Description
Technical field
The present invention relates to a kind of burner that uses combustion gas or fuel oil, specifically is a kind of combustor depression bar type large and small fire self-control system.
Background technology
In the prior art, most of burner has only big fire and stops working two grades.When the cook during frying pan leaves the combustion flame and goes sabot, washes pot, burner big fire strength is still burnt.Even used the burner with little fire screen, in these cases, the cook also because many times of dish are anxious, has no time to attend to the active adjustment large and small fire.It is empty the burning that burner has time of 50% at least according to field observation! The waste of fuel that the empty burning of burner is brought, problems such as toxic emission are quite serious.As for adopt photoelectric probe to control the scheme of large and small fire on the burner both sides, be not because the mounting condition harshness, exactly because electronic component in the operating mode rugged environment, degenerated by oil smoke, can't operate as normal and restricted greatly.Inadvertent free and the flaring big fire can cause personal injury when the cook takes wiper, spoon particularly.
Summary of the invention
The present invention need overcome the deficiency of manual adjustments, and realizes the big and small fire fluid drive; Also need to overcome the high and reliable inadequately problem of use of mounting condition.
Combustor depression bar type large and small fire self-control system of the present invention, comprise burner, it is characterized in that described burner around (promptly in the orthographic projection scope of frying pan) be fixed with montant, be with motion bar in the montant, between two bars back-moving spring is arranged, the motion bar lower end contacts with touch switch; Be provided with the current limliting magnetic valve in the fuel inlet pipe of burner, series connection is connected with power supply the current limliting magnetic valve with touch switch.Wherein the current limliting magnetic valve is two duties of all-pass and part logical (this flow area can be determined by simple experiment).The structure of vertical tube-motion bar-back-moving spring is being sat frying pan, in time be delivered to touch switch from action, and then realizing the Synchronization Control of big and small fire, and this is an innovative point of the present invention.
In order to satisfy the fiery needs of using weigh pot in the hand, as preferably, touch switch is in parallel with delayer, even still have big fire to use with (as 10 seconds) in the short time that allows behind the frying pan disengaging motion bar.
Another selection of time-delay scheme is, the vertical tube tube wall laterally is provided with damper tube, and the damper rod of band boss is arranged in the damper tube, is with spring on the damper rod, and the other end of spring contacts with the adjusting pressure cap of the damping mouth of pipe, locking nut in addition on the damper rod; The damper rod head withstands the taper damping cover that is with on the motion bar, and taper damping cover top contacts with the boss of motion bar, and the below contacts with back-moving spring.This structure makes the elastic force of spring to adjust, and can lock after adjustment.Because the damper rod head withstands the inclined-plane of taper damping cover, as long as the elastic force of spring is suitable, the rising of motion bar will be damped and delay, and postponed the disengaging with touch switch, to satisfy the needs of weighing in the hand during the pot with big fire.
Also can two kinds prolong a scheme and combine use.
Montant can be set up separately, as preferably, is located on the shell of burner, so that make simple.
Characteristics such as the present invention has structure and installs simply, and large and small fire control is reliable.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention;
Fig. 2 is the structural representation of depression bar assembly of the present invention.
The specific embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
Embodiment 1.See Fig. 1, Fig. 2, the combustor depression bar type large and small fire self-control system that this is routine has an oil burner 1, is fixed with vertical tube 2 on the shell of burner, is with the motion bar 3 of band boss in the vertical tube, and there is pressure cap 2-1 the vertical tube lower end.The motion bar lower end is fixed with conical surface cover 5 by screw 14, and the conical surface of this cover contacts with touch switch (employing microswitch) K1 steamboat, and limited protruding member-nut 13 is arranged at the top of motion bar.Taper damping cover 11 and back-moving spring 4 are enclosed within on the motion bar 3 together, and the top of taper damping cover contacts with the boss of motion bar 3, and the below of back-moving spring contacts with pressure cap 2-1.
See Fig. 1, be provided with current limliting magnetic valve M1 among the fuel inlet pipe 1-1 of burner.Current limliting magnetic valve and microswitch K1 are connected in series on the power supply, and wherein the microswitch two ends also are parallel with delayer SJ1.Touch switch K1 in this example, delayer SJ1 and current limliting magnetic valve M1 are the commercially available prod.
The workflow explanation:
(1), when pressing pot, the motion bar 3 in the vertical tube 2 promotes conical surfaces cover 5 downwards and triggers microswitch K1, conducting current limliting magnetic valve M1, the omnidistance unlatching realized big fire burns;
(2), upwards mention when frying pan, because the time-lag action of lateral damper, motion bar 3 is still being oppressed microswitch K1, and current limliting magnetic valve M1 still remains on big through-flow state, carries out big fire burns (delayer SJ1 can't work this moment).When the delay time of damper was not enough, delayer SJ1 can replenish time-delay as required.Damper, delayer SJ1 also can use with depression bar assembly separate configurations.
(3), served as the time of setting after, current limliting magnetic valve M1 just switches to the logical state of part from the all-pass state, has begun to keep little fire burns.
When stopping using fully, should close ball valve E.
Embodiment 2.The combustor depression bar type large and small fire self-control system that this is routine has only the mechanical type horizontal damper, and microswitch K1 two ends do not have delayer SJ1.All the other are with example 1.
Embodiment 3.The combustor depression bar type large and small fire self-control system that this is routine, there is delayer SJ1 at microswitch K1 two ends, and the mechanical type lateral damper is not arranged.All the other are with example 1.
