In general, the gas stove is equipped with a gas stove main body connected to the gas supply pipe and a hood is mounted on the upper side of the gas stove to discharge the smoke or odor generated during cooking of the gas stove to the outside. Fire extinguisher and temperature sensor is provided on the bottom surface to detect the fire, and to extinguish the fire by spraying the extinguishing liquid from the upper side of the stove. Such a conventional fire extinguishing device of the stove as shown in Figure 1 and 2a and 2b. Installation and dismantling was inconvenient because each device was installed separately.

That is, the fire extinguisher 2 is installed in the range hood 1 and the gas sensor 3 and the gas circuit breaker 4 are separately installed.

Hereinafter, the operation of the fire extinguishing device of the gas stove using the home network apparatus according to the present invention including the above configuration will be described in detail using the flowcharts of FIGS. 4 to 7.

Figure 5 is a flow chart showing the action of the gas stove fire extinguishing apparatus using a home network device according to the present invention.

4 to 5, the operation of the fire extinguishing device of the gas stove using the home network device according to the present invention is largely remote control step (S100), reservation setting and driving step (S200), abnormal situation detection and driving step ( S300).

In the dual remote control step (S100), a user connects to the remote signal transmission / reception unit 110 through a telephone from the outside, and the remote signal transmission / reception unit 110 outputs a corresponding signal to the control unit 150. Therefore, the controller 150 grants the user access through a password verification process, and calls the current status such as the current temperature of the gas stove, the gas leak and the open / closed state of the gas valve, whether smoke or odor is generated as a voice message, etc. Send to 102 via the user. Then, the controller 150 drives the gas shutoff, the blower fan 173, or the fire extinguisher 175 according to the user's operation signal transmitted through the telephone line 102.

In the reservation setting and driving step (S200), when the user sets a predetermined time through the input unit 140, the controller 150 counts the time through the timer 130 to cut off the gas at the set time, and The driving state is checked and the driving state and the completion message are transmitted through the remote signal transmission / reception unit 110.

In addition, in the abnormal situation detection and driving step (S300), the controller 150 detects gas leakage and opening of the gas pipe, fire, smoke or odor through the sensing unit 160 to detect the fire extinguishing driver 170. ) To control the gas, and to extinguish and discharge the smoke. At this time, the alarm message to the user through the buzzer 176 and the remote signal transmission and reception unit 110 in case of an abnormal situation such as the above. Will be sent.

Figure 6 is a flow chart showing a remote control step of the operation of the gas stove fire extinguishing apparatus using a home network device according to the present invention.

4 and 6, first, when the user is connected to the home network system through a telephone, a ring signal for outputting a telephone ring is applied to the telephone connection means 111 (S101). Therefore, the telephone connection means 111 detects the ring signal and applies it to the counter 114 through the noise filter 112. Therefore, the noise filter 112 filters the noise from the applied signal and applies it to the counter 114, and the counter 114 counts that the ring signal rings for a predetermined number of times (S102).

If there is a person in the room, it is preferable to set the number of rings in consideration of the time when the person can answer the call. Therefore, if the telephone set in the room is not received during a predetermined number of times, it is determined that there is no person in the room. Therefore, the counter 114 opens the line between the telephone connection means 111 and the controller 150. .

Therefore, the controller 150 outputs a connection signal to the caller through the telephone connection means 111, reads out the password request message stored in the memory 120 and applies it to the voice output means 113 (S103). ).

Therefore, the voice output means 113 converts the applied electrical signal into a voice signal and applies it to the telephone connection means 111 through the noise filter 112. Therefore, the user hears a voice message prompting for a password through the handset, and inputs the password by operating the keypad of the telephone.

Therefore, the user's input signal is applied to the controller 150, and the controller 150 compares the input password with the stored setting password to determine whether the input signal is matched (S104).

As a result of the determination, when both signals match, the controller 150 reads a voice message asking whether to listen to the report message of the current situation stored in the memory 120 and transmits it to the user. Thus, the user will hear, for example, the message "Do you want to hear the status of the current gas stove?" The controller determines whether a signal for determining whether to listen to a current status report is applied from the user (S105).

At this time, if the user wants to hear a report message about the state of the current stove, pressing the keypad set to "Yes", the corresponding signal is applied to the controller 150. Therefore, the controller 150 reads the voice message for the temperature of the current gas stove stored in the memory 120, whether the gas is leaked, the open / closed state of the gas valve, the smoke or the odor, and through the remote signal transmission / reception unit 110. It transmits (S106).

Herein, the data on the state of the current stove is determined by the control unit 150 according to a sensing signal applied from the sensing unit 160 according to a time zone set by the user and determines the state of the stove 120. The controller 150 outputs a corresponding signal by combining the voice message with the voice message set using the state data of the gas stove stored in the latest time zone.

In addition, the controller 150 guides a keypad number set for controlling the operation of each component stored in the memory 120. That is, the controller 150 transmits a message to the controller 150, for example, the gas valve blocking is 1, the blowing fan 173 is driven 2, and the like (S107).

Therefore, the user listens to the report on the state of the gas stove and, if gas is supplied, presses the keypad set for gas shutoff and outputs a gas shutoff control signal through the telephone line 102. Accordingly, the controller 150 controls the switching means 171 so that driving power output from the power supply unit 190 is applied to the valve blocking means 174. Therefore, the valve blocking means 174 is driven to block the gas valve (S108).

At this time, the state detecting means 177 detects the driving of the valve blocking means 174 and when the gas valve is normally shut off, applies a completion signal to the controller 150. Therefore, the control unit 150 reads out the complete voice message stored in the memory 120 and transmits it to the user through the remote signal transmission / reception unit 110 (S109).

Therefore, the user puts out a fire for cooking or other work on the stove before going out, and after a predetermined time has elapsed, the convenience of use is increased because the gas is blocked by controlling the stove over the telephone.

7 is a flowchart illustrating a reservation setting and driving step during the operation of the fire extinguishing device of the gas stove using the home network apparatus according to the present invention.

4 and 7, when the user operates the input unit 140 and selects a function such as “reservation” or “blowing”, the corresponding signal is applied to the controller 150 (S201). ). In this case, when the user selects various functions by operating the input unit 140, the controller 150 determines whether a timer setting signal is applied thereafter (S202).

As a result, when the timer 130 setting signal is applied from the input unit 140 and a driving signal is applied, the controller 150 drives the timer 130 to count the set time. Alternatively, the controller 150 controls the switching means 171 to drive each component when the timer input signal is not applied by the user selecting other items without selecting the “reservation” item, and when the driving signal is applied. Let's do it.

Thereafter, the controller 150 checks the count signal of the timer 130 to determine whether the count of the timer 130 is completed (S203 and S204).

Therefore, when the count completion signal is applied from the timer 130, the controller 150 controls the switching means 171, for example, a line connected to the power supply unit 190 and the valve blocking means 174. Is switched on so that driving power is applied to the valve blocking means (174). Therefore, when the driving power is applied through the switching means 171, the valve blocking means 174 closes the gas valve, thereby blocking the inflow of gas (S205).

Thereafter, the controller 150 drives the valve blocking means 174 as described above and determines whether or not it is normally driven (S206).

Therefore, the state detecting means 177 detects the open / closed state of the gas valve (not shown) and applies the corresponding signal to the controller 150. Here, the state detecting means 177 is described as an example, when a light emitting device (not shown) is installed on one side of the gas valve, a light receiving element (not shown) on the other side, and the blocking means closes the flow path. The light emitted from the light emitting device (not shown) is blocked to prevent light from being received by the light receiving device (not shown), thereby detecting the opening and closing of the gas valve (not shown).

Therefore, the controller 150 determines the normal driving according to the driving state detection signal applied from the state sensing means 177. When the abnormal driving signal is applied from the state sensing means 177, the controller 150 controls the switching means 171 to drive the buzzer 176 to generate a warning sound, and to display the corresponding contents on the display 180. Control to display (S207).

In addition, the controller 150 controls the dialing means 115 and transmits a message corresponding to the abnormal driving to the stored telephone number (S208, S209).

Therefore, the user can recognize that an error has occurred in the function reserved by the user outside or in other places, and can quickly follow up the action.

8 is a flowchart illustrating an abnormal situation detection and extinguishing step during the operation of the fire extinguishing device of the gas stove using the home network apparatus according to the present invention.

4 and 8, the controller 150 receives a detection signal from the sensing unit 160 (S301), and determines whether an abnormal situation is generated according to the received detection signal. That is, whether the gas leaked by the detection signal of the gas sensor 161 (S302), the detection signal of the temperature sensor 162 whether the fire occurs (S303), the detection signal of the ring sensor 163 whether smoke or odor It is determined (S304).

In detail, the gas sensor 161 detects whether the gas leaks from the gas valve or the gas stove, the temperature sensor 162 detects the temperature of the gas stove, and the ring sensor 163 detects the gas stove. Detects whether smoke is generated and outputs the corresponding detection signal. Accordingly, the detection signals output from the gas sensor 161, the temperature sensor 162, and the ring sensor 163 are amplified by the amplifying means 164 and applied to the comparing means 165. Therefore, the comparison means 165 compares the level of the sensing signal applied to the setting level and outputs an abnormal detection signal as a high or low signal when an error occurs with the setting level.

Therefore, when the controller 150 determines that the gas leaks according to the gas detection signal applied through the comparing means 165, the controller 150 controls the switching means 171 to drive the valve blocking means 174 (S305). .

Alternatively, the controller 150 recognizes that a fire has occurred when the current temperature is higher than the set temperature through the temperature sensor 162 and controls the switching means 171 to drive the fire extinguisher 175 (S306).

Alternatively, when it is detected that smoke is generated through the ring sensor 163, the controller 150 controls the switching means 171 to apply power to the motor driving means 172 to operate the blower fan 173. Drive (S307).

In this case, the controller 150 controls the motor driving means 172 to set the rotation speed of the blower fan 173 motor. That is, if the detection signal applied from the ring sensor 163 is greater than the driving level, the error is higher than a predetermined range, the rotational speed per minute of the blower fan 173 is increased, and if it is less than the lower limit, Lowering the revolutions per minute prevents unnecessary power consumption.

In addition, the state detecting means 177 detects a driving state of the blowing fan motor (not shown), the valve blocking means 174, and the fire extinguisher 175 and outputs a corresponding signal to the controller 150. Therefore, the controller 150 checks the driving state of each component, connects to the user's telephone through the dialing means 115, and transmits a message such as gas leakage or fire, smoke or odor. (S308, S309, S310).
