Description

Burning-rate accelerator adding apparatus for gas stove

The utility model relates to the device that a kind of gas oven installs combustion adjuvant additional.

Just present commercially available gas oven, when burning, only utilize the air (containing oxygen) in the kitchen, if kitchen improper ventilation especially, then oxygen content is because of being burnt gradually, and content is less and less, even only reach in the air oxygen content about 16%, then gas can not be by completing combustion, and produce a large amount of CO and carbon (C).

CO is a toxic gas, the brain cell nerve is damaged, and the carbon ash is except that to the indoor pollution, and a large amount of the bottom of a pan ashes is more accumulated in the bottom of a pan, increases the puzzlement that the housewife cleans.

This novel purpose provides a kind of gas oven to install the device of combustion adjuvant (for example oxygen) additional at what.

This novel purity oxygen (99.8%) that utilizes is helped gas combustion, except can preventing CO and carbon, more can save the gas expense, because pure oxygen De System causes this, the per kilogram liquid oxygen can be controlled under the price at the bottom of the utmost point, but quantitatively broadcast out at indoor mat oxygen in addition, make air comparatively fresh, salubrious, can also be as the usefulness of first aid.To the what using method, can explain orally as following.

The simple declaration of drawing:

Figure 1 Department commonly uses the stravismus schematic diagram of gas oven switch.

Fig. 1 A Department commonly uses gas oven rotor schematic diagram.

Fig. 2 is for commonly using gas oven switch internal structural map.

The cutaway view that Fig. 2 A Department looks from the 2A-2A of Fig. 2 direction Mining.

This novel oblique view of figure 3 Department.

This novel cooperation air tank gas transmission schematic diagram of figure 4 Department.

This novel part cut-away view that cuts open of figure 5 Department.

As shown in Figure 1, traditional gas switch has a knob (30) except rotating gas flow, also closes a those shown that son (20) is Fig. 1 with a compressing or claims in the rotor spring valve of the female fiery gas flow of female fiery passage (214) control. Close (cover) hole (11) of inserting of son when closing the upper logical gas hole (211) of son by the containing of gas switch seat (10), when extremely relative with gas pipe phase seam (12) from sealed state rotation, gas can flow to 3 directions through the gas inlet (211) of closing son by port (or claiming interface), one reaches igniting action for flowing to female fiery opening (214), two are the past beneath opening that communicates (213), pass straight through to that to close son outer and (ask the three bb profile of readding figure two with the gas port of the gas seat that closes sub-close proximity, i.e. 113 among the figure two), from then on a port (113) flows to the nozzle (115) of gas again, also has one to flow to another port (21) that flows to that is into wide-angle and disengage gas through a nozzle passage (112) toward jet hole (114) again.

Further explain the profile (figure two) of bb, (22) Department refer to close son outside gas switch, as the sleeve pipe of knob. (211) close the upper circular hole that communicates of son with (213) Department, when the gas blow vent (12) that closes the upper blow vent (211) of son and gas seat to timing, then the flow of gas is maximum at this moment. Again when gas from close sub-blow vent (211) flow to female fire required close sub-blow vent (214) after, flow into again the blow vent (111) of gas switch seat, and from then on mouthful outwards ejection of past opening (105), simultaneously after knob start to a direction, has an ignition device that links to each other with the gas switch seat by what, because spring rum point flint produces high tension spark, light gas.

Again when knob (30) will close son (20) and go to another port (212) that closes son, the inlet (12) that joins by what gas switch seat and gas pipe, be designed to when closing sub-blow vent (211) and be rotated soon to sealing place, then another blow vent (212) just is connected, gas still can disengage smoothly, and can cutoff.But after (211) were transferred to sealing place entirely, during the port of only remaining (212), then gas only flowed to the blow vent of (21), was sprayed by nozzle (114) through pipe (112) back again.Then burning place of gas oven is just fiery in the middle of remaining be commonly called as so-called, and its firepower is decided on gas pressure because of the blow vent very little about 0.45 to 0.7m/m(of (212)), so firepower is less.In the middle of being centered around around the fire it (greatly) fire then be closed by what (211) port, can't lead to gas to (213) and and then deliver to (113) and spray from (115), so burn-out more than is the rough situation of traditional gas combustion.

Fig. 1 and Fig. 2 indicate the rotary switch that they (40) Department refers to air intlet amount (that is an oxygen) the control number of gas oven in addition.

Utilize when closing son and being rotated to the method ， Department of what innovation, can spray simultaneously by the start purity oxygen,, reach the purpose of completing combustion to cooperate synchronousing combustion with gas.

Certainly at first will add as shown in Figure 4 an air tank (50), purity can be up to 99.8%.

Please three read Fig. 3, the insertion oral area part that to close son now prolongs, so that install the hole of two logical oxygen additional, simultaneously outside the gas switch seat mash gas siphunculus seat (10), in addition add an oxygen siphunculus connecting base (60) again and Yang Qi Department locates input by (63), hold the path of oxygen with cooperation.When the gas port is reversed to (211), parallel with (211) blow vent and establish an oxygen ventilation mouth (222) in addition closing sub-front end, oxygen and gas are disengaged simultaneously.But in order to prevent that oxygen and gas are in nozzle, because of pressure differential, might mix the back to reflux and be commonly called as the anxiety of " tempering ", so other end outlet (224) that this oxygen ventilation mouth (222) is straight-through with closing son, must be connected with a hollow conduit, communicate to separate with gas passage hole (21).

The close sub-front end parallel with (212) has an oxygen port in addition when gas closes son and goes to the less passage of flow (212) again, that is oxygen is from the blow vent (221) of another less (about 0.1m/m), catch up with and state oxygen ventilation hole (222) equally, also be to be connected with hollow conduit, oxygen is not communicated with gas path (21), and directly pass to straight-through other end blow vent (223), synchronous with gas blow vent (212), oxygen is sent, help gas combustion, to reach completing combustion person.

The external diameter of EC is wanted one of little what gas siphunculus (road) i.e. (21) to what (221) to (223) and (222) to (224), with the circulation of antifouling gas.

Further explain the tow sides of the gas of Fig. 3 and Fig. 4 and oxygen switch Zuo ， Department front view and rearview.(615) (715) and (815) respectively are the port of oxygen.Again from the AA profile of Fig. 5, outside the no longer superfluous Yan of mash gas path, sub-button commentaries on classics accommodates two oxygen ports (221 and 222) simultaneously at (211) Shi Zeneng oxygen intake (63) is being closed in the oxygen ventilation hole, also the while button produces the passage of (222), make oxygen from closing the sub-other end (224), pass to two places through oxygen channel (226), one place's blow vent sprays via (615), to match with gas nozzle (115), another place then passes through via passage (810), spray through oxygen jet (815) again, match with gas nozzle with (114), this moment, another gas blow vent (212) and oxygen ventilation mouth (221) then were closed, or the trace ventilation.

Again after (211) and (222) are sealed entirely, and change gas port (212) and oxygen port (221) into when spraying gas synchronously, then the gas siphunculus of (212) is only by (114) ejection gas, (115) gas then closes, then enter to what oxygen aspect by (221) port, spray toward nozzle (715) by back Jing via passage (710) again, cooperate burning with gas with (114).

In a word, above-mentioned gas or oxygen ventilation mouth are respectively to have three, and then the gas blow vent is respectively large outlet (115) and little outlet (114) and female fire outlet (105).And oxygen outlet has a middle outlet (615) and little outlet (815) and littler outlet three outlets such as (715).

Last point, gas nozzle (115) are to mix under the what atmospheric pressure after the spontaneous combustion burner sprays respectively with oxygen jet (615), and combustion-supporting burning is so can thoroughly prevent the danger of " tempering ".And the gas nozzle (114) in the gas oven central ring and oxygen jet (715) and (815) are directed at burner with it and just mix outward also as (115) and (615).

Above-mentioned in addition air tank can utilize the mode of threeway, in two openings, select one of them to install a tool timer, control oxygen is after unlatching, it can be closed voluntarily in several minutes, the oxygen of sending is for the fresh usefulness of room air, has a breath of fresh air the need when for example AEROBIC DANCE or work move for indoor live in person.Also have another opening to take over snap joint, be connected on the Gas cooker, need utilize oxygen to work as the first aid time spent if having, this snap joint can be unpluged, another is with the snap joint of oxygen mask, the usefulness of carrying out first aid on the reconfiguration.
