The specific embodiment
Below, with reference to accompanying drawing, embodiments of the invention are described.
With reference to Fig. 1,1 is stove body, on stove body 1, disposes burner 3 with the burner offered on the panel 2 above covering it with the mode of opening 2a.On panel 2, put the masking material 4 of ring-type in the mode of the opening edge portion that covers burner opening 2a, in addition, also put by the outside at the masking material 4 of ring-type be seated at the pole shape material system on the panel 2 ring-type range frame 5a and be fixed on range 5 that a plurality of range pawl 5b on the range frame 5a constitute.
Burner 3 is by constituting towards the internal flame formula burner of a plurality of glory holes 31 of opening in being formed with on inner circumference portion.And, at the central portion of the inner space of burner 3, be provided with the cooking bottom temperature sensor 6 of the bottom surface that is connected to the cooking container P that puts on range 5, can detect the temperature of cooking container P by this sensor 6.In addition, cooking bottom temperature sensor 6 is relied on the top and is installed in the upper end of long support column 6a of above-below direction by spring (not shown).
Then, with reference to Fig. 2, describe the formation of burner 3 in detail.Burner 3 is to constitute by the burner body 33 of the ring-type that forms with mixing tube portion 32 and the burner head 34 that puts the ring-type on burner body 33.Burner head 34 has: the upper end between inside and outside two circumferential wall part 341,342 of inner peripheral wall portion 341, outer circle wall portion 342 and shutoff and compare the upper wall portions 343 that is projected into the outside with outer circle wall portion 342.Upper wall portions 343 forms in the mode of its external diameter less times greater than the internal diameter of masking material 4.And, make the upper surface of upper wall portions 343 be tilted to the below toward the outer side, flow down along the masking material 4 of ring-type so that fall soup juice that boiling on the upper wall portions 343 overflow.
On as internal perisporium portion 341 burner 3 inner circumference portion, burner head 34, and on circumferencial direction, exist the compartment of terrain to be formed with to be the glory hole 31 of long incision-like towards opening and on above-below direction in a plurality of.In addition, in order to prevent because of the bad generation of the not enough caused burning of auxiliary air, with at interval 2 mode and make glory hole 31 also be formed with little glory hole 31 '.
Each glory hole 31 favours circumferencial direction one side (clockwise direction among Fig. 2) towards the radially inner side of burner 3 and with the corner α (for example 45 °) that stipulates.Thus, because of can applying the composition that rotatablely moves, thereby can suppress flame extension to the inside to the flame that burning generated of the ejection combustion gas of coming out by glory hole 31 towards circumferencial direction.That is, flame is not easy to extend to the inboard of the circle mutually concentric with the ring center of the burner 3 of the combustion gas ejection axis institute adjacency of drawing from glory hole 31 (below, note is made the inscribed circle of combustion gas ejection axis).
In addition, as shown in Figure 3, even each glory hole 31 also is angle of inclination beta (for example 20 °) inclination with regulation on above-below direction, so that the glory hole upper end is inclined to described circumferencial direction one side (clockwise direction) with respect to the glory hole lower end, that is, make the ejection combustion gas that is applied in the inclination of described corner α be inclined on the direction that rotatablely moves.Like this, the combustion gas ejection axis A2 that draws from the upper end of glory hole 31 deviates from radial outside for the combustion gas ejection axis A1 that draws from the lower end of glory hole 31, the inscribed circle S1 of the inscribed circle S2 of the combustion gas ejection axis A2 of upper end and the combustion gas ejection axis A1 of lower end is in a ratio of major diameter, can suppress the extension of flame towards the inboard more effectively like this.Thus, flame deviates from cooking bottom temperature sensor 6, makes flame be minimized the heat affecting that cooking bottom temperature sensor 6 produces, thereby can detect the temperature of cooking container P by cooking bottom temperature sensor 6 accurately.
In addition because corresponding to the glory hole 31 of incision-like, lie laterally than the flame of unfertile land expansion in above-below direction, therefore, increased and the auxiliary air that comes from the top between contact area, thereby reach good combustion.In addition, be not to be provided with on the glory hole 31 under the situation of angle of inclination beta, for improving in a single day height that the thermal efficiency reduces range 5, then the distance between the bottom surface of the upper end of glory hole 31 and cooking container P shortens, before the combustion reaction of the ejection combustion gas of coming out from the upper end of glory hole 31 finishes, flame promptly is contacted with the bottom surface of cooking container P and is cooled, thereby produces the bad problem of burning.On the other hand, as present embodiment, on glory hole 31, be provided with angle of inclination beta, then make the position step-down of upper end of glory hole 31, can elongate the distance between the bottom surface of the upper end of glory hole 31 and cooking container P like this.Thus, even reduce the height of range 5 to a certain extent, can not produce yet the burning bad, thereby can improve efficiency of combustion.
In addition, the glory hole opening surface 344 (inner peripheral surface of inner peripheral wall portion 341) that offers glory hole 31 is towards the top and form the taper seat of hole enlargement.Thus, between the outer surface and glory hole opening surface 344 of the upside of the flame of glory hole 31, guaranteed that like this, auxiliary air is successfully supplied near the part of glory hole 31 from the top towards the space of top expansion.Thus, can suppress flame and be stretched over the outside for obtaining auxiliary air, its result can suppress position deviation with the contacted flame in bottom surface of cooking container P to the outside, thereby can improve the thermal efficiency.
In addition, even glory hole opening surface 344 is not formed taper seat, as shown in Figure 4, if at the groove 345 that forms on the flame openings face 344 between each glory hole 31, auxiliary air then can be fed into through groove 345 glory hole 31 near, thereby can suppress flame for obtaining the problem that auxiliary air is stretched over the outside.Even glory hole opening surface 344 is being formed under the situation of taper seat, by being formed with the groove 345 between each glory hole 31, flammability also can be further improved.
As mentioned above, though for the present invention being applicable to the embodiment on the internal flame formula burner 3 that is provided with cooking bottom temperature sensor 6 is illustrated,, the present invention can be useful on the internal flame formula burner that is not provided with cooking bottom temperature sensor 6 equally.In this case, such as mentioned above, because the extension of flame towards the inboard suppressed effectively, therefore, even dwindle the internal diameter of burner to a certain extent, flame will can not produce the phase mutual interference at the central portion of burner inner space yet, thereby can realize the miniaturization of burner.
