DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary device which is detachably attached to a toilet, and more particularly to a sanitary device capable of promptly and surely coping with an abnormality in a function unit incorporated in the sanitary device.

[0002]

2. Description of the Related Art Conventionally, a sanitary device has been used by being attached to a toilet bowl. Male urinals are used when the toilet device is used. In the case where the sanitary device is a local cleaning device, splashing water spouted from a nozzle is used. Due to such factors, it is always wet.
As a result, the sanitary device is contaminated, and dust and the like adhere thereto. Therefore, in recent years, an apparatus has been provided in which a sanitary device is detachably attached to a toilet, and cleaning of a gap between the toilet and the sanitary device and cleaning of the sanitary device in an easy posture are provided.

[0003]

However, since the sanitary apparatus is detachable in consideration of the sanitary aspect of the sanitary apparatus,
The possibility that the original function of the sanitary device is impaired is increased, and a problem that maintenance is troublesome is newly raised. That is, this type of sanitary device is used by being mounted on a toilet horizontally fixed to a toilet, and its product specifications are designed on the premise of horizontal fixing. When removing the sanitary device of such specifications from the toilet bowl and cleaning it, the sanitary device should be treated completely different from normal operation, such as turning over, inserting foreign objects such as rags, removing connectors etc. become.

[0004] In the conventional sanitary apparatus, such sanitary apparatus is not sufficiently taken into consideration in handling in a state where the sanitary apparatus is detached from the toilet, and when the sanitary apparatus is re-attached to the toilet, the function of the sanitary apparatus may be affected. Even if it is, it was not possible to cope with this at all, and it was not possible to achieve both maintenance and cleanability.

[0005]

Means for Solving the Problems A sanitary apparatus according to a first aspect of the present invention for solving the above-mentioned problems has a built-in functional unit for performing a predetermined operation, and is used detachably mounted on a toilet. In the device, mounting detection means for detecting whether or not the mounting on the toilet is completed, and diagnosing an abnormality of the functional unit when the mounting detecting means detects that the mounting on the toilet is completed. It is characterized by comprising an abnormality detecting means and a processing executing means for executing processing according to the diagnosis result of the abnormality detecting means.

According to the sanitary device of the first invention, the mounting detecting means detects whether or not the mounting of the sanitary device on the toilet is completed. When the sanitary equipment, which has been treated differently than normal, is returned to normal use, it is automatically determined whether or not there is a problem with the functional part. Diagnosis is performed, and appropriate processing can be performed in the event of an abnormality. This makes it possible to remove the sanitary device from being used in an abnormal state by removably ensuring the cleanability of the sanitary device and diagnosing and coping with the abnormality at the time of reattachment.

[0007] If an abnormality is detected by the abnormality detecting means, the operation of the function unit is prohibited by the processing executing means, so that the use of the sanitary apparatus in an abnormal state can be completely prevented, and the abnormality can be prevented. Ripple can be prevented. In particular, by prohibiting the operation of only the functional unit that is detected as abnormal, it is possible to prevent the device from being completely unusable.

Further, if the processing executing means notifies the detection result of the abnormality detecting means by the notifying means, the detection result can be easily notified to the user, and the maintenance work by the user can be facilitated. That is, if there is a notification of an abnormality at the time of re-attachment after cleaning, the user performs immediately before, and from the new cleaning content and the notification content in the memory, the location where the abnormality occurred, the content of the occurring abnormality, etc. are instantaneous. Judgment can be made, and maintenance and countermeasures become easy. For example, maintenance work corresponding to the cleaning content performed immediately before, such as wiping a wet part of an electronic circuit, attaching a connection cord, and removing a piece of a sandwiched rag is performed.

Further, the functional unit includes an electric circuit for performing a predetermined operation, and the abnormality detecting means determines abnormality by determining whether a voltage at a predetermined portion of the electric circuit is within a range considered to be normal. This is effective, for example, because it is possible to diagnose an abnormality in an electric circuit that cannot be visually judged, such as a short circuit caused by water wetness.

[0010] Further, as a functional part, a nozzle is provided which can be moved to a position suitable for discharging washing water to a local part of a user seated on the toilet, and the abnormality detecting means is a nozzle position and / or a force required for nozzle movement. If it is decided to determine the presence or absence of an abnormality, it is easy to become dirty, and frequent cleaning is performed.
Maintenance can be simplified.

[0011] Further, a toilet seat having a built-in heater detachably connected to the sanitary device main body via a connector is provided as the functional unit, and the abnormality detecting means detects a connection state of the connector to the heater (mechanical connection). If the sanitary device is removed from the toilet and cleaning is performed, it is common to disconnect these connections and reconnect after cleaning. This is extremely effective because it can be diagnosed whether or not the operation has been performed reliably.

A sanitary device according to a second aspect of the present invention for solving the above-mentioned problems is provided in a housing having a built-in functional unit for assisting the excretion operation and the waste cleaning operation using the toilet. In a sanitary device having a detachable mounting portion, when the mounting portion detects that the mounting on the toilet is completed, the mounting detecting portion detects a state in which the mounting portion is mounted on the toilet. Abnormality detecting means for detecting an abnormality in the functional unit, and recovery processing executing means for executing processing for recovering the functional unit to normal when the abnormality detecting unit detects an abnormality. And

According to the sanitary device of the second aspect, the mounting state detecting means detects whether or not the mounting portion is mounted on the toilet, and when it is detected that the mounting portion is mounted on the toilet, the function checking means is provided. When an abnormality of the functional unit is detected, and when the abnormality is detected, a process for restoring the function to a normal state is executed by the recovery processing execution unit.

Therefore, the sanitary device of the second invention, like the sanitary device of the first invention, is detachable so that cleanability of the sanitary device is ensured and maintenance is simplified by automatic inspection upon re-attachment. Becomes In addition, when an abnormality is detected as a result of the inspection, the function is restored, so that the labor required for the maintenance of the user can be greatly reduced and the function can be used immediately after cleaning.

[0015] The apparatus may further include, as the functional unit, a heat exchanger for converting washing water supplied from the outside to clean the human body part into warm water and storing the same, and wherein the recovery processing execution means detects a shortage of water in the heat exchanger. If the device is equipped with a means for supplying water to the heat exchanger, the amount of stored water will be reduced if the device is removed from the toilet bowl due to water leakage or drainage by the user. However, it is very effective because the hot water can be automatically inspected after cleaning, and the hot water can be automatically re-stored in accordance with the inspection result, and the storage amount required for use can be reliably secured.

[0016] In addition, the function unit includes a nozzle movable to a position suitable for discharging flush water to a local part of a user seated on the toilet, and the recovery processing execution means cannot control the movement of the nozzle. If it is determined that the nozzle is reciprocated, the nozzle can be reciprocated by performing the nozzle reciprocating operation even in a case where the nozzle is pulled out at the time of cleaning and foreign matter is caught and the nozzle cannot be controlled to a predetermined advance position. In addition, the caught foreign matter can be discharged.

[0017]

Another aspect of the present invention, the functional part in the sanitary device of the first invention and the functional part in the sanitary device of the second invention are a roll-shaped thin leaf (leaf leaf) set in a case attached to the rear of the toilet. Is thin, flexible and has an area enough to cover the toilet seat), a predetermined amount is fed out onto the toilet seat by a pair of rollers, and cut into a single use. In the meantime, when the thin leaf is easily detached from the toilet when the holding state with the roller is easily lost, the thin leaf is frequently re-clamped, so that the maintenance can be further simplified.

The mounting detecting means in the sanitary device of the first invention and the mounting state detecting means in the sanitary device of the second invention are simply constituted by a mechanical switch such as a microswitch, but use magnetism. If the switch is an electric or non-contact switch such as a proximity switch, the switch is not disposed outside which is easily contaminated, which is effective for detection accuracy and cleanability.

The notification means may use a display unit for displaying the use state of the function unit when the function unit is used.
For example, if the LED that lights when the cleaning water is being discharged from the local cleaning nozzle blinks when the nozzle movement is abnormal, the user can visually identify the occurrence of the functional abnormality to the user without providing a special notification unit. Can be informed. Also,
Instead of the display unit, the notification unit may be a sound generation unit that notifies the contents of the abnormality by generating a sound. In this case, it is not always necessary to arrange at a position visible to the user, and the degree of freedom in design increases.

In the case where the sanitary device has a self-check function for checking the operation of the functional unit when the product is shipped or when the power is turned on after construction, the abnormality detection in the sanitary device according to the first and second inventions is performed. If these self-check functions are used as means, the configuration is simplified. In other words, a configuration may be adopted in which it is determined that the mounting on the toilet is completed, and the self-check function is operated as if the power was turned on after construction.

Next, a process of detecting an abnormality in the sanitary washing function unit when the sanitary washing device 20 is mounted on the Western style toilet 21 will be described.

FIG. 10 shows a first embodiment in which, when the attachment / detachment sensor 250 detects that the sanitary washing device 20 has been attached to the Western-style toilet 21, the CPU 152 interrupts other processes and gives priority to the process. 6 is a flowchart showing an outline of an abnormality diagnosis process performed.

In the first step S82, an abnormality detection process is executed. The abnormality detection processing performed here is a set of the following various inspections.

1) Check whether the electronic control unit 150 operates normally. The purpose of separating the sanitary device from the Western toilet 21 is to clean the sanitary washing device 20 and the like.
Sanitary washing device 2 such as separating the
0 may be tilted from the normal mounting position. Therefore, when the sanitary washing device 20 is in the detached state, there is a high possibility that the electric conduction of the electronic control device 150 may be abnormal due to water leakage from the inclined heat exchanger 130, water for cleaning, or detergent.

Therefore, it is determined whether or not input voltage values from various sensors such as the thermistor 128a and the float switch 131 input to the input processing circuit 158 are within the normal operation range. Further, it is determined whether or not the input voltage value from various operation buttons such as the bottom cleaning button 210a and the bidet cleaning button 210b is within the allowable range of the logical levels “L” and “H”.

2) Inspection of connector connection of the power cable 27 and the like. Usually, the power cable 27 of the toilet seat 28 connected to the case body 22 by the power cable 27 is removed. Therefore, the connection of the power cable 27 is confirmed by applying power to the thermistor (not shown) provided in the toilet seat 28 from the output processing circuit 159 and detecting whether or not a current flows through the thermistor. That is, since the signal lines of the power cable 27 and the thermistor are connected via the same connector, the connection state of the connector can be detected by detecting whether or not the thermistor signal line is connected.

3) Driving device 14 for moving nozzle 24 forward and backward
This is the inspection of No. 1. In order to clean nozzles that are easily contaminated by normal use, the nozzles 24 are generally extended and cleaning is performed using a rag or the like. Therefore, there is a possibility that a scrap of a rag is caught in the driving device 41 of the nozzle 24 during the cleaning. Therefore, it is determined whether the position of the nozzle 24 is at the storage position by a limit switch (not shown) provided on the output shaft of the driving device 141, and it is determined whether the nozzle driving can be actually performed.

When the abnormality detection processing in step S82 is completed, the processing is executed in step S84 based on the inspection result of the abnormality detection processing in step S82. The processing includes storing the contents of the abnormality in the backup RAM 157 and disabling the operation of the functional unit targeted for the abnormality and notifying the user of the fact.

The notification performed here is an aggregate of various types of notification performed in the following manner with respect to the abnormality detection.

1) When the input values from the thermistor 128a and the float switch 131 are not within the normal operation range, the output processing circuit 159 sets the water discharge temperature setting button 21
LED 210g1 near 0g, buttocks washing button 210a
The adjacent LEDs 210a1 are turned on and off, respectively. Also,
The input values from the operation buttons such as the buttocks washing button 210a and the bidet washing button 210b are logical levels "L" and "H".
Is not within the allowable range, the output processing circuit 159 causes the LEDs 210a1,
The LED 210b1 near the bidet cleaning button 210b is blinked. Further, when the washing water heater 129 does not operate normally, the output processing circuit 159 blinks the LED 210g1 near the water discharge temperature setting button 210g.

2) When no current flows through the thermistor provided with the toilet seat heater 153, or when the resistance value of the thermistor is not within a predetermined range, the output processing circuit 15
9, LED near the toilet seat heating on / off button 210k
Blink 210k1.

3) When nozzle driving cannot be actually performed, for example, when the nozzle position is not at the mechanical origin, the LED 210i1 near the nozzle position adjusting button 210i is blinked by the output processing circuit 159.

As described above, when the sanitary apparatus treated differently from the normal state is returned to the normal use state, it is automatically diagnosed whether or not a trouble has occurred in the functional unit. Accordingly, the sanitary device can be easily cleaned by being detachable, and maintenance is simplified by automatic inspection at the time of re-attachment. In the abnormality detection processing, the electronic control unit 150
Is being tested for normal operation. Therefore, it is possible to inspect even an abnormality that cannot be visually judged, such as a short circuit caused by water wetting.

The driving device 1 for moving the nozzle 24 forward and backward
An operation test of 41 is performed. Therefore, it is easily contaminated,
Maintenance for nozzles that are frequently cleaned can be simplified.

Inspection of connector connection of the power cable 27 and the like is performed. Therefore, it is possible to surely check whether or not the connector connection, which is generally disconnected when the sanitary device is removed from the toilet and cleaned, is connected after cleaning.

Further, in the above embodiment, since the detection result detected by the detection means is notified, the detection result can be easily notified to the user, and the maintenance work by the user can be facilitated. That is, if there is a notification of an abnormality at the time of re-attachment after cleaning, the user performs immediately before, and from the new cleaning content and the notification content in the memory, the location where the abnormality occurred, the content of the occurring abnormality, etc. are instantaneous. Judgment can be made, and maintenance and countermeasures become easy. Note that, in the above-described embodiment, since the LED which is originally provided to indicate the use state of the sanitary washing device 20 is used, it is not necessary to provide a special notification unit, which is advantageous in cost. It is.

Further, if the detection result detected by the detecting means is stored in the backup RAM 157, the history of troubles caused at the time of attachment / detachment can be used for maintenance work by a maintenance worker corresponding to a failure caused in another case. it can. In other words, the maintenance worker in the event of a failure or the like uses the abnormality history at the time of reattachment after cleaning,
The cause of the abnormality that has occurred can be estimated, and maintenance and countermeasures are facilitated.

FIG. 11 shows, as a second embodiment, when the attachment / detachment sensor 250 detects that the sanitary washing device 20 has been attached to the Western-style toilet 21, the CPU 152 interrupts other processing and executes the processing preferentially. FIG. 9 is a flowchart of a program showing an inspection process executed at 0.5 intervals thereafter.

In the first step S100, the counter C
Is incremented. The counter C is a counter that measures the time during which the main inspection process is continued. Next, proceeding to step S102, as an inspection of the functional unit, for example,
The water level of the heat exchanger 130 is checked by a float switch 131 which outputs an ON signal when the heat exchanger 130 is full and an OFF signal when the water level is low and the water level is low. Here, the purpose of checking the water level of the heat exchanger 130 is to separate the sanitary washing device 20 from the toilet 21 for the purpose of cleaning the sanitary washing device 20 and the like.
0 is tilted from the normal mounting posture, or an operation different from the normal use state is performed. Therefore, the state is different from the normal use state, such as water leakage from the heat exchanger 130 or drainage in advance.

Next, the process proceeds to step S104, where it is determined whether or not a recovery process is necessary. Then, when it is determined that the signal from the float switch 131 inspected in step S102 is an ON signal and the recovery process is not necessary (S10)
4N), the process proceeds to step S112, the LED 210a1 near the buttocks washing button 210a is turned on to notify that the inspection result is normal, the counter C is reset in S114, and the interrupt process ends. On the other hand, when it is determined in step S104 that the off signal, that is, the recovery process is necessary (Y in S104), the process proceeds to step S106.

Next, in step S106, it is determined whether or not the counter C is within Cmax (arbitrary value, but here, "120"). In step S106,
If it is determined that the counter C is not within Cmax (S
106N) Since the recovery process described later has continued for a predetermined period of time, it can be determined that recovery is impossible, so that step S1 is performed.
Proceeding to No. 16, the heater 129 forbidding input from the buttocks cleaning button 210a and the bidet cleaning button 210b is prohibited.
The operation of the functional unit determined to be abnormal is disabled by, for example, prohibiting energization of the functional unit. However, when the operation of the functional unit is prohibited as described above, the fact that the abnormality has not been recovered may be notified and the fact may be stored in the backup RAM 157 to promote the necessity of maintenance. desirable. Then, in step S114, the counter C is reset, the interrupt processing of this program is terminated, and the program returns to the normal program.

In step S106, the counter C
Is determined to be within Cmax, step S
Proceeding to 108, a recovery process is performed. Here, the recovery processing to be performed is to temporarily open the electromagnetic valve 124 by the output from the output processing circuit 159. After that, the LED 210a1 near the buttocks washing button 210a is blinked in step S110 to notify that the recovery process is being performed. Then, one process of this program is ended.

As described above, when the sanitary apparatus which has been treated differently from the normal state is returned to the normal use state, the functional means is inspected to make the sanitary apparatus detachable similarly to the first embodiment. This not only ensures cleanliness of the sanitary equipment, but also facilitates maintenance due to automatic inspection upon re-attachment. Since the detection result is stored, the inspection result is transmitted, and the like, the labor required for the maintenance of the user can be significantly reduced.

In particular, in the second embodiment, the heat exchanger 130 which is in a state different from a normal use state, such as a state in which stored water leaks during cleaning or is drained in advance by a user. It is very effective because it performs an automatic inspection of

The present invention is not limited to the above-described embodiment, but can be embodied in various forms without departing from the scope of the invention.
The following modifications are also possible.

02, a driving device 141 for moving the nozzle 24 forward and backward
Check the operation of. Nozzle 2 that is easily soiled by normal use
4 is generally performed by extending the nozzle 24 and cleaning with a rag or the like. Therefore, there is a possibility that a scrap of a rag or the like is caught in the driving device 141 of the nozzle 24 during the cleaning. Therefore, it is checked whether or not the nozzle 24 is at the mechanical origin. In step S104, whether or not the nozzle 24 is at the mechanical origin
It is determined whether the recovery process is necessary. Step S108
Then, a signal for causing the nozzle 24 to advance / retreat as much as possible is transmitted to the driving device 141 through the output processing circuit 159. In step S110, the LED 210i1 near the nozzle position adjustment button 210i is turned on. In step S110, the LED 210 near the nozzle position adjustment button 210i is turned on.
