Description

Automatic opening and closing electric louver made integrally with fire extinguisher}

The present invention is manufactured as an integrated piece by embedding a fire extinguisher in a louver frame for expelling hot air from the outdoor unit to the inside. The louver is configured to open when the outdoor unit is operating and automatically close when the outdoor unit is not operating, and the smoke is on one side of the frame of the louver. When the sensor and temperature sensor are installed, and the smoke concentration and/or temperature measured by the sensor exceeds the set value, the louver automatically closes and the fire extinguisher operates, spraying the fire extinguishing agent into the interior of the outdoor unit to facilitate fire extinguishing. This relates to an electric louver that is manufactured in one piece and can be opened and closed automatically.

In the case of houses in the past, the outdoor air conditioner unit was installed outside the apartment or in exposed spaces, not in the indoor space. This may accelerate the contamination of the outdoor unit and deterioration of the wiring, which may cause a fire.

The actual number of air conditioner fires was 262 in 2018, 223 in 2019, and 221 in 2020, with property damage totaling tens to tens of billions of won. In many of these cases, the cause of the fire was overheating due to aging of the product or damaged wires.

However, in order to change the residential environment and ensure consumer convenience and safety from fire, in the case of newly built apartments, the outdoor air conditioner unit and evacuation area (outdoor air room) are installed in separate spaces with fire walls.

In a separate space, a louver is installed in front of the outdoor unit for the purpose of introducing/ventilating outdoor air so that it can be opened and closed for seasonal use (open for natural ventilation in spring/fall, always closed in winter) or depending on whether the air conditioner is running or not.

The opening and closing method of the louver can be both a manual type, which the user opens and closes directly, and an automatic type, which opens and closes automatically using a drive motor.

However, in the case of a manual louver, the air conditioner may be operated with the louver closed due to the user's unconscious actions or mistakes. In such cases, the performance of the air conditioner may deteriorate or the outdoor unit may overheat, which may cause a fire.

Accordingly, there is a demand for the installation of automatic opening and closing louvers in conjunction with the operation of the outdoor unit to prevent user errors or provide user convenience.

The use/construction of automatic opening/closing electric louvers is possible for both new and existing buildings depending on the automatic opening/closing control method, but there is a problem in that it is only possible for new buildings when the operation is controlled by a central control panel (wallpad).

On the other hand, if a fire occurs due to overheating of the outdoor unit in the event of a malfunction due to a failure of the automatic louver (i.e., the louver does not open when the air conditioner is running), or if a fire occurs due to overheating of the outdoor unit of the air conditioner while the louver is closed or for other reasons, immediate fire suppression is necessary.

Accordingly, in the case of general new buildings, sprinklers or splash-type automatic fire extinguishers are installed on the ceiling of the outdoor unit, but there may be limitations in directly detecting and suppressing the fire area of the outdoor unit.

In addition, if fire suppression is performed with the louver open, the ease of fire suppression may be reduced due to the inflow of external air/oxygen, and in severe cases, it may cause the spread of secondary fire.

Therefore, in the event of a fire, it is necessary to block air inflow through the louvers.
