The sub fan 62 is provided inside the space partitioned by the barrier 63 and the space in which the regulator 51 and the valve unit 52 are disposed by the barrier 63 is connected to the burner 40 can be partitioned. Therefore, the air outside the case 10 flows into the space partitioned by the barrier 63 by driving the sub-fan 62, and the regulator 51 and the valve unit 52 And can be cooled independently of the space in which the burner 40 is disposed.

The fan mounting portion 11 is formed on the bottom surface of the case 10 on which the main fan 61 and the sub fan 62 are mounted. The fan mounting portion 11 is formed to protrude in a shape corresponding to the main fan 61 and the sub fan 62 so that the main fan 61 and the sub fan 62 can be seated.

Since the remaining portion of the case 10 except for the fan mounting portion 11 is sealed, the air introduced into the case 10 can be supplied only through the fan mounting portion 11.

Therefore, the main fan 61 and the sub fan 62 may have a structure in which the main fan 61 and the sub fan 62 are completely in close contact with the case 10, 62 from being leaked to the gap.

Therefore, the air blown by the main fan 61 can effectively cool the PCB 231 spaced apart in a multi-stage manner.

The main fan 61 may be located behind the operation unit 23 and at a position corresponding to the center of the operation unit 23. Therefore, the cooling air blown by the driving of the main fan 61 can be uniformly supplied to the entire operation unit 23. [

In addition, the cooling air supplied from the main fan 61 may be configured to cool both the upper and lower surfaces of the PCB 231. Further, as the main fan 61 is located at a position adjacent to the operation unit 23, the cooling efficiency of the operation unit 23 can be improved.

The cooling air blocking member 53 is provided on both sides of the main PCB 231. The cooling air blocking member 53 may be provided on the bottom surface of the case 10 corresponding to the position of the nozzle 33 and may cover the space between the nozzle 33 and the mixing tube 34 .

The shielding portion 531 is disposed between the nozzle 33 and the mixing tube 34 The nozzle 33 and one side of the mixing tube 34 are shielded so that the air forcedly blown in the rotation of the main fan 61 flows into the space between the nozzle 33 and the mixing tube 34, Thereby preventing an influence from being exerted.

The width of the cooling air blocking member 53 is at least larger than the distance between the nozzle 33 and the mixing tube 34 and the distance between the nozzle 33 and the mixing tube 34 And at least a part of each of the nozzle 33 and the mixing tube 34 is shielded from the side.

Therefore, the cooling air blown by the driving of the main fan 61 is blocked by the cooling air blocking member 53 and can not flow into the space between the nozzle 33 and the mixing tube 34, And is branched by the cooling air blocking member 53 to flow along the periphery of the first burner 401 and the second burner 402.

An exhaust port for discharging the exhaust gas generated after the combustion and the air inside the case 10 is formed at the rear end of the insulator case 31. 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, .

An open portion 316 may be formed at the center of the front end of the insulator case 31. The opening portion 316 is located vertically above the mounting position of the main fan 61 so that when the main fan 61 is driven, (Not shown). Thus, the cooling air passing through the opening 316 can directly cool the lower surface of the top plate 20.

The opening 316 may be formed so as to have a narrower width from the front side toward the rear side, which is the inlet side. Accordingly, intensive cooling air can be blown toward the inlet side of the opening portion 316, and the operation portion 201 and the front half of the top plate 20, which are operated by the user, can be intensively cooled .

The main fan bracket 64 may be mounted on a lower surface of the insulator case 31 so as to cross the opening 316. The main fan 61 is mounted on the main fan bracket 64 and can be positioned vertically below the opening 316.

The main fan bracket 64 includes a fan fixing portion 641 for pressing and fixing the main fan 61 above the main fan 61 and a fan fixing portion 641 extending upward from the fan fixing portion 641, And a fan coupling portion 642 coupled to a lower surface of the base plate 31.

The fan fixing portion 641 is formed in a plate shape which can be contacted along the rim of the main fan 61 and has an opening 641a at the center thereof for allowing air blown by the main fan 61 to pass therethrough . The main fan 61 and the fan fixing part 641 can be fastened to each other by a coupling member such as a screw or a bolt in the fan fixing part 641.

The fan engaging portion 642 includes a pair of first engaging portions 642a extending to the left and right sides of both ends of both sides of the fan fixing portion 641 and a pair of second engaging portions 642b extending rearward from the rear ends of both sides of the fan fixing portion 641 And a pair of second engaging portions 642b.

The first engaging portion 642a extends upward by a predetermined length and then laterally extends to be mounted across the inlet of the relatively wide opening 316. [ The second engaging portion 642b extends to the same height as the first engaging portion 642a and then extends rearward and is then fixed to the outside of the opening portion 316. [

The height of the fan coupling portion 642 may be set to a height that allows the main fan 61 to press the fan mounting portion 11 while pressing the main fan 61 when the main fan 61 is mounted. When the insulator case 31 is seated in the case 10 in a state where the main fan 61 is mounted on the main fan engaging portion 642, So that the outside air can be prevented from leaking.

The barrier (63) is fixedly mounted on both left and right sides of the insulator case (31). The barrier 63 may be fixed by welding or fixed to the insulator case 31 by a separate engaging member S such as a rivet or a bolt or a screw.

The barrier 63 may include a pan seating part 631 for providing a surface on which the sub fan 62 is mounted and a partition part 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 is inserted through the sub-fan 62 and the engaging hole 631b. Accordingly, the sub-fan 62 can be fixed to the fan seating portion 631 by fastening the coupling member S, and the barrier 63 mounted on the insulator case 31 can be fixed to the insulator case 63 31) to be assembled inside the case (10). At this time, the fan mounting portion 631 on which the sub-fan 62 and the sub-fan 62 are mounted can be mounted on the protruding fan mounting portion 11 in a completely close state.

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 partition 632 may include a first partition 632a extending along an inclined end of the fan seating portion 631 and extending outward to partition the case 10, And a second extending portion 632b that is bent at an end of the side exhaust port 632a to partition the side exhaust port 315. [

The first partition 632a defines a space between the insulator case 31 and the case 10 and is configured to guide the flow of air blown by the sub fan 62. [

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.

13 is a view showing an internal air flow state of the gas cooking appliance. FIG. 14 is a view showing a cold air flow state in FIG. 10. FIG. 15 is a partially cutaway perspective view showing a state in which the cooling air and the combustion gas are exhausted from the exhaust part.

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 sub 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.

Another part of the air blown through the main fan 61 flows upward and can directly contact the lower surface of the top plate 20 through the opening 316. Therefore, centralized cooling of the front portion of the top plate 20, particularly at a position adjacent to the operating portion 201 operated by the user, becomes possible.

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 of the combustion gas is lowered and can be discharged to the outside through the vent hole 211 of the exhaust unit 21.

On the other hand, a protruding portion 12 protruding forward is formed on the rear surface of the case 10, and the rear end of the insulator case 31 and the protruding portion 12 are in contact with each other. Therefore, the rear end of the case (31) and the rear surface of the case (10) are separated from each other to form a separate flow path.

Accordingly, the cooling air blown by the main fan 61 flows rearward along the space between the case 10 and the insulator case. A portion of the cooling air from the rear end of the case 10 passes through the center exhaust port 314 and the side exhaust port 315 and is mixed with the combustion gas in the burner 40 and flows through the exhaust port 21 So that it can be discharged. A part of the cooling air flows to the rear end of the case 10 through the center exhaust port 314 and the side exhaust port 315. The rear end of the insulator case 31 and the rear surface of the case 10 Flows through the flow path and can be discharged through the exhaust part (21).

Therefore, it is possible to cool the outer surface of the case 10 by the cooling air, thereby protecting the sink structure where the gas cooking appliance 1 is mounted, or other structures forming the appearance, .

When the sub fan 62 is driven, air outside the case 10 flows into the interior of the case 10, and the air inside the case 10, which is partitioned by the barrier 63, Can be independently cooled.

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

16 is a partial perspective view showing an air flow on the regulator side. 17 is a cross-sectional view showing air flow by the sub-fan.

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

A part of the air forced by the sub 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 sub 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 operates at a high temperature in the case 10, pure outside air not mixed with air at a position adjacent to the burner 40 is supplied to the regulator 51, Can be cooled more effectively.

Another part of the air forced by the sub fan 62 flows along the partition part 632 of the barrier 63 and the second extension part 632b causes the side air outlets 315 ). &Lt; / RTI >

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, 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 flows 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.

Although the cooling structure of the sub-fan 52 has been described with reference to the regulator 51, the cooling structure of the valve unit 52 located at the opposite position is different from the cooling structure of the valve unit 52 only in the direction 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.

18 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.
