Made.
[0004]
[Problems to be solved by the invention]
However, in the conventional Western-style flush toilet, the on-off valve may be in an abnormal state due to mischief or failure of the toilet cleaning device. If this abnormal state is left unattended, the cleaning water will continue to flow, resulting in wasted consumption of the cleaning water.
[0005]
This invention is made | formed in view of the said situation, and makes it the problem which should be solved to provide the western-style flush toilet bowl which does not consume washing water wastefully.
[0006]
[Means for Solving the Problems]
The Western-style flush toilet of the present invention comprises a Western-style toilet body and a toilet bowl cleaning device capable of cleaning the Western-style toilet body with washing water, and the toilet bowl cleaning device is electrically opened and closed to allow the washing water to be discharged. In a Western style flush toilet with a valve,
[0007]
The toilet cleaning device includes a detecting unit that detects an abnormal state of the on-off valve, and a return signal that closes the on-off valve after performing at least a sealing process on the western-style toilet body by an abnormal signal of the detecting unit Means.
[0008]
In the Western style flush toilet of the present invention, even if the on-off valve is in an abnormal state, an abnormal signal is generated by the detecting means, and the on-off valve is automatically closed by the return means.
[0009]
Therefore, in this Western style flush toilet, water supply is automatically stopped, and washing water is not consumed wastefully.
[0010]
In the Western-style flush toilet of the present invention, the toilet bowl cleaning device preferably has a notification means for notifying an abnormal state by an abnormal signal from the detection means. This is because the user can know that there is some abnormality in the toilet bowl cleaning device, and can quickly take countermeasures.
[0011]
As the detection means, a position sensor, a flow rate sensor, a water pressure sensor, or the like can be employed. As the notification means, for example, a device that generates an electronic sound or a device that blinks a light emitting diode can be employed.
[0012]
Moreover, in the western flushing toilet of the present invention, the return means, after at least sealing water treatment Western-style toilet body, you off valve in the closed state. If this is the case, even if the on-off valve is in an abnormal state, the inside of the trap is sealed with water, and it is possible to prevent a strange odor from rising through the drain pipe.
[0013]
In this case, the return means can also close the on-off valve after performing the normal washing process of the Western-style toilet body. In this case, even if the on-off valve is in an abnormal state, the western toilet body is washed at least once, and the western toilet body is reliably washed. For this reason, filth does not remain, it is possible to prevent the generation of unpleasant odors, and it is hygienic.
[0014]
The Western-style flush toilet of the present invention comprises a Western-style toilet body and a toilet bowl cleaning device capable of cleaning the Western-style toilet body with washing water, and the toilet bowl cleaning device can be electrically opened and closed to discharge washing water In a Western-style flush toilet having an open / close valve, the toilet bowl cleaning device includes a detecting means for detecting an abnormal state of the open / close valve and a return means for closing the open / close valve by an abnormal signal of the detecting means. Then, the return means stops the open / close valve in the closed state when the retry for performing the normal cleaning process after returning the open / close valve to the closed origin is over a certain number of times . If this is the case, even if it is impossible to perform the normal cleaning process of the western-style toilet body due to the abnormal state of the on-off valve, the retry water will not be repeated infinitely, and the cleaning water will eventually flow. There is nothing. For this reason, it is possible to prevent wasteful consumption of energy and wasteful washing water.
[0015]
As the on-off valve, a valve driven by a stepping motor can be adopted. In this case, the detection means can detect the state of the on-off valve by the number of pulses corresponding to the rotation angle of the stepping motor. As a result, it is possible to easily control the on-off valve using the pulse signal and to easily detect the current state of the on-off valve.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described with reference to the drawings.
[0017]
The schematic diagram of the western style flush toilet of embodiment is shown in FIG. This Western-style flush toilet uses a tankless system that does not have a water supply tank, and has a Western-style toilet body 1, a toilet bowl cleaning device 2, a heating toilet seat (not shown), and a toilet lid (not shown).
[0018]
The western-style toilet body 1 is made of ceramic. The toilet bowl cleaning device 2 is directly connected to the water pipe 3 by a flexible hose 5 via a stop cock 4, and the western-style toilet body 1 can be cleaned by discharging the cleaning water a and the cleaning water b.
[0019]
As shown in FIG. 2, the toilet flushing apparatus 2 includes a rim on-off valve 6a and a jet on-off valve 6b. A cam device is provided above the rim on-off valve 6a and the jet on-off valve 6b. 6c is provided, and a stepping motor 6d is provided on the side of the cam device 6c. The cam device 6c is driven by a stepping motor 6d. When the cam device 6c is driven, the rim on-off valve 6a and the jet on-off valve 6b are opened and closed.
[0020]
A controller 7 is electrically connected to the stepping motor 6d, and the controller 7 can be operated by a remote controller 8. As shown in FIG. 3, the controller 7 includes a motor drive circuit 7a and a position sensor 7b connected to the stepping motor 6d, a pulse oscillation circuit 7c connected to the motor drive circuit 7a and generating a pulse signal, and a position sensor 7b. And a return circuit 7d for returning an abnormal state of the rim on-off valve 6a and the jet on-off valve 6b. Here, the position sensor 7b detects the open / close state of the rim on / off valve 6a and the jet on / off valve 6b from the pulse signal transmitted to the stepping motor 6d. The return circuit 7d is connected to a warning device 9 as notification means provided in the Western style flush toilet.
[0021]
In the Western-style flush toilet constructed as described above, the controller 7 performs the cleaning process according to the flowcharts shown in FIGS. 4 and 5 by the return circuit 7d and the storage means (not shown).
[0022]
When the user presses the cleaning start button of the remote controller 8, first, a normal cleaning process is performed according to the flowchart shown in FIG. That is, in step S102, it is determined whether or not both the rim on-off valve 6a and the jet on-off valve 6b are closed. At this time, since it is necessary to determine the reference of the number of pulses transmitted to the stepping motor 6d, it is assumed that it is “origin” if both the rim on-off valve 6a and the jet on-off valve 6b are closed.
[0023]
Here, if it is “origin”, the process proceeds to step S104. As a result, the stepping motor 6d rotates at a certain angle and stops, and the rim on-off valve 6a is opened. For this reason, the washing water a is discharged for a certain time, and the filth collects in the trap.
[0024]
In step S106, it is determined whether or not the rim on-off valve 6a is open and the jet on-off valve 6b is closed. If “YES” here, the process proceeds to a step S108. As a result, the stepping motor 6d rotates by a fixed angle and stops, the rim on-off valve 6a is closed, and the jet on-off valve 6b is opened. For this reason, the washing water a is stopped, and the washing water b is discharged for a certain time to forcibly produce a siphon effect, and the filth is discharged.
[0025]
In step S110, it is determined whether or not the rim on-off valve 6a is in a closed state and the jet on-off valve 6b is in an open state. If “YES” here, the process proceeds to a step S112. As a result, the stepping motor 6d rotates at a certain angle and stops, the jet on / off valve 6b is closed, and the rim on / off valve 6a is opened. For this reason, the cleaning water b is stopped, the cleaning water a is discharged for a certain time, and the sealing process of the trap is performed.
[0026]
Next, the process proceeds to step S114, and it is determined whether or not the rim on-off valve 6a is in an open state and the jet on-off valve 6b is in a closed state. If “YES” here, the process proceeds to a step S116. As a result, the stepping motor 6d rotates by a predetermined angle and stops, and the process proceeds to step S118. Thereby, it is determined whether or not both the rim on-off valve 6a and the jet on-off valve 6b are closed. If “YES” is determined here, the process is in a stand-by state, and the cleaning process is ended.
[0027]
On the other hand, if NO in step S102, step S106, step S110, step S114, and step S118, it is an abnormal state, and abnormal processing is performed according to the flowchart shown in FIG.
[0028]
That is, first, in step S202, an electronic sound notifying that there is an abnormal state is generated by the warning device 9, and a process of returning to the “origin” is performed. Thereafter, the process proceeds to step S204, and it is determined whether or not the “origin” is normally returned. If "YES" here, the process proceeds to a step S206 to determine how many times the retry has been repeated. If the number of retries is less than n, the result is NO, and the warning device 9 displays that the retry is being performed in step S208. Thereafter, the process returns to step S102 shown in FIG. 4 to perform a normal cleaning process. Steps S202, S204, S206, and S208 in the return circuit 7d and the storage device are return means.
[0029]
On the other hand, if it is determined in step S206 that the number of retries is n or more, the determination is YES, and the process proceeds to step S210. As a result, it is possible to prevent retries from being repeated infinitely and energy being wasted.
[0030]
In step S210, it is determined how many times the number of retries is determined to be n or more. If the number of times is not more than i, YES is set and the state is kept as it is. If the number of retries determined to be n or more is greater than i, the determination is NO, the process proceeds to step S212, and “Warning prohibited” is displayed by the warning device 9 and then a standby state is entered. As a result, the user can be informed that a failure has occurred.
[0031]
On the other hand, if it is determined in step S204 that the original position has not been returned to the “origin”, the determination is NO and the process proceeds to step S214. Here, the number of times the return processing to the “origin” has not been normally performed is compared. If the number is less than m, NO is returned and the process returns to step S202. On the other hand, if this number is greater than or equal to m times, the answer is YES, and the process proceeds to step S216, where the warning device 9 displays “cleaning prohibited”. Thereafter, the process proceeds to step S218, where “forced water stop” is displayed by the warning device 9, and then the standby state is set. As a result, it is possible to prevent the process of returning to the “origin” from being repeated infinitely and consuming energy wastefully.
[0032]
As described above, in the Western style flush toilet of this embodiment, even if the rim on / off valve 6a or the jet on / off valve 6b is in an abnormal state, this is detected by the position sensor 7b, and the return circuit 7d or the like. The rim on-off valve 6a and the jet on-off valve 6b are automatically returned to the closed state.
[0033]
Therefore, in this Western style flush toilet, water supply is automatically stopped, and washing water is not consumed wastefully.
[0034]
Further, since the Western-style toilet body 1 is sealed in the return circuit 7d and the like, even if the rim on-off valve 6a or the jet on-off valve 6b becomes abnormal, it is possible to prevent a strange odor from rising through the drain pipe. it can.
[0035]
Further, the return circuit 7d and the like perform the normal cleaning process of the western-style toilet body 1, and then close the rim on-off valve 6a or the jet on-off valve 6b. Even if the valve 6b is in an abnormal state, the normal cleaning process of the Western-style toilet body 1 is performed at least once, and the Western-style toilet body 1 is cleaned almost certainly. For this reason, filth does not remain, it is possible to prevent the generation of unpleasant odors, and it is hygienic.
[0036]
Further, since the return circuit 7d and the like stop the rim on-off valve 6a or the jet on-off valve 6b in a closed state when a certain number of retries are exceeded, the retry is not repeated infinitely, and finally the washing water is discharged. It doesn't stay flowing. For this reason, it is possible to prevent wasteful consumption of energy and wasteful washing water.
