Example 1
As shown in fig. 1 and 2, the present invention provides a stove fire cover 10, the surface of which has a main fire hole 11 and a flame stabilizing hole 21, wherein an outlet of the flame stabilizing hole 21 is disposed close to an outlet of the main fire hole 11, and an included angle α is formed between a gas flowing direction of the flame stabilizing hole 21 and a gas flowing direction of the main fire hole 11, and is greater than 90 ° (see fig. 2).
The gas in the flame stabilizing hole 21 and the gas in the main fire hole 11 flow out oppositely in the direction of the included angle alpha larger than 90 degrees, so that the gas flowing out from the flame stabilizing hole 21 is utilized to carry out turbulence on the gas in the main fire hole 11, and the flow speed of the gas flowing out from the outlet of the flame stabilizing hole 21 is utilized to reduce the flow speed of the gas flowing out from the outlet of the main fire hole 11, so that the flame stabilizing hole 21 has multiple functions of stabilizing flame, stabilizing flow, turbulent flow and the like on the main fire hole 11 at the same time, and the use function of the stove fire cover 10 is improved.
As shown in figure 1, the main fire hole 11 and the flame stabilizing hole 21 are oppositely arranged and are simultaneously positioned on the stove fire cover 10. In this embodiment, only a partial structural schematic diagram of the stove fire cover 10 provided with the main fire holes 11 and the flame stabilizing holes 21 is disclosed, and it should be particularly described that, except for the relative position layout of the main fire holes 11 and the flame stabilizing holes 21 on the stove fire cover 10, other structural features of the stove fire cover 10 in this embodiment are structural features existing in the prior art, and therefore, no further description is provided herein.
Example 2
The present embodiment further provides a stove fire cover 10, the structure of which is substantially the same as that of the stove fire cover 10 provided in embodiment 1, and as shown in fig. 5, an included angle α between the main fire holes 11 and the flame stabilizing holes 21 is also larger than 90 °.
The difference of the stove fire cover 10 of the embodiment is that the stove fire cover specifically comprises an inner ring fire cover 1 and an outer ring fire cover 2, and a main fire hole 11 and a flame stabilizing hole 21 are respectively arranged on the inner ring fire cover 1 and the outer ring fire cover 2.
Through setting up the fire hole of two kinds of types respectively on inner ring fire lid 1 and outer loop fire lid 2 to utilize the clearance between inner ring fire lid 1 and the outer loop fire lid 2, set up main fire hole 11 and steady flame hole 21 respectively at the surface of inner ring fire lid 1 and the internal surface of outer loop fire lid 2, thereby can realize the structural design of main fire hole 11 and steady flame hole 21 subtend setting more conveniently.
As shown in fig. 3 and 5, in the present embodiment, the main fire holes 11 are provided on the inner ring fire cover 1, and the flame stabilizing holes 21 are provided on the outer ring fire cover 2. Meanwhile, the stove fire cover 10 is also provided with auxiliary fire holes 22, the auxiliary fire holes 22 are also arranged on the outer ring fire cover 2, and the auxiliary fire holes 22 are arranged between two adjacent flame stabilizing holes 21 at intervals so as to improve the firepower on the outer ring fire cover 2.
Meanwhile, the surface of the outer ring fire cover 2 is also provided with a gas pipeline 23 extending towards the opening direction of the main fire hole 11, and the flame stabilizing hole 21 is arranged at the tail end position of the gas pipeline 23, so that on the premise of ensuring a certain gap between the inner ring fire cover 1 and the outer ring fire cover 2, the distance between the outlet of the flame stabilizing hole 21 and the main fire hole 11 is reduced as far as possible, and the flame stabilizing and turbulent effects of the flame stabilizing hole 21 on the main fire hole 11 are improved.
In the present embodiment, the outer fire cover 2 is not directly connected to the gas mixing chamber (not shown) of the gas cooker, but is connected to the gas supply channel 12 extending outward from the inner fire cover 1, so that the gas supply channel 12 connects the gas chamber 1a of the inner fire cover 1 and the gas chamber 2a of the outer fire cover 2 together, so that the gas in the gas mixing chamber is delivered into the gas chamber 2a of the outer fire cover 2 through the gas chamber 1a of the inner fire cover 1 and the gas supply channel 12.
Wherein, the air supply channel 12 is located at the upper surface position of the inner ring fire cover 1, and the air supply channel 12 extends horizontally outwards. Since the end of the gas supply channel 12 is connected to the outer ring fire cover 2, the outer ring fire cover 2 is disposed at a height relatively higher than that of the inner ring fire cover 1.
Preferably, as shown in fig. 4, a plurality of protrusions 13 protruding upward are provided on the upper surface of the inner fire cover 1, and the protrusions 13 are circumferentially and uniformly distributed along the circumferential direction of the inner fire cover 1. The gas chamber 1a of the inner ring fire cover 1 is formed inside the protruding portion 13, so that when one end of the gas supply passage 12 connected to the inner ring fire cover 1 side is directly connected to the protruding portion 13, the gas in the gas chamber 1a of the inner ring fire cover 1 can enter the gas supply passage 12 via the space inside the protruding portion 13.
These projections 13 can also be used as pan holders. Particularly, when the pan is placed above the fire cover 10 of the cooker, the top of the protrusion 13 is in direct contact with the bottom of the pan, so that the purpose of supporting the pan is achieved by the protrusion 13 at the top of the inner ring fire cover 1 without additionally arranging a pan support.
In addition, in the embodiment, the outer ring fire cover 2 only achieves the purpose of fixing the position relationship between the outer ring fire cover 2 and the inner ring fire cover 1 through the air supply channels 12 uniformly distributed between the inner ring fire cover 1 and the outer ring fire cover 2. The outer ring fire cover 2 of the stove fire cover 10 is not directly fixed and communicated with a gas mixing chamber of the stove, and the position fixation and the gas delivery are realized through a gas supply channel 12 extending from the inner ring fire cover 1. That is, the inner fire cover 1 is installed above the gas mixing chamber, the outer fire cover 2 is directly installed on the periphery of the inner fire cover 1, and the gas used in the outer fire cover 2 is delivered from the inner fire cover 1 through the gas supply channel 12.
The structure arrangement greatly changes the structure and the connection characteristics of the traditional stove fire cover 10, so that the gas mixing chamber only needs to be provided with the inner ring fire cover 1 for installation and connection, and the outer ring fire cover 2 does not need to be considered.
On this basis, as shown in fig. 5, the outer ring fire cover 2 should be disposed at a higher height than the inner ring fire cover 1 so that there is enough open space below the outer ring fire cover 2 to form a secondary air passage 10a at the open space for supplementing air to the inner ring fire cover 1. Compared with the traditional stove fire cover 10, the lower part of the outer ring fire cover 2 is provided with a gas chamber communicated to the gas mixing chamber, the outer ring fire cover 2 provided in the embodiment is fixed along the horizontal direction and communicated to the inner ring fire cover 1, so that the space below the outer ring fire cover 2 can be completely opened, and the defect that air is difficult to supplement and enter the inner ring fire cover 1 due to the shielding of the outer ring fire cover 2 in the traditional stove fire cover 10 is overcome.
In addition, because the outer ring fire cover 2 is higher than the inner ring fire cover 1, the outer ring fire cover can be closer to the bottom of a pot, and therefore, the energy collecting ring 24 is arranged on the outer surface of the outer ring fire cover 2 to collect the heat of the stove fire cover 10 and improve the heating efficiency.
As shown in fig. 6, it is a schematic view of a partial three-dimensional structure of the fire cover 10 of the cooking stove viewed from an oblique upward viewing angle. As can be seen from the figure, since the outer ring fire cover 2 is disposed higher than the inner ring fire cover 1, the gas pipe 23 is disposed on the lower surface 2b of the outer ring fire cover 2, and the gas pipe 23 is bent and horizontally extended after extending downward by a certain distance to further extend to the inside of the main fire hole 11 of the inner ring fire cover 1 (see fig. 5), so that the flame stabilizing hole 21 located at the end of the gas pipe 23 can extend into the inside of the outlet of the main fire hole 11. The structure enables the gas flowing out from the flame stabilizing hole 21 to completely and directly act on the gas flowing out from the main fire hole 11 in the opposite direction by arranging the flame stabilizing hole 21 further close to the main fire hole 11, thereby improving the functions of stabilizing the flow and turbulent flow of the main fire hole 11 by the flame stabilizing hole 21.
Of course, in the case that the gas pipe 23 provided with the flame stabilizing hole 21 completely extends into the main fire hole 11, the pipe diameter of the gas pipe 23 must be smaller than the corresponding hole diameter of the main fire hole 11 to avoid hindering the gas from flowing out of the main fire hole 11.
In addition, the embodiment provides only a preferred way to arrange the flame stabilizing holes 21, in other embodiments, the gas pipes 23 extending from the surface of the outer ring fire cover 2 may not directly extend into the main fire holes 11, but only be arranged near the main fire holes 11, and in this arrangement, the flame stabilizing holes 21 can also stabilize the flame, stabilize the flow and make the turbulence of the main fire holes 11.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
