When the temperature of the bottom surface of the cooking apparatus becomes equal to or higher than the reference temperature, the safety unit stops operation of the gas burner 26 as well as electric burners 41 and 43 Do it. To this end, the safety unit comprises a control controller 33 and relay lines 34, 35 extending from the control controller 33 to the electric burner component 40.

In this case, the safety unit may be configured to sense an electrical operation signal of two or more electric burners to selectively output an electric cutoff signal only to the electric burners currently operating in order to increase the accuracy of the electric cutoff.

In addition, the electric burners 41 and 43 are operated in a high-light manner, and a range top plate 14 heated by the high-light can be mounted on the upper portion of the housing 10 . Since the high-light is a method of applying heat to the top plate of the direct cooking range, it can be used without distinction of the container, and there is a characteristic that the cooking can be performed using the residual heat even when the high-

As described above, there is a risk that the burner of the high-light type burns when the user touches the top plate without recognizing the remaining heat even after the operation is stopped. In the present invention, the alarm unit 60 is separately configured to protect the user from such a danger. The specific configuration of the alarm unit 60 will be described later.

The alarm unit 63 is installed in the housing 10 and is electrically connected to the control unit 33 of the safety unit. When a signal for detecting that the user is approaching from the behavior detection sensor 61 is input while the residual heat remains after the operation of the electric burners 41 and 43 is stopped, the control unit 33 controls the alarm unit 63) to alert the user.

5 shows a system for implementing a safety control method using the gas and electric combined range according to the present invention.

The safety control system according to the present invention mainly includes a sensor unit, a safety control unit, and a shutdown and alarm unit.

The sensor unit includes a temperature sensing sensor 100 and a behavior sensing sensor 110.

The temperature sensor 100 is installed to contact the bottom surface of the cooking utensil placed on the gas burner and measure its temperature. The temperature sensor 100 performs a function of informing the safety control unit of whether or not the gas burner is overheated. The behavior detection sensor 110 is installed in front of the housing of the range to detect whether the user is approaching. The behavior detection sensor 110 performs a function of notifying whether or not the user approached while the residual heat remains in the electric burner in the safety control unit.

The safety control unit 200 includes a temperature determination unit 210, a behavior sensing unit 220, a burner shutoff unit 230, and an alarm generating unit 240.

The temperature determining unit 210 determines whether the bottom surface temperature of the cooking utensil placed on the gas burner has reached a reference temperature from the temperature sensing signal input from the temperature sensor 100. [ The behavior detection unit 220 receives a signal from the behavior detection sensor 100 to detect whether the user is approaching the robot and transmits the signal to the alarm generation unit 240. The burner shutoff unit 230 outputs a signal for shutting off the gas and electricity when the temperature of the bottom surface of the cooking apparatus reaches the reference temperature as a result of the discrimination in the temperature discrimination unit 210.

The alarm unit 320 generates a warning sound that can be recognized by the user in response to a warning sound generating signal input from the alarm generating unit.

6 to 8, several embodiments of a safety control method for a combined gas and electric burner range according to the present invention will be described in detail.

6 shows a control method when the electric burner is normally stopped by the user. First, when the user uses the electric burner to cook, the electric knob is turned to stop the operation of the electric burner. At this time, the safety control unit recognizes that the electric burner is normally stopped from signals of the electric regulator or the electric control unit (S60).

The safety control unit calculates how long the residual heat remains after the electric burner is stopped (S61). The time for generating the residual heat of the electric burner is calculated in consideration of the time at which the electric burner is operated, the temperature at the time of operation, the electric capacity used, the performance and specifications of the electric burner,

The safety control unit detects whether there is an action that the user accesses through the signal input from the behavior detection sensor (S62). The safety control unit may be configured to check whether the user approaches the range again after the initial waiting time required for the user to finish cooking and move the cooking utensil or the like.

If it is detected that the user is approaching the range, the safety control unit determines whether the user approaches the range within the remaining heat generation time of the calculated electric burner (S63). As a result of the determination, if the user approaches the range within the residual heat generation time, the control unit outputs a control signal to the alarm unit to generate a warning sound to the extent that the user can recognize it (S64).

7 and 8 show two control methods when the electric burner is abnormally stopped.

The first control method shown in Fig. 7 shows a control method of simultaneously shutting off the gas burner and the electric burner when the gas burner is overheated to be above the reference temperature.

The safety control unit analyzes the temperature sensing signal inputted from the temperature sensing sensor and detects that the bottom surface temperature of the cooking appliance placed on the gas burner reaches a predetermined reference temperature of 250 to 300 캜 (S70). If it is detected that the reference temperature has been reached, a signal for shutting off the gas and electricity is simultaneously outputted to the gas valve unit and the electric control unit (S71).

According to the KS standard of the current gas range, it is required to provide a temperature control device capable of shutting off the gas at a bottom surface temperature of the cooking device put on the gas burner at 300 캜 or lower. Since it is difficult to actually measure the temperature of the bottom surface of the cooking apparatus, it is tested by putting the frying oil used for the measurement of thermal efficiency into a test pot of a certain standard, igniting the gas burner, and measuring the maximum temperature of the oil.

In order to comply with the KS standard, it is preferable that the gas burner is configured to output a gas and an electric cutoff signal when the bottom surface temperature of the cooking appliance reaches a predetermined reference temperature of 250 to 300 ° C.

According to the present embodiment, when the bottom surface temperature of the cooking apparatus put on the gas burner reaches a reference temperature of between 250 and 300 캜, the control unit of the safety unit outputs a gas shutoff signal to the gas valve unit, And outputs an electric cut-off signal to the electric control unit connected through the electric interrupting relay line.

As a result, when the cooker placed on the gas burner is overheated and a danger such as a fire is detected, the gas burner is shut down to the electric burner as well as the electric burner is damaged. So that it can be prevented from spreading.

Thereby, since the gas burner and the electric burner are no longer operated, the risk of overheating is primarily blocked. However, in the case of an electric burner, there is still a residual heat, so there is a high possibility that an image burns when a user touches his / her hands unintentionally. Accordingly, even in this case, the safety control unit calculates the residual heat generation time of the electric burner (S72). If it is detected whether there is an action of the user approaching the range within the calculated residual heat generation time, Ventilate to avoid reaching the range (S73 to S75). The process of generating a warning sound according to the remaining heat time has been described in detail with reference to FIG. 6 and will be referred to here.

The second control method shown in Fig. 8 is a control method of sequentially shutting off the gas burner and the electric burner when the gas burner is overheated to a reference temperature or more.

The safety control unit analyzes the temperature sensing signal input from the temperature sensing sensor and detects that the bottom surface temperature of the cooking apparatus placed on the gas burner has reached the first reference temperature of 250 to 300 ° C (S80). When it is recognized that the temperature has reached the first reference temperature, the electric shutdown signal is firstly output to the electric control unit first (S81), and it is judged that the second reference temperature is higher than the first reference temperature And outputs a gas shutoff signal to the gas valve unit 56 at a time when it is recognized (S83, S84)

When the risk of the cooker being overheated by the gas burner 26 is detected, it is necessary to block the operation of the electric burner before reaching the maximum temperature. For example, as shown in FIG. 4, the food contained in the cooking pot 70 put on the gas burner boils before reaching the cut-off maximum temperature of the gas burner, and this boiled food is fed to the adjacent electric burner It may enter the cooking pan 80 and spread the flame.

Therefore, even before reaching the maximum temperature for shutting off the gas burner, the operation of the electric burner is cut off in advance, thereby further enhancing the safety. To this end, two reference temperatures are set. When the bottom surface temperature of the cooking apparatus placed on the gas burner reaches the first reference temperature, the electricity supplied to the electric burner is cut off. When the bottom surface temperature of the cooking apparatus reaches the first reference temperature It is preferable that the gas supplied to the gas burner is cut off when the second reference temperature is reached which is higher than the second reference temperature.

Thereby, the risk of overheating is cut off because the gas burner and the electric burner are no longer operated. However, in the case of an electric burner, there is still a residual heat, so there is a high possibility that an image burns when a user touches his / her hands unintentionally. Therefore, in this case also, the safety control section calculates the time for generating the residual heat of the electric burner (S82). The calculation of the residual heat generation time is executed simultaneously with the operation of the electric burner being stopped and executed independently of whether the gas burner has reached the second reference temperature (S83).

If it is detected that there is an action of the user approaching the range within the calculated residual heat generation time, a warning sound is generated to alert the user to approach the range (S85 to S87). The process of generating a warning sound according to the remaining heat time has been described in detail with reference to FIG. 6 and will be referred to here.

As described above, the present invention has been described with reference to particular embodiments, such as specific elements, and specific embodiments and drawings. However, it should be understood that the present invention is not limited to the above- And various modifications and changes may be made thereto by those skilled in the art to which the present invention pertains.
