Description
Technical Field
The utility model relates to a spare part technical field for the gas-cooker especially relates to a slot type external fire lid and combustor.
Background
The outer fire cover is a common part of a gas stove, and most of fire holes of the common outer fire cover are circular fire holes, grooving fire holes or the combination of the circular fire holes and the grooving fire holes. Most of slotted fire covers on the market are provided with convex parts on the upper surface, concave parts are arranged at corresponding positions, and the cutting grooves penetrate through the convex parts and the concave parts to form slotted fire holes.
For example, a chinese patent with CN206300196U publication discloses an outer fire cover of an energy-saving gas stove with a rotary flame, wherein a plurality of cutting fire holes are formed on the outer fire cover. However, this technique has some drawbacks: 1) for the flame that leaves that prevents flame, the fire lid wall is pressed close to one side of grooving fire hole, and this makes flame have one side to press close to the fire lid wall, leads to this face hardly to supply secondary air, and flue gas and operating mode all are difficult to the debugging. 2) The structure makes one side of the flame easy to burn to the surface of the fire cover, so that the surface temperature of the fire cover is raised, the fire cover is easy to deform after a long time and is not durable enough. 3) Only a few fire grooves can be arranged, otherwise, flame interference of fire holes of the two cutting grooves is easily caused, and the smoke is high; in addition, the small number of fire grooves can cause insufficient area of fire holes and overlong flame, so that the pot support and the like need to be heightened. These all cause the performance to be difficult to debug and the thermal efficiency to be low. 4) Easy to block the notch fire hole due to the overflow of the soup, causing the user to need to clean often, the user experience is poor.

As a further explanation of the above solution, the opening of the second notch fire hole is higher than the plane of the inner ring surface.
As a further explanation of the above solution, the inclination angle of the first inclined boss and the second inclined boss is between 30 ° and 75 °.
As a further explanation of the above scheme, the first slot fire hole and the second slot fire hole are rectangular notches arranged obliquely, an inclination angle of the first slot fire hole is consistent with an inclination angle of the first inclined boss, and an inclination angle of the second slot fire hole is consistent with an inclination angle of the second inclined boss.
A burner, comprising: the base is arranged on the upper part of the furnace end and the lower part of the furnace end on the base, and the central fire cover and the outer fire cover are respectively arranged on the upper part of the furnace end and the lower part of the furnace end; characterized in that the outer fire cover is as described above.
The utility model has the advantages that:
the secondary air can be fully supplemented to two sides of flame by arranging the outer ring surface and the inner ring surface which are arranged in the inverted V shape and respectively arranging the inclined bosses on the outer ring surface and the inner ring surface, so that the number of the grooved fire holes can be increased, the smoke can be effectively reduced, and the heat efficiency is high; and the overflow soup can be prevented from blocking the cutting fire hole or flowing through the burner.
And secondly, because the first grooving fire hole and the second grooving fire hole are higher than the plane where the corresponding inclined boss is located, flame is not easy to burn to the surface of the fire cover, the deformation caused by temperature rise is reduced, and the service life is prolonged.
And thirdly, as the first inclined boss and the second inclined boss are respectively inclined outwards and inwards, and the grooving fire holes are not upwards any more, the overflow soup can be better guided to the outside and is not easy to flow into the cooker, the overflow soup is not easy to block the fire holes, and the pain of users is reduced.
