The gas range is a cooking device that heats food using propane gas or the like. The electric range is a device that cooks food by heating with a high-light or induction method.

Recently, researches that harmful gases such as unburned gas and carbon dioxide generated from a gas range are harmful to the health of a family member, and the use of an electric oven for cooking food using electricity is increasing. Especially, the electric range is used as a built-in product for a new residential apartment, a condominium, etc., which is a large-scale residential facility, because it has a merit that the risk of explosion or fire due to use of gas is small.

However, the electric range has a disadvantage of not only a high manufacturing cost but also a large electric cost as a common problem of the electric heating apparatus. On the other hand, propane gas used as a raw material by the gas range is relatively inexpensive. In addition, in the case of an electric range having a low power consumption, since a calorific value is relatively low, a gas range with a good firepower may be more suitable when cooking is required to be learned quickly in a short time.

As described above, since the gas range and the electric range each have distinct advantages and disadvantages, a combined cooking apparatus in which a gas burner and an electric burner (High-Light) are simultaneously installed in one range is manufactured and sold. The use of this gas and electricity range has the advantage that it can be selectively used in consideration of the type of food, the relative price of gas and electricity, and the like.

However, researches have been conducted on how to effectively change the safety device, which has been applied independently of each other, by using the gas and electricity ranges, and to ensure the safety in use of the gas and electric ranges.

As a result of this research, the present invention has a main purpose of providing a gas and electric combined-use range equipped with a safety device developed so as to simultaneously block the use of electric burners in accordance with safety standards of gas burners having a higher risk of fire .

FIG. 1 is a perspective view of a gas and electric combined-use range according to the present invention, FIG. 2 is an exploded perspective view thereof, FIG. 3 is a view showing a state in which components of FIG. to be.

The gas and electric combined-use range equipped with the safety device according to the present invention includes a housing 10, a gas burner component 20 installed in the housing 10, an electric burner component 40, (50). The gas burner component 20 includes a safety unit that cuts off operation of both the gas burner and the electric burner when the cooking utensil placed on the gas burner is overheated.

The housing 10 includes a base body 11 having a frame of a predetermined height so as to mount the respective components above the frame body 10, a frame holder 13 coupled to the base body 11 and receiving a range top plate 14, And a range top plate 14 on which the gas burner mounting hole 15 and the at least one electric burner indicating portion 16, 17 are formed, on which the gas burner is mounted. A plurality of heat dissipation slots (12) are formed on the rim of the base body (11) so that heat generated during the operation of the range can be discharged.

The gas burner component 20 mainly includes gas supply pipes 21 and 23 for transferring gas supplied from the outside to the gas burner, gas burners 26 and 26 connected to one end of the gas supply pipes 21 and 23, ). The gas burner 26 is mounted on a fixing bracket 22 provided on the base body 11 and the gas burner 26 is mounted on the gas burner mounting hole 15 of the range top plate 14 The packing 24 and the tripod support 25 are fixedly installed. A burner lid 31 having a mounting hole at its center is placed on the gas burner 26 and a temperature sensor 29 is mounted on the sensor bracket 28 in the mounting hole of the burner lid 31, Respectively.

The temperature sensor 29 is installed to contact the bottom surface of the cooking utensil placed on the gas burner 26 to measure its temperature. More specifically, the temperature sensor is inserted into the center of the gas burner 26 so as to be resiliently supported. When the cooking device is placed on the gas burner 26, the temperature sensor is elastically biased downward, To the bottom surface of the cooking utensil.

The gas burner component 20 includes a safety unit as a main component according to the present invention. The safety unit receives the detection signal from the temperature sensor 29. 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. Although not shown, the control controller 33 is also connected to the gas valve unit for controlling the gas supply amount by a relay line.

Reference numeral 27 denotes a spark plug for generating a spark in the gas burner 26. Reference numeral 30 denotes a thermocouple for monitoring flame for controlling the flame to be continuously emitted when a flame is detected and reference numeral 32 denotes a burner cup for mounting a gas burner .

The electric burner component 40 is mainly composed of electric burners 41 and 43 provided with a heat generating means for generating heat by using electricity and an electric burner installed on an electric supply line electrically connected to the electric burners 41 and 43 And electrical control units (42, 44). The electric control units 42 and 44 control the amount of electric power supplied to the electric burners 41 and 43 in conjunction with the electric control knobs 54 and 55 to control the amount of heat generated by the electric burners 41 and 43.

As shown in FIG. 2, the electric burners 41 and 43 may be installed more than two as necessary. 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-

Further, the electric burners 41 and 43 may be operated in an induction manner in which the container is heated using a high-frequency magnetic field. The induction method has the advantage that there is no risk of burning because it is energy efficient and does not directly heat the top plate, though there is a limitation that a dedicated container is used.

Finally, the fuel conditioning component 50 is divided into a gas burner part and an electric burner part. The gas burner part includes a gas valve unit 56 for controlling the amount of gas supplied to the gas burner 26 and a gas control knob 53 rotatably attached on the gas valve unit 56. The range user can adjust the fire power of the gas burner by operating the gas control knob 53.

The electric burner part includes regulators 54 and 55 for controlling the amount of electric power supplied to the electric burners 41 and 43 and electric control knobs 51 and 52 rotatably attached on the regulators 54 and 55 do. The range user can adjust the thermal power of the electric burner by operating the electric control knobs 51 and 52. [ The regulators 54 and 55 turn on / off the electric power or control the electric power supply if necessary.

In FIG. 3, the relay lines 34 and 35 for interrupting the safety unit are connected to the electric control units 42 and 44 coupled to the electric burner component 40. However, the present invention is not limited thereto, and in another embodiment, the electric isolation relay lines 34 and 35 may be connected to the regulators 54 and 55 of the fuel regulating unit 50. At this time, the regulators 54 and 55 serve as the electric control units 42 and 44.

In either case, the control unit 33 of the safety unit receives the detection signal from the temperature sensor 29 to judge whether the gas burner 26 is overheated. Thus, the electric power supplied to the electric burners 41, So that the construction and operation are the same.

Hereinafter, two operation methods of the gas and electric combined-use range equipped with the safety device according to the present invention will be briefly described.

In the first operation method, the temperature sensor 29 outputs a detection signal when the bottom surface temperature of the cooker raised to the gas burner 26 reaches a predetermined reference temperature of 250 to 300 DEG C, When the detection signal is inputted, simultaneously outputs a signal for shutting off the gas and electricity to the gas valve unit 56 and the electric control units 42 and 44.

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 26 reaches the reference temperature between 250 and 300 캜, the control unit 33 of the safety unit is connected to the gas valve unit 56 And outputs an electric shutoff signal to the electric control units 42 and 44 connected through the relay lines 34 and 35 for interrupting the electric power.

As a result, when the cooking apparatus placed on the gas burner 26 is overheated and a danger such as a fire is detected, the operation is cut off not only to the gas burner 26 but also to the electric burners 41 and 43, This makes it possible to prevent the danger from spreading from a gas burner to an electric burner.

In the second operating method, the temperature sensor 29 outputs a detection signal when the bottom surface temperature of the cooker placed on the gas burner 26 reaches the reference temperature of 250 to 300 ° C, and the safety unit And when it is recognized that the temperature has reached the first reference temperature through the sensing signal, it firstly outputs an electric cut-off signal to the electric control unit (42, 44) And outputs a gas shutoff signal to the gas valve unit 56 when it is recognized that the gas temperature has reached the second reference temperature.

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 burners 41 and 43 before reaching the maximum temperature. For example, as shown in FIG. 4, when the food contained in the cooking pot 60 put on the gas burner boils before reaching the cut-off maximum temperature of the gas burner, and the boiling food reaches the adjacent electric burner It may enter the cooking pan 70 in which it is placed and enlarge 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.

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