20 is in the state shown in FIG. 3( d ) and is completely closed.

As mentioned above, various assumptions are made on the allowable limit of the position of the toilet seat, corresponding to various shapes of Western-style toilet devices 1, that is, the shape of the toilet seat 20, the position of the rotating shaft 8, the positional relationship between the toilet seat 20 and the toilet seat 24, etc. , can adopt an appropriate form, and is not limited to the four examples shown in FIG. 3 . The toilet lid 20 and the toilet seat 24 may not move on the same rotation axis 8. In this case, an appropriate allowable limit may be adopted in consideration of the positional relationship between the two. In addition, an appropriate allowable limit may be determined in consideration of the amount of storage water in the tub 12, the amount of washing water, the water pressure, and the like.

In addition, the allowable limit itself may be used as the timing (position) of cleaning start. The four examples in FIG. 3 all show the situation where the allowable limit is the timing (position) of the cleaning start, that is, the cleaning starts at the timing when the toilet lid 20 reaches the state shown in FIG. 3 .

In addition, the timing (position) of the cleaning start in the cleaning start allowable range is determined by the inclination angle θ detected by the toilet cover opening and closing detection part 21 when the toilet cover 20 is closing, or the value measured by the timing part 6. The elapsed time from the start of the closing operation may be determined. In addition, a sensor may be provided at a suitable position of the toilet lid 20 or the toilet seat 24 to detect the timing (position) of the cleaning start within the allowable range of the cleaning start.

In order to determine the cleaning start timing (position) based on the inclination angle θ or the elapsed time in this way, it is sufficient to first determine a constant value by various tests or the like. For example, a constant value is first stored in a memory unit (not shown), and the timing (position) of cleaning start can be determined by comparing the changed inclination angle θ or the measured value of elapsed time.

In addition, if approximately 30 degrees is positioned as the extreme limit of the allowable limit, when setting the input constant value, if the constant value exceeds approximately 30 degrees or the corresponding time, it will be replaced with approximately 30 degrees or the corresponding time and saved That's it. In addition, it can also be checked in Fig. 4 and Fig. 5 whether the extreme limit is exceeded in the operation described later.

Next, the operation of the above-mentioned four examples of the Western-style toilet device 1 will be described based on the flow charts in Fig. 4 and Fig. 5 . These operations are all operations of the control unit 5 when a cleaning instruction is issued from the cleaning instruction means.

The basic actions of the four examples in Fig. 3 are all common. According to the inclination angle θ detected by the toilet lid opening and closing detection part 21, the action in Fig. 4 to judge the start of cleaning is carried out, or according to the process measured by the timing part 6 time, implement the action of Fig. 5 for judging the start of cleaning.

In the following action description, the detection of the open and closed state of the toilet lid 20 or the detection of the open and closed state of the toilet seat 24 depends on each detection unit, and the description of the action of these detection units will be omitted. In addition, the opening and closing operation of the toilet lid 20 or the opening and closing operation of the toilet seat 24 depends on each driving unit, and description of the operation of these driving units will be omitted.

First, the operation of FIG. 4 will be described according to the flowchart shown in steps S101 to S110. In the example of FIG. 4 , in order to determine the timing (position) of cleaning start, a constant value of the inclination angle θ is used, which is the comparison object of the actual measurement value of the inclination angle θ (for example, the angle between the toilet lid 20 and the toilet seat 24 ). .

When the washing instruction is received, if the toilet lid 20 is in the closed state, washing of the bowl 12 is carried out immediately thereafter (Y of S101 , S102 ). After the cleaning is completed, in order to confirm the inside of the user's bowl 12, the toilet lid 20 can also be opened, and after a certain period of time has passed since the open state, the toilet lid 20 in the open state can be closed to perform The action of fully closing.

When the cleaning instruction is received, if the toilet lid 20 is opened and the toilet seat 24 is also opened, the closing operation of the toilet seat 24 is started (N in S101, Y in S103, S104). Then, wait for the toilet seat 24 to be completely closed, and start the closing operation of the toilet lid 20 (Y of S105, S106).

Next, wait until the actually measured value of the inclination angle θ of the toilet lid 20 coincides with the constant value, and start cleaning at the timing of the coincidence or exceeding ( S107 , S108 ). Thereafter, the toilet lid 20 is completely closed.

In addition, in S103, if the toilet seat 24 is in the closed state and is in the off-seat state, the closing action of the toilet lid 20 is started, and then, the same action as above is carried out to start cleaning (N of S103, Y of S109, S106～ S108).

In addition, in S109 , when the seated state is detected, washing is started without closing the toilet lid 20 (N of S109 , S110 ).

Next, the operation of FIG. 5 will be described according to the flowchart shown in steps S201 to S212. In the example of FIG. 5 , a constant value of the elapsed time is used to determine the timing (position) of cleaning start, which is a comparison object of the actual measured value of the elapsed time.

When the washing instruction is received, if the toilet lid 20 is in the closed state, washing of the bowl 12 is carried out immediately thereafter (Y of S201 , S202 ). After the cleaning is completed, in order to confirm the inside of the user's bowl 12, the toilet lid 20 can also be opened, and after a certain period of time has passed since the open state, the toilet lid 20 in the open state can be closed to perform The action of fully closing.

When the cleaning instruction is received, if the toilet lid 20 is opened and the toilet seat 24 is also opened, the closing operation of the toilet seat 24 is first started (N in S201, Y in S203, and S204). Then, wait for the toilet seat 24 to be completely closed, and start the closing operation of the toilet lid 20 (Y of S205, S206).

Next, start counting according to the constant value of the elapsed time, wait until the time is up (time's up), and start cleaning when the time is up (Y in S207 and S208, S210). In addition, when the toilet lid 20 is completely closed before the time expires, washing is started even before the time expires (S208, S209). This is considering that the constant value of the elapsed time is larger than the closing operation time of the toilet lid 20 . In the case of starting cleaning before the toilet lid 20 is completely closed, the toilet lid 20 is completely closed thereafter.

In addition, in S203, if the toilet seat 24 is in the closed state and is in the off-seat state, the closing action of the toilet lid 20 is started, and then, the same action as above is carried out to start cleaning (N in S203, Y in S211, S206- S210).

In addition, in S211, when the seated state is detected, washing is started without closing the toilet lid 20 (N of S211, S212).

As mentioned above, when cleaning the bowl 12, as shown in the example of FIG. 1(b) or the fourth example of FIG. Therefore, the diffusion of droplets from the tub 12 is suppressed. In addition, as in these examples, cleaning starts before it is completely closed, so cleaning the tub 12 as soon as possible can shorten the waiting time for users who want to confirm cleaning.

For example, in a restroom with an unspecified number of users or a restroom that is frequently used, it is appropriate to use Figure 3(a) and Figure 3(b) from the viewpoint of preventing the spread of droplets. On the other hand, in toilets such as households, Fig. 3(c), Fig. 3(d) and the like can also be used.

Next, the operation shown in the flowchart of FIG. 6 (steps S301 to S310 ) will be described. The action in this figure is when the toilet lid driver 22 changes the driving force when the closing action is being performed, as the timing of the cleaning start.

When the washing instruction is received, if the toilet lid 20 is in the closed state, washing of the bowl 12 is carried out immediately thereafter (Y of S301 , S302 ). After the cleaning is completed, in order to confirm the inside of the user's bowl 12, the toilet lid 20 can also be opened, and after a certain period of time has passed since the open state, the toilet lid 20 in the open state can be closed to perform The action of fully closing.

When the cleaning 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 (N in S301, Y in S303, and S304). Then, wait for the toilet seat 24 to be completely closed, and start the closing operation of the toilet lid 20 (Y of S305, S306).

Next, it waits for a timing when the driving force of the toilet lid driving unit 22 increases, and starts washing at that timing ( S307 , S308 ). Thereafter, the toilet lid 20 is completely closed.

In addition, in S303, if the toilet seat 24 is in the closed state and is in the off-seat state, the closing action of the toilet lid 20 is started, and then, the same action as above is carried out to start cleaning (N in S303, Y in S309, S306～ S308).

In addition, in S309, when the seated state is detected, washing is started without closing the toilet lid 20 (N of S309, S310).

The timing of the increase of the driving force is as described above immediately before the toilet lid 20 is completely closed, that is, the state of FIG. 3( a ), or is closer to the fully closed state. By this action, the same effect as the above example is also achieved.

As the Western-style toilet device 1, the toilet seat 24 and the toilet lid 20 may be replaced integrally. In particular, it can also be a western-style toilet device 3 with additional (or replacement) toilet seat device 30 as shown in FIG. 7 .
