Description

Adjustable infrared stove with concave radiation plate

The utility model relates to a kind of infrared ray stove of gaseous fuel.

I have adopted the inner sleeve that slides before and after the energy to be communicated with the size of small combustion chamber with the control burning area on portion's structure within it at the red as fire outside line kitchen range of adjustable power (application number is 87210139) of first to file, thereby have realized the strong and weak fire control system of infrared ray stove.But in use find the radiant panel of present plate infrared ray stove, the radiant heat that the middle part is subjected to when using the spill the bottom of a pan differs very greatly different with comparing on every side, because it is inhomogeneous to be heated, makes result of use very poor.

The purpose of this utility model is a kind of the bottom of a pan thermally equivalent that makes of design, and combustion gas is fully burnt, and can keep the strong and weak red as fire outside line kitchen range of a kind of new type of adjustable of central heating.

The utility model takes following mode to realize, at first with my radiant panel (being ceramic wafer) in the red as fire outside line kitchen range of adjustable power of first to file, makes the concave face plate of various curvature as required.Former small combustion chamber changed into inside be set have twin-channel toroidal combustion chamber, wherein in the ring passage be air chamber, outer ring channel is the combustion chamber.Toroidal combustion chamber is in the below of radiant panel.In addition, changing straight-cylindrical little mixing tube in the injector into inner chamber is hyperbola or taper, to increase the flow velocity of combustion gas, combustion gas can be mixed fully with air.The shelves pyrosphere of adjustable support has been installed in the upper end of stove, can have been controlled the distance of the bottom of a pan and radiant panel arbitrarily, and save the energy effectively.

Further set forth structure of the present utility model below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is radiant panel shape figure of the present utility model;

Fig. 3 is the utility model binary channels toroidal combustion chamber floor map;

Fig. 4 is that the little mixing tube of the utility model cuts open schematic diagram;

Fig. 5 is the utility model shelves pyrosphere positioner figure.

The utility model is the radiant panel (5) that has porous in stove (8) upper end (Fig. 1), and the appearance of this radiant panel (see figure 2) is dish-like (A) or curved surface dish (B) or concave curved surface type (C).Distance is more even between this appearance and each position, the spill the bottom of a pan, especially when using weak fire, can obtain effect preferably.The garden circumferential edges of this radiant panel and stove driving fit mutually.Be that bottom in the stove is large-scale combustion chamber (1) in the bottom of radiant panel.At the middle part of large-scale combustion chamber is small combustion chamber, i.e. binary channels toroidal combustion chamber among Fig. 1 (2,3), wherein in ring passage (3) be air chamber, outer ring channel (2) is a fuel chamber.Both sides (see figure 3) at interior ring passage (3) is equipped with two ventilation ducts (4) at least, and the top of ventilation duct communicates with interior ring passage (3) air chamber, and the bottom links to each other with stove (8) bottom shell, and bottom end opening communicates with the stove outer air.The upper end of interior ring passage (3) air chamber has the slit, forms ring-type air feed band.Outer ring channel (2) fuel chamber top has the slit with interior ring passage (3) same area, and the bottom of its front end is connected with combustion gas entering opening (15).The rear end of combustion gas entering opening has the running-on that socket-connects with the inner sleeve (10) that can do the front and back slip.Chock flap (16) is equipped with in the inboard of advancing the borehole jack mouth in combustion gas, and chock flap is the garden plate-like and has a plurality of air admission holes.

In injector (11), be equipped with can before and after sliding inner sleeve pipe (10), the outer wall of inner sleeve is the garden tubular, the front end inner chamber of pipe is a bell mouth shape, the air inlet that the rear end is made up of 2 dowels at least.The slip of inner sleeve is that preceding the postponing of pull bar (14) that is mounted on nozzle (13) side drawn realization.Be with the anemostat (7) of a bell mouth shape in the front end outer of inner sleeve, inner sleeve and anemostat all are in the below of toroidal combustion chamber (2,3).Nozzle (13) is equipped with in the outside, rear end at injector (11), little mixing tube (12) (see figure 4) that outer wall is the garden tubular is equipped with in the inboard, its inner chamber is hyperbola (d) or two garden taper hole shapes (p), and the rear end of little mixing tube has at least one air admission hole, and little mixing tube is sleeved on the nozzle.

Be equipped with adjustable support (6) (see figure 5) of band shelves pyrosphere in the outside of stove (8), around stove, have three fulcrum posts (9) supporting adjustable support at least, on support, have multistage positioning hole (17).

Embodiment of the present utility model is as follows:

When using strong fire, pull back pull bar (14), the inner sleeve in the injector (11) slides backward thereupon, and little mixing tube (12) is inserted in wherein.Open nozzle (13) combustion gas by little mixing tube (12) with together enter inner sleeve (10) after air mixes and fully mix again, enter large-scale combustion chamber (1) by anemostat (7), partially mixed combustion gas enters the fuel chamber (2) in the toroidal combustion chamber by combustion gas entering opening (15), chock flap (16), and this moment is by concave surface radiant panel (5) ejection ignition combustion.When combustion gas is lighted, combustion-supporting by ventilation duct (4) to big small combustion chamber supplemental oxygen by the air chamber (3) of annular combustion chamber.Adjustable support (6) with heat build-up function is adjusted distance between the bottom of a pan and radiant panel (5) by the fulcrum post (9) on positioning hole on it (17) and the stove (8), reaches best user mode.

During weak fire, pushing drawing rod to stove (8) in makes inner sleeve in the injector (11) thereupon to front slide, makes in its running-on that slips into the combustion gas entering opening (15) below the toroidal combustion chamber (2,3).Open nozzle (13), after together entering the abundant once more mixing of inner sleeve (10) after combustion gas mixes with air by little mixing tube (12), enter the fuel chamber (2) of toroidal combustion chamber and by its slit ejection, by radiant panel (5) ignition combustion by porous chock flap (16) with the toroidal combustion chamber of inner sleeve (10) socket combustion gas entering opening (15) import department.This moment does not work in the large-scale combustion chamber.

The utility model has the advantages that:

1. can regulate the strong and weak fiery use state of infrared ray stove.

2. owing to adopted the spill radiant panel that heat energy is evenly distributed to the bottom of a pan.

3. the toroidal combustion chamber of Cai Yonging can not only be at weak when fire flame stabilization, and can both obtain sufficient oxygen supply with under the fiery two states of power.

4. little mixing tube has adopted the inner chamber of hyperbolic wire that the combustible gas flow velocity is increased, and it is more even that it is mixed with air.Especially when weak fire, make flameholding.

5. adopted to have the heat build-up function and adjustable support that can adjust desired height, can make the bottom of a pan and radiant panel remain optimum distance, saved the energy effectively.
