The exhaust port may include a center exhaust port 314 at the center and a side exhaust port 315 at both sides of the center exhaust port 314.

The center exhaust port 314 may be formed to be somewhat narrower than the area of the side exhaust port 315. This is because the distance between the center exhaust port 314 and the third burner 403 is relatively shorter than the distance between the first burner 401 and the second burner 402 and the side exhaust port 315, Since the exhaust gas can be concentratedly discharged to the center exhaust port 314, the amount of the high temperature exhaust gas discharged through the center exhaust port 314 is reduced to lower the overall exhaust gas temperature.

That is, the amount of the exhaust gas discharged through the side exhaust port 315, which is relatively low in temperature, is greater than the exhaust gas exhausted through the center exhaust port 314, .

The main fan 61, the fan 62, and the barrier 63 may be provided on the lower surface of the insulator case 31.

The barrier 63 may include a pan seating portion 631 for providing a surface on which the fan 62 is seated as a whole and a partition portion 632 for partitioning the inner space of the case 10.

In detail, the fan seating portion 631 is formed in a substantially triangular plate-like shape and is configured to contact the upper surface of the fan mounting portion 11. The fan seating portion 631 is formed with an opening 631a through which the air flows and a coupling hole 631b through which the coupling member S is coupled. The engaging member S passes through the fan 62 and the engaging hole 631b and is engaged. Accordingly, the fan 62 can be fixed to the fan seat 631 by fastening the coupling member S, and the barrier 63 mounted on the insulator case 31 can be fixed to the insulator case 31 So as to be assembled in the inside of the case 10. At this time, the fan mounting portion 631 on which the fan 62 and the fan 62 are mounted can be mounted in a state of being completely in close contact with the protruding fan mounting portion 11.

The fan seating portion 631 is formed in a right triangle shape and one end of the fan seating portion 631 is connected to the partition portion 632 and the other end of the fan seating portion 631 is in close contact with the side surface of the case 10 . Therefore, the barrier 63 can maintain a stable fixed state without generating vibration due to air flow.

The partition portion 632 is vertically bent upward at an inclined end portion of the fan seating portion 631 and fixed to the lower end of the insulator case 31 to define an inner space of the case 10 do.

The second extension portion 632b is bent at the end of the first partition portion 632a and extends to contact the rear end of the case 10 through the side exhaust port 315. [ Accordingly, the side air outlet 315 can be divided into left and right sides with respect to the second extending portion 632b by the second extending portion 632b, and the cooling air flowing along the first partition 632a Air can be independently exhausted through the side exhaust port 315 partitioned by the second extension portion 632b.

A bent portion 633 is formed at the upper end of the first compartment 632a to bend outwardly. The bent portion 633 is brought into contact with the lower surface of the insulator case 31. A coupling member S such as a screw or a bolt is fastened to the bending portion 633 and the insulator case 31 so that the barrier 63 can be fixedly mounted.

Hereinafter, an operation of the gas cooking apparatus according to an embodiment of the present invention will be described.

10 is a view showing an internal air flow state of the gas cooking appliance.

As shown in the figure, the user operates the operating portion 201 exposed to the top plate 20 for use of the gas cooking appliance 1. [ The opening and closing of the valve unit 52 is determined in accordance with the operation signal so that the gas supply to the desired burner 40 can be performed by operating the operation unit 201. [ Lt; / RTI >

When the gas is mixed with air and supplied in the form of a mixed gas to the desired burner 40, it is ignited by the spark plug 32 so that the ceramic mat 42 can be burned and heated. The heating of the ceramic mat (42) allows the ceramic mat (42) to radiate a radiant wave to the outside to heat the container containing the food or the food placed on the top plate.

The user can control the thermal power of the burner 40 through the operation of the operation unit 201. The burner 40 and the radiation wave generated by the heater include visible light, The ignition and heating state can be visually recognized.

Meanwhile, the main fan (61) and the fan (62) are driven together with the ignition of the burner (40). The air in the case 10 can be sucked into the main fan 61 by driving the main fan 61. The sucked air is radially discharged around the main fan 61. [

A part of the air blown through the main fan 61 is blown toward the PCB 231 of the operation unit 23 so that the PCB 231 can be continuously cooled so as to maintain normal operation.

A part of the air blown through the main fan 61 passes between the first burner 401 and the second burner 402 and flows along the outer surface of the third burner 403 toward the center exhaust port 314, respectively.

The other part of the air blown through the main fan 61 flows along the space between the first burner 401 and the second burner 402 and the side surface of the case 10, It flows along the barrier 63 partitioning the space inside the case 10 and can be exhausted to one side of the side exhaust port 315. [

The air in the case 10 is not stagnated by the rotation of the main fan 61 so as to continuously cool the first half of the top plate 20 in which the operation unit 23 and the cooling unit are located, The air in the vicinity of the first burner 401, the second burner 402 and the third burner 403 is exhausted to prevent the temperature inside the case 10 from rising above the set temperature.

When the first burner 401, the second burner 402 and the third burner 403 are burned by the flow of the cooling air discharged through the center exhaust port 314 and the side exhaust port 315 So that the combustion gas can be mixed with the cooling air by the pressure difference and exhausted together. At this time, the high-temperature combustion gas mixes with the cooling air discharged from the inside of the case 10, so that the temperature is lowered and can be discharged to the outside through the vent hole 211 of the grill vent 21.

When the fan 62 is driven, the air outside the case 10 flows into the interior of the case 10, and the air in the second space 62 on both sides of the case 10, which is partitioned by the barrier 63, (S2) can be independently cooled.

Hereinafter, the air flow inside the case 10 by the fan 62 will be described in more detail with reference to the drawings.

11 is a partial perspective view showing an air flow on the regulator side. 12 is a cross-sectional view showing air flow by the fan.

As shown in the figure, the air outside the case 10 is sucked into the case 10 by the rotation of the fan 62. The sucked air is radially discharged around the fan 62 and forcedly flows in the second space S2 defined by the barrier 63. [

A part of the air forced to flow by the fan 62 passes through the regulator 51 to cool the regulator 51. The regulator 51 can be cooled by the air continuously blown by the fan 62 and can be cooled by the air introduced from the outside in the space defined by the barrier 63.

That is, even when the burner 40 is operated at a high temperature in the case 10, the air is divided into the first space S1 in which the burner 40 is located and is not mixed with air at a position adjacent to the burner 40 Pure outside air flows into the second space S2 and is then supplied to the regulator 51 so that the regulator 51 can be cooled more effectively.

Another part of the air forced by the fan 62 flows along the partition 632 of the barrier 63 and flows into the side exhaust port 315 by the second extending portion 632b, As shown in FIG.

The second extending portion 632b extends to the rear end of the case 10 across the side exhaust port 315 and the rear end of the insulator case 31 is protruded from the rear surface of the case 10 12 so as to be spaced apart from the rear surface of the case 10.

A part of the air flowing along the partitioning part 632 may be discharged through the side exhaust port 315 in a mixed state with the combustion gas of the burner 40. Accordingly, It is possible to lower the temperature of the exhaust gas.

The other part of the air flowing along the partitioning part 632 passes through the side exhaust port 315 and through the flow path P between the insulator case 31 and the rear surface of the case 10, (21). Therefore, it is possible to cool the outer surface of the case 10, so that it is possible to protect the sink structure where the gas cooking appliance 1 is mounted or the other structure for forming the appearance so as to prevent the structure from being damaged by heat.

The cooling structure of the valve unit 52 positioned at the opposite position differs only in the direction of the operation, The detailed description thereof will be omitted.

Meanwhile, the gas cooking apparatus according to the embodiment of the present invention may be installed in a separate case, not mounted on furniture such as a sink in a built-in system.

13 is a perspective view of a gas cooking apparatus according to another embodiment of the present invention.

As shown in the figure, the gas cooking appliance 1 according to another embodiment of the present invention has the same configuration of the top plate 20 and the case 10 as the above-described embodiment, The configuration may also be configured identically.

However, the gas cooking appliance 1 according to another embodiment of the present invention may be configured to be seated in an outer case 10 'forming an outer appearance in a state where the top plate 20 and the case 10 are assembled.

Of course, if necessary, the top plate 20 may be directly mounted on the outer case 10 'instead of the case 10, and the burner unit 30 may be installed inside the outer case 10' And all of the components arranged inside the case 10 may be mounted.
