Then, the driving source for forcibly injecting outside air into the gas oven range is exhaust gas (H) passing through the upper exhaust guide 40 and the forced cold air (C) of the forced outside suction gas oven range ( 20) A cooling fan 70 forcibly evacuating to the front side is installed inside the fan duct 78.

Then, a rear suction port 74, which is another inlet for forced suction of external cold air, is installed at the rear of the gas oven range 20. In addition, an exhaust door 76 serving as an outlet for exhausting the high temperature exhaust heat H of the oven cavity 28 and the external cold air C forced into the gas oven range to the outside of the gas oven range is provided in the oven door ( Installed at the top).

Next, the operation by the gas oven range front exhaust structure of the present invention having the configuration as described above will be described.

The high temperature exhaust heat H of the gas oven range oven cavity 28 collects primarily in the collecting part 34 through the plurality of inlets 32 of the lower exhaust guide 30. The exhaust heat H primarily collected in the collecting part 34 moves along the bottom surface 36 of the lower exhaust guide 30. The bottom surface 36 of the lower exhaust guide is configured to be inclined upward toward the rear of the inlet 32 so that the exhaust heat H of the oven cavity 28 is smoothly discharged.

The high temperature exhaust heat H moved along the bottom surface 36 of the lower exhaust guide 30 passes through the central cutout 43 and the side cutout 45, as shown in FIG. 2. The high temperature exhaust heat H of the oven cavity 28 passing through the central cutout 43 and the side cutout 45 is guided by the central slitting 42 and the side slitting 44, respectively. Then it flows to the exhaust port 76.

As described above, the hot exhaust heat H of the oven cavity 28 is formed in the upper exhaust guide 40 along the bottom surface 36 of the lower exhaust guide 30 inclined by passing through the plurality of inlets 32. By taking a path discharged by the cutout 42 and the side cutout 44, the exhaust heat H may flow back into the oven cavity 28 to prevent the phenomenon of being sucked.

That is, if the exhaust heat (H) is immediately discharged to the front exhaust flow path without forming the collecting portion 34 as described above, the oven cavity (driven) driven by a convection motor (not shown) installed on one side inside the oven cavity 28 ( 28) A backflow phenomenon may occur in which exhaust heat H discharged from the oven cavity 28 is returned to the oven cavity 28 again due to tropical flow therein. The formation of the collecting part 34 can prevent such a reverse flow phenomenon.

On the other hand, when the cooling fan 70 is rotated by the driving of the fan drive source (not shown), the external cold air (C) is forced into the gas oven range through the front suction port 71 installed in the lower front of the gas oven range. Is inhaled. The outside cold air (C) forcedly sucked through the front suction port 71 provides oxygen to the oven burner 26, and then rises along the suction duct 72, and then the gas oven range by the fan duct 78. Heads to the front. When the cooling fan 70 rotates, external cold air C is also forced into the gas oven range through the rear suction port 74.

Cold air (C) forced to be sucked from the outside as described above is sucked into the front exhaust passage and the cold air supply passage formed by the upper exhaust guide 40, the lower flow guide 50 and the upper flow guide 60.

When the cold air C forced out from the outside forms a front exhaust flow path and is forced to the exhaust port 76, the central slitting 42 and the lower flow guide 50 of the upper exhaust guide 40 are formed. The flow rate of air flow through the orifice is very fast. Therefore, the exhaust heat H passing through the central cutout 43 passes through the central cutout 43 at a high speed by the Bernoulli's flow rate clearance and is exhausted to the front of the gas oven range.

The phenomenon Bernoulli flow rate cleanup as described above is of course also applied to the case of the exhaust heat (H) passing through the side cutout (45). However, there is only a difference that an orifice formed by the central slitting 42 and the lower flow guide 50 is smaller than an orifice formed by the side slitting 44 and the lower flow guide 50.

Therefore, since the exhaust heat H is quickly discharged through the central cutout 43 and the side cutout 45, the exhaust heat H that is collected in the collecting part 34 and the inside of the oven cavity 28 are increased. The high temperature exhaust heat H is also exhausted quickly and smoothly in series.

As described above, the cold air C sucked from the outside and the high temperature exhaust heat H of the oven cavity 28 are mixed in the front exhaust passage. The reason for mixing the exhaust heat (H) exhausted to the front of the gas oven range with the cold air (C) as described above is that, when the high temperature exhaust heat (H) is exhausted through the exhaust port 76 as it is, injuries to the user This is to prevent the inconvenience of following.

The external cold air C passing through the fan duct 78 is forcedly blown by the cooling fan 70 into the front exhaust flow path, while also forcedly blown by the cold air supply flow path. In addition, only cold air C of low temperature flows in the cold air supply flow path.

Cold air C flowing under the guidance of the upper flow guide 60 and the lower flow guide 50 flows into the opening 52 by the flow of the shielding film 62 of the upper flow guide 60. The shielding film 62 is formed in a diagonal shape so that the flow of cold air C in the cold air supply passage is easily changed toward the opening 52.

As described above, the cold air of the cold air supply passage passing through the opening 52 is mixed with the downstream of the front exhaust flow passage and exhausted through the exhaust port 76 to the front of the gas oven range. At this time, the temperature of the exhaust air finally exhausted through the exhaust port 76 is further lowered by mixing the cold air C into the low temperature cold air supply flow path.

The upper exhaust guide 40, the lower flow guide 50, and the upper flow guide 60 each have a narrow structure at the rear and a wide width at the front, so that the front exhaust flow path and the cold air supply flow path flow. This will be smooth.

The technical gist of the present invention described above is as follows.

The high temperature exhaust heat H of the oven cavity 28 is collected in the collecting portion 34 formed by the lower exhaust guide 30 and the upper exhaust guide 40. The exhaust heat H collected in the collecting part 34 is mixed with external cold air C forcibly sucked by the rotation of the cooling fan 70 to reduce the temperature, and the upper exhaust guide 40 and the lower flow path. Guide to the front exhaust passage consisting of a guide (50).

And, the external cold air (C) is also guided by the cold air supply passage consisting of the upper flow guide 60 and the lower flow guide 50, the flow of the cold air supply flow path of the low temperature is the opening 52 It is mixed with the flow through the front exhaust passage.

The flow of the front exhaust flow path including the exhaust heat H is mixed with the flow of the low temperature cold air supply flow path and exhausted to the front of the gas oven range at a lower temperature.

The gas oven range front exhaust structure according to the present invention has been described with reference to the case of the built-in type, but is not limited to this, of course, it is also applicable to the case of freestanding type.

The above embodiments of the present invention are merely one embodiment of the technical idea of the present invention, and of course, other modifications are possible within the technical idea of the present invention.

According to the configuration and operation of the present invention as described above is expected the following effects.

Forced suction of external cold air forms the flow of air flow path, and by exhausting the exhaust heat generated in the oven of the gas oven range to the flow of the fast air flow path formed by the external cold air flow gas oven range smoothly By exhausting to the outside, the effect of improving combustion performance and cooking performance is expected.

The exhaust heat discharged from the oven is mixed with cold air forcedly sucked from the outside, and the exhaust heat whose temperature is lowered is exhausted to the front of the gas oven range, thus providing a safe environment for users of the gas oven range by preventing from burns and the like. have.
