Abstract

The utility model relates to a gas range, which is composed of a range body, gas supply pipes, fire rings, and valves, wherein the fire rings are annular inner and outer rings which are connected with the gas supply pipes of the inner and the outer rings respectively, and a valve is installed on the pipeline of each of the gas supply pipe. The gas range has the advantages of stronger firepower due to the inner and outer rings, multistep regulation and convenient operation due to the respective control of the inner and outer rings by separate valve, reasonable structure, reliable performance, low cost, and wide usages due to relatively reasonable structure of valves.

Description

Gas kitchen ranges

The utility model relates to a kind of gas kitchen ranges, is or rather to belong to this technical field of kitchen range of utilizing natural gas or liquefied petroleum gas or gas-fired by a kind of gas kitchen ranges with two pyrosphere structures.

Now the kitchen range that generally use all are to adopt an induction tunnel that air-flow is burnt in gas tank or natural gas pipe are incorporated into pyrosphere the gas kitchen ranges, this burning kitchen range are unfavorable for utensil is evenly heated owing to the flame circle is concentrated, the efficiency of heating surface is lower, has limited the use of Gas appliance widely; Moreover the valve of this kitchen range mostly adopts needle valve structure, and its processing is complicated, and is worn easily when long-term the use and influences the use of kitchen range.

No. 90205067 Chinese patent discloses a kind of double-firerings swirl flame burner, this burner by burner body and in, outer waveguide rotary ring and ring cowling are formed, have one or two air inlet pipe with in, external ring cavity communicates, at the center of annular chamber circular secondary intake opening is arranged, interior, the arc secondary intake opening is arranged between the external ring cavity, inside front at each annular chamber has breach, rotary guide ring and ring cowling can be installed, this burner has mainly solved this problem of flame uniformity, the burning area of this burner is big, sufficient combustion, it can be assembled into kitchen range with other accessory of kitchen range, make its complex structure but the leading of this burner revolved structure, manufacture difficulty is big, and is difficult to flame size in two pyrospheres is done control and regulation on a large scale.

Chinese patent 91228593 discloses a kind of three ring fire gas furnaces, and the combustion chamber in the stove and accessory is changed into three rings, its structure more complicated, the cost height, also show inconvenience in the use, be difficult to promote the use of, light the pipe aspects at valve and naked light in addition and do not make corresponding correction.

Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art and a kind of two pyrosphere structures that have is provided, combustion flame is evenly distributed, and can do to regulate significantly to flame size, and is simple in structure, cheap, safe and reliable gas kitchen ranges easily.

The purpose of this utility model realizes in the following manner:

A kind of gas kitchen ranges is by kitchen range body, gaspipe, be installed in the pyrosphere on the body, the tolerance by-pass valve control is formed, and wherein pyrosphere is the inside and outside pyrosphere of annular, inside and outside pyrosphere is connected with separately gaspipe respectively, is equipped with the tolerance by-pass valve control on the pipeline of every gaspipe.

Gas kitchen ranges of the present utility model is because outer burning ring in adopting makes that its firepower is stronger; And because interior outer burning ring is controlled by valve separately respectively, can carry out multistage adjusting to kitchen range, easy to use; Adopt reasonably valve mechanism in addition, rational in infrastructure, dependable performance, overall structure is simple and clear, and cost is low, and is of many uses.

Below in conjunction with accompanying drawing structure of the present utility model and technology contents thereof are advanced an explanation that relates to:

Fig. 1 is the integral installation distribution structure schematic diagram of gas kitchen ranges of the present utility model;

Fig. 2 is the schematic top plan view of gas kitchen ranges of the present utility model;

Fig. 3 is the section structure cross-sectional schematic of interior pyrosphere or outer burning ring;

Fig. 4 is the cross-sectional schematic of the valve that adopted in the utility model.

Referring to whole accompanying drawings, particularly Fig. 1,2, gas kitchen ranges of the present utility model, by kitchen range body 1, gaspipe 2 is installed in the pyrosphere 3 on the body 1, tolerance by-pass valve control 4 is formed, and wherein pyrosphere 3 is the inside and

outside pyrosphere

31,32 of annular, interior outer burning

ring

31,32 is connected with separately gaspipe 21,22 respectively, be equipped with tolerance by-pass valve control 41,42 on the pipeline of every gaspipe 21,22, what of each road air feed each valve can control, and then the size that is used for regulating flame.

Above-mentioned said body 1 mainly is meant the existing structure relevant with kitchen range, as Holder for cooking utensils 11, kitchen range support 12, relevant spare and accessory parts with kitchen range of connector and installation and figure go up unshowned igniter or sparking gear (piezoelectric ceramic ignitor) etc., these structures are the mature structure or the known accessory of prior art, do not elaborate at this;

A naked light air supply pipe 23 is housed on the kitchen range body 1, the combustion head 33 of naked light air supply pipe 23 is positioned at inside and outside pyrosphere 31, between 32, be equipped with valve 43 on the naked light supply air line 23, because the main effect of naked light combustion head is in lighting, fire on the outer burning ring, it is an ever-burning flame, except settle should be between interior outer burning ring, on the naked light supply air line, a decompressor should be installed, in Fig. 4, described decompressor is a column that charges into the pipeline bending part, for example rivet 5, can make the pressure of this passage reduce tens of times like this, reduce the waste of combustion gas.

Referring to Fig. 3, above-mentioned interior pyrosphere 31 or the air-flow spray orifice on the outer burning ring 32 are inside and outside two row's apertures 34,35, the axial line of spray orifice 34,35 and the angle of plumb line, scope be 20～60 the degree, adopt this angle, can make burned flame to the cooker homogeneous heating, improve the thermal efficiency, fuel saving, Fig. 3 are A-A among Fig. 2 or the cutaway view of A '-A ';

Above mentioned three valves can adopt identical structure, referring to Fig. 4, in the utility model, valve 4 is by valve body 44, handwheel 45, spool 46, valve rod 47, spring 48 is formed, 48 tops of spring are positioned on the spool 46 in the valve body 44, and valve rod 47 contacts with an end of spool 46, and valve rod 47 moves in valve body 44 through handwheel 45, the other end of spool 46 acts on the flow channels in valve body 44, tighten handwheel 45, inwardly promote spool 46 compression springs 48 by valve rod 47, the other end of spool props up flow channels, close gas circuit, otherwise, unscrew handwheel 45, under the effect of spring 48, spool 46 outer bullets are opened gas circuit; For preventing possible leakage, on spool, make several annular grooves, embedded seal ring 49; Two even three valves are installed together or valve body are made one, have laid two or three valves on a valve body among the figure.
