Description

FIELD OF THE INVENTION [0001] The present invention relates to a fire fighting apparatus,

More particularly, the present invention relates to a fire-extinguishing system for an electric home appliance of a residential home, and more particularly, To rapidly evolve the internal fire of electrical appliances. In addition, when the fire spreads to the outside of electric appliances, tap water is injected as fire extinguishing water to evolve to prevent further spread of fire, thereby minimizing property damage and personal injury caused by fire To a fire extinguishing system for an electric home appliance of a residential home.

The conventional fire-fighting system of a apartment house is composed of a sprinkler device including a fire detector installed in each household and a sprinkler head. When a fire detector detects a fire when a fire occurs, the fire water supplied from the fire- And to suppress the fire.

However, even if the fire detector detects fire and the fire water is supplied to the fire extinguishing device of the conventional apartment house, the sprinkler head is opened only when the fuse provided in the sprinkler head receives heat of a certain temperature (68 ° C or more) The number of living spaces in the whole house space of the apartment house evolves the fire.

However, such a conventional fire-fighting system of a multi-family house has a problem that it is practically impossible to evolve the ignition point at the initial stage of ignition because the fire water is sprayed only after a certain period of time has elapsed after the fire has occurred and the fire has spread to some extent.

In addition, various household electrical appliances are provided in each household. As is frequently reported recently, the dust accumulated in the case of the Kimchi refrigerator is ignited by the arc to generate a fire. In the case of such a fire It is impossible to evolve the ignition point at the initial stage of ignition, so that a small fire spreads, resulting in property damage and personal injury.

A typical Kimchi refrigerator is composed of a food room with a machine room at the bottom of the backside and food containing kimchi at the front. The machine room has a refrigerator with a compressor, a condenser and an evaporator, In order to ventilate the machine room, a plurality of ventilation holes are formed on the back side of the machine room, dust accumulates in the compressor, the condenser, the evaporator, and the power cord constituting the refrigeration device built in the machine room. Which is easily ignited by the heat generated by the arc or the compressor.

In the event of a fire, early evolution is crucial to minimizing property damage and casualties caused by the spread of fire.

(Hereinafter referred to as "prior art 1") and Korean Patent No. 10-0434984 (registered on May 28, 2004) as a prior art relating to a fire-fighting apparatus of a conventional apartment house, 0500362 (registered by Jun. 30, 2005) "Generation piping installation structure of apartment house sprinkler fire extinguishing facility" (hereinafter referred to as "prior art 2") is disclosed.

However, the prior art fails to solve the above-described conventional problems because the water is not concentratedly injected into the electric equipment.

Therefore, it is required to develop a technology that can minimize the property damage and casualties caused by the spread of fire by allowing the rapid evolution of the ignition point at the early stage of the fire in case of a fire in the electrical appliance of the apartment house.

Hereinafter, the operation of the fire fighting apparatus of the apartment house electrical appliance according to the present embodiment will be described.

Since the temperature sensed by the temperature sensor 400 is maintained at the set temperature or lower, the control unit 510 outputs a control command for closing the solenoid valve 210 and the solenoid valve 320 The electromagnetic valve driving unit 520 sends a closing drive signal to the fire extinguishing gas using solenoid valve 210 and the fire extinguishing gas distributing solenoid valve 320 according to the closing control command of the control unit 510, And the extinguishing gas distributing solenoid valve 320 is kept closed and the extinguished water injection by the extinguishing water injection means 200 and the extinguishing gas injection by the extinguishing gas injection means 300 are not performed do.

When a fire occurs in the machine room 41 of the kimchi refrigerator 40 as an electric appliance due to dust and an arc and the temperature sensed by the temperature sensor 400 installed on the inner surface of the machine room rear cover 44 becomes equal to or higher than the set temperature The controller 510 outputs an opening control command to the fire extinguishing gas distributing solenoid valve 320 and the solenoid valve driving unit 520 outputs the fire extinguishing gas distributing solenoid valve 320 according to the opening control command of the control unit 510 The open valve driving signal for the valve 320 is transmitted and the extinguishing gas distributing solenoid valve 320 is opened to supply the extinguishing gas charged in the extinguishing gas tank 310 through the extinguishing gas injection pipe 330 A mechanical chamber 41 is connected to the front end of the extinguishing gas injection pipe 330 through a ventilation hole 45 formed in the machine room rear cover 44 and through a extinguishing gas injection nozzle 340 protruding into the interior of the mechanical chamber 41, .

As a result, the fire generated in the machine room 41 can be evolved at an early stage.

On the other hand, when the detected temperature by the temperature sensor 400 does not drop below the set temperature until the predetermined time elapses even though the extinguishing gas is injected into the machine room 41 by the extinguishing gas injection means 300,

The control unit 510 determines that the fire in the machine room 41 has spread to the outside of the kimchi refrigerator 40 and outputs an opening control command to the fire extinguishing water using solenoid valve 210. When the solenoid valve driving unit 5200 The electromagnetic valve for use for water 210 is opened so that the tap water supplied from the cold water supply pipe 31 is supplied to the fire extinguishing water supply valve 210 and the water supply pipe 220 The horizontal part 222 and the vertical part 223 constituting the vertical part 223 and the digestion water is accelerated by the reducer 230 at the lower end of the vertical part 223, The digestive water spray holes 241a of the upper horizontal pipe 241 and the digestive water holes 242a of the upper and lower straight pipes 242 and 243 constituting the extinguishing water jetting port 240 and the extinguished water The fire extinguishing water holes 244a of the suspended horizontal pipe 244 and the fire extinguishing water holes 245a of the intermediate water pipe 245 Is sprayed is a secondary fire extinguishment.

At this time, the extinguished water sprayed from the water-spraying nozzle 240 is sprayed on the rear surface of the machine room rear cover 44 and is sprayed into the machine room 44 through the ventilation hole 45 formed in the machine room rear cover 44 It is possible to evolve the fire outside and inside the machine room 44.

Therefore, according to the fire fighting apparatus of the electrical appliance of the apartment house according to the present embodiment, when fire due to dust and arc occurs in the inside of the machine room of the Kimchi refrigerator, the fire extinguishing gas injected from the fire- Since the fire evolves and the fire inside and outside the machine room evolves by the digested water injected from the digester water injection means, it is possible to evolve the fire in the machine room of the Kimchi refrigerator early, And damage to people.

Although the Kimchi refrigerator has been described as an example of the electric device in the above-described embodiments, the refrigerator may be applied to a general refrigerator or other electric device having a separate functional unit.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or essential characteristics thereof.
