Abstract

The present invention relates to an energy-saving gas range for catering industry, which is formed by the connection of a spray head device fixed on a spray head seat of a range bottom plate and a gas inlet pipe on a gas switch. The present invention also comprises a control switch fixed on the range and a cover which is fixed on the spray head seat and is provided with a sealing ring, wherein the spray head device is composed of a main spray head and an auxiliary spray head, which are communicated with each other and are communicated with the gas inlet pipe. The spray head is formed by that a main nozzle and a nozzle frame are connected into integration and are matched with a valve core with a spring, a valve pocket, a sealing ring and a nut, and the sealing ring auxiliary spray head is formed by the connection of an auxiliary nozzle tightly sheathed with a screw sleeve and a nozzle frame with a sealing ring. The valve core is connected with a pull rod on the control switch, and one end of the pull rod is fixed on the cover. When a cooker is taken away from the range, the flames of the main spray head are entirely extinguished; when the cooker is returned to the range, the flames are ignited immediately because of the existence of the auxiliary spray head. The present invention has the advantage of high speed and can not affect a cook' s work, and the energy saving effect of the whole combustion process can be obviously as high as 52 percent, so the present invention is an ideal product for replacing old products in catering industry.

Description

Energy-saving gas fuel stove for restaurant

Technical field

The present invention relates to a kind of gas-cooker, particularly a kind ofly suit, the local energy-saving gas fuel stove for restaurant that use such as hotel, dining room, dining room in the restaurant.

Background technology

The patent No. 03268785.0 " gas-cooker " is though the gas-cooker that also provides a kind of suitable catering industry to use, it is according to the characteristics of catering trade, during the cooking operation, need the frequent cooker of changing difformity, difference in functionality, this patent has solved and has made the distance that remains setting between cooker bottom and burner firn-jet head, heat energy is fully used, reduces the consumption of combustion gas.But its energy-saving effect is remarkable not enough.

The patent No. 200420048277.3 " gas cooker energy saving device ", a kind of energy saver of installing and using on various types of gas kitchen ranges of suiting is provided, but only having when cooker is taken from flame, it can close flammule automatically, flame recovers automatically when cooker is put back to kitchen range again, need not use hand adjustment gas fuel saving kitchen range switch, function easy to use.Though can save some energy but its complex structure, cost height, need Electric air valve, blower fan, magnetic valve, sensor etc. are installed on air inlet pipeline, also need power supply work automatically.

Summary of the invention

Technical problem to be solved by this invention is: a kind of energy-saving gas fuel stove for restaurant is provided, not only have to take and extinguish fully from kitchen range flame when cooker, when the cooker function that kitchen range flame automatically recovers of resetting back, and it is easy to use, and gas-cooker is in whole use, sufficient combustion, heat energy is fully used, and energy-saving effect is remarkable.

The present invention addresses the above problem the technical scheme that is adopted: energy-saving gas fuel stove for restaurant, be connected institute with air inlet pipe on the burnt gas switch and constitute by being fixed on ejecting device on the kitchen range base plate nozzle boss, also comprise the gauge tap that is fixed on the kitchen range, be fixed on the cover plate that has sealing ring on the nozzle boss, described ejecting device is by the main jet head, secondary shower nozzle is formed, main, secondary shower nozzle communicates and communicates with air inlet pipe, described main jet head is linked into an integrated entity by main burner and main burner seat and is with spring, valve pocket, sealing ring, the spool cooperation of nut is formed, described secondary shower nozzle is connected institute by the auxiliary jet that tightly is with swivel nut with the auxiliary jet seat of band sealing ring and forms, spool is connected with pull bar on the gauge tap, and an end of pull bar is fixing on the cover board.

Compared with prior art, the invention has the advantages that: this energy-saving gas fuel stove for restaurant, directly by cooker take from the operation of putting back to kitchen range, just can realize controlling flame burning automatically and extinguishing by gauge tap, do not need power supply, easy to use.And gauge tap is simple in structure, only is made of pull bar, depression bar, briquetting, easily making, low, the long service life of cost.When cooker was taken from kitchen range, main jet head flame was not to turn down but all extinguish, so combustion gas is saved at most, put back to kitchen range when cooker and exist because of secondary shower nozzle is arranged, flame is lighted again at once, and speed is fast, can not influence cook's work, because of a plurality of air admission holes are arranged on the main burner, combustion gas is fully burnt again, heat makes full use of, also be energy-conservation in whole combustion process, than the former food and drink gas-cooker that major and minor shower nozzle is not installed, energy-conservation after tested up to 52%, be the ideal product that catering trade updates.

Description of drawings

The specific embodiment

Embodiment is further described the present invention below in conjunction with accompanying drawing.

Gauge tap 16 is fixed with the pull bar 11 usefulness nuts that are enclosed within the depression bar end respectively by depression bar 10 two ends of band cover 9, flexibly connects with the briquetting 8 usefulness bearing pins that are clamped in depression bar top end opening place and is integral formation.

Main jet head 5 is threaded with main burner seat 19 by main burner 20 and is integral, cooperate with the spool 15 of band spring 17, valve pocket 26, sealing ring 27, nut form, main burner 20 is the middle hexagon that small through hole is arranged, and there are 6 through holes the following peripheral, and upper periphery has two large through-holes that communicate.

Secondary shower nozzle 4 by the auxiliary jet 21 that tightly is with swivel nut 22 be threaded with the auxiliary jet seat 23 of band sealing ring 24 be integral form, the height of auxiliary jet 21 is greater than main burner 20.

Be fixed with the burnt gas switch 1 of bringing tracheae 3 on kitchen range 2 lateral walls, relatively on the back-up block of the kitchen range inwall of burnt gas switch 1 and end face, by overlap 9 and briquetting 8 be screwed gauge tap 16, air inlet pipe 3, secondary shower nozzle 4, main jet head 5 respectively with joint 25, auxiliary jet seat 23, main burner seat 19 usefulness screw threads are fixed in the screw of nozzle boss 6 upper surfaces and a side, and the three communicates by air flue, have sealing ring and be thin and

thick rubber ring

13,14 cover plate 12, one end of pull bar 11 and the screw rod end of spool 15 pass thin, thick rubber ring, cover plate, through hole screw on the pull bar, nut is fixed on the lower surface of cover plate 12, nozzle boss 6 usefulness two screws that assemble are fixed on base plate 7 centre positions of kitchen range 2 band through holes, as Fig. 1, shown in Figure 2.

During use, cooker is placed on the gas-cooker, open burnt gas switch 1 igniting, combustion gas is in air inlet pipe 3 enters major and

minor shower nozzle

5,4 respectively, at this moment cooker is pressed on the briquetting 8, move down at gravity effect lower lock block, and drive depression bar 10, the pull bar 11 link together with it, gauge tap moves down together, drive spool 15 fixed thereon by pull bar 11 and also move down, disengaging contacts with main burner seat 19, forms air flue 18 betwixt, combustion gas enters main burner 20 for using, as shown in Figure 4 by air flue 18.

If cooker is taken away, briquetting 8 no pressure just set back, and while depression bar 10, pull bar 11 resets and drive spool 15 resets, then spool 15 withstands main burner seat 19, and combustion gas can't enter 20 fray-outs of flame of main burner, promptly closes automatically, as shown in Figure 3, reach purpose of energy saving.

Main burner 20 flame combustions or when extinguishing, there is flammule at the auxiliary jet place always, if just burnt gas switch 1 is turned off at last when stopping using kitchen range, at this moment the flammule at auxiliary jet 21 places also extinguishes and quits work.
