Description

Fire Extinguisher System For a Residential Kitchen}

The present invention belongs to the technology of extinguishing the fire by accurately detecting the fire in the kitchen.

In general, a gas stove for cooking food and a connection hose for supplying gas to the gas stove are installed in the kitchen. The gas stove has the risk of gas leakage and fire, and when the user goes out or falls asleep with the light on and off, it causes a fire accident.

Currently, fire alarms and fire extinguishers are installed in kitchens to prevent this. However, fire alarm devices and automatic injection devices installed in the kitchen operate only when a fire occurs in the kitchen. Accordingly, it is difficult to grasp whether the fire alarm device and the automatic injection device can be operated in normal times.

In particular, those who have moved to a place where a fire alarm device and an automatic spray device are installed consider the existing kitchen fire extinguishing device as an accessory, and are not paying much attention to whether it actually works.

Accordingly, fire alarm devices and automatic fire extinguishing liquid injection devices are often left unattended and not properly operated. As such, the automatic injection device, which is left unmanaged and neglected by people's indifference, is not able to extinguish a fire initially.

Accordingly, there is a problem in that it is not possible to prevent a situation in which a large fire is caused by not being able to extinguish an easily extinguished flame.

However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. However, this embodiment is only provided to complete the disclosure of the present invention and to completely inform the scope of the invention to those of ordinary skill in the art to which the present invention pertains.

In the present specification, a residential kitchen fire extinguishing system is generally described with reference to FIG. 1 so that the description may be concise and clear. Hereinafter, components included in the residential kitchen fire extinguishing system will be described in detail with reference to the description and FIGS. 2 to 8.

1 is a view showing a state of use of a residential kitchen fire extinguishing system according to an embodiment of the present invention.

The residential kitchen fire extinguishing system 1 makes it possible to self-diagnose even if the fire extinguisher unit 60 is not used for a long time and check whether the fire extinguisher unit 60 is activated. More specifically, the residential kitchen fire extinguishing system 1 can self-diagnose whether the fire extinguisher unit 60, which is not used for a long time, operates normally and whether the reception control unit 40 normally outputs a signal. Through this, the residential kitchen fire extinguishing system 1 can be installed in a residential kitchen to prevent an explosion and fire accident due to gas leakage in the kitchen.

The residential kitchen fire extinguishing system 1 comprises a gas range unit 10, a range hood unit 20, a detection sensor unit 30, a reception control unit 40, a blocking unit 50, and a fire extinguisher unit 60. Include as.

And Figure 5 is a view showing a state of monitoring the pressure gauge module of the fire extinguishing container of Figure 1 with a pressure sensor, Figure 6 is a view showing a connection state between the fire extinguisher unit including the disconnection check module and the reception control unit. 7 is a view showing a connection state between a fire extinguisher unit including an automatic three-way valve and a receiving unit, and Fig. 8 is a view showing time-temperature data used for the reception control unit to control the operation state of the shutoff unit.

The gas range unit 10 includes at least one crater and becomes a gas range in which various cooking utensils and containers are placed on the crater. The gas range unit 10 is connected to the gas pipe 110 to receive gas supplied from the outside and use the supplied gas as fuel. The gas lane part 10 emits a flame through the crater to heat the container. A range hood part 20 is installed on the upper end of the gas range part 10.

The range hood 20 discharges dust and odors generated during the cooking process to the outside. For example, the range hood unit 20 may be a ventilator operated by power and signals applied from the outside. In addition, the range hood unit 20 may be provided with a temperature sensor 310 that measures heat generated from the gas range unit 110. In this case, the temperature sensing sensor 310 may be one sensor included in the sensing sensor unit 30 including various sensors. As an example, the temperature sensor 310 may include an infrared sensor or a thermal imaging camera that measures the surface temperature of a container mounted on the gas range unit 10, that is, the first temperature. And it may include a thermistor (Thermistor) that is commonly used.

The temperature sensor 310 can quickly and accurately detect container and ignition point temperature data. As an example of inaccuracy in measuring the temperature of the container and the ignition point, the temperature sensor 310 may be formed in a structure in which 2 to 3 thermistors are connected in parallel, that is, in an OR in case of failure.

The temperature sensing sensor 310 having such a structure may measure the temperature of the gas range even if any one thermistor fails. In addition, the measured temperature data may be transmitted to the reception control unit 40. The temperature sensor 310 may be installed in the range hood part 20 located in line with the crater of the gas range part 10. Through this, the temperature sensor 310, that is, an infrared sensor or a thermal imager, can accurately measure the surface temperature of the container placed on the crater of the gas range 10.

In addition to the temperature detection sensor 310, the detection sensor unit 30 may include a gas detection sensor 320 that detects gas leaked from the gas pipe 110. Here, the temperature sensor 310 measures the temperature of the gas range unit 10 and transmits temperature data to the reception control unit 40. The temperature sensor 310 measures the temperature of the gas range unit 10 and transmits the measured temperature data to the reception control unit 40.

The gas detection sensor 320 is installed spaced apart from the gas pipe 110 and detects gas leaking from the gas pipe 110. For example, the gas detection sensor 320 may be installed on the ceiling of the kitchen to detect gas leaking from the gas pipe 110. Moreover, the gas detection sensor 320 may measure the concentration of gas mixed with air in the atmosphere and accurately measure the leaked gas. Then, the measured data is transmitted to the reception control unit 40 in real time. In addition, the detection sensor unit 30 may further include an earthquake detection sensor 330, a dust detection sensor 340, a person detection sensor 350, and a pressure detection sensor 360.

Here, the earthquake detection sensor 330 is installed spaced apart from the gas range unit 10 to detect movement of the installation surface. For example, the earthquake detection sensor 330 may be installed on the ceiling of the kitchen and the floor of the kitchen to detect the movement of the ceiling or the movement of the floor. When the installation surface of the earthquake detection sensor 330 shakes, an earthquake detection signal is generated and transmitted to the reception control unit 40 so that the blocking unit 50 and the fire extinguisher unit 60 are operated.

When the detection sensor unit 30 further includes such an earthquake detection sensor 330, the present invention cuts off gas supply and injects extinguishing liquid when an earthquake occurs, so that an explosion accident by gas does not occur when an earthquake occurs. do.

The dust detection sensor 340 is installed spaced apart from the gas range unit 10 to detect dust. For example, it is installed on the ceiling of a kitchen to detect dust generated when cooking food. The dust detection sensor 340 generates a dust detection signal when dust is detected above a preset reference dust. Then, the dust detection signal is transmitted to the reception control unit 40 so that the range hood unit 20 is operated. That is, when the dust detection sensor 340 detects dust above the reference dust, it drives the range hood 20 so that the dust is discharged to the outside.

When the detection sensor unit 30 further includes a dust detection sensor 340, the present invention automatically operates the ventilation fan of the hood according to the amount of dust generated during cooking so that the dust can be discharged to the outside.

The person detection sensor 350 is installed spaced apart from the gas range unit 10 to detect infrared radiation emitted by a person. More specifically, infrared rays are detected from the heat emitted by humans. Such a person detecting sensor 350 may be installed on the ceiling of the kitchen to detect a person. The person detection sensor 350 operates the blocking unit 50 by transmitting a blocking signal to the reception control unit 40 when infrared rays are not detected for a preset time. Through this, gas supplied to the gas range unit 10 is blocked. In addition, the person detection sensor 350 transmits a blocking signal to the reception control unit 40 and may turn off the range hood unit 20 that the user forgets and does not turn off the range hood unit 20. That is, power supplied to the range hood 20 is cut off.

When the detection sensor unit 30 further includes a person detection sensor 350, the present invention determines whether a person has been detected for a certain time, and when no person is detected for a certain time, the gas supply is cut off and the gas range part (10) stops the operation. Through this, it is possible to prevent the occurrence of a fire that may occur when food placed on the gas range 10 is burned.

The pressure detection sensor 360 is installed to be spaced apart from the pressure gauge module 640 of the fire extinguisher to detect the pressure of the pressure gauge module. As an example, the pressure sensor 360 may be a sensor installed in the pressure gauge module 640 to detect a change in gauge. Alternatively, as shown in FIG. 5, it is formed as a vision sensor, that is, a camera, measures the gauge of the pressure gauge module 640 and transmits pressure data of the fire extinguisher to the reception control unit 40.

Such a pressure sensor 360 generates an alarm when the pressure drops from 70% of 9Kg/cm ² . This allows the user to recognize that the fire extinguisher unit 60 is in an abnormal state.

When the detection sensor unit 30 further includes the above-described pressure sensor 360, the present invention makes it possible to check whether the fire extinguisher unit 60 is in operation at normal times, and is installed in a place where the user cannot easily see. The base 60, for example, to allow easy management of the fire extinguisher unit 60 installed inside the cupboard.

The reception control unit 40 includes a control module 410 and a reception module 420 and is connected to the detection sensor unit 30 and the voice output module 80. The reception control unit 40 receives data transmitted from the detection sensor unit 30 through the reception module 420. Then, the received data and preset data are calculated to output a preset voice message from the voice output module 80 connected to the reception control unit 40.

For example, the voice output module 80 outputs a message saying, "If edibles remain in the container, do not pour water into the container and cover the fire part with a wet towel." Through this, the user can more effectively extinguish the fire generated during the cooking process. In addition, the reception control unit 40 may output various messages based on signals input through the temperature sensor, the disconnection check module 670, the pressure sensor 360, and the earthquake sensor 330. Through this, the user can more clearly grasp the current situation. The reception control unit 40 as described above enables to guide fire suppression.

In addition, the reception control unit 40 receives the temperature measured from the temperature sensor 310, that is, the first temperature, and calculates it with preset data. And the operation of the blocking unit 50 is controlled using the calculated data.

For example, the reception control unit 40 receives temperature data measured from the temperature sensor 310, that is, first temperature data. The temperature sensor 310 may measure the surface temperature of the container placed on the gas range unit 10 and transmit it to the reception control unit 40. The reception control unit 40 calculates whether the first temperature data has reached a preset ignition point temperature range, and when the first temperature data is included in the preset ignition point temperature range, the first temperature of the first temperature data does not change. Extract. And the extracted first time is compared with a preset reference time. At this time, when the first time is less than a preset reference time, the reception control unit 40 maintains the operating state of the cut-off unit 50 so that gas is supplied to the gas range unit 10.

On the other hand, when the first time is greater than a preset reference time, the reception control unit 40 operates the blocking unit 50 so that gas is no longer supplied to the gas range unit 10.

In this way, the reception control unit 40 may calculate the data to guide the user to extinguish the fire and control the operation of the blocking unit 50. In addition, the reception control unit 40 may be a computer. Here, the control module 410 further includes a display LED 411 corresponding to a sensor included in the detection sensor unit 30, a check switch 412 and a first connector 413 that are manually operated and generate a path signal. Include. Here, the first connector 143 is connected to the second connector 601 formed on the fire extinguisher unit 60 or the third connector 671 formed on the disconnection check module 670.

The user can determine whether the various sensors installed and the blocking unit 50 operate normally using the display LED 411 and the inspection switch 412. In addition, by connecting the first connector 413 connected to the second connector 601 to the third connector 671, it is possible to check whether the reception control unit 40 operates normally according to whether the light bulb 672 is turned on.

A detailed description of the operation of the blocking unit 50 and the fire extinguisher unit 60 will be described later.

The blocking unit 50 is a device that blocks gas and electricity. The blocking unit 50 is installed in the gas pipe 110 and connected to the reception control unit 40 to receive the first control signal and the second control signal, and control the gas moving along the gas pipe. In addition, the blocking unit 50 is installed in the range hood unit 20 and the electric stove installed in the kitchen and controls the operation of the range hood unit and the electric stove according to a control signal transmitted from the reception control unit 40.

As an example, the blocking unit 50 is a direct-connected blocking device as shown in (a) of FIG. 3, an electronic blocking device as shown in (b) of FIG. 3, and as shown in (c) of FIG. Likewise, it can be formed as an electric cut-off device. This cut-off part 50 is formed of a direct-connected cut-off device and an electronic cut-off device, is installed on the gas valve of the gas pipe, and when the first control signal is transmitted from the receiving control part 40, the gas range part ( 10) Let the gas flow. On the other hand, when the second control signal is transmitted from the reception control unit 40, gas does not flow from the gas pipe 110 to the gas range unit 10. That is, the blocking unit 50 may control the gas supplied to the gas range unit 10 according to the control signal transmitted from the reception control unit 40.

At this time, the reception control unit 40 is connected to the third connector 671 formed on the branch line 660 with the first connector 413 and may be connected to the light bulb 672. Here, the branch line 660, the third connector 671, and the light bulb 672 may be the disconnection check module 670. In addition, the disconnection check module 670 may be formed by various modifications from one to a device capable of confirming disconnection of all input and output lines according to the technical standards of the Gas Safety Corporation. And, depending on the situation, the disconnection check module 670 may further include a device that performs an alarm function.

When the first control signal is applied, it is turned on to emit light, and when the second control signal is applied, it is turned off and it may be formed as a traffic light that does not emit light. In addition, the fire extinguisher unit 60 includes an automatic three-way valve 680 for selectively selecting a first route and a second route, and a first connection pipe 681 connecting the fire extinguisher unit 60 and the automatic three-way valve 680.
