Description

Technical Field

[0001] This invention relates to a distribution box for preventing electrical safety accidents in public residential buildings. When a fire occurs due to leakage or short circuit caused by multiple electronic components located inside the distribution box casing, fire-fighting water is sprayed onto the fire to extinguish it quickly in the early stages. Furthermore, a filter unit removes harmful components contained in the smoke generated by the fire, allowing only air with the harmful components removed to be discharged to the outside of the distribution box casing. Background Technology

[0002] Typically, during the construction of public residential buildings, the electrical distribution box is installed on the wall and contains various electronic components such as power distributors, residual current circuit breakers (RCCBs) or wiring circuit breakers, and power meters. The power distributor supplies power according to various loads. When an abnormal state such as leakage occurs, the RCCB can detect the supply voltage under the load and quickly cut off the power supply to prevent electrical safety accidents in advance. The wiring circuit breaker is used to selectively disconnect the load side with abnormality. The power meter is used to measure the total amount of electricity used within a specified time.

[0003] In the event of a leakage or short circuit, a fire may occur. Therefore, such existing distribution boxes may include fire extinguishers to prevent the fire from starting or, in the event of a fire, to prevent its spread.

[0004] However, while the included fire extinguishers can prevent the spread of fire, the electrical distribution boxes in existing public residential buildings present a problem in that they require someone to identify the fire and manually operate the extinguisher, making it difficult to extinguish a fire quickly in its early stages. Therefore, these existing electrical distribution boxes in public residential buildings have the disadvantage of being unable to extinguish fires in their early stages, allowing them to spread into large-scale fires.

[0005] The prior art related to this invention is Korean Patent Publication No. 10-1786459 (publication date: October 17, 2017), which discloses the technology of "public residential electrical distribution panel with fire prevention structure". Summary of the Invention

[0006] Technical issues

[0007] According to several embodiments of the present invention, the object of the present invention is to provide a distribution box for preventing electrical safety accidents in public residential buildings, including a spraying structure, that is, when a fire occurs due to leakage or short circuit caused by multiple electronic components (e.g., residual current circuit breakers) disposed inside the outer casing of the distribution box, fire-fighting water can be sprayed onto the fire in order to quickly extinguish the fire in the initial stage.

[0008] Furthermore, another object of the present invention is to provide a distribution box for preventing electrical safety accidents in public residential buildings, including an exhaust fan that removes harmful components contained in the smoke generated in a fire through a filter and discharges only air that has had its harmful components removed by the filter to the outside of the distribution box housing.

[0009] Technical solution

[0010] According to several embodiments of the present invention, a distribution box for preventing electrical safety accidents in public residential buildings includes: a distribution box housing with multiple electronic components (e.g., residual current circuit breakers) disposed inside; a spray structure disposed inside the distribution box housing for spraying fire-fighting water when a fire occurs due to leakage or short circuit caused by the multiple electronic components disposed inside the distribution box housing; and an exhaust fan disposed in the distribution box housing for removing harmful components contained in the smoke generated by the fire through a filter and discharging only the air to which the harmful components have been removed to the outside of the distribution box housing. The spray structure may include: multiple spray nozzles disposed in... Around the inner wall of the aforementioned distribution box casing, fire-fighting water supplied by a fire-fighting water supply motor is sprayed towards the fire. The fire-fighting water supply motor is connected to the plurality of spray nozzles and drives the fire-fighting water tank, which is located on the upper part of the aforementioned distribution box casing, to supply fire-fighting water to the plurality of spray nozzles. A fire detection sensor is located inside the aforementioned distribution box casing and is used to detect the fire and transmit a fire detection signal, which is then signaled, to a processor. The processor is electrically connected to the aforementioned fire-fighting water supply motor and the aforementioned fire detection sensor and controls the drive of the aforementioned fire-fighting water supply motor based on the received fire detection signal.

[0011] According to several embodiments of the present invention, the aforementioned filter section may be disposed on the front surface of the aforementioned exhaust fan, so that the smoke generated by the fire passes through, and only air with the aforementioned harmful components removed is discharged to the outside of the aforementioned electrical distribution box housing by removing the harmful components contained in the smoke.

[0012] According to various embodiments of the present invention, the processor can control the drive motor of the exhaust fan based on the fire detection signal received in order to start the exhaust fan.

[0013] According to several embodiments of the present invention, a transfer connection portion may be formed in the outer shell of the power distribution box, such that the interior of the outer shell of the power distribution box is connected to the exhaust fan, so as to transfer the flue gas generated from the interior of the outer shell of the power distribution box through the exhaust fan.

[0014] The effects of the invention

[0015] According to several embodiments of the present invention, the electrical safety accident prevention distribution box of a public residential building is configured with a spray structure including multiple spray nozzles. When a fire occurs on the periphery of the inner wall of the distribution box shell due to leakage or short circuit caused by multiple electronic components disposed inside the distribution box shell, the spray structure can quickly extinguish the fire inside the distribution box shell by spraying fire-fighting water from the multiple spray nozzles. Thus, it can not only prevent the fire from spreading inside the distribution box shell, but also prevent the fire from spreading into a large fire and prevent loss of life.

[0016] Furthermore, the electrical safety accident prevention distribution box for public residential buildings includes an exhaust fan. The exhaust fan can remove harmful components contained in the smoke generated by a fire through a filter and discharge only the air that has been filtered to remove harmful components to the outside of the distribution box casing. Therefore, not only can the exhaust fan prevent people from suffocating due to the smoke generated from the distribution box casing, but it can also prevent fatal accidents.

[0038] The electrical safety accident prevention distribution box 100 of public residential buildings according to various embodiments of the present invention may include one or more of a variety of devices. When a fire occurs due to leakage or short circuit caused by multiple electronic components disposed inside the distribution box housing 110, fire-fighting water W1 can be sprayed onto the fire to quickly extinguish the fire in the initial stage. In addition, harmful components contained in the smoke A1 generated by the fire can be removed and only the air A2 with the harmful components removed can be discharged to the outside of the distribution box housing.

Figure 2 This is a cut-out exploded perspective view showing the structure of the electrical safety accident prevention distribution box 100 in a public residential building, according to several embodiments of the present invention, before the door 140 is attached. Figure 3 This is a perspective view showing the assembled state of the electrical safety accident prevention distribution box 100 for public residential buildings according to several embodiments of the present invention. Figure 4 A cut-out perspective view showing the assembled state of the electrical safety accident prevention distribution box 100 for public residential buildings according to several embodiments of the present invention. Figure 5 This is a side sectional view illustrating the working state of the electrical safety accident prevention distribution box 100 for public residential buildings according to several embodiments of the present invention. Figure 6 This is a front view showing the working state of a distribution box 100 for preventing electrical safety accidents in a public residential building according to several embodiments of the present invention.

[0040] Reference Figures 1 to 6 The electrical safety accident prevention distribution box 100 for public residential buildings may include a distribution box housing 110, a jet structure 120, and an exhaust fan 130. For example, electronic components 10 may be disposed inside the distribution box housing 110. For example, the electronic components 10 may include a residual current circuit breaker 10, and in addition to the residual current circuit breaker, the electronic components 10 may also include other components 10. For example, the electronic components 10 may include a power distributor, a wiring circuit breaker, and an electricity meter, etc.

[0041] An opening 110a may be formed on the front surface of the aforementioned distribution box housing 110, and a door 140 may be provided on the front surface of the aforementioned distribution box housing 110, and the aforementioned opening 110a may be opened and closed by rotating the hinge portion 160.

[0042] The aforementioned spray structure 120 can be disposed inside the aforementioned distribution box housing 110. For example, when a fire occurs due to leakage or short circuit caused by the aforementioned plurality of electronic components 10 (e.g., residual current circuit breakers) disposed inside the aforementioned distribution box housing 110, the aforementioned spray structure 120 can spray fire-fighting water W1 to extinguish the fire.

[0043] The aforementioned spray structure 120 may include a plurality of spray nozzles 121, a fire water supply motor 122, a fire detection sensor 123, and a processor 124. For example, the plurality of spray nozzles 121 may be configured around the inner wall of the aforementioned electrical distribution box housing 110. That is, the plurality of spray nozzles 121 may spray the aforementioned fire water W1 supplied by driving the fire water supply motor 122 toward the fire.

[0044] The fire water supply motor 122 can be connected to the plurality of spray nozzles 121. For example, the fire water supply motor 122 can drive the supply of fire water W1 to the fire water tank 125, which is located on the upper part of the distribution box housing 110.

[0045] The fire detection sensor 123 can be disposed not only inside the outer casing 110 of the electrical distribution box, but also on the rear surface of the door 140. For example, the fire detection sensor 123 can transmit a fire detection signal, which is a signal of the detected fire, to the processor 124. The fire detection sensor 123 may include a temperature sensor and a smoke detection sensor.

[0046] The processor 124 can be electrically connected to the fire water supply motor 122 and the fire detection sensor 123. For example, the processor 124 can control the drive of the fire water supply motor 122 based on the received fire detection signal.

[0047] The exhaust fan 130 can be disposed outside the outer casing 110 of the electrical distribution box. For example, the exhaust fan 130 can remove harmful components contained in the smoke A1 generated by the fire through the filter section 131 and discharge only the air A2, from which the harmful components have been removed, to the outside of the outer casing 110 of the electrical distribution box.

[0048] The processor 124 described above can be electrically connected to the drive motor 132 of the exhaust fan 130. For example, the processor 124 can control the drive motor 132 of the exhaust fan 130 based on the fire detection signal received for rotating the exhaust fan 130. The exhaust fan 130 can rotate as driven by the drive motor 132.

[0049] A transfer connection portion 150 may be formed in the aforementioned distribution box housing 110, such that the interior of the distribution box housing 110 is connected to the aforementioned exhaust fan 130, so that the exhaust fan 130 can transfer the smoke A1 generated from the interior of the distribution box housing 110. For example, when the transfer connection portion 150 drives the drive motor 132 of the exhaust fan 130 through the aforementioned processor 124, as the exhaust fan 130 rotates, the smoke A1 generated from the interior of the distribution box housing 110 can be drawn in by the exhaust fan 130.

[0050] In this case, as the flue gas A1 conveyed by the exhaust fan 130 passes through the filter section 131 disposed in the exhaust fan 130, the harmful components contained in the flue gas A1 can be removed.

[0051] In this state, such as Figure 5 and Figure 6 As shown, when a fire occurs due to leakage or short circuit caused by multiple electronic components 10 (e.g., residual current circuit breakers) disposed inside the aforementioned distribution box housing 110, the fire detection sensor 123 disposed on the rear surface of the aforementioned door 140 prioritizes detecting the fire, and the fire detection sensor 123 can transmit a fire detection signal to the processor 124.

[0052] The processor 124 can drive the fire water supply motor 122 based on the fire detection signal.

[0053] As the fire water supply motor 122 is driven, the fire water tank 125 supplies fire water W1 from the fire water tank 125 to the plurality of spray nozzles 121.

[0054] The aforementioned multiple spray nozzles 121 can spray the supplied fire-fighting water W1 to extinguish the fire.

[0055] Therefore, the aforementioned multiple spray nozzles 121 can quickly extinguish fires occurring inside the aforementioned electrical distribution box casing 110 in the initial stage by spraying fire-fighting water W1. This prevents the spread of fire inside the aforementioned electrical distribution box casing 110.

[0056] Furthermore, when a fire occurs in any of the electronic components 10 (e.g., residual current circuit breakers) located inside the aforementioned distribution box housing 110, the fire may generate smoke A1.

[0057] In this case, the fire detection sensor 123 disposed on the rear surface of the door 140 detects the smoke A1, and the fire detection sensor 123 can transmit the smoke detection signal to the processor 124.

[0058] The processor 124 can drive the drive motor 132 of the exhaust fan 130 based on the flue gas detection signal.

[0059] As the processor drives the drive motor 132 of the exhaust fan 130, the exhaust fan 130 can be rotated.

[0060] As the exhaust fan 130 rotates, the flue gas A1 generated inside the electrical distribution box housing 110 can be transferred to the filter section 131 of the exhaust fan 130 via the transfer connection 150.

[0061] As the transferred flue gas A1 passes through the filter section 131, the harmful components contained in the flue gas A1 can be removed by the filter section 131.

[0062] That is, the air A2, from which harmful components have been removed, can be discharged to the outside of the aforementioned distribution box housing 110.

[0063] As described above, as the harmful components contained in the flue gas A1 are removed by the filter section 131, only the air A2, from which the harmful components have been removed, can be discharged to the outside of the distribution box housing 110. Therefore, the exhaust fan 130 can prevent fatal accidents caused by the flue gas A1.

[0064] The electrical safety accident prevention distribution box for public residential buildings described above is not limited to the above embodiments and drawings. It should be understood that those skilled in the art can make various modifications, variations and alterations within the scope of the present invention.
