Description
Technical field
The utility model relates to a kind of heating stove for civilian use, particularly a kind of return air oven.
Background technology
Existing air return stove also has the pattern of band baking box, is provided with separately but the baking box of existing air return stove is many, and overall volume is bigger; Structure is complicated; And adopted the pattern that narrows down gradually between from the body of heater to the chimney, difficulty of processing is big more, and ignition or return air effect are undesirable.
Summary of the invention
The utility model technical problem to be solved provides a kind of return air oven, is convenient to processing, and compact conformation can make full use of the heat of fuel.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of return air oven comprises body of heater; Be provided with the wood stove thorax in the body of heater, be provided with grate in the wood stove thorax, charging aperture passes body of heater and is communicated with the wood stove thorax; The body of heater below is provided with base, is provided with ash bucket in the base, and the body of heater lower end also is provided with the air inlet that is communicated with the wood stove thorax; Body of heater one side is provided with smoking box, and smoking box is communicated with chimney;
Be provided with baking box in the smoking box, form the ignition flue between the top of baking box and smoking box, form the return air flue between the bottom of baking box and smoking box and the side.
Be provided with ash-draining gate between described base and the body of heater.
Described smoking box is provided with sewage door.
Be provided with the ignition door in the described ignition flue.
Be provided with the coal stove thorax in the described wood stove thorax.
Described baking box is adjacent to the wood stove thorax.
A kind of return air oven that the utility model provides through adopting above-mentioned structure, can make full use of the heat after the fuel combustion, and heat is evenly distributed on body of heater.The utility model compact conformation, profile is upright, is convenient to processing.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the overall structure sketch map of the utility model.
Among the figure: body of heater 1, fire-sealing ring 2, wood stove thorax 3, coal stove thorax 4, ignition door 5, ignition flue 6, baking box 7, chimney 8, charging aperture 9, air inlet 10, ash-draining gate 11, ash bucket 12, base 13, smoking box 14, return air flue 15, grate 16, sewage door 17.
The specific embodiment
A kind of return air oven comprises body of heater 1, is provided with wood stove thorax 3 in the body of heater 1; Be provided with grate 16 in the wood stove thorax 3, charging aperture 9 passes body of heater 1 and is communicated with wood stove thorax 3, and body of heater 1 below is provided with base 13; Be provided with ash bucket 12 in the base 13; Body of heater 1 lower end also is provided with the air inlet 10 that is communicated with wood stove thorax 3, and body of heater 1 one sides are provided with smoking box 14, and smoking box 14 is communicated with chimney 8; Existing air return stove is many from ash bucket 12 air intakes, uses inconvenience, and the utility model is extra has increased air inlet 10 newly, and has increased the cross-sectional area of air inlet 10 on the basis of existing technology, thereby has improved the efficiency of combustion of fuel.
Be provided with baking box 7 in the smoking box 14, form ignition flue 6 between the top of baking box 7 and smoking box 14, form return air flue 15 between the bottom of baking box 7 and smoking box 14 and the side.Described baking box 7 is adjacent to wood stove thorax 3.Adopt above-mentioned structure, overall structure is more compact, and profile is upright; Be more convenient for processing; And the flue gas during burning can only be drained into chimney 8 from return air flue 15 then from descending near the passage of charging aperture 9 one sides between body of heater 1 and the wood stove thorax 3, thereby guarantees that heat is evenly distributed on body of heater 1.
In the optional scheme, be provided with coal stove thorax 4 in the described wood stove thorax 3, coal stove thorax 4 adopts the material of fire clay to process, and is placed on during use on the grate 16 of wood stove thorax 3, directly can adopt coal to act as a fuel, thereby increase the applicability of the utility model.
Be provided with ash-draining gate 11 between described base 13 and the body of heater 1, be used to discharge the ashes in wood stove thorax 3 or the coal stove thorax 4.
Described smoking box 14 is provided with sewage door 17, carries tar and a large amount of dusts in the flue gas after the fuel combustion, and the position that deposits the most easily is exactly the bottom of smoking box 14, so the utility model is provided with sewage door 17 in the bottom of smoking box 14, in order to blowdown.
Be provided with ignition door 5 in the described ignition flue 6.When getting angry, open and get angry door 5, the flue gas of burning is turned back directly to get into through fire-sealing ring 2 and is got angry flue 6 and enter chimney 8, is beneficial to pilot fuel like this, after igniting fully, closes and gets angry door 5.The flue gas of burning is drained into chimney 8 through return air flue 15, heats whole body of heater 1.
