Abstract
The utility model relates to a labyrinth type multipurpose coal-fired warm air furnace which comprises a furnace base, a furnace outer housing, a furnace door, a furnace disk and a furnace tile. The upper part of the furnace outer housing is provided with a furnace ring, and a labyrinth type annular flue and an annular warm air passage which are mutually spaced. The annular flue is communicated with a chimney, and the upper part of the annular warm air passage leads to a warm air pipe. The lower part of the annular warm air passage is communicated with a warm air chamber which is arranged between the furnace tile and the furnace outer housing, and the lower part of the warm air is provided with an air inlet. The utility model has the efficacy that the utility model can be used for cooking rice and heating, and the labyrinth type annular warm air passage absorbs heat to form warm air for heating rooms. The installation and the use are convenient.
Description
The utility model relates to a kind of coal-fired domestic burners with convection heater, and particularly a kind of labyrinth type is used coal-fired warm air furnace more.
Chinese patent CN2056975U disclosed a kind of " energy-saving multifunctional hot-water heating stove ", mainly form by bell, Lu Quan, top board, water courage, shaft, grate, stove seat and base plate, this stove and accessory has a combustion chamber and the anti-combustion chamber of coal gas, flue adopts the dicyclic structure, can connect radiator by water inlet pipe and water outlet pipe, and have the function of culinary art and heating concurrently.The weak point of this device is, in order to reach the heating effect, must radiator be installed in addition and match with it, and it is higher to purchase and install the expense of radiator, for the user has increased financial burden.
The purpose of this utility model is to provide a kind of labyrinth type to use coal-fired warm air furnace more, by the labyrinth type heat exchanger of setting up in the furnace wall, produces warm braw naturally for heating of house, thereby needn't set up facility such as radiator in addition, can have the function of culinary art and heating concurrently.
Another purpose of the present utility model is to provide a kind of labyrinth type to use coal-fired warm air furnace more, and its structure is comparatively simple, thermal efficiency height, and manufacturing cost is lower and floor space is less.
The purpose of this utility model reaches as follows:
A kind of labyrinth type is used coal-fired warm air furnace more, comprise stove seat, stove outer covering, fire door, fire grate, below fire grate, be provided with grey chamber, the fire grate top is provided with tile, the tile periphery is provided with heat-insulation layer, be provided with the stove circle in periphery, stove outer covering top, stove circle top is coated with stone or metal plate for standing a stove on as a precaution against fire, bell, be formed with flue in this fender, this flue is communicated with the chimney that is located at stone or metal plate for standing a stove on as a precaution against fire top one side, it is characterized in that: this flue is a plurality of annular flues that interconnect, and is formed with the warm braw chamber between stove outer covering and tile and heat-insulation layer thereof, offers the air inlet of this warm braw chamber in the stove outer covering bottom; Also be provided with in described stove circle and the corresponding spaced-apart ring-shaped preheated air inlet of described annular flue, this annular preheated air inlet is connected with the warm braw chamber of described tile outside, and this annular preheated air inlet top communicates with the warm braw pipe.
The purpose of this utility model can also following mode reach, and described labyrinth type is used coal-fired warm air furnace more, can be arranged with the warm braw cover in periphery, described chimney bottom, and this warm braw cover communicates with described warm braw pipe, and this warm braw cover bottom is provided with air inlet.
Described labyrinth type is used coal-fired warm air furnace more, and covering at described stove circle inwall to have heat-insulation layer.
Described labyrinth type is used coal-fired warm air furnace more, can be provided with the fire door that the secondary air road leads to the tile upper end outside described tile and heat-insulation layer thereof, and this bottom, secondary air road is provided with the secondary air mouth.
Advantage of the present utility model mainly is both can heat up water to cook, and also can be used for heating; Carry out heat exchange by being equipped with warm braw passage and burner hearth and flue in the stove outer covering, can produce warm braw naturally, as long as guide to indoor everywhere with the warm braw pipe warm braw, promptly can be used for the heating in a plurality of rooms, installation, extremely easy to use, and can save the expense of purchasing, installing radiator, being particularly suitable for vast town and country does not have the resident of radiator to use.Because adopt labyrinth type annular preheated air inlet and annular flue apart from one another by carrying out heat exchange, heat exchange area is big, thereby has higher heat exchanger effectiveness.In addition, the sheathed again warm braw cover in the chimney bottom can further utilize the waste heat of chimney; Outside tile, set up the secondary air road, can make coal-fired fully burning, improve stove fire temperature.
Illustrate as follows:
Fig. 1 is a kind of preferred embodiment structural representation of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The utility model will be described in further detail as follows in conjunction with the accompanying drawings: see figures.1.and.2.A kind of labyrinth type is used coal-fired warm air furnace more, comprise that grey chamber 20 is formed at stove seat 1, stove outer covering 7, fire door 19, fire grate 2, fire grate 2 bottoms, fire grate 2 tops are provided with tile 3, tile 3 peripheries are provided with heat-insulation layer 4, are formed with warm braw chamber 6 between heat-insulation layer 4 and stove outer covering 7,6 bottoms, warm braw chamber are provided with air inlet 18.Periphery, stove outer covering 7 top is provided with stove circle 10, stove circle 10 tops are coated with stone or metal plate for standing a stove on as a precaution against fire 11 and bell 15, stove circle 10 inwalls have been set up heat-insulation layer 9, form in the stove circle 10 apart from one another by labyrinth type annular flue 101 and annular preheated air inlet 102, annular flue 101 1 ends communicate with fire door 8, and the other end communicates with the chimney 13 that is located at stone or metal plate for standing a stove on as a precaution against fire 11 tops.Annular preheated air inlet 102 upper ends are communicated with a warm braw pipe 17, and annular preheated air inlet 102 bottoms are communicated with warm braw chamber 6.In addition, set up secondary air road 5 at heat-insulation layer 4 outer walls of tile 3, the upper end in secondary air road 5 leads to fire door 8, can improve the fire door ignition temperature to coal-fired supplemental oxygen.Be provided with warm braw cover 14 in chimney 13 bottom outer race, can further utilize the waste heat of chimney 13, warm braw overlaps 14 bottoms and is provided with air inlet 12, its top is communicated with warm braw pipe 17 by transverse tube 16, cold air is inhaled into 6 preheatings of warm braw chamber by the air inlet 18 of warm braw chamber 6, carries out heat exchange through annular preheated air inlet 102 with annular flue 101 again, is further heated, warm braw pipe 17 by top draws toward everywhere indoor again, can be used for the heating in a plurality of rooms.
