Abstract

The utility model relates to a pressure increasing oxygen enriching impact combustion energy saving gas range, belonging to the gas range of the class of the civil use. Through altering the structure of the fire head and the input air of the air door, the pressure increasing oxygen enriching impact combustion energy saving gas range overcomes the defects of ' small fire power, no pan speeding, flame and heat abstraction escaping ' of the original gas range. The utility model is characterized in that 1) the fire head is inwards concave curved face, and eyelets are centripetally distributed on an inner and an outer rings. 2) The air acting as the outer force source (such as blower, etc.) generates the (air pressure is larger than 100 Pa, and the air flow is larger than or equals to 10 cubic meter per hour) strong wind which is delivered in the air door. The functions of both lie in that the flame and the heat quantity generated by firing are only formed the impact contact for the effective heating scope (the diameter of the circle is 20 cm) on the center of the bottom of the pan.

Description

The supercharging oxygen enrichment impacts the combustion energy saving gas-cooker

The supercharging oxygen enrichment impacts the combustion energy saving gas-cooker, belongs to civilian class gas-cooker.

Selling on the market at present and all civilian class gas-cookers (figure one) that using, all are aperture (Φ≤0.8) ejection fuel gas by burnt gas switch, form the automatic suck air of negative pressure at the air door place, the two mixing formation " mist " (pressure＜5Pa), and from Internal and external cycle eyelet (the outer ring eyelet is centrifugal and outwards disperses) ejection on the height of anger, make the flame of burning generation and the transmission of heat, be the centrifugal ease state that floats of dispersing in the bottom of a pan, and the best of often floating center, the effusion the bottom of a pan is subjected to heat rating (diameter is the circle of 20cm), until the effusion the bottom of a pan with handle, handle burns and scalds, burn out, form unnecessary waste.Because can't be only being subjected to heat rating to form impact to the best at center, the bottom of a pan, the flame that generates and heat contact, so all there is the deadly defect of " waste is big, efficient is low, firepower is little, do not urge pot " from all at present gas-cookers of combustion mechanism.

The purpose of this utility model is the civil class gas-cooker that a kind of " firepower greatly, heat transfer is fast, efficient is high " will be provided.

The purpose of this utility model is achieved like this: the first, change the planform of former duration and degree of heating, and make duration and degree of heating become inner sunken face, its eyelet becomes 20 ° of-80 ° of angles entad and with horizontal line; Second, a micro-blower is installed in the general structure of stove, and be connected with the air door of gas-cooker by sebific duct, when fuel gas sprays through switch, with fermented soya beans, salted or other wise wind through sebific duct by force drum advance the high wind (blast 〉=100Pa of gas-cooker inlet channel, air quantity 〉=10 cubic metre/hour) mix after, and in passage, form pressure＞10Pa, the mist of air quantity 〉=10 cubic metre/hour, under novel duration and degree of heating and acting in conjunction greater than 10Pa pressure, mist is from duration and degree of heating eyelet (by its angle) ejection, and burning entad generates and become with horizontal line the blue flame that has impact and the heat of 20 ° of-80 ° of angles.Self the bottom of a pan is not had impact because flame on the eyelet of duration and degree of heating outer ring and heat are single, but also flame and the dispersing on a small quantity of heat that duration and degree of heating inner ring eyelet generates formed blocking and blocking of impact; Simultaneously, because the air quantity big (its essence is that oxygen content is big) that advances of drum by force, finally make that burning is more fierce, more thorough.According to my several test, efficient 〉=12.83% that the utility model gas-cooker is improved (test data of seeing below).

The utility model is owing to only need improve duration and degree of heating and the angle of eyelet and load onto a small blast fan (position that it is put or installs will be fixing by the user or the producer) and in addition and save sebific duct, so structure is very simple; Simultaneously because the starting point does not lie in the structure that changes air door and the air inflow and the control structure thereof of fuel gas, thus it to air door and air inlet switch and mode of operation thereof without any special requirement; In addition since duration and degree of heating and air blast (or ventilating fan) be and can spread the independently member that changes, so after the generation that has a power failure, only need load onto the use that just can burn away of former duration and degree of heating; At last, because by force in the air quantity that strengthens, be rich in the oxygen molecule (air mass flow of the automatic inspiration of negative pressure＜0.5 cubic metre/hour, air blast is air mass flow 〉=10 advanced of drum cubic metre/hour by force), make burning more fierce, more abundant, more thorough, thereby tool and very strong green effect and environment-friendly advantage.

Concrete structure of the present utility model is provided by accompanying drawing two.

Figure two is the profiles that impact the combustion energy saving gas-cooker according to the supercharging oxygen enrichment that the utility model proposes.

Below in conjunction with concrete structure and the combustor of figure two detailed descriptions according to the gas-cooker that the utility model proposes

Reason.

The utility model gas-cooker by novel duration and degree of heating (6), burnt gas switch (2), air door (7), inlet channel (3), air blast (because drawing little, can't draw in the drawings) and the effect pipe (8) that is attached thereto thereof and always framework members such as (not drawing in the drawings) form.

The utility model combustion gas in use, at first be that fuel gas (1) sprays in the inlet channel (3) through burnt gas switch (2) aperture, after high wind (4) that air blast bloats mixes, form pressure 〉=10Pa, air quantity 〉=10 cubic metre/hour mist (5) in inlet channel (3) lining, and under the acting in conjunction of the pressure of duration and degree of heating (6) wind concave curved surface eyelet and angle and mist (5), make blue flame that mist (5) spray body and burning generate and heat only be subjected to heat rating to form impact and contact the best of center, the bottom of a pan (9).

For the most effective explanation and make the advantage that it is believed that the utility model gas-cooker, I spy has done following contrast test, the data of its contrast following (fuel gas source is a natural gas, air pressure＜2000Pa, INO Intake Open closes aperture Φ＜0.8, blower power=40W):

According to above-mentioned data, we can get following several simple correction data:

1) as pot body diameter D=220, the heavy G=4.1kg of water needs 13 minutes and 15 seconds with the boiled old burning of water, new kitchen range needs 11 minutes and 33 seconds, new kitchen range consumes less: 1 minute 42 seconds, calling by name was exactly: new kitchen range institute power consumption source and time is 87.17% for old kitchen range institute power consumption source and between being only, raises the efficiency 12.83%.

2) as pot body diameter D=290, the heavy G=4.1kg of water needs 12 minutes and 33 seconds with the boiled old kitchen range of water, and new kitchen range needs 10 minutes and 38 seconds, and new kitchen range consumes less: 1 minute 55 seconds, that is: the consumption of new kitchen range only be 84.73% of old kitchen range consumption, and raises the efficiency 15.27%.

In above-mentioned test because new duration and degree of heating be manual manufacturing, the angle of its outer ring eyelet＞80 °, the poor efficiency utilization of air blast air quantity, the effective impact to the bottom of a pan reduces with the intensity that contacts with heat to make flame, thereby the numerical value of raising the efficiency is unsatisfactory, and the efficiency value that in fact can improve is definitely greater than 12.83% in other words.
