Description

Technical Field

[0001] The present invention relates to the technical field of kitchen utensils, and particularly to a burner cap, a burner, and a gas stove. Background Art

[0002] A gas stove is a commonly used kitchen utensil in daily life. Among them, the burner is the core component of the gas stove. The burner generally includes a burner head and a burner cap provided on the burner head. After introducing gas and air into the mixing chamber of the burner head through the injection port of the burner head for mixing, the mixed gas in the mixing chamber is then transported to the flame holes of the burner cap through the air flow channel for combustion.

[0003] However, the manufacturing process of the burner cap of the traditional burner generally uses brass forging, and then the flame holes are machined. The depth of the flame holes of the burner cap manufactured by this manufacturing process is generally relatively shallow. When the combustion conditions change, flashback is likely to occur, and the extinguishing noise is large when turning off the fire, and even flashback explosion may occur. If a boss is deliberately added to increase the depth of the flame holes, the forging process will become complicated, the machining difficulty will increase, the manufacturability will decrease, and at the same time, the material will be increased, resulting in an increase in cost.

Detailed implementation manners

[0049] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0050] See also Figure 1 , Figure 1 The schematic diagram of the structure of a burner in one embodiment of the present invention is shown. The burner provided in one embodiment of the present invention includes a burner head 200 and a fire cover 100 disposed on the burner head 200. After the gas and air are introduced into the mixing chamber of the burner head 200 through the injection port of the burner head 200 for mixing, the mixed gas in the mixing chamber is transported to the fire hole 201 of the fire cover 100 through the air flow channel 111 for combustion.

[0051] The fire cover of a traditional burner is generally forged from brass, and then the fire hole is machined out, and the depth of the fire hole is relatively small. When the burner adjusts the firepower from large to small or turns off the fire, the gas flow rate gradually decreases, and the flow rate also decreases. When the flow rate is less than the combustion speed, it is easy to backfire and an explosion sound occurs. The fire cover 100 of the burner of the present invention is made of sheet metal, and the fire hole 201 is also formed by pressing the sheet metal, so that a deeper fire hole 201 can be easily formed. Since the fire hole 201 is deep, the temperature of the fire hole 201 can be rapidly reduced as the firepower decreases, and the flame will be extinguished as soon as it enters the fire hole 201. Therefore, there will be no backfire to the mixing chamber, resulting in a backfire explosion, which can effectively improve the safety of the burner. The following is a detailed description of the specific implementation of the fire cover 100 of the present invention.

[0052] See also Figures 2 to 8 , shows a schematic diagram of the structure of the fire cover 100 of the first embodiment of the present invention. The fire cover 100 provided in the first embodiment of the present invention comprises a mounting seat 10 and a fire hole plate 21a, wherein the mounting seat 10 comprises a mounting plate 11 and an inner ring tube 12, wherein one end of the inner ring tube 12 is fixedly connected to the mounting plate 11, and the mounting plate 11 is provided with a plurality of air flow channels 111, each of which surrounds the inner ring tube 12; the fire hole plate 21a is a semi-enclosed structure made of sheet metal and open on one side, wherein the open side of the fire hole plate 21a abuts against the outer peripheral surface of the inner ring tube 12 so that the fire hole plate 21a and the inner ring tube 12 enclose a fire hole 201 with two ends through, and one end of the fire hole 201 is butted against and connected to the air flow channel 111.

[0053] Specifically, the burner cap 100 is used to cooperate with the burner head 200 of the burner. The mounting plate 11 covers the mixing chamber of the burner head 200. The air flow channel 111 on the mounting plate 11 is communicated with the mixing chamber. A central hole 101 is provided in the middle of the mounting plate 11 for supplementing secondary air. One end of the inner ring cylinder 12 is butted against the periphery of the central hole 101. The burner hole plate 21a has a semi-enclosed structure with an opening on one side and can enclose with the inner ring cylinder 12 to form a vertically penetrating burner hole 201. The lower end of the burner hole 201 is butted and communicated with the air flow channel 111. After the gas and air are introduced into the mixing chamber through the ejector port of the burner head 200 for mixing, the mixed gas in the mixing chamber is then transported to the burner hole 201 through the air flow channel 111 for combustion. Among them, the number of burner holes 201 is the same as the number of air flow channels 111, and the cross-sectional shape of the burner hole 201 is adapted to the cross-sectional shape of the air flow channel 111. Correspondingly, the burner hole plate 21a can be formed into different semi-enclosed structures by pressing sheet metal parts according to actual needs. For example, it can be U-shaped, C-shaped, V-shaped, etc. The mounting seat 10 and the burner hole plate 21a can both be made of sheet metal parts. Optionally, the sheet metal part can be made of nickel-chromium alloy material, which can withstand high temperatures, is not easy to rust, and can effectively extend the service life.

[0054] For example, in this embodiment, a plurality of air flow channels 111 are evenly and spacedly arranged around the periphery of the central cavity of the mounting plate 11. Correspondingly, a burner hole plate 21a is provided on the mounting plate 11 corresponding to each air flow channel 111, and the burner hole 201 of each burner hole plate 21a is communicated with the corresponding air flow channel 111. The plurality of burner hole plates 21a are combined into an annular burner cap body 20. As Figure 3 and Figure 5 shown, the burner cap body 20 further includes a plurality of connecting plates 22 having the same number as the burner hole plates 21a. The open sides between any two adjacent burner hole plates 21a are connected by a connecting plate 22, and each connecting plate 22 is attached to the outer peripheral surface of the inner ring cylinder 12. During actual production and manufacturing, a plurality of alternately arranged burner hole plates 21a and connecting plates 22 can be stamped on a long strip of sheet metal plate first, and then the long strip of sheet metal plate is enclosed into a ring and its two ends are welded together to obtain the annular burner cap body 20 as shown in Figure 5 shown. Of course, in other embodiments, the burner cap body 20 may also only include a plurality of burner hole plates 21a that are independent and separately arranged. During assembly, each burner hole plate 21a is respectively installed at the corresponding position of the mounting plate 11.

[0055] The burner cap 100 of the present invention has the following beneficial effects compared with the background art: The above-mentioned burner cap 100 is processed by a sheet metal part to form a semi-enclosed burner hole plate 21a with an opening on one side. The burner hole plate 21a is installed on the mounting plate 11. A burner hole 201 is formed by enclosing between the burner hole plate 21a and the inner ring cylinder 12, and the burner hole 201 is communicated with the air flow channel 111. The manufacturing process of the entire burner cap 100 is simple; and since the burner hole 201 is formed by sheet metal pressing, during processing, only a sheet metal plate with a corresponding size needs to be selected to easily process burner holes 201 with different depths, so that the depth of the burner hole 201 is not restricted by the manufacturing process, and burner holes 201 with different depths can be easily processed according to the combustion conditions of the test; and compared with the burner cap of a traditional burner forged from brass, brass is a relatively precious non-ferrous metal with limited natural resources, so the material cost is relatively high. However, the burner hole 201 of the burner cap 100 of the present invention is made of a sheet metal part, the manufacturing process is simple, the sheet metal raw materials are commonly available, and the cost is low. Therefore, even when the depth of the burner hole 201 is increased, the cost will not increase significantly.

[0056] Further, as Figure 6 shown, in the first embodiment, the burner hole plate 21a includes an end plate 211 disposed opposite to the inner ring cylinder 12, and side plates 212 extending from opposite sides of the end plate 211 toward the inner ring cylinder 12. The end plate 211 and the two side plates 212 enclose a U-shaped semi-enclosed structure. The burner hole plate 21a is arranged in a U shape, with a simple structure and easy to form; at the same time, the cross-section of the burner hole 201 is strip-shaped, which can be well adapted to the strip-shaped air flow channel 111.

[0057] Further, as Figure 2 shown, in the first embodiment, an outward flanging 121 is provided on the outer peripheral edge of the other end of the inner ring cylinder 12, and the burner hole plate 21a is clamped between the outward flanging 121 and the mounting plate 11 for limiting. Specifically, after the burner hole plate 21a and the mounting plate 11 are assembled, the outward flanging 121 is formed at the top end of the inner ring cylinder 12 through a flanging process, and the top inner edge of the burner hole plate 21a is pressed tightly by the outward flanging 121, which can ensure the assembly stability between the mounting seat 10 and the burner hole plate 21a.

[0058] Please refer to Figures 9 to 11 , which shows a schematic structural diagram of the burner cap of the second embodiment of the present invention. The burner cap 100 provided by the second embodiment of the present invention includes a mounting seat 10 and a burner hole plate 21b. The mounting seat 10 includes a mounting plate 11. A plurality of air flow channels 111 are provided on the mounting plate 11. The burner hole plate 21b is a fully enclosed structure made of a sheet metal part to construct a burner hole 201 that penetrates through both ends. One end of the burner hole 201 is docked and communicated with the air flow channel 111.

[0059] The fire hole plate 21b in the second embodiment and the fire hole plate 21a in the first embodiment are both made of sheet metal. The difference is that the fire hole plate 21a in the first embodiment is a semi-enclosed structure with an opening on one side, which needs to abut against the outer peripheral surface of the inner ring barrel 12 to construct the through-fire holes 201 at both ends. The fire hole plate 21b in the second embodiment is a fully enclosed structure, which can construct the through-fire holes 201 at both ends by itself. The manufacturing processes of the fire hole plates 21a and 21b in the above two embodiments are simple. During processing, only a sheet metal plate with a corresponding size needs to be selected to easily process the fire holes 201 with different depths, so that the depth of the fire holes 201 is not restricted by the manufacturing process, and the fire holes 201 with different depths can be easily processed according to the combustion conditions of the test. Moreover, the sheet metal raw materials are commonly available and the cost is low. Therefore, even when the depth of the fire holes 201 is increased, the cost will not increase significantly.

[0060] Further, please refer to Figures 9 to 11 In the second embodiment, the mounting seat 10 further includes an inner ring cylinder 12. One end of the inner ring cylinder 12 is fixedly connected to the mounting plate 11, and each air flow channel 111 surrounds the inner ring cylinder 12. A groove 122 is provided on the outer peripheral surface of the inner ring cylinder 12. The fire hole plate 21b includes an end plate 211 opposite to the inner ring cylinder 12, side plates 212 extending from opposite sides of the end plate 211 towards the inner ring cylinder 12, and positioning plates 214 provided on the sides of the side plates 212 away from the end plate 211. The two positioning plates 214 are closed together to form a positioning portion, and the positioning portion is in positioning cooperation with the groove 122. During assembly, the top of the fire hole plate 21b is inserted into the groove 122 of the inner ring cylinder 12, and the assembly and fixation between the fire hole plate 21b and the inner ring cylinder 12 are realized through the positioning cooperation between the positioning portion and the groove 122, and the operation is simple and convenient. In addition, in order to ensure the assembly stability of the fire hole plate 21b, optionally, at least two grooves 122 are provided on the outer peripheral surface of the inner ring cylinder 12 in the axial direction corresponding to each fire hole plate 21b.

[0061] Further, in the second embodiment, a flanging 121 is provided on the outer peripheral edge of the end of the inner ring cylinder 12 away from the mounting plate 11, and the flanging 121 cooperates with the mounting plate 11 to limit the fire hole plate 21b. Specifically, after the fire hole plate 21b and the mounting plate 11 are assembled, the flanging 121 is formed at the top end of the inner ring cylinder 12 through a flanging process, and the inner edge of the top of the fire hole plate 21b is pressed by the flanging 121, which can ensure the assembly stability between the mounting seat 10 and the fire hole plate 21b.

[0062] Further, please refer to Figure 6 and Figure 10, in the first embodiment and the second embodiment, at least one of the two side plates 212 is provided with a width-limiting convex platform 213 protruding towards the other, and the width-limiting convex platform 213 is used to limit the width between the two side plates 212. By providing the width-limiting convex platform 213, the width of the flame holes 201 of each flame hole plate 21a (or flame hole plate 21b) can be accurately ensured, ensuring combustion stability; at the same time, the consistency of mass production can also be ensured. Specifically, the width-limiting convex platform 213 can be integrally formed on the side plate 212 by sheet metal stamping process. Optionally, as Figure 6 and Figure 10 shown, the two side plates 212 are respectively provided with width-limiting convex platforms 213, and the two opposite width-limiting convex platforms 213 are in contact with each other. By providing the width-limiting convex platforms 213 on both side plates 212, in this way, the protruding height of the width-limiting convex platform 213 on each side plate 212 can be correspondingly reduced, thereby avoiding the wrinkling of the plate surface of the side plate 212 during the stamping process and ensuring the product quality. Among them, the number of width-limiting convex platforms 213 on each side plate 212 can be set according to actual needs. For example, in this embodiment, each side plate 212 is provided with two width-limiting convex platforms 213.

[0063] Furthermore, please refer to Figure 7 and Figure 11 , in the first embodiment and the second embodiment, the air flow channels 111 are arranged at intervals and evenly on the mounting plate 11, and the number of the flame hole plates 21a (or 21b) is the same as that of the air flow channels 111 and they are arranged in one-to-one correspondence; a plurality of positioning convex platforms 112 are provided on the upper end surface of the mounting plate 11, and the positioning convex platforms 112 and the air flow channels 111 are alternately arranged along the circumferential direction of the mounting plate 11, and the flame hole plate 21a (or flame hole plate 21b) is clamped between two adjacent positioning convex platforms 112. The adjacent two flame hole plates 21a (or flame hole plates 21b) can be evenly spaced apart by the positioning convex platforms 112, so as to ensure that a plurality of flame holes 201 can be evenly and spacedly arranged on the periphery of the central hole 101, and further ensure that the burner can emit fire evenly during operation, making the combustion more uniform; at the same time, the consistency of mass production can also be ensured.

[0064] Furthermore, in the first embodiment and the second embodiment, the shapes of the projections of the respective flame holes 201 on the mounting plate 11 are all strip-shaped, and a plurality of flame holes 201 are arranged radially on the outer periphery of the central hole 101. In this way, the flame holes 201 are arranged radially from the center to the periphery, further improving the combustion effect. In order to ensure that the flame holes 201 can be evenly arranged radially, as Figure 3 and Figure 11 shown, each positioning convex platform 112 is arranged as an oblong structure with one end narrow and the other end wide, and the narrow end of the positioning convex platform 112 is close to the periphery of the central hole 101, so as to enable a certain included angle to be maintained between two adjacent flame hole plates 21.

[0065] Further, please refer to Figure 4 , Figure 8 and Figure 9 . In the first and second embodiments, the burner cap 100 further includes a positioning cylinder 30. A positioning foot 32 is provided on one side of the positioning cylinder 30 that cooperates with the mounting plate 11, and a slot 113 that is inserted and cooperates with the positioning foot 32 is provided on the mounting plate 11. Specifically, the positioning cylinder 30 can be made of a sheet metal part. A plurality of positioning grooves 31 are formed by sheet metal pressing on the peripheral surface of the positioning cylinder 30. The positioning grooves 31 are open grooves that open towards the center of the positioning cylinder 30. Specifically, as shown in Figure 8 , the positioning groove 31 is a U-shaped groove adapted to the burner hole plate 21a. By positioning and cooperating the positioning groove 31 with the burner hole plate 21a, the installation stability of the burner hole plate 21 can be further ensured. During assembly, by inserting the positioning foot 32 into the slot 113, rapid positioning and assembly between the positioning cylinder 30 and the mounting plate 11 can be achieved, and the operation is simple and convenient. Optionally, the slot 113 penetrates the mounting plate 11 along the thickness direction of the mounting plate 11. After the positioning foot 32 is inserted into the slot 113, the end of the positioning foot 32 passes through the bottom surface of the mounting plate 11, and then the positioning foot 32 is pressed and riveted open towards one side, which can further ensure the installation reliability between the positioning cylinder 30 and the mounting plate 11. Optionally, a plurality of positioning feet 32 are provided, and the plurality of positioning feet 32 are spaced apart and evenly arranged along the circumferential direction of the bottom of the positioning cylinder 30. Correspondingly, a plurality of slots 113 are spaced apart and evenly arranged along the circumferential direction of the outer edge of the mounting plate 11, and the positioning feet 32 and the slots 113 are inserted and cooperated with each other one by one, which can further ensure the installation stability.

[0066] Further, please combine Figure 2 , Figure 4 and Figure 9 . In the first and second embodiments, the burner cap 100 further includes an outer ring cylinder 40 disposed around the periphery of the positioning cylinder 30. Inner flanges 41 are respectively provided on the inner peripheral edges of the opposite ends of the outer ring cylinder 40. The mounting base 10, the burner hole plate 21a (or the burner hole plate 21b) and the positioning cylinder 30 are clamped between the two inner flanges 41, and the two inner flanges 41 cooperate with each other to limit the mounting base 10, the burner hole plate 21a (or the burner hole plate 21b) and the positioning cylinder 30.

[0067] Specifically, after the mounting base 10, the burner hole plate 21a (or the burner hole plate 21b) 20 and the positioning cylinder 30 are assembled, the outer ring cylinder 40 is sleeved around the periphery of the positioning cylinder 30, and then the inner flanges 41 are respectively formed at both ends of the outer ring cylinder 40 through a flanging process, so that the entire periphery of the burner cap 100 can be edge-wrapped, making the overall assembly of the burner cap 100 more reliable.

[0068] The following takes the burner cap 100 in the first embodiment as an example to introduce its specific assembly process:

[0069] First, install the positioning cylinder 30 on the mounting plate 11. Specifically, the positioning feet 32 of the positioning cylinder 30 can be inserted into the slots 113 of the mounting plate 11. After the bottom ends of the positioning feet 32 pass through the slots 113, they are riveted and opened, so that the positioning cylinder 30 can be fastened to the mounting plate 11. A receiving cavity for receiving the fire cap body 20 is defined between the positioning cylinder 30 and the inner ring cylinder 12. Then, the fire cap body 20 is integrally assembled into the receiving cavity. Each fire hole plate 21a is inserted into the corresponding positioning groove 31 on the positioning cylinder 30. The fire hole plates 21a can be evenly spaced apart by the positioning grooves 31 and the positioning bosses 112 on the mounting plate 11. The air flow channel 111 is communicated with the fire holes 201. Then, a flanging 121 is formed at the top end of the inner ring cylinder 12, and the top inner edge of the fire cap body 20 is pressed tightly by the flanging 121. Finally, the outer ring cylinder 40 is sleeved around the periphery of the positioning cylinder 30, and inner flangings 41 are respectively formed at both ends of the outer ring cylinder 40 to wrap the periphery of the entire fire cap 100. The entire assembly process is simple and the assembly stability is high. The mounting base 10, the fire cap body 20, the positioning cylinder 30, and the outer ring cylinder 40 are all made of sheet metal parts, which can effectively reduce the production cost.
