Description

  The present invention relates to a cleaning water supply device such as a toilet and a system for monitoring an operation abnormality of a flush valve in the cleaning water supply device.

  Toilets used by patients are installed in isolated rooms of psychiatric hospitals. Contained patients sometimes take unexpected actions, such as unnecessarily operating the wash button. In the case of flush valve type toilets, the wash water is supplied directly from the water pipe every time the wash button is operated. If wash water is supplied beyond the drainage capacity of the toilet, an overflow accident may occur. is there.

  For example, the cleaning water supply device described in Patent Document 1 is configured such that when a patient operates a cleaning button, a call lamp installed in a nurse station is turned on, and a nurse or the like performs a predetermined operation to supply cleaning water. Has been. This is trying to avoid unnecessary consumption of washing water.

JP 2004-300908 A

  However, in the configuration described in Patent Document 1, since the cleaning water is not supplied unless the nurse or the like performs a predetermined operation, the patient is restricted by the nurse and has a hygiene problem. Also, if the patient frequently operates the washing button and performs the washing water supply operation each time, the risk of an overflow accident cannot be avoided after all. Nurses and the like are required to judge the situation each time for such patient's actions, which increases work burden and decreases efficiency.

  There have been proposals to install an optical sensor in the toilet to detect an abnormal rise in the water level and to prevent an overflow accident, but either provide a toilet equipped with a waterproof optical sensor unit or an existing toilet The construction of adding such an optical sensor unit to the toilet is expensive. In addition, there is a risk that an accommodating patient who takes unexpected actions may contaminate or destroy the optical sensor unit.

  The present invention has been made to solve at least a part of the above-described problems, and an object of the present invention is to appropriately monitor an abnormal operation of a cleaning button by a patient at a low cost and without a risk of contamination. The purpose of this is to prevent toilet overflow accidents, reduce the burden on nursing work, and improve efficiency.

  In order to solve at least a part of the above-described problems, the present invention can take various modes listed below.

A first aspect of the present invention is a cleaning water supply device that supplies cleaning water to a toilet bowl,
Box and
A cleaning button provided on the front of the box;
A first valve provided inside the box and opened by operating the washing button;
A pipe line provided inside the box and supplying the flush water to the toilet;
A flush valve provided inside the box and capable of opening and closing the conduit;
A working water supply path that is provided inside the box and that supplies working water that opens the flush valve when the first valve is opened;
A flow sensor that is provided in the working water supply path and outputs a detection signal when working water of a predetermined flow rate or more flows through the working water supply path;
A control unit that is provided inside the box and receives the detection signal;
The control unit outputs an abnormality detection signal indicating an abnormal operation of the flash valve when at least one of the time and the number of times of receiving the detection signal satisfies a predetermined condition.

  In the first aspect of the present invention, the predetermined condition is variable.

  1st aspect of this invention WHEREIN: The 2nd valve | bulb which is connected to the said control part and can open and close the said operating water supply path is further provided, and the said 2nd valve is opened and closed by remote control via the said control part It is made possible.

According to a second aspect of the present invention, there is provided a cleaning water supply device that supplies cleaning water to a toilet, a control panel that is installed in a place different from a living room provided with the toilet and includes a notification unit, and a control unit. A monitoring system,
The washing water supply device includes:
Box and
A cleaning button provided on the front of the box;
A first valve provided inside the box and opened by operating the washing button;
A pipe line provided inside the box and supplying the flush water to the toilet;
A flush valve provided inside the box and capable of opening and closing the conduit;
A working water supply path that is provided inside the box and that supplies working water that opens the flush valve when the first valve is opened;
A flow sensor that is provided in the working water supply path and outputs a detection signal when working water having a predetermined flow rate or more flows through the working water supply path;
The control unit outputs an abnormality detection signal indicating an abnormal operation of the flash valve when at least one of the time and the number of times of receiving the detection signal satisfies a predetermined condition,
The notification unit performs a notification operation based on the abnormality detection signal.

  In the second aspect of the present invention, the predetermined condition is variable by remote operation from the control panel.

  2nd aspect of this invention WHEREIN: The said washing water supply apparatus is further equipped with the 2nd valve | bulb which is connected to the said control part and can open and close the said working water supply path, The said 2nd valve | bulb is the said control panel. It can be opened and closed by remote operation.

  In the second aspect of the present invention, the control unit holds the date and time when the abnormality detection signal is output and the predetermined condition as a record.

  According to the first aspect of the present invention, for example, when the patient operates the cleaning button of the cleaning water supply device, the cleaning water is supplied as usual. Can also be avoided.

  In addition, since an abnormality detection signal can be output only when an excessive supply of washing water that meets conditions set appropriately in advance according to the drainage capacity of the toilet bowl, it is possible to generate an overflow accident. It can be prevented in advance.

  Since the flow sensor is provided inside the box, it is possible to avoid a possibility that the flow sensor is damaged by an unexpected action of a patient or the like. In addition, since it is not necessary to perform waterproofing on the flow sensor itself, the cost of components is suppressed.

  By configuring the second valve to be remotely opened and closed, for example, when an abnormal signal is detected, an operation for immediately closing the second valve can be performed. As a result, the supply of working water to the flush valve is cut off, and the supply of flush water to the toilet is interrupted. As a result, unnecessary washing water can be prevented from being consumed in a situation where an abnormal operation is detected.

  According to the second aspect of the present invention, the same effect as in the first aspect can be obtained. For example, when a control panel is installed in a nurse station, an abnormality is automatically notified only when an excessive supply of cleaning water that matches the conditions set in advance according to the condition of the patient and the nursing environment is performed. Nurses and the like can perform response measures without being forced to make difficult situation decisions. This reduces the burden on nursing work and improves work efficiency. This effect becomes more pronounced as the number of rooms increases.

  When a nurse or the like receives an abnormality notification and immediately closes the second valve, the supply of working water to the flush valve is cut off and the supply of flush water to the toilet is interrupted. Nurses and the like can calmly check the situation while preventing unnecessary washing water from being consumed.

  Since the date and time when the abnormality detection signal is output and the determination condition are stored as a record, it is easy to grasp the behavior tendency of the patient, which can be used for reviewing the nursing plan and the like. This effect becomes more prominent as the number of patients increases.

It is the general-view figure which looked at the washing water supply device concerning the present invention from the inside of the isolation room. It is the general-view figure which looked at the washing water supply apparatus of FIG. It is a flowchart which shows operation | movement of the washing water supply apparatus of FIG. It is a block diagram which shows the structure of the monitoring system which concerns on this invention.

  A cleaning water supply apparatus according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

  The washing water supply apparatus 1 of this embodiment is installed in a hospital room that accommodates a patient that needs to be isolated, for example, in a psychiatric hospital. A stainless steel toilet 2 used by the patient is installed in the hospital room. As shown in FIG. 1, the washing water supply device 1 includes a metal box 3, and is installed so that the front surface 3 a is exposed on the inner wall of the hospital room.

  Only a stainless steel hand-washing machine 4 and a washing button 5 are provided on the front surface 3 a of the box 3. A water outlet 4 a is formed in the upper part of the hand-washing machine 4, and a water outlet 4 b is formed in the lower part of the hand-washing machine 4. When the patient operates the washing button 5, washing water is supplied to the toilet 2 and washing is performed, and washing water for hand washing is supplied from the outlet 4a. By minimizing the number of members exposed in the patient's room, the patient's unexpected destruction is prevented.

  As shown in FIG. 2, all members such as piping for supplying cleaning water are accommodated inside the box 3 located outside the hospital room. Specifically, an on / off valve 5a (corresponding to the first valve of the present invention), a flush valve 6, a working water supply path 7 (see FIG. 4), a flow sensor 8, an electromagnetic valve 9, and a control unit 10 are accommodated. ing. Nurses and maintenance managers can operate and maintain these members without entering the hospital room.

  The on / off valve 5a is connected to a cleaning button 5 provided on the front surface 3a of the box 3, and controls the hydraulically operated flush valve 6 as will be described later.

  The flush valve 6 includes a working water inlet 6a, an inlet-side pipeline 6b, an outlet-side pipeline 6c, a toilet-side pipeline 6d, a throttle valve 6e, and a branch pipeline 6f. The outlet side pipeline 6c is connected to the toilet 2 via the toilet side pipeline 6d. A branch pipe 6d branched from the outlet side pipe 6c is connected to the water outlet 4a of the hand washing device 4. The throttle valve 6e is for adjusting the flow rate of the wash water flowing out from the water outlet 4a via the branch line 6f. A water distribution pipe 4 c is connected to the drain port 4 b of the hand washing device 4.

  The working water supply path 7 includes a first pipe 7a, a first joint 7b, a second pipe 7c, a third pipe 7d, a second joint 7e, a fourth pipe 7f, and a fifth pipe 7g. Yes. The on / off valve 5 a, the flow sensor 8, and the electromagnetic valve 9 also constitute a part of the working water supply path 7.

  The first pipe line 7 a is for taking in the working water under water pressure from the inlet side pipe line 6 b of the flash valve 6. A first conduit 7a, an electromagnetic valve 9, and a second conduit 7c are connected to each end of the T-shaped first joint 7b. The second pipeline 7c is connected to one end of the third pipeline 7d through the flow sensor 8 and the on / off valve 5a. The other end of the third pipe line 7d is connected to one end of the second joint 7e. A fourth pipe line 7f and a fifth pipe line 7g are connected to the remaining end of the second joint 7e. The fourth pipeline 7 f is connected to the electromagnetic valve 9, and the fifth pipeline 7 g is connected to the working water inlet 6 a of the flash valve 6.

  When the patient in the hospital room operates the washing button 5, the on / off valve 5a is opened for a predetermined time, and the working water applied with water pressure from the inlet side pipe line 6b passes through the first pipe line 7a and the second pipe line 7c. take in. The working water is supplied to the working water inlet 6a via the third pipe 7d and the fifth pipe 7g, and the flush valve 6 is opened. The washing water is supplied from the inlet side pipe 6b to the toilet side pipe 6d and the branch pipe 6f via the outlet side pipe 6c, and the toilet 2 is washed and discharged to the hand washing machine 4.

  The flow sensor 8 is for detecting the flow rate of the working water flowing through the working water flow path 7. A flow path formed inside the flow sensor 8 is filled with a float including a magnet so as to be movable in the flow path. The flow sensor 8 is attached to the working water flow path 7 so that the flow path faces in the vertical direction, and the float is positioned at the lowest part in the movable range in a steady state. When the on / off valve 5a is opened and the working water flows through the working water flow path 7, the float is pushed up from the steady position by the water flow. A switch that can be displaced by a magnetic force is provided above the steady position. When the float rises to a position facing the switch, the switch is displaced by the influence of the magnet provided in the float, and the contact is connected.

  Therefore, by keeping the position of the switch away from the normal position of the float by a distance corresponding to the flow rate that requires detection, the contact point of the switch is connected when the predetermined amount of working water flows through the working water flow path 7, and the detection signal Can be output. The detection signal is transmitted to the control unit 10. In the present embodiment, the position of the switch can be adjusted according to the flow rate that requires detection.

  Instead of the switch that is mechanically displaced by the magnet provided in the float, a magnetic sensor that outputs a detection signal when a predetermined magnetism is detected may be provided. Even in this case, the flow rate of the working water that requires the output of the detection signal can be adjusted by adjusting the position of the magnetic sensor (the distance from the steady position of the float).

  The float type flow sensor 8 as in the present embodiment can be arranged at an arbitrary position in the working water flow path 7 on the condition that the flow path faces in the vertical direction. The flow sensor 8 can be replaced by any known detection method including an impeller type, and in that case, the installation position of the sensor is not particularly limited.

  The electromagnetic valve 9 normally closes the fourth conduit 7 f and is configured to be opened by operating an open button 9 a provided inside the box 3. Even when the electromagnetic valve 9 is opened, the working water is supplied from the inlet side pipe line 6b to the working water inlet 6a via the first pipe line 7a, and the flush valve 6 is opened so that the toilet 2 and the hand washing machine 4 are opened. Wash water can be supplied. The electromagnetic valve 9 is electrically connected to the control unit 10 and can be opened even when a control signal is input from the control unit 10.

  The control unit 10 includes a CPU (central processing unit), its peripheral circuits, and a timer. As shown in FIG. 4, the control unit 10 is capable of bidirectional communication with a remote control unit 12 provided in the nurse station 11. It is configured. Moreover, the control part 10 is comprised so that execution of the monitoring process shown by FIG. 3 is possible.

  When the patient operates the washing button 5 of the washing water supply device 1, the on / off valve 5 a is opened, the working water is supplied to the flush valve 6, the washing water is supplied to the toilet bowl 2 and the hand washing machine 4, and the flow sensor 8. Outputs a detection signal (step S11). The control unit 10 that has received the detection signal determines whether the detection signal has been continuously received for 30 seconds or more using a timer (step S12). The situation where the detection signal is continuously received for 30 seconds or more (Yes in step S12) corresponds to the case where the patient keeps pressing the washing button 5 unnecessarily. If such a state is left as it is, the wash water is supplied beyond the drainage capacity of the toilet bowl 2 or the hand-washing machine 4, which may lead to an overflow accident. In this case, the control unit 10 performs an abnormality detection process (step S13), and transmits an abnormality detection signal to the remote control unit 12 of the nurse station 11.

  If it is determined that the detection signal of the flow sensor 8 is not continuously output for 30 seconds or longer (No in step S12), the control unit 10 receives the detection signal from the flow sensor 8 five times or more per minute. It is determined using a timer (step S14). The situation where the detection signal is received five times or more per minute (Yes in step S14) corresponds to the case where the patient operates the washing button 5 unnecessarily frequently. If such a state is left unattended, there is a risk of an overflow accident, so the control unit 10 executes the abnormality detection process in the same manner as described above (step S13).

  If it is determined that the detection signal of the flow sensor 8 is not output five times or more in one minute (No in step S14), the control unit 10 subsequently receives the detection signal from the flow sensor 8 eight times or more in two minutes. It is determined using a timer (step S15). If the determination result is Yes, the control unit 10 executes an abnormality detection process (step S13). If the determination result is No, the control unit 10 determines whether a detection signal is received from the flow sensor 8 at least 11 times in 3 minutes. To determine (step S16). If the determination result is Yes, the control unit 10 executes an abnormality detection process (step S13). If the determination result is No, the control unit 10 determines whether a detection signal is received from the flow sensor 8 more than 20 times in 5 minutes. It judges using (step S17). If this determination result is Yes, the control unit 10 executes the abnormality detection process (step S13), and if it is No, the control unit 10 resets the timer (step S18) and waits for a detection signal from the flow sensor 8. The

  The determination conditions (combination of time and number of times) in steps S15 to S17 are all in a state where the patient operates the cleaning button 5 of the cleaning water supply device 1 unnecessarily frequently, that is, there is a risk of an overflow accident. It is set as something that can be considered. Although not explicitly shown in the flowchart of FIG. 3, if the detection signal is continuously received by the control unit 10 during each determination in steps S14 to S17 for 30 seconds or more, the monitoring process unconditionally goes to step S13. The process proceeds to anomaly detection processing.

  A control panel 13 is installed in the nurse station 11. The remote control unit 12 includes a CPU (Central Processing Unit) and its peripheral circuits. The remote control unit 12 may be provided as a part of a control board provided in the control panel 13 or may be realized as a function of application software that operates on a computer installed in the nurse station 11. The cleaning water supply device 1 arranged in an isolated hospital room and the like, and the remote control unit 12 and the control panel 13 arranged in the nurse station 11 constitute a monitoring system according to the present invention.

  As shown in FIG. 4, the control panel 13 includes a notification unit 14, an operation unit 15, and a condition setting unit 16. At least a part of the functions of the control panel 13 may be realized as a function of application software that operates on a computer installed in the nurse station 11.

  When the remote control unit 12 receives an abnormality detection signal from the control unit 10 of the cleaning water supply device 1, the notification unit 14 notifies the nurse or the like of the abnormality by at least one of a display and a voice. Any one of lamp lighting, abnormal message display, buzzer sound, voice message, or the like, or a combination of a plurality of them is notified. A nurse or the like can receive the notification and recognize that the patient is operating the cleaning button 5 (flash valve 6) of the cleaning water supply apparatus 1 abnormally.

  The operation unit 15 includes various buttons (including those displayed on the touch panel), and includes at least a notification stop button, a valve open button, and a monitoring process reset button. When the notification stop button is operated by the user, the notification operation of the notification unit 14 is forcibly stopped. When the valve opening button is operated by a nurse or the like, a control signal is transmitted from the remote control unit 12 to the control unit 10 of the cleaning water supply apparatus 1. The control unit 10 inputs the control signal to the electromagnetic valve 9 so that the electromagnetic valve 9 can be opened remotely. The monitoring process reset button is operated by a nurse or the like who has received an abnormality notification to resume the monitoring process after completing the countermeasure.

  The condition setting unit 16 is for remotely setting conditions for determination processing performed in the monitoring processing executed by the control unit 10, and includes various buttons (including those displayed on the touch panel). The The determination conditions of S12, S14 to S17 shown in FIG. 3 are merely examples, and can be arbitrarily changed according to various conditions such as the patient's condition, nursing environment, and toilet drainage capacity. For example, in the case of the determination of S12, the time for determining an abnormal operation can be changed as appropriate. Moreover, in the case of determination of S14 thru | or S17, the combination of the time and frequency | count which determine with abnormal operation can be changed suitably. Note that the number of determinations performed through S14 to S17 is not limited to four, and can be increased or decreased as appropriate through the condition setting unit 16. The setting input in the condition setting unit 16 is transmitted to the control unit 10 of the cleaning water supply apparatus 1 via the remote control unit 12 and reflected in the monitoring process to be executed.

  At least one of the control unit 10 of the cleaning water supply apparatus 1 and the remote control unit 12 of the nurse station 11 stores as a record the date and time when the abnormality detection process was executed and which determination result detected the abnormality. It is configured.

  When there are a plurality of isolated hospital rooms and the cleaning water supply device 1 is installed in each hospital room, the remote control unit 12 of the nurse station 11 can bidirectionally communicate with the control unit 10 of each cleaning water supply device 1. Connected to. In the nurse station 11, the usage status of each cleaning water supply device 1 is comprehensively monitored. In addition, it is good also as a structure which the remote control part 12 bears at least one part of the function of the control part 10. FIG.

  As described above, according to the configuration of the present embodiment, when the patient operates the cleaning button 5 of the cleaning water supply device 1, the cleaning water is supplied as usual, so that the patient is not restricted by a nurse or the like. Hygiene problems can also be avoided.

  Nurses are forced to make difficult situation judgments because an abnormality notification is automatically issued only when an excessive supply of cleaning water that meets preset conditions according to the patient's condition and nursing environment. The response action can be carried out. The burden on nursing work is reduced and work efficiency is improved. This effect becomes more pronounced as the number of rooms increases.

  In addition, since an abnormality is automatically notified only when an excessive supply of cleaning water that meets conditions set in advance in accordance with the drainage capacity of the toilet is performed, an overflow accident can be prevented.

  Since the flow sensor 8 responsible for a part of the monitoring process is provided in a portion of the box 3 that is disposed outside the hospital room, it is possible to avoid the possibility of the flow sensor 8 being damaged by an unexpected action of the patient. Further, since it is not necessary to perform waterproofing on the flow sensor 8 itself, the component cost is suppressed.

  At least one of the control unit 10 of the cleaning water supply apparatus 1 and the remote control unit 12 of the nurse station 11 stores the date and time when the abnormality detection process was executed and which determination result detected the abnormality as a record. Since it is configured, it is easy to grasp the patient's behavior tendency, which can be used for reviewing nursing plans and the like. This effect becomes more prominent as the number of patients increases.

  From the viewpoint of more reliably preventing an overflow accident, it is preferable that the washing water supply to the toilet 2 and the hand washing machine 4 by the washing water supply device 1 can be remotely stopped from the nurse station 11. A modification of the cleaning water supply apparatus 1 having such a configuration will be described below.
