The entire outside of the combustion chamber 3 is covered with a combustion chamber cover 4, the heat radiating cylinder 2 is directly attached to the combustion chamber cover 4, the tip of the exhaust pipe 5 is located inside the heat radiating cylinder 2, and high temperature combustion is performed. The gas flows through the central portion of the heat dissipation tube 2. Further, fresh air is supplied to the gap between the combustion chamber cover 4 and the combustion chamber 3 and flows into the heat radiation pipe 2 through the gap between the heat radiation pipe 2 and the exhaust pipe 5, so that the high temperature gas blown out from the exhaust pipe 5 is the heat radiation pipe. 2 It became difficult to touch the wall surface, and the combustion chamber cover 4 and the heat dissipation tube 2 could be kept at a low temperature.

いる。[Embodiment] The structure will be described with reference to the drawings showing an embodiment. A is a frame of a heater with a heat insulating plate 7 such as an aluminum plate stretched inside, and a moving caster 8 is provided at the bottom for convenience of use. Attached. Reference numeral 1 is a burner provided in the frame A, and the figure shows a pressure spray pot type, but when other burners are used, gas or oil can be used as fuel. A combustion chamber 3 and a combustion chamber cover 4 that covers the entire outside of the combustion chamber 3 are attached to the upper portion of the burner 1, and a combustion chamber provided on the side of the burner 1 is provided in the gap between the combustion chamber 3 and the combustion chamber cover 4. A part of the wind of the fan 9 is forcedly sent through the passage 10. Two
Is a radiating cylinder configured in a serpentine shape so as to circulate the combustion heat of the burner 1, one end of which is attached to the connection port of the combustion chamber cover 4, and the end of the exhaust pipe 5 of the combustion chamber 3 is opened into the radiating cylinder 2. ing.

る。The heat radiating cylinder 2 is composed of a plurality of direct heat radiating pipes 2a arranged in the lateral direction and a bent pipe 2b connecting the ends of the direct heat radiating pipes 2a. 2 is formed in a serpentine shape. The bent pipe 2b of the heat radiating cylinder 2 is a part that changes the direction of high temperature combustion gas.
2b part becomes high temperature, especially immediately after the bent pipe 2b (bent pipe 2b for connecting to the next direct heat radiation pipe 2a) becomes high temperature, and the bent pipe 2b
The direct radiating pipe 2a following is also heated to a high temperature. For this reason, an orifice 6 for reducing the diameter of the conduit is provided near the connecting portion between the bent pipe 2b and the direct heat radiation pipe 2a. The orifice 6 is effective in lowering the temperature of the bent pipe 2b and the direct heat radiation pipe 2a, but when the inner diameter of the orifice 6 of the bent pipe 2b on the burner 1 side having a high temperature is made small, the high temperature combustion blown out from the orifice 6 Direct radiation pipe for gas
As it flows in the central portion of 2a, the temperature rise of the heat radiating cylinder 2 can be prevented, and the whole is heated uniformly. Reference numeral 11 denotes an exhaust outlet in which the final portion of the heat radiating cylinder 2 is projected outside the frame A.

で、バーナ１に近い部分であっても燃焼室カバー４や直
放熱管2aは異常な高温にならない。When the burner 1 burns the fuel, first, the high-temperature combustion gas and the flame are sent to the combustion chamber 3, and the higher-temperature combustion gas is discharged from the exhaust pipe 5 into the heat radiation tube 2. On the other hand, a part of the combustion air supplied to the burner 1 is sent through the passage 10 into the gap between the combustion chamber 3 and the combustion chamber cover 4, and then reaches the outside of the exhaust pipe 5 (that is, the outside of the hot combustion gas), It is sent into the heat dissipation tube 2. Therefore, the outside of the combustion chamber 3 which becomes high temperature and the outside of the high temperature combustion gas in the heat radiating cylinder 2 are covered with a layer of fresh air having a low temperature. The tube 2a does not have an abnormally high temperature.

ことができた。The curved pipe 2b that changes the direction of the gas flow easily comes into contact with the high-temperature combustion gas and tends to reach a high temperature, but the curved pipe 2b is bent by the orifice 6 attached near the connection between the curved pipe 2b and the direct heat radiation pipe 2a. Since the high temperature gas flowing through the pipe is guided to the center of the pipe and blows out to the center of the direct radiating pipe 2a, the abnormal temperature rise of the radiating cylinder 2 can be prevented. Since the temperature rise of the heat radiating cylinder 2 near the burner 1 is prevented, the heat is radiated to the heat radiating cylinder 2 near the exhaust outlet 11 and the heat radiating cylinder 2 is uniformly heated, so that the entire heat radiating cylinder 2 radiates heat rays uniformly. I was able to use it for heating.

個所に設けても良いものである。Since an ordinary heater uses a hot air fan for a heat exchanger, heat is not appropriately exchanged from the burner and the heat radiating cylinder, and the equipment does not locally overheat. Therefore, there are some parts that overheat. In the present invention, the surface temperature of the combustion chamber cover 4 near the burner 1 and the heat radiation tube 2 can be lowered by the structure of the combustion chamber cover 4, the exhaust pipe 5 of the combustion chamber 3, the structure of the orifice 6 of the bent pipe 2a, and the like. done. In addition, the exhaust gas goes straight and the bent pipe 2b of the heat dissipation tube 2
When coming to and changing the traveling direction, exhaust heat tends to overheat the outlet of the bent pipe 2b, but the orifice 6 provided immediately after the bent pipe 2b corrects the exhaust flow toward the center,
It has come to be useful for lowering the temperatures of 2b and the direct radiating pipe 2a.
Since the surface temperature of the heat radiating cylinder 2 decreases as it goes forward,
The orifice is unlikely to impair the performance of the instrument if it is provided in the first bent tube 2b, but the orifice may be provided at a plurality of locations by gradually increasing the inner diameter.
以上のように、温風ファンを用いない暖房機の局部過熱
を防止する本案考案は有用なものである。As described above, the present invention for preventing local overheating of a heater that does not use a warm air fan is useful.
