However, when the alarm device is built in the electric device as described above, it is necessary to secure a space for the alarm device inside the electric device, in addition to the essential members of the electric device. And since the electric equipment which attached the alarm device in this way needs to give a new model name in order to distinguish from the electric equipment of the existing structure, it is complicated also in product management.
In addition, when an installation hole (communication between the inside of the electric device and the outside) is provided for the field-installed electric device as described above in an exposed state from the outer surface of the electric device, There is a risk of rainwater entering the device. For this reason, in the outdoor installation type electric equipment, it is necessary to perform waterproof curing on the mounting hole, and the mounting work of the alarm device is troublesome. Here, the alarm device may be configured separately from the electric device, but the installation location of the alarm device must be provided separately from the electric device, especially in the case of an outdoor alarm device. Installation work becomes troublesome. When the alarm device is installed outdoors, various problems may occur such as the alarm device being damaged by external physical force or the alarm buzzer being activated at night to generate inconvenient noise.
The present invention was devised in view of such points, and the object of the present invention is to make it possible to attach an alarm device to an electric device having an existing structure without modification, and to install the alarm device. To make it easier. Another object of the present invention is to provide an alarm device suitable for outdoor installation.

As means for solving the above problems, the alarm device of the first invention of the present invention is such that the main body plug provided in the alarm device body separate from the electric device is connected to the outlet of the original power source (original power outlet). The alarm installation work is completed. In this state, connect the attached plug of the electric device to the main body outlet provided in the main body of the alarm device, and attach the alarm device to the electric device. If the electric device has a plug attached to the existing structure, the alarm device can be attached without modifying the electric device itself.
And the alerting | reporting part of an alarm main body operate | moves based on the information from the abnormality detection apparatus which detects abnormality (for example, operation abnormality) of an electrically-driven apparatus, and emits a sound (for example, an electronic sound and voice guidance), a light, or an electrical signal. . That is, the alarm device may be configured such that the alarm device body directly notifies by sound or light, and is indirectly notified by another alarm device installed at a location different from the alarm device installation location by an electrical signal of the alarm device. It may be configured to. Moreover, the structure with which an abnormality detection apparatus is equipped with the main body of an alarm device may be sufficient, and the structure which utilizes the thing with which electric equipment is previously equipped may be sufficient.

Also, alarm of the first aspect of the present invention, the physical force of the barrier portion provided in the connection portion around the annex plug, by covering the annexed plug connected to the main body outlet, the supplementary plug connection status outside It is hard to receive. For this reason, in the externally arranged alarm device, it is possible to prevent or reduce breakage of the attached plug and disconnection of the attached plug due to external physical force.

Also, alarm of the second aspect of the present invention, in the alarm according to the first shot bright, the broadcast unit, is the sound generating device such as a buzzer or a speaker as the operable state by the sensor in detecting light . For example, in an alarm device arranged outdoors, the sound generator is operable in response to a sensor signal during the day when sunlight can be detected, but at night when sunlight cannot be detected. It is inoperable because it cannot be received. For this reason, it is possible to prevent or reduce inconvenient noise generation such as the operation of a sound generator at night in an alarm device installed outdoors.

In the third aspect of the present invention, at least one pair of the same shape of the original power outlets is arranged in parallel at the lower part of the projecting portion that projects in the horizontal direction with respect to the installation surface. The alarm device is the alarm device according to the first or second invention, and even if another plug satisfying the insulation standard is connected to one of the original power outlets, the other plug is obstructive. However, it has a width dimension that can be connected to the other original power outlet different from the one.

And the alarm device is the structure which provided the clearance gap (clearance L4) between the at least one surface of the front and back, and the installation surface in the connection state. The alarm device has a protruding portion formed on the surface thereof, and the protruding height dimension L5 of the protruding portion is set to be larger (higher) than the clearance L4. And at least one of an alerting | reporting part and a sensor is arrange | positioned on the alarm device surface. When the alarm device tries to be inserted into the main power outlet from below with the back surface facing the installation surface, the protrusion does not face the installation surface and can be connected to the main power outlet. On the other hand, if the alarm device is to be inserted into the original power outlet from below with its surface facing the installation surface, the protruding portion having a protruding height dimension L5 larger than the clearance L4 is obstructed and cannot be inserted.
For this reason, the alarm device must be connected to the main power outlet with its back face facing the installation surface, and the alarm section on the alarm device surface is visible, or the sensor on the alarm device surface is sunlight. Can be detected stably.

According to the first invention, the alarm device can be attached to an electric device having an existing structure without modification, and the installation work of the alarm device can be simplified.
Further , according to the first invention, since the attached plug in the connected state is hardly subjected to external physical force, an alarm device suitable for outdoor installation can be provided. According to the second invention, it is possible to provide an alarm device suitable for outdoor installation by preventing or reducing the occurrence of inconvenient noise. According to the third aspect of the present invention, an alarm device suitable for outdoor installation can be provided by having a configuration corresponding to a multi-port power supply for outdoor installation.

The best mode for carrying out the present invention will be described below with reference to FIGS.
FIG. 1 is a schematic diagram of the main power source, the blower, and the entire alarm device, and FIG. 2 is a perspective view of the main power source when the alarm device is connected as viewed from below.
The blower 40 is a field-installed electric device that supplies air to a septic tank (not shown) for wastewater treatment. The blower 40 is provided on the outdoor wall 16 with its associated plug 2 (also referred to as blower-attached plug 2). In this configuration, power is supplied from the original power supply 10. The main power supply 10 is a two-port type for outdoor installation, which has a rainproof overhanging portion 14 projecting in the horizontal direction with respect to the installation surface 16a and a pair of original power outlets 15 and 15 (same type) arranged below the projection. Power supply.

The alarm device 18 of the present embodiment is a separate body from the blower 40, and the installation work is completed by connecting the main body plug 12 provided on one side of the main body of the substantially rectangular alarm device 18 to the main power outlet 15. . In other words, the location where the original power supply 10 is disposed becomes the outdoor installation location of the alarm 18 as it is.
Furthermore, the alarm device 18 is connected to the main body outlet 4 provided on the other side of the main body, and the attachment work to the blower 40 is completed by connecting the blower-attached plug 2. The blower 40 is supplied with power from the main power supply 10 via the alarm device 18 connected to the attached plug 2. For this reason, the alarm device 18 can be attached to the blower 40 having the attached plug 2 as an existing structure without modifying the blower 40 in any way.

  The alarm 18 has a frame-shaped barrier 3 provided around the connection point (first connection surface 4a) between the main body outlet 4 and the blower-attached plug 2 and is connected to the main body outlet 4. It is the structure which covers one part or all. For this reason, even if the alarm 18 is externally installed, the barrier 3 serves as a protective barrier for the blower-attached plug 2, so that damage or disconnection of the blower-attached plug 2 due to external physical force can be prevented or reduced. it can. Moreover, since the barrier part 3 of the present embodiment is arranged so as to cover the blower-attached plug 2, it also serves as a protection against rain of the blower-attached plug 2.

On the surface 18a of the alarm device 18, there are an alarm lamp 8 and an optical sensor 6 that emits a signal by detecting light, and the sound generator 21 built in the alarm device 18 can be activated by the signal of the optical sensor 6. It becomes a state.
The warning light 8 and the sound generator 21 described above are notification units that operate based on information from an abnormality detection device described later that detects an abnormality (for example, an abnormal operation) of the blower 40. The alarm lamp 8 and the sound generator 21 may be configured to be operable by receiving power from the always-on power source 10 regardless of whether it is daylight or nighttime (regardless of whether sunlight can be detected or not). In addition, the sound generator 21 arranged outdoors is operable in response to a signal from the optical sensor 6 during the day (which can detect sunlight), but is light at night (which cannot detect sunlight). Since the signal from the sensor 6 cannot be received, it is possible to adopt a configuration in which the operation is disabled. With such a configuration, it is possible to prevent or reduce the occurrence of inconvenient noise due to the operation of the sound generator 21 at night in the alarm device 18 installed outdoors.
Here, the sound generating device 21 is a notifying unit that emits sound such as a buzzer that emits an electronic sound or a speaker that emits voice guidance, and the alarm lamp 8 is an LED (light emitting diode), neon lamp, incandescent lamp, halogen, or the like. It is a notification unit that emits light such as a lamp and a fluorescent lamp.

FIG. 3 is a schematic circuit diagram of the alarm device and the blower.
The alarm device 18 includes a CT-type current detector 31 that is connected to at least one of the power feeding cords 24 and 24 (each connected to the blower-attached plug 2) and detects the amount of current flowing through the power feeding cord 24. The alarm lamp 8 is in a state in which power can be constantly supplied from the main power supply 10 (see FIG. 2) via the power supply cords 24, 24, but the sound generator 21 is in a state in which power can be supplied only after receiving the signal from the optical sensor 6. It can also be set to (operation possible state). When the current detected by the current detector 31 is abnormal, the alarm lamp 8 is turned on (or flashes) by the detector 32, and the sound generator 21 is activated only when a signal from the optical sensor 6 is received (mainly during the day). It can also be activated. Note that the above configuration does not deny the operation of the sound generation device 21 at night, and it is a matter of course that the sound generation device 21 can be operated even at night with the sound generation device 21 in a state where power can be constantly supplied.

FIG. 4 is a schematic circuit diagram of another example alarm and blower.
Further, the alarm device 18 may have a configuration in which an energization interruption device 41 built in the blower 40 is used in advance instead of the CT type current detector. The power cut-off device 41 detects, for example, that an abnormal operation (partial reciprocating motion) has occurred in a diaphragm that performs a pump operation using an electromagnet, and cuts off the electrical conduction state of the blower 40 to stop feeding the electromagnet. It is a device to do. The alarm 18 and the blower-attached plug 2 communicate with each other by four cores, and the two cores thereof are detection codes 19 and 19 that communicate between the detection device 32 in the alarm device 18 and the power cut-off device 41 in the blower 40. . Then, the detection device 32 of the alarm device 18 detects the operation of the power interruption device 41 (the amount of current flowing through the blower 40 is zero or close to zero), and the alarm lamp 8 is lit (or flashes) as described above. Then, the sound generator 21 is activated.

FIG. 5 is a front view of the main power source when viewed from below, and FIG. 6 is a plan view of the main power source when the alarm is connected. Here, the main power supply 10 of the present embodiment has a pair of main power outlets 15 and 15 (respective inner blade receiving holes 15a and 15a) at a distance L1 from a reference line B (shown as a virtual line) that passes between them. Thus, they are separated from each other (equal distance), and are arranged symmetrically on the second connection surface 13. In addition, the above-described separation distance L1 is set to be longer (larger) than the insulation covering dimension L2 (3 mm or more) of the insulating plug 5 so that the two insulating plugs 5 can be connected in parallel to the pair of main power outlets 15 and 15. is there.
The alarm device 18 has a width L3 on one side (a width on the side facing the insulating plug 5 connected to the original power outlet 15) that is the same as or shorter (smaller) than the separation distance L1. For this reason, the alarm device 18 can always be connected to the other source power outlet 15 different from the one, without the insulating plug 5 connected to the one source power outlet 15 being in the way.

FIG. 7 is a schematic side view of the main power source and the alarm device. (I) is a diagram of the state where the back surface of the alarm device faces the installation surface, and (II) is a diagram where the alarm device surface faces the installation surface. It is a figure of a state. Here, the main power supply 10 of the present embodiment is configured to be inclined downward so that the second connection surface 13 of the pair of the main power supply outlets 15 faces the outside in order to easily connect the alarm device 18.
In the alarm device 18, in the connected state, the vertical dimension (the thickness from the main body plug 12 to the back surface 18b) is formed so as to form a gap (maximum clearance L4 in the present embodiment) between the back surface 18b and the installation surface 16a. Direction dimension). On the other hand, the front surface 18a of the alarm device 18 protrudes in the thickness direction from the back surface 18b (configured as a protruding portion), and the protruding height dimension L5 is set to be larger (higher) than the maximum clearance L4. is there. And as above-mentioned, the warning light 8 and the optical sensor 6 are arrange | positioned at this alarm surface 18a.
When the alarm device 18 tries to connect to the original power outlet 15 from the lower side with the back surface 18b facing the installation surface 16a, the alarm device surface 18a (protruding portion) does not face the installation surface 16a. It can be connected to the outlet 15. On the other hand, when the alarm device 18 tries to connect to the original power outlet 15 with the surface 18a (protruding portion) facing the installation surface 16a from an obliquely downward direction, the alarm device having a protrusion height L5 larger than the maximum clearance L4. The surface 18a (protrusion) is in the way and cannot be connected. For this reason, the alarm device 18 must be connected to the main power outlet 15 with its back surface 18b facing the installation surface 16a, so that the alarm light 8 arranged on the alarm device surface 18a becomes visible and light. The sensor 6 is in a state where sunlight can be stably detected.

According to the alarm device 18 having the above configuration, it can be attached to the blower 40 having the attached plug 2 without modification, and can be installed simply by connecting the main body plug 12 to the main power outlet 15, so that the installation work is extremely simple. It is.
Moreover, even if the alarm device 18 is arranged outdoors, the barrier unit 3 covers the blower plug 2 so that the blower plug 2 is prevented from being damaged or detached. In the outdoor power source 10 (multiple port type), the alarm 18 must be connected to the other main power outlet 15 different from the other one even if the insulating plug 5 is connected to the one main power outlet 15. Connectable. Further, the alarm device 18 has a warning light 8 that can be operated day and night and a sound generation device 21. The sound generation device 21 is in an operable state during the day, but is inconvenient noise at night. In order to prevent the occurrence of this, it is possible to make it inoperable. For this reason, the alarm device 18 is an alarm device particularly suitable for outdoor installation by having the above-described configurations.

The alarm device of the present invention is not limited to the appearance, configuration, processing, display example, and the like described in the present embodiment, and various modifications, additions, and deletions can be made without changing the gist of the present invention.
