Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention smoothly discharges various kinds of waste water (miscellaneous waste water, human waste, etc.) discharged from various water supply / drainage facilities such as toilets, bathtubs, sinks for sinks, sinks for kitchens, and pans for washing machines. TECHNICAL FIELD The present invention relates to a drainage / pressure supply device, a water supply / drainage system including the drainage pressure supply device, and a water supply / drainage facility monitoring system for remotely monitoring a water supply / drainage facility.

[0002]

2. Description of the Related Art In recent years, a type of forced discharge device called a drainage pumping device has come to be used for discharging drainage from a water supply and drainage facility such as a toilet to the outside.
Generally, a drainage pumping device includes a storage tank that temporarily stores the drainage water from the water supply and drainage facility, a pump that sucks and discharges the drainage water that has collected in the storage tank, and a pumping pipe that is connected to a discharge port of the pump. It is configured.

[0003]

In a water supply / drainage facility using such a drainage pumping device for discharging, unlike the conventional one using a natural downflow due to a slope gradient, the drainage pumping device itself malfunctions and operates. When it disappears, it has a fundamental problem that drainage cannot be discharged. Especially when the drainage pumping device is used to discharge from the toilet bowl of the toilet, the drainage pumping device incorporates a crushing device for crushing sewage. It causes a serious problem of being completely unusable.

Further, when a drainage pumping device is provided for each toilet in a toilet booth provided with a plurality of toilet private rooms such as public toilets used by many people, maintenance and management of the drainage pumping device are very troublesome. .

The present invention has been made in view of the above points, and its main purpose is to predict the occurrence of a failure of the drainage pumping device and take appropriate measures such as repair and replacement. A drainage pumping device, a water supply / drainage system, and a water supply / drainage facility monitoring system capable of performing

[0006]

[Means and Effects for Solving the Problems] Failures of the drainage pumping device can be roughly classified into two. That is, for example, a failure that suddenly occurs due to carelessness in use (for example, flowing solid matter that is difficult to crush into the toilet),
This is a failure due to the so-called service life of the product, such as deterioration of the drive unit such as a pump over time. The former failure is practically impossible to predict in advance of its occurrence. In contrast,
Since the latter failure is related to the operating time of the drive unit and the like, it is possible to predict that the failure will be close before the failure actually occurs.

In order to solve the above-mentioned problems, the drainage pumping apparatus according to the present invention has a crushing means for crushing the solid matter mixed in the wastewater discharged from the water supply and drainage facility, and a wastewater containing the crushed solid matter to the outside. The drainage pumping apparatus including a pumping means for pumping to the drainage apparatus is characterized by including operation information acquiring means for acquiring operation information according to the number of operations or the operating time of the drainage pumping apparatus.

The operation information acquisition means acquires information relating to the life of the present apparatus or the drive section constituting the present apparatus, such as the number of operations and the operating time of the drainage pumping apparatus. According to this information, it is possible to know the time when it is appropriate to take measures such as repair or replacement of parts before a trouble such as a failure occurs. Therefore, it is possible to avoid with an extremely high probability an undesired situation in which the crushing means and the pressure feeding means suddenly break down and the water supply / drainage equipment becomes unusable.

As a typical aspect of the drainage pumping apparatus according to the present invention, the pumping means includes a motor for driving a pump for sucking and discharging the drainage, and the operation information acquiring means is the number of times or operating time of the motor. Can be configured to count. Further, as another aspect, the crushing means includes a cutter and a motor for driving the cutter,
The operation information acquisition means may be configured to count the number of times or the operation time of the motor. Of course, when the pump and the cutter operate simultaneously or in conjunction with each other, the number of times the pump is used and the number of times the cutter is used are the same.

Further, the operation information acquisition means may fail or malfunction due to some cause. Therefore, in order to improve reliability, a plurality of operation information acquisition means are provided. It is preferable to determine whether or not the failure is near based on the information by at least one of the operation information acquisition means.

Further, in the water supply / drainage system comprising a water supply / drainage facility such as a toilet bowl of a toilet, a water supply device for supplying water to the water supply / drainage facility, and a drainage pumping device for pumping the wastewater discharged from the water supply / drainage facility, In order to solve the problem, information corresponding to the operation of the water supply device can be used instead of the drainage pumping device. That is, the water supply / drainage system according to the present invention is characterized by including water supply information acquisition means for counting the number of times the water supply device supplies water to the water supply / drainage facility.

In most cases, the water supply operation corresponds to the above-described pressure feeding operation or crushing operation. Therefore, based on the number of times the water is supplied by the water supply apparatus, the pressure feeding means and crushing means included in the drainage pumping apparatus The life of the motor can be estimated almost accurately. If the water supply and drainage facility is a toilet bowl,
Water supply from the water supply device is often performed by mechanically operating the lever. In such a structure, the water supply information acquisition means only needs to mechanically detect the operation of the lever. Is extremely simple and costs little to increase.

Further, the drainage pumping apparatus or the water supply / drainage system according to the present invention is further provided with an informing means for informing the outside based on the information obtained by the operation information acquiring means or the water supply information acquiring means. It is preferable. According to this configuration, for example, when the possibility that a count result exceeds a predetermined number of times and a failure occurs, the notification means can notify the user to that effect. The notification means may be, for example, a display means such as an indicator light, but a sound generation means using a buzzer or a synthetic voice is effective for calling the user's attention.

Further, since the purpose of the notification means is to warn the user of a failure prediction, the notification means is provided with a water supply / drainage facility such as a toilet so that the user can easily know the notification. It is preferable that it is arranged above the floor surface.

Further, since it is assumed that the notification means itself may break down, a plurality of notification means may be preferably provided.

Furthermore, in the drainage pumping apparatus or the water supply / drainage system according to the present invention, arithmetic processing means for arithmetically processing the information obtained by the operation information acquisition means or the water supply information acquisition means based on a predetermined algorithm is constructed. May be The "arithmetic processing means for performing arithmetic processing based on a predetermined algorithm" here means not only simple processing such as counting the number of operations, but also means capable of advanced data processing such as a computer. Say.

In one embodiment, the arithmetic processing means comprises:
Each time the information is acquired by the operation information acquisition unit or the water supply information acquisition unit, the date and / or time information at that time may be acquired and stored. By using such detailed operation information, it is possible to calculate various data relating to the use of the water supply / drainage equipment. For example, the life of the drainage pumping device is predicted, and suspicious use of the water supply / drainage equipment (for example, abnormal operation). It is also possible to detect such as when it has not been used for a long period of time. As a result, a wide range of applications are conceivable, such as improving the maintainability and manageability of water supply / drainage systems and providing security.

Further, for example, when the motor of the drainage pumping device or the motor of the crushing device is replaced with a new one, it is preferable to reset the counting result by the operation information acquisition device or the water supply information acquisition device. The reset means may be further provided.

Further, when the above-mentioned notifying means is a display means, it is preferable that the user can easily confirm this display, but on the other hand, it is necessary to consider so as not to spoil the appearance of the design. is there. Therefore, it is preferable that the notification means is installed inside a cabinet that surrounds the drainage pumping device, and that the cabinet is provided with a door body that can be opened and closed at a position where the notification means can be visually recognized when opened.

The drainage pumping apparatus or the water supply / drainage system according to the present invention is particularly suitable for a structure in which the water supply / drainage facility is a toilet bowl.

Furthermore, the drainage pumping device or the water supply / drainage system according to the present invention may be provided alone, but a plurality of such drainage pumping devices or water supply / drainage systems are provided to monitor the usage status of a plurality of water supply / drainage facilities. It can be applied to such a water supply and drainage facility monitoring system. Such a system is very useful for efficiently managing a large number of drainage pumping devices or water supply / drainage systems in, for example, public toilets, toilet booths in large-scale retail stores such as department stores.

Further, in such a water supply / drainage equipment monitoring system, not only is the usage status of the water supply / drainage equipment monitored,
It may be configured to further include auxiliary monitoring means for monitoring the usage status of a private room in which the water supply / drainage equipment is installed, or a booth having a plurality of private rooms. According to this configuration, it is possible to obtain more detailed information that the private room in which the water supply / drainage equipment is installed was used but the water supply / drainage equipment was not used, so it is only necessary to improve the maintainability / management of the water supply / drainage equipment. Not only that, it can be applied to a wide range of purposes such as checking the usage status of facilities.

BEST MODE FOR CARRYING OUT THE INVENTION Specific embodiments of a drainage pumping apparatus according to the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a drainage pumping apparatus according to one embodiment of the present invention (hereinafter referred to as "first embodiment"). The drainage pumping device 1 includes a storage tank 10 having a substantially rectangular parallelepiped shape as an outer box, and has a drainage inlet 11 on a side surface, a ventilation hole 12 on an upper surface, and a discharge opening 13 on another side surface. is doing. Inside the storage tank 10, there are provided a pressure feeding unit 20 as the pressure feeding unit and a crushing unit 30 as the crushing unit.

The pumping section 20 includes a pump motor 21, an impeller 22 driven to rotate by the pump motor 21,
The impeller 22 is provided inside and a pump chamber 23 having a suction port opened downward. The pressure feed pipe 15 connected to the discharge port on the side of the pump chamber 23 is discharged to the outside of the storage tank 10 through the discharge port 13. Has been derived.

The crushing unit 30 passes through a crushing motor 31, a liquid such as water or urine, and a screen 32 for temporarily holding solid matter, and a crushing motor 31 located in the screen 32 and rotated by the crushing motor 31. And a driven cutter 33. Drainage containing solid matters flows into the screen 32 through the drainage pipe 14 connected to the drainage outlet of the water supply and drainage facility such as a toilet bowl.

Further, inside the storage tank 10, a water level sensor 16 that moves up and down according to the water level of the accumulated drainage is installed, and the output of this water level sensor 16 is connected to a water level detecting section 40. The electric circuit section includes the water level detecting section 40, the control section 41, the pump motor driving section 42, the crushing motor driving section 43, the first operation number counting section 44 and the second operation number counting section 45 as the operation information acquiring means. , Comparison section 4
6, a threshold memory 47, a notification unit 48, etc.
8 includes a display unit 481 that visually notifies information and a sound generation unit 482 that auditorily notifies information. As will be described later, since the notification unit 48 provides information to the user and calls the user's attention, for example, when the water supply / drainage facility is a toilet bowl, the toilet bowl is installed. It is preferable that it is provided above the floor of the toilet room.

Next, an example of the operation of the drainage pumping device 1 when the water supply / drainage facility is a toilet bowl will be described.
When water is flushed after use in a toilet bowl (not shown), the solid matter flows into the storage tank 10 together with the water through the drainage pipe 14. The solid matter in the inflowing wastewater is temporarily locked by the screen 32, and the water mixed with urine passes through the screen 32 and falls into the storage tank 10. The water level in the storage tank 10 rises due to the inflow of the waste water, and when the water level becomes equal to or higher than the predetermined water level L, the water level detection unit 40 outputs a water level arrival signal to the control unit 41.

Upon receiving the water level arrival signal, the control unit 41 first activates (turns on) the pump motor 21 via the pump motor drive unit 42. As a result, the impeller 22 rotates to start the pump operation as the pressure feeding unit 20, so that the human waste stored in the storage tank 10 is sucked into the pump chamber 23, and then externally (for example, drainage vertical) through the pressure feeding pipe 15. For example, it is forcibly sent to a pipe). The control unit 41 also activates the crushing motor 31 via the crushing motor driving unit 43 at the same time as, or before or after the activation of the pump motor 21. As a result, the cutter 33 also rotates, crushes the solid matter retained on the screen 32, and drops it into the storage tank 10.

Once the motors 21 and 31 are turned on, the control unit 41 keeps them on for at least a predetermined time regardless of the presence or absence of the water level arrival signal. This is because it is not preferable that the motors 21 and 31 are repeatedly turned on / off in a short time. If there is a water level arrival signal immediately before the above minimum predetermined time elapses (that is, the predetermined water level L
If not below), the ON state is further extended. As described above, if the pump operation causes the drainage pumping and the water level becomes lower than the predetermined water level L, the pump motor 2 will be operated after the minimum predetermined time has elapsed.
The operation of No. 1 is stopped, and the operation of the crushing motor 31 is stopped at the same time or with a slight delay.

The operation method of the pressure feeding section 20 and the crushing section 30 is not limited to the above-mentioned procedure, and various modes can be adopted. For example, when the drainage from the toilet bowl is started, the crushing motor 31 is first started, and then the pump motor 21 is started, while at the end of the operation, the crushing motor 31 is first stopped and then the pump motor 2 is started.
1 may be stopped. Further, it is not always necessary to use the detection signal from the water level sensor 16 for controlling the operation.

The ON / OFF signals of the pump motor 21 and the crushing motor 31 as described above are given to the first operation number counting section 44 and the second operation number counting section 45, respectively. The units 44 and 45 count the number of times of each ON operation. First and second operation number counting units 44, 45
Can reset the count value by a predetermined operation or instruction from the outside. Normally, the count value is reset at the start of use of the drainage pumping device 1, and the motors 21 and 31 are replaced with new ones. Each will be reset. Therefore, the first and second operation number counting unit 4
The count values of 4 and 45 are increased each time the motors 21 and 31 are turned on from the state where the motors 21 and 31 are hardly used.

The first and second operation number counting units 44, 4
In No. 5, if the count value up to that point is lost due to a power failure, etc., the operation described below cannot be performed. Therefore, at least the count value should be backed up with an auxiliary power source such as a battery, or saved in a non-volatile memory. It is preferable to adopt a configuration.

The counting results by the first and second operation number counting sections 44 and 45 are sent to the display section 481 and displayed as numerical values. Therefore, the user, the person in charge of maintenance, and the like can see how many times each of the motors 21 and 31 has been used by looking at the numerical values displayed on the display unit 481.

At the same time, the count values are also given to the comparing section 46. Normally, the duration of one ON state of the motors 21 and 31 is almost fixed, so the motors 21 and 3 are
It is possible to pre-estimate the number of times of use in which the probability of occurrence of failure becomes high in consideration of 1 and the durability time of the movable part associated therewith. A predetermined threshold value based on such an estimation is set in the threshold value memory 47 in advance. Two motors 21,
Since 31 does not always have the same specifications, both thresholds are not always the same. Specifically, for example, if the motor life is 10,000 hours as a result of a durability test or the like, and a margin is given, 90% of the motor life is given to issue a warning of failure for 9000 hours. If the time is 2 minutes on average, 270,000 is set as the threshold value. Of course, it goes without saying that this numerical value is an example and can be changed appropriately.

The comparing section 46 constantly compares the count value with the threshold value, and when the count value reaches the threshold value, issues a drive command to the sound generating section 482. Upon receiving this command, the sound generation unit 482 alerts the user by emitting a predetermined warning sound. The sound at this time may simply be a buzzer sound, or may be a sound using synthetic speech or the like.

When the sound generating unit 482 is installed in the toilet room, it is desirable that the warning sound be generated while the user is in the toilet room. Therefore, instead of continuously producing sound, when it is detected that there is a person in the toilet room (for example, when a seat sensor is installed in the toilet seat of the toilet, when seating is detected) (2) A more preferable method can be adopted to call the user's attention, such as sounding a buzzer.

The user who receives such a warning notification can contact the person in charge of maintenance and repair to request repair such as replacement of the motor. In addition, as described above, the display unit 4
Since the count value of the number of times of use of the motors 21 and 31 is also displayed in 81, the user or maintenance person can confirm that the number of times of use of the motor is surely close to the end of life. You can also check. Motor 2
When the 1 and 31 are replaced with new ones, the reset operation as described above is performed and the count value is returned to zero.
When the service lives of 1 and 31 are approaching, the warning can be issued similarly.

The notification level may be set to a plurality of levels. That is, a plurality of thresholds for comparing the count values may be provided, and notification may be made to draw more attention each time the thresholds are exceeded. In the first embodiment, the number of times the motors 21 and 31 are actuated is counted, but the actuation times may be integrated, and a warning may be issued when the integrated value exceeds a predetermined value. . Furthermore, the first and second operation number counting units 44 and 45 may be mechanical counters that count pressing operations, instead of electrical counters.

FIG. 2 is a block diagram of a drainage pumping apparatus according to another embodiment of the present invention (hereinafter referred to as "second embodiment"). In FIG. 2 (and also in the subsequent drawings), components that are the same as or correspond to those in FIG. 1 are given the same reference numerals, and descriptions thereof are omitted unless otherwise required.

The drainage pumping apparatus 1 of the second embodiment is largely different from the first embodiment in that the motor 21 is shared by the pumping section 20 and the crushing section 30, and the operation number counting section 44 is used. The output of is processed by the arithmetic processing unit 50.

That is, in this drainage pumping device 1, the cutter 33 of the crushing unit 30 and the impeller 22 of the pumping unit 20 are coaxially driven to rotate by the only motor 21. Therefore, as a matter of course, only one operation number counting unit 44 for counting the number of ON operations of the motor 21 is required. The arithmetic processing unit 50 and the data storage unit 51 are provided to perform more sophisticated data processing than the device of the first embodiment, and are realized by executing predetermined software on a personal computer, for example. Can be done. Although the operation number counting unit 44 is provided separately from the arithmetic processing unit 50 in FIG. 2, the operation number counting unit 44 is provided.
The function of can be incorporated in the arithmetic processing unit 50.

The operation of this drainage pumping apparatus 1 is as follows. Normally, the motor 21 is turned on when a toilet bowl, which is a water supply / drainage facility, is used. Therefore, as shown in FIG. 3, for example, the on-operation signal of the motor 21 is counted at non-constant intervals with the passage of time. It is input to the unit 44 and the arithmetic processing unit 50. The operation number counting unit 44 counts the number of times the motor 21 is used each time the ON operation signal is input as described above. On the other hand, the arithmetic processing unit 50 receives the count value and also obtains the time (for example, t1, t2, t3, etc. in FIG. 3) and the date when the ON operation signal is given from the built-in clock and calendar. Are stored in the data storage unit 51. As a result, the usage history of the drainage pumping apparatus 1 is recorded in detail in the data storage unit 51.

Of course, also in the second embodiment, the first
Similar to the embodiment, it is possible to display the count value corresponding to the number of times the motor 21 has been used and to give a warning when the life is approaching. In addition to that, the usage stored in the data storage unit 51 is used. Various information can be provided using the history. For example, it is possible to calculate and output the number of times of use of the motor 21 for each predetermined period such as one day, one week, and one month. In addition, it is possible to calculate the frequency of use of the motor 21 divided for each time zone such as morning, daytime, night, and midnight. Therefore, not only the warning notification based on the number of times the motor 21 is used but also the prediction of the time when the motor 21 will reach the end of its life can be performed.

In order to perform such more advanced maintenance and management, it is not enough to simply confirm the data processing result in the vicinity of the drainage pumping device. Therefore, the data to be or stored in the data storage unit 51 may be sequentially or regularly sent to a predetermined maintenance / management company or the like using a communication line such as the Internet. In this way, the maintenance / management company can not only know the timing of the maintenance and inspection of the toilet equipment, but also check the safety of the elderly living alone by monitoring the frequency of use of the toilet in the residence, for example. It can also be used for security management, etc., and has a very wide range of applications.

In the above two embodiments, the number of times of use of the pumping section and the crushing section is counted in order to monitor the usage status of the drainage pumping apparatus, but the drainage pumping apparatus is used as a part of the water supply / drainage system including the water supply / drainage equipment. If captured, the usage status of the drainage pumping device can also be monitored as a result by checking the usage status on the water supply side. FIG. 4 is a configuration diagram showing a toilet system which is an example of such a water supply / drainage system (hereinafter referred to as “third example”).

That is, in this toilet system, flush water can be supplied to the toilet bowl 2 by rotating the operation lever 301 provided on the side surface of the low tank 3, but the rotation operation of the operation lever 301 is detected. In order to do so, an operation detection unit 60 including a mechanical switch is provided. Normally, when flush water is flowed from the low tank 3 to the toilet 2, the pumping section and the crushing section of the drainage pumping apparatus 1 should operate. Of course, there may be cases where water flows from the bucket or the like into the bowl of the toilet 2 without using the low tank 3, but this is considered to be a very rare case. The number of pumping operations and the number of crushing operations are almost the same. Therefore, by giving a detection signal from the operation detection unit 60 to the operation number counting unit 44 described in the first and second embodiments, the same display and warning notification as described above can be performed.

Further, in any of the above embodiments, when the display unit 481 is provided in the drainage pumping apparatus 1, it is preferable to have a structure as shown in FIG. FIG. 5 is a front view of the main part in the toilet room. In order to improve the appearance, the drainage pumping device 1 arranged at the rear of the toilet 2 is housed in the cabinet 4 and is invisible to the user of the toilet. An opening 4a is formed in a part of the front surface of the cabinet 4, and the opening 4a can be opened and closed by a door body 4b. When the door body 4b is opened, a part of the drainage pumping device 1 can be seen inside the opening 4a, and there, a display panel 61 as a display unit 481 and a reset switch 62 for resetting the count value. Is provided. With such a configuration, the number of times the drainage pumping device 1 is used can be known at any time when necessary without impairing the appearance of the toilet room.

Although each of the above-described embodiments has a configuration for monitoring the use condition of one drainage pumping device, for example, in a toilet booth having a plurality of toilet private rooms, a plurality of drainage pumping devices are simultaneously monitored. Need to do. It would be convenient if not only to monitor the drainage pumping device but also to monitor the usage status of the toilet.

FIG. 6 shows an example of the construction of such a toilet monitoring system. In this example, the toilet booth is provided with three toilet private rooms 5a, 5b, 5c, and the low tank 3a installed in each toilet private room 5a, 5b, 5c,
3b and 3c include the operation detection units 60a and 60 as described above.
b, 60c are provided respectively, and toilet bowls 2a, 2b, 2c
Is used as a usage status detection signal and is connected to a data processing device (not shown). Although not shown in this figure, each toilet is equipped with a drainage pumping device as in FIGS. 4 and 5. However, the drainage pumping device may be shared by a plurality of toilet bowls.

On the other hand, in order to detect the use status of each toilet private room 5a, 5b, 5c, as an example of auxiliary monitoring means,
Lock detection unit 7 that detects locking of the doors 6a, 6b, 6c
a, 7b, 7c are provided. Normally, when a toilet private room is used, it is considered that the door of the toilet private room is closed and locked, so that the lock detection units 7a, 7
The output signals of b and 7c can be used as a usage status detection signal of each toilet private room. Of course, in order to monitor the usage status of each toilet room, a person detecting means using an infrared sensor or the like may be used instead of the lock detecting section.

With such a configuration, for example, a signal as shown in FIG. 7 can be obtained. The following can be understood based on this signal. For example, in the toilet private room 5a, after a person has entered the room, the washing water is operated three times. In addition, it is estimated that the person who first entered the toilet private room 5b did not use the toilet because he / she did not perform the operation of flowing the wash water although he / she entered the room. The toilet private room 5c has not been used even once during this period.
In this way, by not only monitoring the usage status of the drainage pumping device but also the usage status of the toilet,
Various data can be obtained. Based on such data, it is possible to make a renovation plan such as a shortage or excess of private toilet rooms.

The above embodiment is merely an example of the present invention, and it is apparent that appropriate changes and modifications can be made within the scope of the present invention.
