The air inlet channel 107 communicates with the space below the partition plate 141 .

The burner 20 is disposed at the bottom of the furnace body 10 and below the partition plate 141 and corresponds to the opening 143 for burning gas. The burner 20 is elongated and extends from the left side 103 of the furnace body 10 to the right side 104 of the furnace body 10 . The flame generated by the burner 20 burning gas extends from between the two vertical plates 142 to above the partition plate 141 .

The air guide device 30 is combined with the inner wall of the furnace body 10 and located between the exhaust port 105 and the burner 20 , and the air guide device 30 divides the interior of the furnace body 10 into a first space S1 and a second space S1 The space S2, the first space S1 communicates with the exhaust port 105, the partition 14 and the burner 20 are located in the second space S2. The air guide device 30 includes a first guide plate 32 , a second guide plate 34 , a plurality of partition plates 36 and a baffle plate 38 . The first guide plate 32 and the second guide plate 34 are inclined from top to bottom in the direction of the front side 101 and the rear side 102 from the center of the furnace body 10 , respectively.

The first guide plate 32 has a first top edge 321 and a first guide surface 322 , and the second guide plate 34 has a second top edge 3411 and a second guide surface 322 , 342 . The first and second top edges 321 and 341 are spaced apart and parallel to each other, and extend along a direction parallel to the burner 20 . The first top edge 321 is located higher than the second top edge 341 . The two guiding surfaces 322 and 342 face the second space S2 , and a channel 40 is formed between the two guiding surfaces 322 and 342 , connecting the first and second spaces S1 and S2 . The width of the channel 40 from the front side 101 to the rear side 102 gradually decreases from bottom to top, and an outlet 42 is formed between the first and second top edges 321 and 341 to communicate the channel 40 and the first A space S1. The outlet 42 is located directly above the burner 20 and has a long axis parallel to the extending direction of the burner 20 , wherein the width of the outlet 42 on the long axis is larger than that of the burner 20 The length in the direction of its extension.

The partitions 36 are arranged at intervals at the outlet 42 , and each partition 36 is respectively connected to the first guide plate 32 and the second guide plate 34 and is perpendicular to the two guide surfaces 322 and 342 .

Please refer to FIG. 5 and FIG. 6 , when the burner 20 burns the gas, the flow of the generated hot gas flows upward from the second space S2 and passes through the outlet 42 along with the two guide surfaces 322 and 342 upward. It flows into the first space S1 and is then discharged to the outside through the exhaust port 105 . Since the widths of the two guide surfaces 322 and 342 gradually decrease from bottom to top, the flow velocity of the airflow can be slowed down, so that the hot air can enter the first space S1 more smoothly and reduce the formation of turbulent flow in the second space S2 and avoid the hot air remaining in the second space S2 and the temperature of the second space S2 being too high. When the hot air rises to the first space S1, the flow velocity of the hot air is relatively slow, so it can be discharged from the exhaust port 105 more easily.

Combustion-supporting air entering through the air inlet 106 of the furnace body 10 is supplied by the combustion-supporting air below the partition plate 141 , so it will not affect the flow of the airflow above the partition plate 141 . In addition, the baffle 38 of the air guide device 30 is located at the corresponding exhaust port 105, which can prevent the upward hot air from concentrating in the channel 40 to the exhaust port 105, so that the hot air can pass through the exhaust port 105 in a dispersed manner. Between the partitions 36, the chance of generating turbulent flow is reduced. The two baffles 36 are symmetrically arranged on the left and right with the baffle 38 as the center, so that the passing airflow can enter the first space S1 from the left and right sides of the baffle 38 evenly.

The gas fireplace 200 of the present invention uses the air guiding device 30 with the air guiding effect, so that the hot gas inside the furnace body 10 is smoothly discharged to the outside, thereby reducing the heat accumulated in the second space S2, compared with the existing heat. The gas fireplace can lower the temperature of the tempered glass 12 .
