Description

gas fireplace

technical field

The present invention relates to a gas fireplace, in particular to a gas fireplace with a gas guiding device inside the furnace body.

Background technique

Please refer to FIG. 1 , the existing gas fireplace includes a furnace body 1 and a burner 2 . The furnace body 1 has an exhaust port 1a at the top and an air inlet port 1b, the exhaust port 1a communicates with the top of the furnace body 1, and the gas inlet port 1b passes through an air inlet channel at the rear side of the furnace body 1 1c communicates with the bottom inside the furnace body 1 . The front side of the furnace body 1 is open, and a tempered glass 3 is provided. The burner 2 is arranged at the bottom of the furnace body 1, and the burner burns gas to generate a flame. A user can watch flames through the tempered glass 3 .

When the burner 2 burns gas, the air flow of the generated hot gas gradually rises to the top of the furnace body 1 and is discharged from the exhaust port. However, the exhaust port 1b can only allow part of the air flow to pass through, and most of the air flow of the hot gas will be resisted by the top wall in the furnace body 1 and flow back downwards, forming a turbulent flow, causing the hot air to be unable to be discharged smoothly and stay Inside the body of furnace 1. In this way, the surface temperature of the strengthened glass 3 will rise excessively, which may cause burns to personnel.

In addition, when the combustion-supporting air flows in from the air inlet 1h and enters the bottom of the furnace body 1 through the air inlet channel 1c, it is supplied by the side of the burner 2, and the air flow will cause the air in the furnace body 1 The turbulent flow at the bottom will also affect the discharge of hot air.

detailed description

Referring to FIGS. 1 to 6 , a gas fireplace 200 according to a preferred embodiment of the present invention includes a furnace body 10 , a burner 20 and a gas guiding device 30 .

The furnace body 10 has a front side 101 , a rear side 102 , a left side 103 and a right side 104 . The inner width of the furnace body 10 gradually expands from the rear side 102 to the front side 101 . The front side 101 of the furnace body 10 is open, and the front side 101 is provided with a tempered glass 12 closing the open portion, and the user can watch the flame in the furnace body 10 through the tempered glass 12 .

The top of the furnace body 10 has an exhaust port 105 and an air inlet port 106 , and the exhaust port 105 communicates with the interior of the furnace body 10 . The air inlet 106 communicates with the bottom of the furnace body 10 through an air inlet channel 107 on the rear side 102 of the furnace body 10 . The exhaust port 105 and the air inlet 106 are connected to a pipeline A, the pipeline A is composed of inner and outer pipes A1 and A2, the inner pipe A1 communicates with the exhaust port 105, and the outer pipe A2 communicates with the air inlet 106 .

The body of furnace 10 is provided with a partition 14, the partition 14 includes a partition 141 and two vertical boards 142, the partition 141 is connected to the wall in the furnace 10, and the partition 141 has a The opening 143 , the two vertical plates 142 pass through the opening 143 . 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 corresponding 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 produced by the burner 20 burning gas extends from between the two vertical plates 142 to above the partition plate 141 .

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

The first guiding plate 32 has a first top edge 321 and a first guiding surface 322 , and the second guiding plate 34 has a second top edge 3411 and a second guiding surface 322 , 342 . The first and second top edges 321 , 341 are separated by a distance and parallel to each other, and extend along a direction parallel to the burner 20 . The first top edge 321 is higher than the second top edge 341 . The two guiding surfaces 322, 342 face the second space S2, and a channel 40 is formed between the two guiding surfaces 322, 342, communicating with the first and second spaces S1, S2. The width of the channel 40 in the direction 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, 341 to communicate with the channel 40 and the second top edge. A space S1. The outlet 42 is located directly above the burner 20 and has a long axis parallel to the extension direction of the burner 20, wherein the width of the outlet 42 on the long axis is larger than that of the burner 20 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, 342. . The baffle 38 is fixed on the second top edge 341 of the second guide plate 34 , and is located between the two partitions 36 closest to the exhaust port 105 and corresponds to the exhaust port 105 . The two partitions 36 are left and right symmetrically arranged with the baffle 38 as the center, so that the distance between the two partitions and the baffle is the same.

Please refer to FIG. 5 and FIG. 6 , when the burner 20 burns gas, the airflow of the hot gas generated flows upward from the second space S2, and passes through the outlet 42 along with the two guide surfaces 322 and 342 upward. The air flows into the first space S1 and is discharged outside through the exhaust port 105 . Since the widths of the two guide surfaces 322, 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, reducing the formation of turbulent flow in the second space S2 opportunity, and avoid hot air stagnating in the second space S2, which would cause the temperature of the second space S2 to be too high. When the hot air rises to the first space S1 , the hot air flow is relatively slow, so it can be easily discharged out of the exhaust port 105 .

The 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 , therefore, it will not affect the flow of the airflow above the partition plate 141 . In addition, the baffle plate 38 of the air guiding device 30 is located at the place corresponding to the exhaust port 105, which can block the upwardly rising hot gas from concentrating on the exhaust port 105 in the passage 40, so that the hot gas can pass through the exhaust port 105 in a dispersed manner. Between the partitions 36, the chance of turbulent flow is reduced. The two partitions 36 are arranged left and right symmetrically around the baffle 38 , so that the air passing through can enter the first space S1 from the left and right sides of the baffle 38 on average.

The gas fireplace 200 of the present invention enables the hot gas inside the furnace body 10 to be discharged to the outside smoothly through the gas guiding device 30 having a gas guiding effect, thereby reducing the heat accumulated in the second space S2. Compared with the existing The gas fireplace can lower the temperature of the tempered glass 12 .

The above descriptions are only preferred feasible embodiments of the present invention, and all equivalent changes made by applying the description of the present invention and the scope of the patent application should be included in the scope of the claims of the present invention.
