Description

Full-automatic electric coal furnace

The utility model relates to a kind of coal furnace of electrified automatics that uses and burns in the coal apparatus at family expenses, also there are not a kind of high kitchen range that modern city and towns resident family uses that are suitable for, the not young sight of their profiles, insufficiency, the thermal efficiency is low, flammable pernicious gas combustion not exclusively, be unfavorable for health, unclean health, cook cook must other etc. problem, many people have done improvement aspect coal stove, but similar basically; Though some people has done breakthrough reform, because technology is immature or sheerly conception, can not put goods on the market enters family's use at all.

The new purpose of this practicality just provides a kind of electrified automatics of utilizing.Adopt electronic timing automatic blow-on and steam to condense into distilled water and close stove automatically, the coal fired stove of band shower.

The utility model is achieved by the following technical solution:

A sealed annular heat water tank is equipped with near kitchen range face place in top at stove, and a combustion chamber that four secondary air roads itself are arranged is arranged in the water tank, and there is the air inlet of a tubular water tank bottom center.When coal combustion, constantly produce the heat radiation energy, radiant energy is on every side absorbed by the water in the water tank, has heated water, is used for carrying out shower and washes one's face etc.To radiant energy preheating that the bottom produced water tank bottom air, along with burner hearth burning exhausting, the hot-air band enter.The air major part of entering enters burner hearth and coal combustion, and little portion enters four secondary air roads, heating rapidly, and through fire door participates in burning once more from the unburned carbon monoxide that burner hearth comes, and make it sufficient combustion, thereby firepower is more prosperous.Automatically blow-on is: electronic device when empty is housed in the kitchen range bottom, and connects circuit with a coil electromagnetism iron, during timer work, electromagnet produces magnetic force, and turning cylinder to the electromagnet of " T " font is held.When the time that timer is covered defined, the electric current disconnection, electromagnet magnetic disappears, and " T " font starts the bottom of axle bump tape spool fire door, causes its rotation, opens fire door.The principle of closing stove automatically is: covering a cup-shaped vapour cover on the limiting valve of pressure cooker, a rubber tube is connected with it, a condensation metal tube is connected with rubber tube again, when the steam of pressure cooker is discharged in the vapour cover, and enters sebific duct, during through the condensation metal tube, condense into distilled water, splash in the carbonated drink spoon of tape spool fire door, when reaching constant weight, the carbonated drink spoon falls, and causes that the tape spool fire door rotates and the pass stove.Automatically ash discharge is: the air intake tube is vertical with burner hearth, and diffusing ash drops on the fire door, and along with opening of fire door, diffusing ash will be fallen in the beneath ash-pan of kitchen range automatically.

Advantage of the present utility model is that the process of cooking is full-automatic, and thermal efficiency height, but the shower of heat supply water are a kind of desirable coal furnaces.

Further describe the utility model below in conjunction with accompanying drawing.

Accompanying drawing 1 is the whole cutaway view of coal furnace.

Accompanying drawing 2 is controlling organization schematic diagrames

Stove outer covering (18) and boiler face (15) all sheet metal are made, it is recessed to combine with cast iron plate (4) that boiler face hits exactly into figure, one four hole secondary air road combustion chamber (16) is arranged under it, around the combustion chamber is sealed annular water tank (20), it on it hot water outlet (5), it is down cooling water inlet (8), there is a vertical air intake tube (23) the water tank bottom center, between combustion chamber and water tank, filled insulation material (21), the insulation material of bottom can not block combustion chamber secondary air road (22), and water tank is peripheral with sponge (19) insulation.The air inlet (25) of control air quantity when one side of air intake tube has a rectangular pass stove, control air-valve (24) have an iron wire to be connected with the fiery cross axle of control (28) upper end thereon, and the lower end is connected with antiskid bar (12), to prevent to close the fiery time control air-valve of stove control whereabouts.It below the air intake tube tape spool fire door (27), the fire door other end is carbonated drink spoon (30), form leverage with fire door, also has a up big and down small fan-shaped metallic plate on the fire door axle, pendulum (26) on it, the bottom (29) is automatically during blow-on, " T " font starts axle (10) the bump bottom that falls, and the gravity of going up pendulum self when the tape spool fire door forwards certain angle to strengthens gradually and draws close part rack (6) toward this head of fire door.When closing stove automatically, steam from pressure cooker (3) pressure limiting valve (2) discharge, knot vapour cover (1), rubber tube (14) and condensation metal tube (17) carbonated drink of congealing into, splash in the carbonated drink spoon, when a certain amount of, make it and the rotary furnace door-hinge, outwell gravity that at this moment carbonated drink go up pendulum gradually toward this increasing of carbonated drink spoon, make fire door live in air duct in tightly.Electronic timer (11) can connect alterating and direct current, has circuit and line chart electromagnet (7) to connect, and plaing a part is automatic blow-on surely.An ash-pan (31) is arranged at the kitchen range bottom, and fire door is made a call to a blow-on ash can fall into ash-pan automatically.

Specific operation process: rice washed in a pan put into pressure cooker, close the lid, put pressure limiting valve, cover Shanghai Automobile Factory's cover more thereon, the method that the people cooks at family expenses is stayed out with the method for steamed rice.Time switch is gone to time of required blow-on, then " T " font is started axle and turn round, when timer is covered official hour, start axle and fall, fire door is rushed open, after meal is ripe, by the gravity effect of distilled water fire door is lost automatically and close to being held by electromagnet.Fire door also can directly be carried out with hand.Control intake when closing fire, directly twisting " ten " word control fire axle.Ash-pan places at the bottom of the kitchen range, and the ash that looses is fallen into ash-pan automatically with blow-on.

Use the utility model can accomplish to cook base to cooking automation, reduce labor intensity, make full use of waste heat, very convenient with hot water, burning has reduced pollution fully, and ash discharge makes indoor clean hygiene automatically.
