Summary of the invention: technical problem to be solved in the utility model is that a kind of gas kitchen range fire cap with radiating ribs will be provided, and it can increase the length of fire output hole effectively, can make fire output hole heat radiation preferably on every side after stopping working, and reduce tempering phenomenon, and cost is lower.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises fiery lid, and described fiery lid is provided with radiating ribs, and radiating ribs is provided with fire output hole.
Described radiating ribs is positioned at fiery lid inboard.
Described every radiating ribs is provided with 2~5 fire output holes, the fire output hole center line at grade, and with the angle α of vertical direction be 10 °~45 °.
The number of described fire output hole is 2, and angle α is 15 °.
The number of described fire output hole is 3, and angle α is 20 °.
The number of described fire output hole is 4, and angle α is 30 °.
The number of described fire output hole is 2, and angle α is 30 °.
The number of described fire output hole is 2, and angle α is 40 °.
The number of described fire output hole is 3, and angle α is 15 °.
The number of described fire output hole is 3, and angle α is 40 °.
The utility model is compared the beneficial effect that is produced with background technology:
1, be provided with radiating ribs because the utility model adopts on fiery lid, radiating ribs is provided with the structure of fire output hole, so it can increase the length of fire output hole effectively, can make fire output hole heat radiation preferably on every side after stopping working, and reduce tempering phenomenon, and cost is lower.
The specific embodiment: referring to accompanying drawing 1, Fig. 2, shown in Figure 3, present embodiment comprises fiery lid 1, and fiery lid 1 is provided with radiating ribs 2, and radiating ribs 2 is provided with fire output hole 3.It is 2~8mm that radiating ribs 2 is exposed fiery lid 1 length; The fire lid is installed on the burner 4, is changed into little fire or closed fire by big fire when burning, the part that radiating ribs 2 is exposed fiery lid 1 contacts with air, can comparatively fast carry out heat exchange, so just plays radiating effect, and the combustion gas in the fire output hole 3 is difficult to reach the temperature of catching fire; Radiating ribs 2 is provided with fire output hole 3, has increased the length of fire output hole 3, and burned flame is difficult to pass, and so just plays the generation that has reduced tempering, makes burning more stable.After adopting radiating ribs 2 structures, under the length condition that equates fire output hole 3, can alleviate the weight of whole fire lid, save cost.
