Description

A kind of gas cooker with float flame of high energy-saving environment protection

Technical field

The present invention relates to a kind of gas cooker with float flame of high energy-saving environment protection, belong to the gas kitchen ranges field.

Background technology

Own household gas range prior art so far, for satisfying the rate of the catching fire technical indicator of product national standard, on its plug valve be: when the counterclockwise left-handed plug valve of preceding pressure knob is lighted a fire always, that is be that plug valve is in the 90 degree mechanical angle zones, be to be in the large and small quirk big fire burns of air feed simultaneously, continue left-handed plug valve subsequently again and enter its 90 to 180 degree mechanical angle when zone, just become to have only the little fire burns of little quirk air feed, after food to be heated is finished, close in the air feed process at the dextrorotation plug valve, get back to big fire burns by little fire again and close flame-out at last.

At the gas-cooker of prior art band combustion chamber, it has nearly 60% combustion gas after tested, does not participate in direct heat food and by having been wasted, so there were many float-flame burner technology to disclose on patent documentation in recent years.But because the inherent characteristic of float-flame burner, fit on the plug valve of prior art and use, will be created in and open float-flame burner burning or in combustion process, in case the pan of moving away will flame from the mortality defective of putting out, but also be difficult to realize the adjusting of little fire burns.Therefore in the technical scheme of these float-flame burners, all unavoidable above the float-flame burner nozzle, be equipped with volume and all little many small-sized combustion chambers of thermal capacity than the combustion chamber of prior art, though they are named different: such as damping combustion chamber, whirlwind cover chamber, returning fire plate or the like, but role unanimity, even flame in these chambers, the burning of cover, plate place, rather than the directly floating base burning that is attached to pan.Because the combustible loss of these little volume combustion chambers is also corresponding less, but do not wait than the large-scale combustion chamber gas-cooker of prior art also solar term 10% to 30%, but because of the very little small combustion chamber of these thermal capacity, cannot stand the dry combustion method of thermal-flame and be directed at and burn, though, all can't implement to change into practical gas-cooker commodity so they can save combustion gas.

Summary of the invention

The objective of the invention is: provide a kind of and opening plug valve when igniting, or in combustion process, no matter having on the kitchen range denys heated pan, and combustion flame can both keep and flame-out; And guaranteeing of can large and small flame can both regulating implements to conform to the gas cooker with float flame of the high energy-saving environment protection of the household gas utensils national standard revised edition that is about to promulgation.

For achieving the above object, when at first the band thermocouple blowout protection plug valve that prior art is used is worked, to greatly, the air feed of little fiery blow vent carries out substantial improvements in proper order: be about in the habitual so far always preceding 90 degree mechanical angle zones of opening plug valve of prior art, in the time of to igniting blow vent air feed, also to greatly, little fiery blow vent is air feed simultaneously, now change in igniting blow vent air feed, only to little fiery blow vent air feed, and to when 90 degree of plug valve are to 180 degree mechanical angle zones, former to little fiery blow vent air feed, only now change into to big fire blow vent air feed or in design during than the specified heat flow of large-scale combustion device, can be simultaneously to greatly, little blow vent air feed; Next except that the essential pan bracket and thermocouple temperature sensor that is provided with, no longer is provided with any and floating inconsistent device of attached flame above burner nozzle.

After above-mentioned binomial improvement design, no matter open plug valve during no pan on kitchen range, the pan of still moving away in burning heating process, the combustion flame flame that can both become to light up is suspended in the top of burner nozzle, after putting pan this moment, will form the floating floating attached flame that is attached to the bottom of a pan of band base of a fruit petioliform.This has just guaranteed the high energy-conservation special domestic animal of solar term more than 50% of float-flame burner, has simultaneously also saved heat time heating time greatly, also since its fully burn and reduced the discharging of CO, the comprehensive superiority of environmental protection again when demonstrating fully its energy-conservation, joint; According to the aim of fully saving existing resource; band thermocouple blowout protection plug valve with this substantial improvements; connect the big parts that this float-flame burner is formed by steam line; just but the utmost point is easily to the gas-cooker of prior art; carry out both high energy-saving environment protections; have the upgrading of flame-out safeguard protection again, thereby produce great social benefit! Compared with prior art, it has also that structure and manufacturing process are simple, materials are more economized, the high performance-price ratio of longer service life.

The concrete real method of revolving

For making full use of the resource of prior art; preferred version of the present invention is a band thermocouple blowout protection plug valve of selecting blowout protection magnetic valve of the prior art and the same axle center of plug valve for use; carry out the substantial improvements of air feed order; only need mutual alignment this moment to the valve body and the venthole on the cone valve core body of plug valve; do simple change and just can realize, and blowout protection magnetic valve and igniter are not done any change.See accompanying drawing 1.: illustrated taper valve core body position is the position when being in plug valve and closing (be plug valve 0 degree mechanical angle).Current pressure and left-handed (being rotated counterclockwise) plug valve, when making plug valve cone valve core body (2.) enter 0 to 90 degree mechanical angle zone, cone valve core body gas outlet (2. at this moment.1.) with valve body (3.) on little fiery gas outlet (3..1.) be involutory, the igniting push rod backs down igniting the gas outlet time, and also interlock is backed down the electromagnetism valve actuation and inhaled iron push rod (1.), and the axially extending bore that combustion gas this moment just enters cone valve core body (2.) (2..3.), the one curb axially extending bore (2..3.) enter the igniting gas outlet and use gas, and another road just by cone valve core body gas outlet (2. for igniting.1.) enter on the valve body (3.) little fiery gas outlet (3..1.), left-handed when making cone valve core body (2.) enter 90 to 180 degree mechanical angles zones for little fiery passage burning gas as continuing again, this moment cone valve core body gas outlet (2..1.) just with valve body (3.) on the big fire gas outlet (3..2.) be involutory, and only for big fire passage burning gas.Certainly when the specified heat flow gas-cooker of the bigger burner of design, can be on cone valve core body (2.), (2. apart from cone valve core body gas outlet.1.) 90 degree mechanical angles (promptly among the figure shown in the dotted line hole) positions, back increase a cone valve core body gas outlet (2..2.), come simultaneously for little fiery passage burning gas.

Owing to press thermocouple blowout protection plug valve working specification regulation; in preceding pressure and left-handed when opening plug valve, must keep above preceding pressure in 4. seconds, with support level fire burns air feed; the thermoelectric force that thermocouple is produced, the magnet valve that is enough to power hold moving suction iron and open combustion gas for mouth.This shows that the present invention is to the substantial improvements of thermocouple blowout protection plug valve air feed order, is the lighting rate performance indications that at all can not influence it.

In the accompanying drawing 2., thermocouple temperature sensor (1.) spacing directly over the little fire-fighting mouth of burner (7.), to guarantee in the burning of the candle flame of no pan and the floating attached flame of band base of a fruit petioliform when pan is arranged when burning, its flame base can both guarantee to the head of thermocouple temperature sensor (1.) effectively heating determine that this can be easily guaranteed by the fixed connection apparatus of thermocouple temperature sensor (1.).Burner big and small fire nozzle (6.), (7.) are made of burner nozzle seat (3.) installs with axis body, and respectively by the nut that is tightly connected (2.) on big and small fire tube connector (5.), (4.) other end, become to be tightly connected with large and small gas outlet connector (5.), (4.) on the plug valve valve body (3.) on the accompanying drawing 1., so just can finish the combiner of specified features of the present invention.Because the unified standard installation dimension of the band thermocouple blowout protection plug valve of the prior art selected for use, thereby but the utmost point easily to the gas-cooker of prior art, carry out not only high-efficient energy-saving environment friendly, but also satisfy the replacement upgrading of flame-out automatic safe protective.

As long as the venthole size on the good large and small gas outlet of rational design configurations connector (5.), (4.), with fumarole size and the number on burner big and small fire nozzle (6.), (7.), just can implement the product conversion of gas cooker with float flame of the high energy-saving environment protection of different gas sources.
