BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric oven range, and more particularly, to a top burner control method of an electric oven range that protects a product from a temperature rise inside a system due to radiant heat of a top burner.

Recently, a gas range, a gas / electric oven, a microwave oven and the like have been used as a device for cooking at home.

 Here, since the gas oven range is provided with an oven part, a grill part, and a top burner part, a variety of dishes can be used using a single device, and thus the use of the gas oven range is greatly increased in homes and businesses.

In a typical gas oven range, as illustrated in FIG. 1, an oven unit 1 is installed at a lower side of the apparatus to perform barbecue cooking by using vertical thermal power and tropical flow. The grill unit 2 is installed to perform grilling, such as fish, using various kinds of foods, and a plurality of burners 3 for heating a container containing food are exposed on the upper portion of the grill unit 2. The top burner part 4 is provided.

The top burner unit 4 of the gas oven range shown in FIG. 1 is ignited by the ignition spark generated by the ignition means while the gas is supplied from the gas supply pipe. In this case, the burner 3 is exposed upward. Since the flame generated from the burner 3 was exposed to the outside, there was always a risk of fire.

In addition, when the food is heated, the broth contained in the container overflows, the burner 3 is easily extinguished, and salt holes are easily blocked by the broth or foreign substances, causing problems such as poor combustion.

The electric burner type of a hidden burner type using electricity was developed to solve various problems in the open burner type gas oven range.

Here, the hidden burner type electric oven range is composed of a top burner with an electric burner.

As shown in FIG. 2, the electric oven range having a radiant burner includes an oven unit 10 for cooking using a vertical thermal power and a tropical stream, and an oven unit 10 installed above the oven unit 10. It is composed of a grill unit 20 for cooking by using, and a top burner unit 30 installed on the grill unit 20 to heat a container containing food.

At this time, the top burner part 30 is covered with an outer case 31 having a predetermined inner space so that the upper side is opened, and the cooking container is placed on the upper opening of the outer case 31. The glass 32 to be installed, the burner housing 34 which is disposed in the lower portion of the glass 32 and coupled to form an exhaust passage 33 between the glass 32, and generates radiant heat using electricity Consists of a heating coil 36 is composed of a radiant burner 35 installed in the burner housing 34.

Referring to the cooking operation using the top burner unit 30 configured as described above, when the user places a cooking container containing food on the glass 32 and operates the operation button, electricity is supplied to the heating coil 36. The heating coil 36 is heated to high temperature.

At this time, the radiant heat generated while the heating coil 36 is heated to heat the cooking vessel while passing through the glass 32 to cook the food contained in the cooking vessel.

That is, the electric oven range having a radiant burner constitutes a radiant burner composed of a heating coil instead of a gas burner, and cooks food using radiant heat generated from the heating coil.

Electric oven range of the above configuration, the user input means consisting of a plurality of buttons for instructing the operation of the oven portion, the grill portion, the top burner portion, the circuit board of the control module for controlling the operation of the system as a whole It is provided in the upper front side of this top burner part 30. As shown in FIG.

On the other hand, various kinds of electrical elements are installed on the circuit board of the control module by soldering, etc. In the case of such a control module, the control module operates with an electrical signal such as a central processing unit (CPU) or an integrated circuit (IC) to achieve high performance. An integrated circuit package is included.
Since heat generated in the integrated circuit package is a direct cause of deteriorating the performance of an electric circuit, a heat sink is generally used as a means for dissipating heat generated from an entire circuit board.
The heat sink is made of a material having excellent thermal conductivity and is installed on the upper surface of the control module as a heat dissipation element that receives heat from the circuit board of the control module and releases it into the atmosphere.

However, since the control module is located at a position adjacent to the top burner unit 30, the heat generated from the circuit board as well as the heating coil power level increases as the temperature of the radiant heat generated from the burner increases, thereby increasing the internal temperature of the control module. Will rise.

As a result, the internal temperature of the control module is abnormally increased, so that cooling through the heat sink is not performed properly, and various electric parts may be damaged, and further, the reliability of the product may be deteriorated.

The present invention is to solve the above problems, the object of the present invention is to prevent the abnormal rise in the temperature of the internal circuit that controls the overall system and to minimize the damage of the product due to the internal temperature rise of the electric oven range It is to provide a top burner control method.

Therefore, according to the present invention, it is possible to prevent product damage due to overheating by automatically adjusting the power level of the burner according to the ambient temperature of the heat sink for dissipating heat generated from the circuit board.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention that can specifically realize the above object will be described.

3 to 5, the top burner control apparatus and the control method of the electric oven range according to the present invention will be described.

First, as shown in FIG. 3, the apparatus for controlling the top burner of the electric oven range according to the present invention is generated in the burner driver 200 for controlling the power level of the heating coil 100 and in the circuit board of the top burner. A temperature sensor 300 for detecting an ambient temperature of a heat sink (not shown) for dissipating heat, and a power according to the ambient temperature of the heat sink detected by the temperature detector 300. The microcomputer 400 controls the burner driver 200 to set a downward setting level of the level and to downwardly adjust the power level of the heating coil to the set downward setting level.

The present invention relates to a radiant type electric oven range using the heating coil 100 as a heating source of the top burner like the model shown in FIG. 2.

In addition, the temperature sensing unit 300 includes a thermistor whose internal resistance is variable according to the ambient temperature as shown in FIG. 4.

In this case, the temperature sensing unit 300 is installed at a position adjacent to the heat sink (not shown) as a means for sensing the ambient temperature of the heat sink (not shown) installed on the circuit board, the temperature sensing unit 300 of the The output terminal is connected to the input port P1 of the microcomputer 400.

That is, the internal resistance of the thermistor is varied according to the temperature sensed by the temperature sensing unit 300 to output the corresponding voltage level to the microcomputer 400. In this case, the voltage level input from the microcomputer 400 is read. The ambient temperature level of the heat sink is determined.

In addition, the microcomputer 400 detects an ambient temperature of the heat sink through the temperature sensing unit 300 while cooking using the top burner unit, and protects various electronic components of the circuit board from a high ambient temperature. The power level of the heating coil 100 is adjusted according to the sensed ambient temperature of the heat sink.

Referring to the top burner control method of the electric oven range according to the present invention configured as described above in detail.

First, when a user wants to cook using the top burner unit, a cooking container containing food is placed on the burner upper surface and selects the power level (P / L) of the top burner unit.

For example, when the power level of the burner selectable by the user is composed of ten levels, the user selects and uses an appropriate power level among 0 to 9 levels in consideration of the type of cooking and the type of the cooking object.

At this time, the heating coil 100 is heated according to the power level selected by the user, the food contained in the cooking container is heated and cooked due to the radiant heat generated while the heating coil 100 is heated (S10).

As described above, while cooking using the top burner unit is performed, the ambient temperature T of the heat sink detected by the temperature sensing unit 300 is periodically read (S12).

It is determined whether the ambient temperature T of the read heat sink is 70 ° C. or less (S20). When the heat sink temperature T is 70 ° C. or less, the power level of the current heating coil 100 is determined (S10). The power level selected by the user is maintained in the process (S22).

Meanwhile, when the heat sink temperature T is 70 ° C. or higher and 80 ° C. or lower, the power level of the current heating coil 100 is adjusted downward to 4 levels which are intermediate levels among the user selectable power levels 0 to 9. Hold (S30, S32).

On the other hand, after adjusting the power level of the heating coil 100 to 4 levels, if the heat sink temperature (T) is sensed below 70 ℃, the power level of the current heating coil 100 is adjusted upward by one step, In the step S10, the controller adjusts the power up by one step every predetermined time up to the power level selected by the user (S34 and S36).

While the power level of the heating coil 100 is adjusted upward, the heat sink temperature T is read from the temperature sensing unit 300, and the power of the heating coil 100 is changed according to the heat sink temperature T in the same manner as the above process. Adjust the level.

On the other hand, if the heat sink temperature (T) sensed by the temperature sensor 300 is 80 ℃ or more and at the same time less than 90 ℃ after the predetermined time after adjusting the power level of the current heating coil 100 to 4 levels Down step by step (S40, S42).

At this time, if the heat sink temperature (T) is within the range of 80 ° C ~ 90 ° C, first downgrade to an intermediate level (4 levels), and then downwardly adjust by one step every predetermined time up to a minimum power level (0 level) selectable by the user. It is preferable.

In addition, when the heat sink temperature T is lowered to 70 ° C. or less by periodically detecting the heat sink temperature T while down-adjusting the power level of the heating coil 100 step by step, the power level selected by the user is selected. Step up to the level again (S44, S46).

On the other hand, if the heat sink temperature (T) detected through the temperature sensing unit 300 is more than 90 ℃ and at the same time less than 95 ℃ to adjust the power level of the current heating coil 100 to the lowest power level 0 level (S50) , S52).

At this time, if the heat sink temperature (T) is within the range of 90 ° C ~ 95 ° C it is preferable to immediately downgrade to zero level.

While maintaining the power level of the heating coil 100 at 0 level, the heat sink temperature T is periodically detected and when the heat sink temperature T falls to 70 ° C. or lower, the power level is reset to the power level selected by the user. Up step by step (S54, S56).

On the other hand, if the heat sink temperature (T) sensed through the temperature sensor 300 exceeds 95 ℃ to force off the burner (Sut) (S60).

Therefore, the present invention automatically adjusts the power level of the heating coil 100 in accordance with the heat sink temperature (T) to prevent product damage due to overheating. That is, the power level selected by the user is maintained in the range of 70 ° C. or lower, and adjusted to the power level corresponding to four levels, which are intermediate levels, in the range of 70 ° C. to 80 ° C. Moreover, after adjusting to 4 levels in 80 degreeC-90 degreeC, it adjusts downward to the lowest power level by one step, and adjusts to the lowest level in 90 degreeC-95 degreeC range.

The present invention is not limited to the above-described embodiments, and can be modified by those skilled in the art as can be seen from the appended claims, and such modifications are within the scope of the present invention.
