The nozzle of the seal groove 11 of pedestal 1 and grey furnace bucket 3, which cooperates, to be sealed, and card slot 12 is connected together with bayonet lock 31, when engaging, Logo slot on pedestal 1 and the logo slot of grey furnace bucket 3 to it is corresponding when bayonet lock 31 and the vertical slot of card slot 12 it is corresponding, push up Grey furnace bucket 3 rotates, and bayonet lock 31 engages with the horizontal notch of card slot 12, at this point, grey furnace bucket 3 is connect with pedestal 1, easy to connect, behaviour Make simple.

Circulation canal 22 is isolated into arcuate structure by stove door plant 25, fire door and 2 connection of liner, and the cold wind of fresh wind is from lower part Air inlet enter after around 21 bottom of partition space cycle, then enter 21 top of partition from the through-hole of the partition other end Space cycle, the cold air after circulation take away partial heat after contacting with the inner wall of liner 2, cold air after heating from The vent on 22 top of circulation canal is discharged, and is introduced into blast pipe 33 through piping, reduces the temperature of inner bladder outer wall, outer wall It can choose the lower material of heat resistance, save cost, grate plate 23 and the consistent plate of 2 internal diameter of liner, which is provided with Perforative air inducing hole after encountering blocking or ablation, can directly take out replacement, easy to maintain.

Exhaust fan 24 extracts fresh air and enters circulation canal 22, and the fresh air after circulating-heating is from blast pipe 33 The environment temperature increased in grey furnace in grey furnace bucket 3 is entered, while increasing the pressure in grey furnace bucket 3, firewood is higher Environment temperature and direct draught burning are more prosperous, and efficiency of combustion is higher；The air inlet of exhaust fan 24 stretches out outside cabinet 6, exhaust fan 24 Wind speed can be conveniently adjusted air volume by Frequency Converter Control, by the burning velocity of air force control firewood.

Hopper 42 and feeding-passage 41 are slidably matched opening and closing, from the upper side of 42 front end of hopper addition firewood, nothing after unlatching It need to pedal down and bend over to operate, after pushing firewood to liner, be locked by retaining mechanism 43, securely and reliably, 42 rear end of hopper connects along plate It is connected to pull handle, when operation is more convenient, is equipped with seal groove along the contact surface of plate and feeding-passage 41, setting sealing in seal groove Item sealing, sealing effect is more preferable, and circulating air will not blowback.

Feeding-passage 41 is connected and fixed with liner 2, stable structure, and the center of liner 2 is goed deep into the front end of hopper 42, is located at material The firewood of 42 front end of case is climbed sharply after igniting from the center of liner 2 upwards.

When adding firewood, firewood is placed directly in the air inducing hole top of 42 front end of hopper, leans to one side to observe firewood without pedaling down Position, more convenient operation, when hopper 42 is in 43 lock state of retaining mechanism, the air inducing hole of 42 front end of hopper and grate plate Air inducing hole on 23 is overlapped, keeps air supply channel unimpeded；When hopper 42 is in locking state, thermal insulation board is interior with liner 2 Wall cooperation sealing, high temperature are conducted by thermal insulation board to thermal insulation separation hot tank 44, to internal object after the air themperature raising of isolation Part is heated, obstruct liner 2 in high temperature be directly conducted to connect with 42 rear end of hopper along plate, avoid excessively high along plate temperature It scalds one's hand.

When locking, the arcwall face of 42 front end of hopper is contacted with the inner wall of liner 2,42 rear end of hopper along plate and feeding-passage 41 contact surface sealing, at this point, the positioning column of retaining mechanism 43 is corresponding with the location hole of 42 side wall of hopper, rotation lid drives bullet Spring compression drives positioning column to pass through the location hole cooperation positioning and locking on feeding-passage 41 and 42 side wall of hopper, securely and reliably, behaviour Facilitate.

Firewood is in the preceding end burning of hopper 42, and flame is climbed sharply upwards from liner 2 and entered in burner hearth 5, with 5 top of burner hearth After the contact of the bottom of a pan, the high temperature fumes of generation roll downwards along bore wall to be entered in busway 51, is rolled upwards and fire again later Flame mixing carries out second-time burning, and the smog after second-time burning enters flue from smoke outlet 52 and is discharged, and makes flammable in high temperature fumes Impurity is reduced, and the second-time burning in flue is avoided to damage, and is avoided smoke outlet from generating Mars and is caused fire.

Heat preservation 63 front end of drawer arcwall face contacted with the inner wall of burner hearth 5, high temperature conduct to keep the temperature drawer 63 in food The firewood in storage bavin drawer 62 is dried in preheating insulation, the temperature of 2 bottom of liner, and feeding device 4 is from firedoor hole 64 and furnace Door 65, which exits, adds bavin, 65 slide opening and closing of fire door, the high temperature being effectively utilized in 5 inner wall of burner hearth and cabinet 6, and bavin is taken to add bavin conveniently, It is easy to operate.

The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model System, the features in the embodiments and the embodiments of the present application in the absence of conflict, can mutual any combination.This is practical new The protection scope of type should be with the technical solution of claim record, technical characteristic in the technical solution recorded including claim Equivalents are protection scope.Equivalent replacement i.e. within this range is improved, also the protection scope of the utility model it It is interior.
