Description

A kind of pair of flame stove

Technical field

The utility model is a kind of pair of flame stove, and more precisely a kind of have gas-fired infrared sheet to produce heat radiation, and has external combustion flame to increase the stove and accessory mechanism of thermal source and the lifting thermal efficiency.

Background technology

Stove and accessory is mainly to provide thermal source with cooking food, and usings gas as the stove and accessory of heating energy source, is commonly referred to as gas oven.The mode of heating of gas oven, can be divided into direct heating type and the large class of indirect heating type two haply on the market, and wherein indirect heating type belongs to infrared gas stove.The principle of heating of infrared gas stove, main system utilizes gas combustion HEATING INFRARED line potsherd, is approaching when taking the photograph formula 900 and spending, and potsherd can be rubescent and be produced infrared radiation, then with infrared radiation heat food; Different from the gas oven principle of heating of general direct heating type, general gas oven is burning watt direct heat food, without intermediate energy switch process, therefore the fire of burner is larger, heating is faster.

Infrared gas stove system utilizes gas combustion HEATING INFRARED line potsherd, and its device is only applicable to family expenses gas oven compared with the occasion of low pressure, and its gas pressure is less than 1Kg/cm2; Once be applied to the gas pipeline of higher pressure, business with in the about 1Kg/cm2 of its pressure of fast stove left and right, have from fire (jump fire) phenomenon, this flame can float above infrared ceramic ceramics, both dangerously also can reduce efficiency of combustion; Therefore, how infrared ceramic ceramics is applied in to higher pressure occasion, both can possesses the benefit of infrared radiation heat food, can take again the efficiency of combustion of security and unlikely attenuating gas into account, the problem that need solve for the utility model.

Utility model content

The purpose of this utility model is to provide a kind of pair of flame stove, solves above-mentioned one or a plurality of of the prior art.

A kind of pair of flame stove of the utility model, comprising: burner, and burner comprises mixing tube, ring-like vaporizer and combustion chamber, and mixing tube one end connects the gaseous mixture of gas and air, and the other end connects ring-like vaporizer; Stepped ring-like furnace wall, is located between ring-like vaporizer and combustion chamber, and lower end, stepped ring-like furnace wall is provided with ring seat and through hole, via through hole setting, ring-like vaporizer is communicated with combustion chamber lower edge; Upper end, stepped ring-like furnace wall is provided with ring-type flame envelope ring, and its lower end is provided with the flame envelope hole that ring is arranged, and makes one end, flame envelope hole lead to ring-like vaporizer, and the other end leads to combustion chamber upper limb; Gas-fired infrared sheet, is provided with a plurality of fire holes, is placed in ring seat; Internal flame ring, has internal combustion chamber, is placed in the top of gas-fired infrared sheet.

A kind of pair of flame stove of the utility model, when the gaseous mixture of gas and air enters ring-like vaporizer from mixing tube, a part of gaseous mixture is after the fire hole burning of gas-fired infrared sheet, in internal combustion chamber, produce heat radiation, another part gaseous mixture sprays into combustion chamber upper limb burning from flame envelope hole, this have flame envelope ring and internal flame ring is combined to form the U-shaped combustion chamber in central heat build-up combustion chamber and outer ring, the residual flame producing when the flame impingement internal flame ring wall face of flame envelope hole ejection has the combustion aid function of igniting, and can increase thermal source and promote the thermal efficiency.

In some embodiments, flame envelope hole arranges towards central authorities the mode that is the lateral tilt of facing upward.

In some embodiments, burner is placed in the internal flame ring of gas-fired infrared sheet top, and its height need be lower than the flame envelope ring height of upper end, furnace wall.

The specific embodiment

As Figure 1-4, a kind of pair of flame stove of the utility model, comprising: burner 10, has mixing tube 11, ring-like vaporizer 12 and combustion chamber 14; Mixing tube 11 one end systems connect the gaseous mixture G of gas and air, and the other end connects ring-like vaporizer 12; Stepped ring-like furnace wall 13, is located between ring-like vaporizer 12 and combustion chamber 14, and 13 lower ends, stepped ring-like furnace wall are provided with ring seat 132 and through hole 131, via through hole 131, arranges ring-like vaporizer 12 is communicated with the lower edge of combustion chamber 14; 13 upper ends, stepped ring-like furnace wall are provided with ring-type flame envelope ring 133, and its lower end is provided with ring and arranges flame envelope hole 134, and makes 134 one end, flame envelope hole lead to ring-like vaporizer 12, and the other end leads to combustion chamber 14 upper limbs; Flame envelope hole 134, for arranging towards central authorities the mode that is the lateral tilt of facing upward, to form cyclone type flame envelope, makes burning more complete.

In addition, gas-fired infrared sheet 20, is provided with a plurality of fire holes 21, is placed in 13 ring seats of ring-like furnace wall.Internal flame ring 30, has internal combustion chamber 31, is placed in the top of gas-fired infrared sheet 20, makes the flame of fire hole 21 ejections of gas-fired infrared sheet 20 form internal flame; In this preferred embodiment, the height of internal flame ring 30 need, lower than flame envelope ring 133 height of 13 upper ends, ring-like furnace wall, can make flame envelope and internal flame produce mutual combustion-supporting effect like this.

Therefore, the gaseous mixture G of gas and air enters ring-like vaporizer 12 from mixing tube 11, a part of gaseous mixture G is after fire hole 21 burnings of gas-fired infrared sheet 20, in internal combustion chamber 31, produce thermal-radiating internal flame, another part gaseous mixture G sprays into combustion chamber 14 upper limb burnings and forms flame envelope from flame envelope hole 134, can increase thermal source and promote the thermal efficiency.

A kind of pair of flame stove of the utility model, has following revising of the functions:

1. by flame envelope ring 133 and internal flame ring 30, be combined to form the U-shaped combustion chamber 14 of internal combustion chamber 31 and outer ring of central heat build-up burning, the residual flame producing when flame impingement internal flame ring 30 wall of flame envelope hole 134 ejections has the combustion aid function of igniting.

2. flame envelope ring 133, higher than internal flame ring 30, uses gas-fired infrared sheet 20 hyperthermia radiations simultaneously, can make flame envelope and internal flame produce mutual combustion-supporting effect, and gas is fully burnt, and has advantages of the thermal efficiency of lifting.

3. flame envelope hole 134, for arranging towards central authorities the mode that is the lateral tilt of facing upward, to form cyclone type flame envelope, makes internal flame and flame envelope pair flames combustion-supporting more perfect.

The above is only a kind of embodiment of the present utility model; it should be pointed out that to those skilled in the art, do not departing under the prerequisite of the utility model creation design; can also make some similar distortion and improvement, within these also should be considered as protection domain of the present utility model.
