Abstract

(57) [Summary] (with amendments) [Purpose] If the blower, etc. that supplies air to the septic tank breaks down, the condition can be seen at a glance. [Structure] An alarm lamp 7 is used that is turned on or off by a relay circuit or a photocoupler when it detects that the current has stopped flowing in the air supply source 3 of the purification device that supplies air into the septic tank. It is designed to be installed in a conspicuous place to immediately notify of abnormalities in the air supply source.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention allows the septic tank to be used when the septic tank air supply source fails. Trouble list for purifier air supply source to notify when the air supply has stopped. This relates to display devices.

0002

[Conventional technology]

The septic air supply that supplies the septic tank is generally installed outdoors and covered. They are usually completely covered by It is normal for this to happen.

0003

[Problem that the idea aims to solve]

The purifier air supply source uses an aerobic bath to decompose the waste that enters the septic tank. This air supply is necessary because it supplies air to increase the activity of the cells. If the supply shuts down, for example due to a ruptured diaphragm, the The bacteria will die and the purification function will stop, so it is important to discover the malfunction early. However, as conventional septic tanks do not have any such measures in place, it is difficult to detect malfunctions. It was often left unattended.

0004 This invention installs warning lamps in conspicuous locations to prevent purification equipment from being activated. To make it easier to discover faults in the air supply source and to detect fault conditions immediately. It is.

[0005]

[Means to solve the problem]

The present invention, as a means to solve the above problem, actuated or actuated by the operation of a relay circuit or light emitting diode with respect to the source circuit. A phototransistor is provided to stop the current from being supplied to the air supply source. directly by the relay circuit or the phototransistor etc. Indirectly turn on or turn off warning lamps installed in conspicuous places. It adopts a structure that allows for

[0006]

[Effect]

In the invention of claim 1, when the air supply source fails, the current flowing through the relay circuit stops flowing. As a result, the normally open contact of the relay closes and the alarm lamp lights up. The alarm lamp is installed in a conspicuous location, so the air supply source for the purifier is Failures can be detected immediately.

[0007] In the invention of claim 2, when the air supply source fails, the group of diodes provided in series Since current will no longer flow through the LED, the light emitting diode that was emitting light during normal operation will be Direct current no longer flows, so the phototransistor in the alarm circuit is turned off. A warning lamp placed in a conspicuous place immediately turns off. Do it like this indicates a failure in the purifier air supply.

[0008]

【Example】

The present invention will be described below with reference to embodiments shown in the drawings.

[0009] First, the first embodiment shown in FIG. 2 will be explained. 2 is a power supply circuit for a purifier air supply source 3 such as a compressor or pump that supplies It is a current power source. 5 is an abnormality detection circuit, which has a relay coil 4 provided in the power supply circuit 1. It is also provided with a relay circuit 4'. 6 is a normally closed relay installed in the abnormality detection circuit 5 The contact is designed to close when current no longer flows through the relay coil 4. 7 is An alarm lamp installed on the wall of the toilet or the kitchen, 8 indicates the power of the alarm lamp 7. These are power source batteries, and both are provided on the abnormality detection circuit 5. Also, on the abnormality detection circuit 5 is installed in parallel with the normally closed contact 6, and whether current is flowing through the abnormality detection circuit 5. A normally open check switch 9 is provided to check whether the Also, Figure 1 shows the An example is shown in which the warning lamp 7 is installed outdoors, and 10b in the figure is an outlet.

0010 Next, the operation of the embodiment shown in FIG. 2 will be explained. When the air supply source 3 is activated, the air A is blown into the septic tank. When this air supply source 3 is operating normally , the alarm lamp 7 does not light up, but if the air supply source 3 stops due to a disconnection, etc. , because current no longer flows through relay circuit 1 and no current flows through relay coil 4. , the normally closed contact 6 of the abnormality detection circuit 5 closes. Therefore, no current was flowing until now. A current flows through the abnormality detection circuit 5 using the battery 8 as a power source, and the alarm lamp 7 lights up. Na Oh, is there a drop in the voltage of the battery 8 while the air supply source 3 of the purifier is operating? If you want to check the alarm lamp 7, press the inspection switch 9. Depending on the situation, it can be determined whether or not there is the ability to light up the alarm lamp 7. Ru.

[0011] Next, explaining the second embodiment of FIG. 3, 12' is a purifying device such as a compressor. It has 12 groups of diodes connected in series to the power supply circuit 11 of the air supply source 3. The diode circuits 13 and 13' are connected in parallel to the diode circuit 12'. A photocoupler light emitting diode 14 is provided in the rectifier circuit 13. Furthermore, a phototransistor as a photo-receiving element of the photocoupler is connected to the AC power source 2. The alarm lamp 7 blinks depending on whether the transistor 16 and the phototransistor 16 are turned on or off. The alarm circuits 15, 15' are connected to the power supply circuit 1. 17 is the alarm circuit 15, 15' It is a normally closed switch that opens and closes, and when the switch 17 is opened, the alarm circuits 15 and 15' are activated. The current is cut off and the alarm lamp 7 goes out.

0012 Next, the operation of the embodiment shown in FIG. 3 will be explained. Supplying air to a septic tank (not shown) If the air supply source 3 of a purification device such as a compressor stops due to a disconnection, etc., the Since the potential difference between both terminals of the diode circuit 12' becomes zero, the light emitting diode of the photocoupler Since the ode 14 no longer emits light and the phototransistor 16 no longer operates, the No current flows to the input side of the current circuit 13. At this time, the resistance C of the alarm circuit 15' Since there is no longer a potential difference between both terminals, the alarm lamp 7 goes out and the compressor It can be seen that the drive source 3 of the purifying device such as the sanitary cleaner has failed.

[0013] FIG. 4 is an embodiment showing a modified usage mode of the photocoupler shown in FIG. A transistor 20 is connected to the collector side of the transistor 16, and the alarm lamp 7 is connected to the collector side of the transistor 16. It is connected to the collector side of the transistor 20.

[0014] In the embodiment shown in FIG. When actuated accordingly, the transistor 20 is turned off and the alarm lamp 7 is extinguished. Also, if the air supply source 3 fails and the phototransistor 16 stops operating, an alarm will be activated. 7 lights up.

[0015]

[Effect of the idea]

According to this invention, the air supply source such as the compressor that supplies air to the septic tank has malfunctioned. When the current stops flowing in the power circuit, the alarm lamp will turn on or off, and this alarm will be activated. The flashing state of the warning lamp can be easily known, for example, in the bathroom or kitchen. Also the main idea As proposed, when the deviation in potential difference is detected using a photocoupler, the phototransistor It is possible to extract a sudden change in the base current as a large change in the collector current. This makes it extremely easy to discover failures.
