Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
As shown in figure 1, the invention provides a stove fire cover, which comprises an inner ring fire cover 1 and an outer ring fire cover 2, wherein the inner ring fire cover 1 and the outer ring fire cover 2 are concentrically arranged and are respectively arranged above a stove base (not shown in the figure). The outer ring fire cover 2 and the stove base form a gas chamber in a surrounding manner, the outer ring fire cover 2 is also provided with three relatively independent fire transfer channels 2a, 22b and 22c, and the fire transfer channels are all hidden fire transfer structures and are used for transferring the flames burning on the inner ring fire cover 1 to the outer surface of the outer ring fire cover 2.
These three fire channels use the axis 10a of cooking utensils fire lid respectively as the circumference equipartition of center on outer ring fire lid 2, and the passageway cross sectional area of three fire channels is all inequality, is respectively: the fire transfer channel 22a is larger than the fire transfer channel 22b is larger than the fire transfer channel 22 c. Meanwhile, the three fire transfer channels are respectively provided with corresponding fire transfer holes 23, the fire transfer holes 23 are communicated to the gas chamber, the aperture of the fire transfer holes 23 is reduced along with the reduction of the channel section area of the correspondingly arranged fire transfer channels, that is, for the embodiment, the aperture sizes of the fire transfer holes 23 are respectively: the fire transfer holes of the fire transfer channel 22a are larger than the fire transfer holes of the fire transfer channel 22b are larger than the fire transfer holes of the fire transfer channel 22 c.
The traditional stove fire cover does not make any improvement aiming at the situation that the hidden type fire transmission structure with a specific size fails to ignite due to the change of gas pressure, and meanwhile, the hidden type fire transmission structure hidden inside the fire cover is compatible with different gas pressures, and the higher ignition success rate is ensured to be more difficult under various gas pressures. Therefore, according to the stove fire cover, the plurality of fire transmission channels with different sizes are simultaneously arranged on the outer ring fire cover 2, the fire transmission holes 23 with corresponding sizes are arranged according to the size specifications of the fire transmission channels, and the fire transmission holes are matched with the change of gas pressure, so that at least one fire transmission channel can be successfully ignited under the condition of different gas pressures, the fire transmission success rate of the stove fire cover is ensured, and the user experience is facilitated to be improved. Meanwhile, when a plurality of fire transfer channels are arranged, if more than two of the fire transfer channels are successfully ignited and transfer fire, the fire transfer efficiency of the fire cover of the stove can be improved.
In addition, due to the manufacturing and processing cost and the structural arrangement, the three fire transmission channels with different sizes are arranged on the outer ring fire cover 2 at the same time, so that the pressure fluctuation range of the conventional fuel gas can be basically covered. If more fire transfer channels are arranged, the success rate of fire transfer can be effectively ensured, but the manufacturing cost is correspondingly increased, and meanwhile, the fire transfer channels also occupy the arrangement space of the fire holes, so that the heating efficiency of the fire cover is influenced.
In addition, for the present embodiment, other external or internal structures of the inner ring fire cover 1 and the outer ring fire cover 2 are all within the scope of the prior art, and therefore, are not described herein again.
Example 2
This implementation provides an outer ring fire lid 2 structure of cooking utensils fire lid, its structure is roughly the same as that embodiment 1 provided, and the difference lies in: as shown in fig. 2, in the present embodiment, the outer ring fire cover 2 is further provided with a through hole 24 and a partition plate 25. The through hole 24 penetrates through the outer ring fire cover 2 in the horizontal direction, and two ends of the through hole extend to the outer surface and the inner surface of the outer ring fire cover 2 respectively. The partition 25 is disposed inside the through hole 24, and in the present embodiment, the partition 25 is disposed along the length direction of the through hole 24 to separate a plurality of relatively independent fire channels 22 in the through hole 24.
This cooking utensils fire lid through setting up perforating hole 24 and baffle 25 to separate a plurality of relatively independent biography fire passageways 22 in single through-hole structure, make these pass fire passageways 22 both keep apart relatively, can closely be close to again in space, thereby reduced and set up the occupation of a plurality of biography fire passageways 22 to cooking utensils fire lid surface space, other structures such as messenger's fire hole have sufficient setting space. The partition plate 25 in the present embodiment is fixed to the inner surface of the through hole 24 by welding, but in other embodiments, the partition plate 25 may be fixed by other detachable connection methods in the prior art, so as to facilitate replacement of the partition plate 25.
As shown in fig. 2 and 3, the through-hole 24 has a cylindrical shape and a circular channel cross-sectional shape. The partition 25 is composed of a plurality of partition units which are connected to each other at the position of the axis 24a of the through-hole 24 and are circumferentially arranged centering on the axis 24a of the through-hole 24. In the present embodiment, the partition plate 25 is composed of three partition plate units so as to divide the entire through-hole 24 into three fire transfer passages 22 along the axis 24a of the through-hole 24. The three fire transfer channels differ in channel cross-sectional area and, according to the principle of sector division, the included angle between the partition units is proportional to the channel cross-sectional area of the fire transfer channel 22 to which the included angle corresponds. That is, by adjusting the angular relationship between the partition units, the relationship of the passage sectional areas of the flame transfer passages 22 surrounded by the partition 25 and the through holes 24 can be changed simply, quickly, and directly. The structure can realize the quick adjustment of the size of each fire transmission channel 22, and is convenient for the processing and design of the fire cover of the stove.
Of course, in other embodiments, the shape of the through hole may be other shapes, and the plurality of baffle plate units may be connected at other positions in the through hole to separate the plurality of corresponding fire transfer passages in the through hole by the baffle plate units.
As shown in fig. 4 and 5, the outer ring fire cover 2 is further provided with an air inlet passage 26, and the air inlet passage 26 cuts through the inner surface of the through hole 24 in a direction perpendicular to the direction of the axis 24a of the through hole 24 and extends to the gas chamber 21 so that the gas in the gas chamber 21 enters the fire transfer passage 22 through the air inlet passage 26 to form the fire transfer hole 23 in the form of a long groove in the inner surface of the through hole 24. Further, a plurality of air intake passages 26 having the same shape are provided correspondingly to the single through hole 24, and these air intake passages 26 are provided at intervals in the direction of the axis 24a of the through hole 24. Specifically, the term "cutting through" the inner surface of the through-hole means that, when the intake passage structure is formed in the outer ring fire cover, the formed passage structure extends to the inner wall surface of the through-hole, and an opening is formed in the inner wall surface of the through-hole. Such processing is conventional in the art and will not be described further herein.
In the present embodiment, the air intake passage 26 completely cuts through the entire inner surface of the through-hole 24 in the circumferential direction of the through-hole 24, that is, a single air intake passage 26 can supply gas to all the fire transfer passages 22 in the through-hole 24, respectively, to serve as the fire transfer holes 23 of the fire transfer passages 22. As shown in fig. 6, taking the outer ring fire cover 2 of the present embodiment as an example, all the air inlet channels 26 may be directly machined at the through holes 24 during the machining process. Thereafter, the partition plates 25 are attached to divide the through-hole 24 into a plurality of flame transmitting passages 22. Specifically, the term "completely cutting" the entire inner surface of the through-hole means that, when the intake passage structure is processed, the passage structure forms an opening not only in the inner wall surface of the through-hole but also extends completely along the circumferential direction of the through-hole to the entire inner wall surface of the through-hole, that is, the intake passage 26 shown in the partially enlarged view of fig. 4.
On this basis, the width d of the intake passage 26 in the axial direction of the through-hole 24 is equal everywhere, and therefore the width d of the intake passage 26 forming the flame-transmitting hole 23 thereof is equal for any of the flame-transmitting passages 22 in the through-hole 24, the passage size of the intake passage 26 differing only in the length of the intake passage 26 for the corresponding flame-transmitting passage 22.
As shown in FIG. 4, for the air inlet channel 26 of the complete circular-cut through hole 24, since the width d of the air inlet channel 26 is equal, the determining condition for influencing the size of the fire transfer hole 23 formed by the air inlet channel 26 is the length of the air inlet channel 26, and the length of the air inlet channel 26 is in direct proportion to the angle formed between the two corresponding partition plate units, i.e. the larger the angle formed between the partition plate units, the larger the opening of the fire transfer hole 23 formed on the surface of the through hole 24 by the air inlet channel 26 in the fire transfer channel 22 is, and the complete direct proportion relationship is formed between the sizes, in this embodiment, referring to FIG. 2, the angles of the three fire transfer channels 22 separated by the partition plate 25 are α respectively1＝150°，α2＝120°，α3By the sector arc length formula, 90 °: the length l of the intake channel 26 corresponding to these three angles is known as l-n pi r/1801，l2And l3Respectively in direct proportion to the corresponding angles.
With the outer ring fire cover 2 having the above structure, it is not necessary to calculate in advance the relationship in the sizes of the fire holes 23 corresponding to the plurality of fire transfer passages 22 formed in the through hole 24 in the process of designing the structure of the fire cover. Because for these flame transfer passages 22, there is a proportional relationship between the size of the flame transfer holes 23 formed in the surface of the through-hole 24 through the intake passage 26 and the passage cross-sectional area of the flame transfer passage 22.
Therefore, the design difficulty of the fire cover of the cooker can be greatly reduced by the aid of the structure. Meanwhile, if the channel cross-sectional area difference of the plurality of fire transfer channels 22 is adjusted by changing the angle between the partition plate units, the size of the corresponding fire transfer hole 23 is also changed without additional structural adjustment.
Example 3
This implementation provides an outer loop fire lid 2 structure of cooking utensils fire lid, its structure is roughly the same as that embodiment 2 provided, and the difference lies in: as shown in fig. 6 and 7, in the present embodiment, the partition plate 25 is formed in a V shape to partition two complete fire transfer passages 22 in the through-hole 24. The width of the inlet channel 26, which is cut around the through-opening 24, is not equal in all places, but decreases as the channel cross-sectional area of the connected flame-conducting channel 22 decreases.
For example, in the present embodiment, the area of the flame transfer passage 22 above the through-hole 24 is small, and therefore the width d of the intake passage 26 is at this position2Relatively narrow, and the area of the flame transfer channel 22 below the through-opening 24 is relatively large, so that the width d of the inlet channel 26 is greater here1Is wider. Because the single air inlet channel 26 has two different widths, the secondary cutting can be adopted when the fire lid is actually processed.
This configuration further reduces the size of the fire transfer holes 23 in the relatively small-sized fire transfer passages 22 to further expand the range of gas pressures that can be covered by the different-sized fire transfer passages 22.
In addition, referring to fig. 6 in particular, the outer ring fire cover 2 is provided with two separate fire transfer channels 22 in addition to the through hole 24 and the partition plate 25 to separate the two fire transfer channels 22, and the two separate fire transfer channels 22 have relatively small channel cross-sectional areas and are respectively located at the left and right sides of the through hole 24. As shown in fig. 7, the two separate fire transfer passages 22 are also circumferentially cut by the inlet passage 26 to form a fire transfer hole 23 structure on the surface of the fire transfer passage 22.
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.
