Abstract

The utility model relates to combined gas range with common and blowtorch type burner. The gas supply valve conducts the gas into the small flame gas conduit and intense flame gas conduit respectively. The double control gas supply valve controls the gas demand of the two gas conduit individually. The small flame loop burner is communicated with the small flame gas conduit which has an air door at the terminal. The intense flame barrel-shaped burner is arranged inside the ring of the loop burner. A nozzle is fixed at the inside bottom of the barrel-shaped burner, and the spraying port of the nozzle faces upwardly. The side wall of the barrel-shaped burner is provided with intake port, and the bottom end of the nozzle is communicated with the intense flame gas conduit. The utility model has the advantages that: the blowtorch type intense flame and the common small flame are convenient in usage; the gas and the air are completely mixed, the combustion temperature is high, the combustion is complete and the energy is saved; the flame produced by the sprayed gas in high speed mixing with the air can directly be sprayed to the bottom of the gas range, so that the heat efficiency is high; the combustion is complete, basically generating no smoke and oil, and no scale is formed at the bottom of the gas range, favoring to the environment; the structure is simple, the cost is low and the production is convenient and easy.

Description

Combined gas range

(1) technical field

The utility model relates to a kind of gas kitchen ranges, particularly a kind of combined gas range.

(2) technical background

The plain edition burner of existing gas kitchen ranges is introduced combustion gas respectively in the burner of big fire and little fire, mixes with air, derives burning from a plurality of apertures.Because of its shunting speed is lower, the fuel gas buring temperature is lower, and the thermal efficiency is lower, and therefore all compositions in the combustion gas all can not be burnt, and has wasted energy, and unburnt remaining combustion gas simultaneously pollutes the oil smoke of environment, also can form the black carbon deposit in the bottom of a pan.Though the kuppe or the cyclone cover of various designs are arranged, can not improve combustion position at all, improve the thermal efficiency.Chinese patent 99252726 " energy-saving gas cooker " adopts cylindrical nozzle to reduce basic fiery area, improves the thermal efficiency.But this kind gas kitchen ranges relies on cooker GRAVITY CONTROL ball valve, and is very easily flame-out when cooker is removed, and relies on stopping of cooker bottom to disperse combustion gas to make itself and air mixed combustion, and whether combustion gas can fully mix with air influenced by the cooker bottom shape.And this kind gas kitchen ranges do not had little fire screen, is not easy to large and small fire and regulates and use.

(3) utility model content

The purpose of this utility model is a kind of combined gas range with plain edition and blowtorch type burner of design, provides a kind of thermal efficiency high gas kitchen ranges easy to use.

The utility model comprises gas conduct pipe, burner, air door, steam supply valve.Gas Pipe and steam supply valve join, and steam supply valve imports little fiery gas conduct pipe and big fire gas conduct pipe respectively with combustion gas.Two control gas supply valves are controlled the air demand of two conduits respectively.Little fire is affixed with little fiery gas conduct pipe and be connected with annular burner, and little fiery gas conduct pipe end has air door.Big fire is arranged in the ring of annular burner with the tubular burner.Tubular burner inner bottom part fixed nozzle, nozzle spout are upwards.On the barrel of tubular burner side ventilating opening is arranged.The nozzle tail end is connected with the big fire gas conduct pipe.

The utility model has the advantages that: 1 has the big fire of blowtorch formula and common little fire, easy to use; The combustion gas of 2 big fire fully mixes with air, the ignition temperature height, and burning is complete, energy savings; 3 combustion gas that spray at a high speed and the mixed flame of air directly spray to cooker bottom, thermal efficiency height; 4 because of burning fully, do not have oil smoke substantially, also can not form dirt in the cooker bottom, the favorable environment protection; 5 is simple in structure, and cost is low, is convenient to promote produce.

Fig. 1 is the vertical section schematic diagram of the utility model combined gas range burner.

(5) specific embodiment

As shown in Figure 1, Gas Pipe 1 is joined with steam supply valve 2, and steam supply valve 2 imports small fire burner conduit 5 and big fire gas conduct pipe 4 respectively with combustion gas.Steam supply valve 2 is a double control valve, controls the air demand of two conduits 4,5 respectively.Little fire is affixed and be connected with annular burner 10 and little fiery gas conduct pipe 5, and little fiery gas conduct pipe 5 ends have air door 3.Big fire is arranged in the ring of annular burner 10 with tubular burner 8, and tubular burner 8 diameters are slightly less than the diameter of annular burner 10 endoporus, and the top is higher than annular burner 10 bottoms, is lower than annular burner 10 tops.8 inner bottom part fixed nozzles 6 of tubular burner, nozzle 6 spouts make progress, and spout and annular burner 10 distance from tops are 2～4 times of tubular burner 8 diameters.On the tubular burner 8 Lower Half side barrels ventilating opening 7 is arranged.Nozzle 6 tail ends are connected with big fire gas conduct pipe 4.

Steam supply valve 2 will have the combustion gas of certain pressure to send into big fire gas conduct pipe 4, the nozzle 6 at a high speed ejection of the combustion gas of certain pressure through the small-bore arranged, the lateral pressure of high velocity air descends, air is inhaled in the tubular burner tube 8 through tubular burner 8 sidewall ventilating openings 7, with combustion gas mixing, in the burning of top, 8 chambeies of cylinder, be the burner of blowtorch type.When 4 minimizings of big fire gas conduct pipe were sent in steam supply valve 2 adjustings, the combustion gas speed of nozzle 6 ejections reduced the also corresponding minimizing of inhaled air.Gas flow rate height because of from nozzle 6 ejections mixes fully with air, and burning is complete, and the higher boiling composition in the combustion gas also can burn, thereby makes full use of the combustion gas energy, and few residuum produces oil smoke hardly.The flame of tubular burner 8 concentrates on middle part, the bottom of a pan, and because of just taking fire in 8 chambeies of tubular burner, what contact with the cooker bottom is the heat zone of flame, has improved heat transfer efficiency.Steam supply valve 2 is regulated the air demand that infeeds big fire gas conduct pipe 4, promptly regulates blowtorch formula tubular burner 8 flame size.

Identical with the general gas kitchen range, steam supply valve 2 will have the combustion gas of certain pressure to send into little fiery gas conduct pipe 5, and air enters little fiery gas conduct pipe 5 through too small fiery gas conduct pipe 5 terminal air doors 3, and combustion gas mixes with air, burns at annular burner 10 fire holes.

Identical with the general gas kitchen range, when only needing little fire, steam supply valve 2 cuts out big fire gas conduct pipe 4, and only to little fiery gas conduct pipe 5 air feed, center tubular burner 8 promptly extinguishes, only surplus little fire.

Identical with the general gas kitchen range, on annular burner 10, install annular kuppe 9 additional, regulate gas-flow to and flow velocity, help little fire burns.
