Abstract
The utility model relates to a double-pipe three-ring fire gas stove used in the family for cooking, comprising a stove body (1), a stove head (2), a burner (3), a control valve assembly (4) and an ejector pipe (5), wherein, the stove head (2) is provided with an outer annular gas chamber (6), a middle annular gas chamber (7) and a central gas chamber (8), the burner (3) and the upper part of each gas chamber form the tooth space of an ejector hole, the central gas chamber (8) is communicated with the middle annular gas chamber (7), and the middle annular gas chamber (7) and the outer annular gas chamber (6) are respectively connected with the gas outlet of the respective control valve assembly (4) through the corresponding ejector pipe and a nozzle. The utility model has the advantages of low cost, big fire power, perfect combustion, no yellow fire and black smoke appearing, etc.
Description
The utility model relates to a kind of gas furnace, especially a kind of household cooking gas furnace with three ring fires.
Household cooking gas furnace of the prior art belongs to atmospheric combustion formula gas furnace class.The burner diameter of this stove generally is no more than 12CM, and majority has only two air chambers, and firepower is not strong during burning.Chinese patent 91228593 discloses a kind of name and has been called: " three ring fire gas furnaces " technology, the burner of this gas furnace has outer shroud air chamber, middle ring air chamber and central air chamber.Three air chambers are connected with it by each self-corresponding induction tunnel respectively.The burner diameter of this stove is big slightly, has three ring fire flames during burning, and firepower is strong, and every ring fire can be regulated large, medium and small scope, and is easy to use, but shortcoming is to dispose three induction tunnels and the four-way adjusting interstage valve that cost is higher, cost is higher, a little less than the market competitiveness.
The purpose of this utility model be in order to overcome the deficiencies in the prior art, a kind of simple in structure, cost is low and firepower strong, burning is perfect three ring fire gas furnaces are provided.
The purpose of this utility model is achieved in that a kind of two-tube three ring fire gas furnaces, comprises body of heater, burner, burner, by-pass valve control assembly and induction tunnel; Wherein burner has outer shroud air chamber, middle ring air chamber and central air chamber, burner and each air chamber upper end constitute the teeth groove of gas jet orifice, it is characterized in that central air chamber communicates with middle ring air chamber, middle ring air chamber and outer shroud air chamber are connected with the gas outlet of separately by-pass valve control assembly by each self-corresponding induction tunnel and nozzle.
In order there to be enough air to support combustion gas completing combustion, the air door diameter of induction tunnel can be increased to 4.5-5.0CM, and the width of the annular air supply groove that the crack forms between outer shroud air chamber and the central air chamber is 1.2-1.4CM.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a plan structure schematic diagram of the present utility model.
Fig. 3 is the upward view of burner in the utility model.
Operation principle of the present utility model is: combustion gas enters by-pass valve control assembly (4) from air inlet pipe, it is threeway interlock control valve, after pushing its knob igniting, pass through the adjusting knob Position Control to air chamber air feed and gas flow thereof, have the gas-flow of certain pressure this moment and spurt into induction tunnel (5) from air door (9) through nozzle, suck air in certain amount and mixing, and entering outer shroud air chamber (6) and middle ring air chamber (7), the sub-fraction of the combustion gas of ring air chamber (7) then enters central air chamber (8) through passage in entering.Enter the gas jet orifice ejection burning of the combustion gas of each air chamber from burner (3).Air below the furnace bottom constantly flows to burner (3) on every side through annular air supply groove (10), makes fuel gas buring perfect.The power of combusting firepower can be passed through adjusting control valve door assembly (4), realizes with the air demand of controlling each air chamber.When knob in different angles, outer ring fire, middle ring fire are in corresponding break-make position together with the blast tube of center ring fire, thereby realize independent control.When big fire and moderate heat, the air feed burning simultaneously of outer shroud air chamber (6), middle ring air chamber (7) and central air chamber (8), when little fire or low baking temperature, middle ring air chamber (7) burns together with central air chamber (8) air feed.
The utility model compared with prior art has the following advantages:
1, cost is light. In ring air chamber and central air chamber share an induction tunnel air feed, its combustion efficiency and with two Air feed is basic identical respectively for the bar induction tunnel. Simultaneously, the by-pass valve control assembly replaces price with threeway interlock control valve Expensive four-way interlock control valve, thereby the cost of reduction product.
2, firepower burns perfect by force. Burner diameter of the present utility model can reach 14.0-14.5CM, combustion front Long-pending big. During big fire, firepower can reach more than the 4500KCaI/h. Because having increased induction tunnel air door diameter and air mends Give the width of groove, have enough air to support combustion gas fully to burn, be not prone to yellow fire and black smoke, the content of its CO Detection meets national standard.
Claims (3)
1, a kind of two-tube three ring fire gas furnaces comprise body of heater (1), burner (2), burner control (3), by-pass valve control assembly (4) and induction tunnel (5); Burner (2) has outer shroud air chamber (6), middle ring air chamber (7) and central air chamber (8), burner (3) and each air chamber upper end constitute the teeth groove of spray orifice, it is characterized in that central air chamber (8) communicates with middle ring air chamber (7), middle ring air chamber (7) and outer shroud air chamber (6) are connected with the gas outlet of separately by-pass valve control assembly (4) by each self-corresponding induction tunnel (5) and nozzle.
2, two-tube three ring fire gas furnaces according to claim 1 is characterized in that air door (9) diameter of induction tunnel (5) is 4.0-5.0CM.
3, two-tube three ring fire gas furnaces according to claim 1 is characterized in that the width of the formed annular air supply in space groove (10) between outer shroud air chamber (6) and the middle ring air chamber (7) is 1.2-1.4CM.
