Abstract

A heating cooking appliance is provided. The heating cooking appliance includes a case, a plate covering a top of the case, a burner system generating heat by combusting mixture gas in the case, a control unit controlling operation of the burner system, and a temperature increase preventing unit preventing a temperature of the control unit from increasing by the heat generated from the burner system. The temperature increase preventing unit is installed on the case.

Claims

1. A heating cooking appliance comprising:

a case;

a plate covering a top of the case;

a burner system generating heat by combusting mixture gas in the case;

a control unit controlling operation of the burner system; and

a temperature increase preventing unit preventing a temperature of the control unit from increasing by the heat generated from the burner system, the temperature increase preventing unit being installed on the case.

2. The heating cooking appliance according to claim 1, wherein the temperature increase preventing unit includes a barrier preventing the heat from being transferred from the burner system to the control unit.

3. The heating cooking appliance according to claim 2, wherein the barrier includes:

a first barrier rib for preventing the heat from being transferred from the burner system frontward;

a second barrier rib for preventing the heat from being transferred upward; and

a third barrier rib for preventing the heat from being transferred sideward.

4. The heating cooking appliance according to claim 2, wherein the barrier rib is provided with a hole through which a gas supply pipe for supplying the gas to the burner system passes.

5. The heating cooking appliance according to claim 2, wherein a seating portion for allowing the barrier to securely seating on the case is formed on a lower portion of the barrier.

6. The heating cooking appliance according to claim 2, wherein the barrier divides an internal space of the case into a first space in which the burner system is disposed and a second space in which the control unit is disposed;

and a fan for cooling the control unit is disposed in the second space.

7. The heating cooking appliance according to claim 6, wherein the fan is operated in accordance with a detection result of a thermostat detecting a temperature of heat transferred from the burner system.

8. The heating cooking appliance according to claim 1, wherein the temperature increase preventing unit includes a fan for cooling the control unit.

9. The heating cooking appliance according to claim 8, wherein the fan is operated in accordance with a detection result of a thermostat detecting a temperature of heat transferred from the burner system.

10. The heating cooking appliance according to claim 1, wherein the burner system includes a burner pot in which gas and air are mixed with each other;

a glow plate disposed on the burner pot and heated by combustion heat of the mixture gas; and

a sub-heating unit disposed above the glow plate and further combusting the mixture gas that is not combusted.

11. The heating cooking appliance according to claim 10, wherein the burner system includes a supporting member that supports the sub-heating unit such that the sub-heating unit is spaced apart from the glow plate.

12. The heating cooking appliance according to claim 11, wherein the sub-heating unit is provided in the form of wires wound around the supporting member.

13. The heating cooking appliance according to claim 11, wherein the sub-heating unit is formed in a coil shape and coupled to the supporting member with predetermined elastic force.

14. A heating cooking appliance comprising:

a case;

a plate disposed on the case;

at least one burner system provided in the case and generating heat by combusting mixture gas;

a control unit isolated from the burner system and controlling operation of the burner system; and

a fan disposed near the control unit and cooling the control unit.

15. The heating cooking appliance according to claim 14, further comprising a thermostat detecting heat generated from the burner system, wherein the fan operates in accordance with a detecting result of the thermostat.

16. The heating cooking appliance according to claim 15, further comprising a spark plug for igniting the mixture gas of the burner system;

and

a thermal detecting rod protruding into the burner system and extending out of the burner system,

wherein the thermostat detects a temperature transferred to the heat detecting rod.

17. The heating cooking appliance according to claim 16, wherein the spark plug includes a pair of ignition rods and the thermal detecting rod is disposed between the ignition rods.

18. The heating cooking appliance according to claim 16, wherein the spark plug includes a pair of ignition rods and the thermal detecting rod functions as one of the ignition rods.

19. The heating cooking appliance according to claim 16, further comprising a grounding wire connected to the thermal detecting rod and a grounding member coupled to the case, the grounding wire being connected to the grounding member.

20. The heating cooking appliance according to claim 16, wherein the thermal detecting rod is provided to each burner system and the thermal detecting rods are commonly grounded to the grounding member.

21. The heating cooking appliance according to claim 16, wherein the thermostat is supported by a support coupled to an extending portion of the thermal detecting rod.

22. A heating cooking appliance comprising:

a case;

a plate disposed on the case;

at least one burner system provided in the case and generating heat by combusting mixture gas; and

a control unit isolated from the burner system and controlling operation of the burner system,

wherein the burner system comprises;

a burner pot providing a space in which gas and air are uniformly mixed with each other;

a first combustion unit for combusting mixture gas in the burner pot;

a second combustion unit for further combusting the mixture gas passing through the first combustion unit; and

a supporting member for supporting the second combustion unit at a location spaced apart from the first combustion unit by a predetermined distance.

23. The heating cooking appliance according to claim 22, wherein a plurality of catching portions for supporting the second combustion unit are formed on the supporting member.

24. The heating cooking appliance according to claim 22, wherein the second combustion unit is provided in the form of wires having a predetermined diameter.

25. The heating cooking appliance according to claim 22, wherein the second combustion unit is formed in a coil shape.
