Abstract

The present invention relates to a fire alarm with an enhanced structure to facilitate a first action in case of fire by enabling people to care the fire alarm in normal. The fire alarm providing a warning signal to people in case of fire according to the present invention comprises a temperature sensor which measures the ambient temperature to detect whether a fire occurs and a warning light which includes a plurality of light sources to change the color of the light according to the measured temperature in the temperature sensor.

Description

Fire alarm device

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire alarm, and more particularly, to a fire alarm installed in a building to inform the occurrence of a fire.

In a stairway or corridor of a building, a fire alarm indicating the occurrence of a fire is installed. Such a fire alarm is disclosed in, for example, Japanese Patent Application Laid-open No. 10-2001-0094488.

1 is a schematic block diagram of a conventional fire alarm.

Referring to FIG. 1, the smoke alarm 9 is installed on the wall of a staircase or a corridor, together with a fire hydrant. The fire alarm is provided with a button 1 for manually generating an alarm sound when a fire occurs, a speaker 2 for generating a warning sound, and a warning light 3 for indicating that the fire alarm is normally operating .

Conventional warning lamps include a light source of one color (red). Normally, red light is always on so that the smoke alarm is normally operating, and at the same time, the position of the smoke alarm can be checked at night. When a fire occurs, the warning light blinks to visually confirm that a fire has occurred.

However, in the case of conventional fire alarms, since the warning lamps are in a single color, they are not normally attracted to the attention of the people. After the fire has occurred, the temperature sensor detects a high temperature. . Therefore, there is a problem in that it is impossible to cope with a first accident when a fire occurs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a smoke alarm improved in structure so that people can take care of a fire alarm .

A fire alarm according to the present invention is a fire alarm for generating a warning signal to people when a fire occurs. The fire alarm includes a temperature sensor for measuring an ambient temperature to detect whether a fire occurs, A warning light including a plurality of light sources is provided.

According to the present invention, it is preferable that the warning lamp includes a plurality of LED bulbs which output light of different wavelengths.

According to the present invention, because people are interested in a fire alarm even in normal times, the awareness of a fire can be improved, and furthermore, the room temperature can be visually confirmed, so that it is possible to cope with a fire accident.

1 is a schematic block diagram of a conventional fire alarm.
2 is a schematic perspective view of a fire alarm according to an embodiment of the present invention.

Hereinafter, a fire alarm according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

2 is a schematic perspective view of a fire alarm according to an embodiment of the present invention.

2, the smoke alarm 100 according to the present embodiment includes a case 10, a warning sound generating button 20, a temperature sensor (not shown), a control unit (not shown), a warning lamp 30), and a warning sound generating unit (40).

The case 10 is mainly formed in a rectangular parallelepiped shape, and is installed in a form embedded in a wall of a building. The case 10 is provided with a door 11 that can be opened and closed, and a fire hose or the like is disposed inside the door when the door is opened.

The alarm sound generating button 20 is installed at the upper end of the case. When a person manually presses the alarm sound generating button, a beep sound is generated in the alarm sound generating unit to be described later.

The temperature sensor is installed at a position where a fire is to be detected, for example, in a ceiling of a room. The temperature sensor measures the temperature around the temperature sensor and transmits it to the control unit.

The control unit controls the operation of the warning lamp and the warning sound generating unit in accordance with the temperature measured by the temperature sensor.

The warning lamp 30 is for allowing people to visually recognize the current room temperature. For this purpose, the warning lamp includes a plurality of light sources emitting light of different colors (wavelengths), in this embodiment, the warning lamps include a plurality of LED bulbs 31 emitting light of different colors. For example, four LED bulbs 31 for emitting blue, green, white, and red light.

The warning sound generating unit 40 is electrically connected to the control unit and generates a warning sound.

Meanwhile, the smoke alarm may further include a lamp 50 that visually indicates whether the smoke alarm is normally operated. This lamp is composed of a single color bulb, like a conventional warning lamp, and when the lamp is on, it indicates that the smoke alarm is operating normally.

Hereinafter, an operation method of the smoke alarm 100 configured as described above will be described.

First, the temperature measured by the temperature sensor is transmitted to the control unit, and the control unit changes the color of the warning light according to the temperature. For example, when the temperature is below 20 ° C, the blue LED bulb is turned on so that the warning lamp turns blue. And, at 20 ~ 30 ℃, the green LED bulb is turned on so that the warning lamp turns green, and at 30 ~ 40 ℃, the white LED bulb turns on. At a temperature of 40 ° C or higher, the red LED bulb is turned on, and the warning lamp is displayed in red so that people are aware that the temperature of the room has abnormally increased.

At the same time, at a high temperature of 40 ° C or higher, a warning sound is generated in a warning sound generating unit, thereby notifying people of the danger signal audibly.

As described above, according to the present embodiment, since the color of the warning lamp changes according to the room temperature, it is possible to concentrate the attention of people visually. Accordingly, people can be aware of the fire and be more interested in the fire than before, and it is possible to efficiently transmit the occurrence of fire to people.

In addition, since the temperature of the room can be recognized by people at various stages, people can actively take action against the fire (for example, it can evolve in the first place in the event of a fire).

Furthermore, since the LED bulb having excellent power efficiency is used, it has an advantage in terms of energy saving.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation in the embodiment in which said invention is directed. It will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.

For example, the temperature range at which color changes and the number and type of colors may vary.
