Description

  The present invention relates to an alarm device provided with detection means for detecting a change in the external environment and notification means for notifying the change in the external environment.

  Conventionally, as this type of alarm device, a sensor as a detection means for detecting a temperature rise or a gas to be detected, and a notification means for visually informing a change in the external environment detected by the sensor by lighting a single lamp or the like The one with is known. Since a technique for notifying a change in the external environment by lighting a lamp or the like in an alarm device is common, patent literature is not described.

  When the alarm device detects a change in the external environment and the notification means having a single lamp is turned on to notify the detected change, for example, a lamp other than the alarm notification, such as a lamp that notifies the input of the power supply, Sometimes it was difficult to distinguish immediately. In this case, there is a possibility that the countermeasure against the change in the external environment may be delayed, for example, by the user reconfirming the presence or absence of the operation of the notification means by approaching the alarm device.

  Accordingly, an object of the present invention is to provide an alarm device that can visually recognize changes in the external environment more visually.

In order to achieve the above object, the alarm device according to the present invention is an alarm device comprising a plurality of detection means for detecting a change in the external environment and a notification means for notifying the change in the external environment. Corresponds to each of the plurality of detection means, and includes a plurality of alarm units that issue alarms by blinking of the lamps, and the plurality of alarm units differ with respect to each change in the external environment detected by the detection unit An alarm unit is assigned to issue an alarm, and in at least one of the alarm units, a plurality of light emitting units arranged at intervals, and formed on an outer surface of the notification unit, from each light emitting unit A plurality of light emitting surfaces that radiate emitted light to the outside at intervals, and a diffusion in which an optical path from each light emitting unit to a light emitting surface corresponding to the light emitting unit diffuses toward the light emitting surface side Part and said A control unit that controls how light is emitted from a plurality of light-emitting units, and the control unit directs the adjacent light-emitting units in one direction in the corresponding alarm unit when performing notification based on each detection means. The control is to sequentially emit light.

The notification unit in this configuration includes a plurality of alarm units corresponding to each of the plurality of detection units, and at least one of the alarm units includes a plurality of light emitting units. According to this configuration, the light emitted from the plurality of light emitting units is radiated from the light emitting surface to the outside of the notification unit via the diffusion unit corresponding to each light emitting unit. The diffusing portion is formed in a conical shape that diffuses toward the light emitting surface, and when the light emitted from the light emitting portion passes through the diffusing portion, the light is emitted from the light emitting surface so as to spread. Thus, the light emitted from the notification means is easily recognized by the user because the range of radiation is widened.

  In addition, the plurality of light emitting surfaces are arranged at intervals. Therefore, each light emitted from each light emitting part is emitted from the corresponding light emitting surface without overlapping, and the outline of the light of each light emitting part can be clearly recognized. This makes it easier for the user to recognize that light (alarm) is emitted from the notification means each time the individual light emitting units are turned on.

In this configuration, after the first light emitting unit is turned on, the adjacent light emitting unit is turned on, and further, the light emitting unit adjacent to the light emitting unit is turned on. Thus, by controlling to emit light sequentially in one direction, it is possible to make the user recognize that the light runs in one direction. For this reason, since the lamp is not simply turned on, it is easy to catch the eye of the user, and it is difficult to mistake it for lighting of a lamp other than notifying an alarm such as a power lamp notifying the input of power. Therefore, measures against fire can be quickly taken.

The 2nd characteristic structure of the alarm device which concerns on this invention exists in the point which formed the said several light emission surface continuously. In this configuration, since a plurality of light emitting surfaces are continuously formed without partitioning, if the adjacent light emitting units are controlled to emit light sequentially in one direction, the user can run the light in one direction. Makes it easier to recognize.

A fourth characteristic configuration of the alarm device according to the present invention is that a light shielding means for shielding at least a part of the diffusion portion and the side of the light emitting surface is provided.
According to this configuration, since at least a part of the diffusing portion and the side of the light emitting surface are shielded so as to be surrounded by the light shielding means, even if the light emitting means disposed in the vicinity of the notification means is turned on. The light does not reach a part of the diffusing portion and the light emitting surface which are shielded by the light shielding means. Therefore, when there is no alarm notification by the notification means, there is no misperception that light is emitted from the notification means.

A fifth characteristic configuration of the alarm device according to the present invention is that a light blocking means is provided in the upper lamp display portion and the lower lamp display portion so that light does not reach the other when one is turned on.
According to this configuration, even if the lamp is lit in the lower lamp display section, the light does not reach the upper lamp display section. Therefore, when there is no alarm notification in the fire alarm section, the upper lamp display section It is possible to prevent misidentification as light is emitted.

The sixth characteristic configuration of the alarm device according to the present invention is that the molding surface of the light emitting surface is formed in an inclined shape so as to radiate light emitted from the light emitting portion obliquely downward.
In many cases, the alarm device is disposed on the upper part of the indoor wall. According to this configuration, when the alarm device is disposed on the upper portion of the indoor wall, the light emitting surface can be provided with the inclined portion so that the light emitting surface faces obliquely downward, so that the light emitted from the light emitting portion is inclined. Can radiate downward. Therefore, it becomes easy to visually recognize the lighting of the light of the notification means from a height lower than the height level where the alarm is provided.

The cover portion 2 may be formed so as to be raised (FIG. 2).

  If the CO sensor can detect carbon monoxide gas generated by incomplete combustion, and the city gas sensor can detect leakage gas such as hydrocarbon gas, a known semiconductor type sensor element or catalytic combustion type gas sensor element Etc. can be used. These sensors are arranged so that carbon monoxide gas and city gas flowing into the alarm device X can be detected through a plurality of slits 3 formed at the upper right side of the case 1.

(Notification means)
For example, when the calculation means 30 described later determines that each sensor has continuously detected smoke concentration, CO concentration and city gas concentration that are equal to or higher than the alarm level, the notification means 20 receives an alarm signal from the calculation means 30. An alarm is triggered by flashing lamps or sound. In the present embodiment, an upper lamp display unit 4 and a lower lamp display unit 5 for visually informing an alarm are provided in the lower front portion of the case 1.

  On the back side of the upper lamp display unit 4, a fire alarm unit 20A that is turned on when the smoke sensor detects smoke is disposed. On the back side of the lower lamp display section 5, there is a power lamp that lights when energized, an incomplete combustion alarm section 20B that lights when the carbon monoxide gas sensor detects carbon monoxide gas above a certain concentration, and a city gas sensor above a certain concentration A city gas alarm unit 20C that is turned on when the city gas is detected is disposed.

As shown in FIGS. 3 and 4, the fire alarm unit 20 </ b> A (a part of the notification unit 20) includes a plurality of light emitting units 21 (21 a to 21 c) arranged at intervals.
On the outer surface of the notification means 20, a plurality of light emitting surfaces 22 (22a to 22c: a part of the upper lamp display unit 4) that radiate light emitted from the respective light emitting units 21 to the outside at intervals. Is formed.
In the optical path from each light emitting unit 21 to the light emitting surface 22 corresponding to the light emitting unit 21, a diffusion unit 23 (23 a to 23 c) that diffuses toward the light emitting surface 22 side is formed.
Furthermore, the fire alarm unit 20A is provided with a control unit 24 that controls how the plurality of light emitting units 21a to 21c emit light.

The light emitting unit 21 can use a known light emitting means such as a light emitting diode (LED) or an incandescent light bulb. The number of the light-emitting parts 21 should just be plural, and the arrangement | positioning mode (a linear form, curved shape, etc.) of the several light-emitting parts 21 and the color of the light emission means used for the light-emitting part 21 are not specifically limited. This embodiment demonstrates the case where the three light emission parts 21a-21c are arrange | positioned at linear form.
In the alarm device X of the present invention, a plurality of light emitting units 21a to 21c are arranged at intervals, and a plurality of light emitting surfaces 22a to 22c corresponding to the respective light emitting units 21a to 21c are arranged at intervals. It is.

  The light emitted from the light emitting unit 21 is emitted from the light emitting surfaces 22a to 22c to the outside of the notification unit 20 via the diffusion units 23a to 23c corresponding to the respective light emitting units 21a to 21c. The diffusing portion 23 may be formed of a resin containing a known light diffusing agent including polymer fine particles and low refractive index inorganic fine particles. For example, when using LED as a light source as the light emission part 21, the spreading | diffusion part 23 is made to exhibit milky-half color or milky white, for example. The diffusing portion 23 is formed in a conical shape that diffuses toward the light emitting surface 22, and when the light emitted from the light emitting portion 21 passes through the diffusing portion 23, the light emitting surface 22 spreads. Radiated from. Thus, the light emitted from the fire alarm unit 20A is easily recognized by the user because the range of radiation is widened.

  The plurality of light emitting surfaces 22a to 22c are arranged at intervals. Therefore, each light emitted from each light emission part 21a-21c is radiated | emitted from the corresponding light emission surface 22a-22c, without overlapping, and the outline of the light of each light emission part 21 can be recognized clearly. .

  In the present invention, the plurality of light emitting units 21 are not lit simultaneously, but the control unit 24 controls the adjacent light emitting units 21 to emit light sequentially in one direction. That is, first, the light emitting unit 21a is turned on, then the adjacent light emitting unit 21b is turned on, and the light emitting unit 21c adjacent to the light emitting unit 21b is turned on. Thus, by controlling to emit light sequentially in one direction, it is possible to make the user recognize that the light runs in one direction. Therefore, it is not an aspect in which the lamp is simply lit, so that the user's eyes can be easily caught.

Various lighting patterns for sequentially lighting the plurality of light emitting units 21 may be set. For example, a plurality of light emitting units 21a to 21c arranged in a straight line are sequentially turned on from the light emitting unit 21a to the light emitting unit 21c, and once the lighting is completed, all the light emitting units 21a to 21c are temporarily turned off, and then the light emitting units are again turned on. Lights up in a similar pattern from 21a. Alternatively, the light emitting unit 21a to the light emitting unit 21c may be sequentially turned on, and once the lighting is completed, all the light emitting units 21a to 21c may be temporarily turned off, and the light emitting unit 21c to the light emitting unit 21a may be sequentially turned on in the reverse direction. .
The timing for turning off the light-emitting section 21 that has been turned on may be controlled so that the light-emitting section 21 is turned off immediately before the adjacent light-emitting section 21 is turned on.

  The molding surface of the light emitting surface 22 described above may be formed in an inclined shape so as to emit light emitted from the light emitting portion 21 obliquely downward (FIG. 3).

In the present embodiment, a smoke sensor or a city gas sensor is used as the detection means 10. Since these sensors detect city gas that is lighter than smoke or air, the alarm device X is usually disposed at the upper part of the indoor wall.
In this configuration, when the alarm device X is disposed on the upper part of the indoor wall, the light emitting surface 21 can be provided with the inclined portion 25 shaped so that the light emitting surface 22 faces obliquely downward. Can be emitted obliquely downward. Therefore, it becomes easy to visually recognize the lighting of the light of the notification means 20 from a height lower than the height level where the alarm device X is disposed.

(Calculation means)
The calculation means 30 includes a concentration calculation unit that calculates the smoke concentration, the CO concentration, and the city gas concentration based on the outputs detected by the sensors described above, respectively, smoke, carbon monoxide gas, and city gas.
Further, when each sensor continuously detects smoke concentration, CO concentration, and city gas concentration that are higher than or equal to the alarm level, the calculation means 30 controls the alarm means 20 to send an alarm signal to the alarm means 20 to issue an alarm. To do.

(Light-shielding means)
In the present embodiment, a light shielding unit 40 that shields at least a part of the diffusion portion 23 and the side of the light emitting surface 22 is provided. The light shielding unit 40 may be any member as long as it can perform the light shielding. For example, a thin metal plate or a resin plate may be used.

As described above, in this embodiment, the upper lamp display unit 4 and the lower lamp display unit 5 are arranged vertically. The case 1 of the alarm device X is usually made of a highly transparent material such as PMMA resin (polymethyl methacrylate resin). Moreover, the diffusion part 23 is made of a resin exhibiting milky white. At this time, for example, when the incomplete combustion alarm unit 20B is turned on in the lower lamp display unit 5, it is conceivable that the light reaches the upper lamp display unit 4 disposed immediately above the lower lamp display unit 5.
At this time, if the light-shielding means 40 is not provided, there is a risk of misunderstanding that light is emitted from the upper lamp display unit 4 even when the alarm is not notified by the fire alarm unit 20A. is there.
However, in the present embodiment, since at least a part of the diffusing unit 23 and the side of the light emitting surface 22 are shielded so as to be surrounded by the light shielding means 40, even if the lamp is turned on in the lower lamp display unit 5, Light does not reach the lamp display unit 4. Therefore, when there is no alarm notification in the fire alarm unit 20A, there is no misperception that light is emitted from the upper lamp display unit 4.

[Another embodiment]
In the above-described embodiment, only the fire alarm unit 20A is configured so that the adjacent light emitting units 21 emit light sequentially in one direction. However, the incomplete combustion alarm unit 20B and the city gas alarm unit 20C also emit a plurality of lights. It is also possible to provide a light emitting unit adjacent to each other and to sequentially emit light in one direction.

  The present invention can be used in an alarm device provided with detection means for detecting a change in the external environment and a notification means for notifying the change in the external environment.
