Description
Technical Field
The invention relates to the field of gas stoves, in particular to an inner ring fire cover of an anti-blocking combustor.
Background
The existing gas burner generally comprises an inner ring and an outer ring, wherein ignition holes are formed in the inner ring and the outer ring of the inner ring, and the inner ring and the outer ring of the inner ring are used for generating flame, maintaining the flame and the like together with elements such as an ignition needle, a thermocouple and the like. The traditional inner ring fire cover has the risk that long-term greasy dirt of the bottom of the pan enters the ignition hole to block the ignition hole. Therefore, the existing inner ring fire cover is generally integrally formed with a protective umbrella, and the ignition needle is protected by the protective umbrella. The invention of China patent with application number 201010135138.4 (application publication number CN 101832560A) discloses a central fire cover of a gas stove and a burner using the central fire cover, wherein the central fire cover comprises a cylinder body and an end cap arranged on the cylinder body, one side of the end cap is provided with a protective cover (namely a protective umbrella) for covering an ignition needle, and correspondingly, the ignition needle is positioned below the protective cover to play a role in protection. However, when oil stains, water drops and the like drop to the top surface of the protective umbrella, the oil stains, the water drops and the like can enter ignition holes below the protective umbrella along the wall, so that the ignition holes are blocked, and the ignition failure is caused.
Disclosure of Invention
The invention aims to solve the technical problem of providing an inner ring fire cover of an anti-blocking burner, which can effectively avoid blocking of an ignition hole.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides an anti-blocking burner inner ring fire lid, includes the fire lid body of tube-shape and locates the end cap on this fire lid body top, and this end cap encloses with the fire lid body and establishes and form the air mixing chamber, and one side of this end cap is provided with the protection umbrella, has seted up the play fire hole with above-mentioned air mixing chamber intercommunication on the lateral wall of the fire lid body of this protection umbrella below, its characterized in that is provided with the anti-blocking recess of inwards sunken on the lateral wall of the fire lid body of protection umbrella below, and the both ends of this anti-blocking recess are located the both sides of protection umbrella respectively.
Preferably, an auxiliary ignition hole communicated with the air mixing cavity is formed in the wall of the anti-blocking groove. Through setting up supplementary ignition hole, when the ignition hole blocks up like this, the flame on this supplementary ignition hole of accessible carries out supplementary ignition, in addition, the flame on the supplementary ignition hole can burn the liquid drop that drops from the protection umbrella, realizes self-cleaning, avoids the overflow to block up anti-blocking groove, thoroughly stops the liquid to overflow from anti-blocking groove and gets into the possibility of ignition hole once more.
Preferably, the anti-blocking groove is formed by extending the side wall of the fire cover body horizontally inwards, and the auxiliary ignition hole is formed in the groove wall opposite to the opening of the anti-blocking groove. Therefore, the liquid drops can stably stay in the anti-blocking groove after flowing into the anti-blocking groove, and the auxiliary ignition holes are arranged on the groove wall opposite to the opening of the anti-blocking groove, so that flame sprayed out of the auxiliary ignition holes can be sprayed out of the notch of the anti-blocking groove better, and the influence of the liquid drops entering the anti-blocking groove on the combustion of the flame in the auxiliary ignition holes can be avoided.
Further, preferably, the pore canal of the auxiliary ignition hole extends horizontally along the groove wall of the anti-blocking groove, so that flame of the auxiliary ignition hole can be directly sprayed on the notch of the anti-blocking groove, the ignition success rate of the auxiliary ignition hole can be improved, and in addition, the overflow liquid entering the anti-blocking groove can be directly burnt, so that part of the overflow liquid is burnt and removed by flame sprayed by the auxiliary ignition hole before the overflow liquid does not enter the anti-blocking groove.
Further, preferably, the protection umbrella and the end cap are integrated, the pore canal of the auxiliary ignition hole extends vertically downwards along the groove wall of the anti-blocking groove, so that flame of the auxiliary ignition hole directly sprays the top wall of the anti-blocking groove, the top wall of the anti-blocking groove is the end cap, the protection umbrella can be preheated by the upward direct spraying flame of the auxiliary ignition hole, and liquid overflows to the protection umbrella to evaporate due to high temperature, so that fluidity is lost.
Preferably, the longitudinal section of the anti-blocking groove is square or circular arc.
Preferably, the ignition hole is formed below the anti-blocking groove, the lower side edge of the notch of the anti-blocking groove is sunken downwards to form an auxiliary anti-blocking groove, the auxiliary anti-blocking groove is opposite to the protective umbrella, and part of pore channels of each ignition hole at the upper part are positioned in the auxiliary anti-blocking groove. By arranging the auxiliary anti-blocking groove, the area of a fire outlet of an ignition hole in the upper part of the fire cover body is increased, so that the surface tension of liquid at the fire outlet is reduced, and the ignition hole is prevented from being blocked by overflow liquid.
Preferably, the outer peripheral side of the bottom surface of the protective umbrella is recessed upward to form an annular diversion trench. Therefore, overflowed liquid is guided into the guide groove when flowing to the bottom surface of the protective umbrella along the wall of the protective umbrella, and the phenomenon that the overflowed liquid is dropped to the ignition needle from the middle part of the bottom surface of the protective umbrella to affect ignition is avoided.
Preferably, the anti-blocking groove is formed by inwards sinking the upper end of the fire cover body corresponding to the protective umbrella, so that liquid drops flowing down along the wall on the protective umbrella can directly flow into the anti-blocking groove, and the liquid drops are thoroughly prevented from flowing into the ignition hole or the fire outlet hole along the surface of the fire cover body beyond the anti-blocking groove.
Compared with the prior art, the invention has the advantages that: the anti-blocking grooves are formed in the inner ring fire cover, and the two ends of the anti-blocking grooves are respectively positioned at the two sides of the protective umbrella, so that when oil stains, water drops and the like drop onto the top surface of the protective umbrella and flow down along the surfaces of the protective umbrella wall and the fire cover body, the oil stains, the water drops and the like cannot flow into the ignition holes and flow into the anti-blocking grooves, and the ignition holes are effectively prevented from being blocked due to the fact that the water drops drop into the ignition holes.
