Description

Household self controlled stove

The utility model belongs to the improvement of home furnace, is a kind of cooking stove that is used for controlling automatically stove keying and programming rate speed specifically.

Existing automatic control cooking stove generally adopts air inlet system once or twice, and the programming rate of this coal stove is slower, in case the air intake duct is blocked, programming rate promptly is affected, and the burning of fuel is also incomplete.Its employed fuel is more single, can only burn honeycomb briquette, and coal gas is more serious to the pollution of surrounding environment.Because the uncontrollable programming rate of automatics, therefore be difficult to grasp the required duration and degree of heating, and also easy break-down of controlling organization.

The purpose of this utility model provide a kind of simple in structure, fault rate is low, can automatic open close the family expenses automatic control cooking stove of fire door and control stove programming rate.

Another purpose of the present utility model is to design can not only burn honeycomb briquette, and can burn the coal that looses, pluralities of fuels such as timber, and can reduce the family expenses automatic control cooking stove of environmental pollution.

Solution of the present utility model is: a pair of air door is housed on air intake passage, have upper and lower hole, garden of staggering mutually on the air door, throttle linkage is connected with air door respectively, and brake bar contacts with throttle linkage, air blast is installed on the air intake passage mouth, its air quantity adjustable size joint.Electromagnet is fixed on the corresponding position, brake bar upper end,, controls the upper and lower motion of throttle linkage by brake bar by the automaton that electromagnet, adjustable thermal relay, timer constitute.

Be an embodiment of the present utility model below, be described further in conjunction with the accompanying drawings:

In this example, be equipped with in the body of heater (6) two can be nested together and knock-down combustion chamber (10), combustion chamber (10) around be the refractory layer (8) that a circle is made up of heat proof material, in the outside of refractory layer (8) is thermal insulation layer (9), and gathering-device (7) has surplus heat between body of heater (6) and thermal insulation layer (9).Have on the cover plate (1) and the identical hole, garden of ash discharging passage (3) size, have one under it and connect grey container, spring (2) one ends link to each other with cover plate (1), and the other end is connected on the ash discharge gate (4), its effect is to compress ash discharge gate (4) and connect grey container, prevents that air from leaking in the stove.

The support (23) of automatics is fixed on the outside of body of heater (6), air door passage (26) is fixed on the fire door, its fixed form can connect or directly insertion with bolt, original passage and air door passage (26) by fire door constitute air intake passage (5) together, a pair of air door (24,27) is set on air intake passage (5), have upper and lower hole, garden of staggering mutually on it, its size is consistent with air intake passage (5).Throttle linkage (16,20) links to each other with air door (24,27) respectively, it can be done in garden shape sleeve (15,19), following motion, brake bar (17,21) bottom is passed garden shape sleeve (15,19) and is contacted with throttle linkage (16,20), on throttle linkage (16,20), have breach or hole, garden, when throttle linkage (16,20) was up, the bottom of brake bar (17,21) entered breach and pins throttle linkage, and it is not glided.Electromagnet (18,22) is fixed on brake bar (17,21) the corresponding position, upper end, and the brake bar upper end should be done consistently with the adhesive face of electromagnet (18,22).Air blast (25) is contained on air door passage (26) mouth, and link to each other with key switch (K2), between air door (27) and air blast (25), microswitch (K3) is housed, timer (30) and electromagnet are connected to three-way switch (K5) between (18,22), and it is made of K51, K52 and K53.

Device for eliminating smoke and dust (33) is to be made of collection dirty container (35) and condenser (37), and the two is overlapped, is fixed with screw, and a metal sleeve (34) is arranged at the bottom that collects dirty container (35), and it is enclosed within on the chimney (32).

Use this cooking stove, elder generation's power turn-on switch (K1), throttle lever (28) is upwards pushed away, contactor contact (14) is connected, electromagnet (18) energising back produces attraction, holds the upper end of brake bar (17), and this moment, throttle linkage (16) was pinned in the bottom of brake bar, air door (24) is not glided, and the air intake path opens wide.When promoting throttle lever (28), also throttle lever (29) is upwards pushed away, because of having the hole, garden on the air door (27), air intake passage (5) staggered fully with the hole, garden on the air door (27) when air door (27) was up, the air intake path blockade, the air intake path is opened when descending, throttle lever (29) drives air door (27) and moves upward, and makes the air intake path be in closed condition.Timer (30) transfers to the required time, plug (13) insertion is contained in the connecting hole of the adjustable thermal relay (12) on the pot cover, adjustable thermal relay is made up of two silicon steel sheets, by regulating the adjustable required temperature of screw on it, temperature regulating range (50 ℃～105 ℃) is dialled three-way switch (K5) to the right, this moment K51, K52 disconnects, when timer (30) is gone between institute's timing, the control circuit of timer disconnects, electromagnet (22) loses its reliss because of outage, the breach of throttle linkage (20) is left in the bottom of brake bar (21), and air door (27) glides under the effect of self gravitation voluntarily.The air intake path is opened, and the downslide of air door (27) makes microswitch (K3) conducting, and air blast (25) is started working, and presses key switch (K2) according to institute's required airflow in front of the door in blow-on.When meal is ripe, the circuit of adjustable thermal relay (12) disconnects, electromagnet (18) loses its reliss because of outage, air door (24) glides voluntarily, the air intake path blockade, air blast also quits work simultaneously because of power supply disconnects, the utility model also can be closed with timer (30) control air door (24), only needs three-way switch (K5) is dialled to the left side, makes K51, the K52 closure, K53 disconnects, electric current flows to electromagnet (18) by timer, and during the timer time to go, its control circuit disconnects, air door (24) is closed, under the situation of no alternating current, (K4) beats to the right with the alterating and direct current change-over switch, gets final product work, as be reluctant to use automatics, available hand switch (K6).

Burn loose coal or bavin standing grain with this cooking stove, only need on the port core retainer plate, fuel can insert from kitchen range door (11) at any time.Cook the meal of a family of five, burn the coal that looses as long as 0.15 kilogram, burn 0.2 kilogram of bavin, taking with pressure cooker is 8 minutes, ordinary pan is wanted 10 minutes at most, owing to air blast is housed at the air intake passage road junction, make the ratio of combustion of fuel more complete, in chimney (32), discharge flue dust, pernicious gases such as sulfur dioxide, enter 4 exhaust passages (36) in the dirty container of collection (35), waste heat makes the water of storing in collection dirty container (35) groove vaporization of being heated, steam in uphill process with flue dust, chemical reaction takes place and generates solable matter in pernicious gases such as pernicious gases such as sulfur dioxide mix, sulfur dioxide and steam when rising, when rising to condenser (37), steam is met cold liquefaction, is attached to the flue dust on the steam and the product of pernicious gas and discharges thereupon, reduces the pollution to environment.

The utility model compared with prior art its advantage is: simple in structure, and failure rate is low, intensification speed is fast and can regulate intensification speed, AC/DC, when economizing fast, power consumption low (power consumption in every month 0.6～0.9 degree), environmental contamination reduction.
