Definitions
- the invention relates to a gas burner for a gas hob, the a Burner part having an upwardly open mixing chamber through a burner cap is covered, on which a cap is located.
- a generic gas burner which with a burner part is mounted on an upper side of the hob plate.
- the Burner part has an upwardly open mixing chamber, which by a Burner cap is covered.
- a Burner cap In the burner cap is a variety of Flame outlet openings formed on the side edge.
- a lid cap On the Burner lid is a lid cap, with the burner cap in loose plant is.
- the object of the invention is to provide a gas burner with a To provide burner cover, in a simple way with a Cover cap is connected.
- the object of the invention is a gas burner with the features of claim 1 or by a burner cap according to the Claim 16 solved.
- the gas burner a separate Associated with connecting element, which covers the lid with the Burner cap connects. Due to the separate training of Locking element can only the locking element in terms adapted to its locking function in shape and material, without changing the entire burner cap and / or the cap would have to be.
- the locking element between the lid cap and be arranged the burner cover Due to this arrangement between Cover cap and burner cap is the locking element largely invisible to the user, for reasons of appearance and cleaning is preferred.
- the locking element is in essentially positively with the burner cover and / or with the Cover cap engaged.
- a largely play-free storage ensures the cap on the burner cap.
- Voltages or Forces when connecting the burner cap with the lid cap may arise from the separate locking element be absorbed without looking at the burner cap and / or transferred to the lid cap.
- the lid cap held captive on the burner cover. Such tensions and Forces adversely affect coatings of the lid cap.
- they can change the shape of the geometry of the lid cause a flow pattern of the outflowing Gas / air mixture can change unfavorably.
- the separate locking element consists of a resilient material. This allows forces and Tensions when connecting the lid to the lid cap arise, received in the first place by the locking element and not from the lid or lid cap.
- the elastic Properties of the locking element are reinforced when the Locking element is designed as a spring element.
- the locking element on the circumference is arranged on the burner cover. This allows a height of out the burner cap and the lid cap existing unit be reduced advantageous.
- the burner cap have an annular groove for holding the locking element. These can at least partially circumferentially move the burner cover. This can already during assembly, the locking element self-holding pre-assembled in the burner cover.
- the lid cap may preferably have a peripheral edge, which Burner cover circumferentially limited.
- In the peripheral edge of Cover cap may be formed an annular groove, at least partially circumferentially moves the lid cap.
- the locking element can be arranged, whereby the cover cap connected to the burner cap.
- the annular groove of the lid cap and the annular groove of the burner cap can cooperate in such a way that they form the almost closed space in which the Locking element is arranged.
- an inner diameter of the peripheral edge of the lid cap substantially an outer diameter of the peripheral edge of the Burner cap or be slightly larger.
- the Cover cap can therefore almost free of play in the radial direction on the Be mounted burner cap.
- the peripheral edge of the lid cap is opposite to a Bottom of the burner cap reset or substantially flush with the bottom of the burner cap. This will be to the bottom protruding edges are avoided, which are characterized Flame outlets could catch passing flames. A Impairment of the flame image of the gas burner is thus prevented.
- Figure 1 in a side sectional view of a burner cap with indicated burner part
- FIG. 2 shows a detail X from FIG. 1;
- Figure 3 is an exploded view of the burner cap, the lid cap and the locking element
- Figure 4 corresponding to Figure 3 is a view of the burner cap with mounted locking element and removed cover cap.
- a gas burner for a gas hob is shown, the one dash-dotted lines indicated burner part 1 has.
- the cup trained burner part 1 borders with its cylindrical side wall. 3 an upwardly open mixing chamber 5 for a gas / air mixture.
- On the upper edge of the side wall 3 is a burner cap 7, the Mixing chamber 5 closes.
- On the underside of the burner cap 7 is a Support ring 9 is formed.
- the burner cover is supported 7 on the upper edge of the cylindrical side wall 3 of the burner part. 1 from.
- In the support ring 9 are downwardly open recesses 11th incorporated, which serve as flame outlet openings and in Circumferentially arranged evenly spaced.
- the Burner cover 7 is formed as an aluminum injection molded part.
- the support ring 9 of the burner cap 7 is radially outward in one Edge flange 13 via.
- a Ring groove 15 is formed, which moves the burner cover 7.
- a later described Locking element 17 is supported.
- a disk-shaped Lid cap 19 made of a steel sheet.
- the lid cap 19 has a downwardly beaded peripheral edge 21. Between the circumference beaded peripheral edge 21 and the peripheral wall 14 of the lid 7 is an almost closed gap 25 is formed, in which the Locking element 17 is arranged.
- the beaded peripheral edge 21 of the lid cap 19 is like a radial formed inwardly directed annular groove, which is the annular groove 15th opposite.
- the locking element 17 is shown in Figure 3 as a C-shaped open Clamping ring formed from a spring steel wire, like a Spring element acts.
- the clamping ring 17 is initially during assembly inserted into the annular groove 15 of the burner cap 7, as shown in FIG. 4 is shown. Accordingly, the burner cap 7 between the Spring legs of the clamping ring 17 clamped.
- the clamping ring 17 is therefore self-holding pre-assembled in the annular groove 15 of the burner cover 7.
- By doing in the mounting state shown in FIG. 4 protrudes in the clamping ring 17th radially outwardly bent latch portion 27 and the two ends 29 of the clamping ring 17 radially from the annular groove 15 of the burner cover. 7 out.
- the side wall 14 of the burner cap 7 slightly over a gap s by about 0.3 mm from the circumferential one Limiting edge 23 of the lid cap 19 spaced.
- the lid cap 19 is therefore slightly floating in a radial direction on the Burner cover 7 stored.
- thermally induced different thermal expansion of the burner cover or the Cover cap 19 are balanced without between the two parts Tensions arise.
- the lid cap 19 can be detachable, or if necessary, be permanently connected to the burner cover. However, one is preferred permanent connection of the cover cap 19 with the burner cover 7. The Inseparable connection is achieved when the between the burner cap 7 and the lid cap 19 formed gap 25 to the outside in the is substantially closed.
- the lid cap according to the invention 19 are connected to the burner cover 7 without larger Tensions in the lid cap 19 or in the burner cap. 7 arise. Such tensions could cause a chipping or Tear off the enamel layer lead. On the other hand, such Tensions also changes in shape in the geometry of the burner cap 7 cause what a flow of the out of the mixing chamber. 5 escaping gas / air mixture and thus the flame image of Brenners negatively affected.
