In this case, the exhaust guide plates are simply arranged in a staggered manner with their tips slightly protruding from the lower end of the straightening plate, so the headwind flowing down along the front outer cylinder collides with the tips of the exhaust guide plates. Since the exhaust gas flows along the front and back of the exhaust guide plate, the suction and exhaust effect of the exhaust gas caused by the back wind is halved, which impedes the burner's combustibility.Especially, the exhaust gas is suppressed significantly against the back wind of the rear exhaust, causing flame overflow. There were drawbacks such as the occurrence of the following phenomenon.

性の向上を図ったものである。In order to eliminate these drawbacks, this invention provides a headwind guiding piece that is horizontal or slightly upward in front of the horizontal at the lower end of the rectifying plate, and a headwind guide piece that is installed at the front end of the exhaust guide plate installed at the bottom of the headwind guiding piece. By bending the part into a reclining V-shape and providing a headwind guide piece, the headwind is guided to flow forward smoothly, increasing both the suction and exhaust effect of combustor gas and the headwind discharge effect, and inhibits burner combustion. The aim is to improve safety by preventing

案に係るものである。Its structure is such that a rectifying plate 2 is installed inside a baffler outer cylinder 1 so as to be tilted upward in the rear direction, and a back wind guide piece 3 is placed horizontally or with the front side facing slightly upwards at the lower end of the baffler plate 2 outside the baffler. The exhaust guide plate 5 is provided so as to extend close to the front opening 8 of the cylinder 1, and with a certain gap 4 at the bottom thereof, the exhaust guide plate 5 is slightly sloped forward and downward from the horizontal, so that the front end thereof is connected to the back wind guiding piece 3. A back wind guide piece 6 is installed to protrude from the front end, and the front end of the exhaust guide plate 5 is provided with a back wind guide piece 6 whose distal end extension is folded back and upward with respect to the exhaust guide plate 5 to form a reclining V-shape. This invention relates to the invention of a built-in baffler for combustion appliances.

したＶ字状に形成せる逆風案内板６を設けている。One embodiment will be described below based on the drawings. In the drawings, reference numeral 1 denotes a baffler outer cylinder forming an exhaust passage of a heat exchanger etc. (not shown); A rectifier plate 2 is installed in a steep upward slope in the rear direction, and a headwind guiding piece 3 is placed horizontally or slightly upwardly in front of the horizontal at the lower end of the rectifier plate 2 until it reaches near the front opening 8 of the baffler outer cylinder 1. A certain gap 4 is provided in the 1st part of the headwind guiding piece 3, and the exhaust guide plate 5 is slightly sloped forward and downward from the horizontal, so that its front end protrudes from the front end of the headwind guiding piece 3. At the front end of the exhaust guide plate 5, there is provided a back wind guide plate 6 whose distal end extension is folded back and upward with respect to the exhaust guide plate 5 to form a reclining V-shape.

り燃焼廃ガスを吸引放出する。Therefore, the head wind flowing in from the exhaust pipe connection lower flows down along the baffle plate 2 as shown by the arrow a, and extends to near the front opening 8 of the baffler outer cylinder 1, and is directed horizontally or slightly upward in front of the horizontal. The combustion waste gas is guided forward by hitting the back wind guiding piece 3 and flows out forcefully from the front opening 8, and the combustion waste gas is sucked and discharged from the gap 4 due to the flow velocity.

また、バフラ−外筒１に沿う逆風は矢線すにて示す如く

ガスの抑えは全く生じない。In addition, the head wind along the baffler outer cylinder 1 hits the head wind guide piece 6 protruding from the head wind guide piece 3 as shown by the arrow line, is guided forward, and flows out downwardly of the front surface, so that the combustion waste gas is No suppression occurs at all.

従って、逆風の流れを前方へスムースに導いて燃焼室か

有効である。As explained above, this device has a simple structure in which a backwind guide piece is provided at the lower end of the rectifying plate, and the tip of the exhaust guide plate is bent into a reclining V shape to provide a backwind guide piece. The flow of headwind is reliably guided to the front opening side to enhance the headwind exhaust effect, and the headwind is reliably guided forward, which also adds the effect of suction and exhaust of combustion waste gas, suppressing exhaust gas caused by headwinds caused by burner combustion. It doubles safety by preventing interference with air flow, and is particularly effective when implemented in rear exhaust systems.
