Description

Technical Field

[0001] This application relates to the technical field of cooking equipment, and more particularly to a fire cap and a cooking utensil. Background Technology

[0002] Gas stoves are now ubiquitous in daily life, and the burner plays a major role in them.

[0003] In related technologies, burners typically have a copper core region and an outer ring region. The burner has an outer ring cavity corresponding to the outer ring region and a flame cap covering the outer ring cavity. The flame cap has several flame outlet slits. During use, the copper core region and the outer ring region are ignited, with the flame in the outer ring region being ejected outwards from the flame outlet slits.

[0004] However, during the use of burners, because the burner cap is usually made of sheet metal, the wall thickness of the burner cap is relatively thin and the depth of the flame outlet gap is relatively shallow, which makes it easy for backfire to occur during the combustion process and reduces the safety of use. Utility Model Content

[0005] This application provides a flame cap and a cooking appliance to solve the problem of backfire easily occurring during combustion in the prior art.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] In a first aspect, embodiments of this application provide a flame cover, including a main body and a cover;

[0008] The upper surface of the main body is provided with a plurality of strip-shaped grooves, one end of which is used to connect with the annular cavity on the burner, and the other end of which is connected to the outside of the main body;

[0009] The cover is placed on the main body to enclose each of the strip grooves to form a fire outlet channel;

[0010] The end of the strip groove away from the annular cavity forms a fire outlet.

[0011] In one possible implementation,

[0012] The main body includes an annular top wall, an outer annular wall, and an inner annular wall. The outer annular wall is connected to the outer edge of the top wall, and the inner annular wall is connected to the inner edge of the top wall.

[0013] The top wall, the outer ring wall, and the inner ring wall together enclose an air delivery cavity, which is used to connect to the ring cavity;

[0014] The strip-shaped groove is disposed on the upper surface of the top wall, and the cover is disposed on the top wall. The strip-shaped groove communicates with the air delivery chamber.

[0015] In one possible implementation, the strip groove extends radially along the top wall, with one end of the strip groove extending in the direction of extension communicating with the gas delivery chamber, and the other end of the strip groove extending in the direction of extension communicating with the side of the outer annular wall opposite to the gas delivery chamber, so as to form the flame outlet.

[0016] In one possible implementation, the top wall is provided with at least one through hole at the end of the strip groove facing the air delivery chamber, and the strip groove is connected to the air delivery chamber through the through hole.

[0017] In one possible implementation, the cover has at least one limiting portion;

[0018] At least one of the limiting portions abuts against the side of the inner annular wall opposite to the gas delivery chamber;

[0019] And / or, at least one of the limiting portions abuts against the side of the outer annular wall opposite to the gas delivery chamber.

[0020] In one possible implementation, the main body is provided with an ignition channel, one end of which is connected to the annular cavity, and the other end of which is open and faces the ignition area on the burner.

[0021] In one possible implementation, the cover is provided with at least one first ignition hole for facing the ignition area, and the body is provided with at least one second ignition hole for communicating with the annular cavity, wherein the first ignition hole communicates with the second ignition hole to form the ignition channel.

[0022] In one possible implementation, the main body has an ignition groove on the side facing the cover, the ignition groove is connected to the first ignition hole, and the second ignition hole is formed on the inner wall of the ignition groove.

[0023] In one possible implementation, the main body is provided with a plurality of flame outlet gaps, which are used to connect the annular cavity to the outside of the main body.

[0024] Secondly, this application provides a cooking appliance, including a mounting base and at least one combustion mechanism as described in the above embodiments, wherein each combustion mechanism is disposed on the mounting base;

[0025] The combustion mechanism includes a body and a flame cap as described in any of the above embodiments disposed on the body.

[0026] This application provides a burner cap and a cooking appliance. The burner cap consists of a main body and a cover. The upper surface of the main body has multiple strip-shaped grooves, one end of which communicates with an annular cavity on the burner, and the other end connects to the outside of the main body. The cover is placed on the main body to enclose the strip-shaped grooves into a flame outlet channel. A flame outlet hole is formed at the end of each strip-shaped groove furthest from the annular cavity. Therefore, during use, when combustion occurs, the gas enters from one end of the strip-shaped groove, flows through the flame outlet channel, and exits through the flame outlet hole. This increases the depth of the flame outlet hole, increasing the backfire limit and reducing the possibility of backfire during combustion, thus solving the problem of easy backfire during combustion in the prior art. Furthermore, the burner cap can be installed simply by placing the cover on the main body, making the installation process convenient. Simultaneously, since the flame outlet channel is located on the upper surface of the main body, the length of the flame outlet channel is limited only by the width of the main body, thereby increasing the preset range of the flame outlet channel length (i.e., the depth of the flame outlet hole) and relatively expanding the limit value of the flame outlet hole depth.

[0043] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application and how they solve the aforementioned technical problems will be clearly and completely described below with reference to specific embodiments and accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0045] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0046] In related technologies, burners typically have a copper core region and an outer ring region. The outer ring region includes an outer ring cavity and a flame cap covering the outer ring cavity, with several flame outlet slits on the flame cap. In use, the copper core region and the outer ring region are ignited, and the flame in the outer ring region is ejected outward from the flame outlet slits.

[0047] However, during the use of burners, because the burner cap is usually made of sheet metal, the wall thickness of the burner cap is relatively thin and the depth of the flame outlet gap is relatively shallow. This makes it easy for backfire to occur during the combustion process (backfire refers to the flame retreating into the interior of the burner or even into the gas pipeline. This process can easily lead to incomplete combustion of gas and the production of harmful gases), reducing the safety of use.

[0048] Therefore, this application provides a flame cap and cooking appliance, wherein the flame cap comprises a main body and a cover; the upper surface of the main body is provided with multiple strip-shaped grooves, one end of which communicates with the annular cavity on the burner, and the other end of which communicates with the outside of the main body; the cover is placed on the main body to enclose the strip-shaped grooves to form a flame outlet channel; the end of the strip-shaped groove away from the annular cavity forms a flame outlet hole. In use, the flame cap can be placed over the outer annular area of ​​the burner, so that the flame outlet channel communicates with the outer annular cavity. After ignition, the flame will be ejected from the flame outlet hole through the flame outlet channel; and during use, the flame outlet channel increases the depth of the flame outlet hole, increases the backfire limit, reduces the possibility of backfire during combustion, and solves the problem of easy backfire during combustion in the prior art.

[0049] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings and specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a flame cover, including a main body 100 and a cover 200;

[0051] The upper surface of the main body 100 is provided with a plurality of strip-shaped grooves. One end of the strip-shaped groove is used to connect with the annular cavity on the burner, and the other end of the strip-shaped groove is connected to the outside of the main body 100.

[0052] The cover 200 is placed on the main body 100 to enclose the strip grooves to form a fire outlet channel 300;

[0053] The end of the strip groove away from the annular cavity forms a fire outlet 310.

[0054] The main body 100 can be annular to cover the annular cavity on the burner more completely. Of course, the main body 100 can also be other shapes, and there are no restrictions on this.

[0055] The upper surface of the main body 100 is provided with multiple strip-shaped grooves. One end of each strip-shaped groove is connected to the annular cavity on the burner, and the other end is connected to the outside of the main body 100. The cover 200 is placed on the main body 100 to enclose each strip-shaped groove to form a flame outlet channel 300, and the end of each strip-shaped groove facing the outside of the main body 100 is a flame outlet hole 310.

[0056] During installation, the main body 100 is placed over the annular cavity of the burner, and then the cover 200 is placed over the main body 100, thus forming multiple flame outlet holes 310 and flame outlet channels 300 on the main body 100. During ignition, the gas entering the annular cavity passes through the flame outlet channels 300 and is then ejected from the flame outlet holes 310, subsequently contacting the outside air to form a flame. Furthermore, during combustion, the flame outlet channels 300 increase the depth of the flame outlet holes 310, increasing the flashback limit and reducing the possibility of flashback during combustion, thus solving the problem of flashback easily occurring during combustion in existing technologies. In addition, the burner cap can be installed simply by placing the cover 200 over the main body 100, making the installation process relatively convenient.

[0057] Meanwhile, since the flame outlet channel 300 is located on the upper surface of the main body 100, the length of the flame outlet channel 300 is limited only by the width of the main body 100, which allows for a wider preset range of the length of the flame outlet channel 300 (i.e. the depth of the flame outlet hole 310), thereby relatively expanding the limit value of the depth of the flame outlet hole 310.

[0058] like Figure 2 As shown, in some embodiments, the main body 100 includes an annular top wall 110, an outer annular wall 120, and an inner annular wall 130. The outer annular wall 120 is connected to the outer edge of the top wall 110, and the inner annular wall 130 is connected to the inner edge of the top wall 110. The top wall 110, the outer annular wall 120, and the inner annular wall 130 together enclose an air delivery cavity 140, which is used to connect to the annular cavity. A strip-shaped groove is provided on the upper surface of the top wall 110, and a cover 200 is provided on the top wall 110. The strip-shaped groove connects to the air delivery cavity 140.

[0059] Specifically, the top wall 110 is annular and horizontally positioned. The outer annular wall 120 and the inner annular wall 130 are both located below the top wall 110. The outer annular wall 120 is connected to the outer edge of the top wall 110, and the inner annular wall 130 is connected to the inner edge of the top wall 110. This allows the top wall 110, the outer annular wall 120, and the inner annular wall 130 to together enclose an annular air delivery cavity 140, and the lower end of the air delivery cavity 140 is an open structure.

[0060] In actual implementation, the top wall 110, the outer ring wall 120, and the inner ring wall 130 can be integrally formed, or the outer ring wall 120 and the inner ring wall 130 can be welded or connected to the top wall 110 in other ways, without any restrictions.

[0061] It is understood that the cover 200 covers the top wall 110, and the flame outlet channel 300 is located between the upper surface of the top wall 110 and the cover 200. Furthermore, the flame outlet channel 300 is connected to the gas supply chamber 140.

[0062] When the main body 100 is placed over the annular cavity of the burner, the gas delivery chamber 140 can be connected to the annular cavity through the opening below, so that the gas passes through the flame outlet 300 and is output from the flame outlet 310 to form a flame.

[0063] like Figure 2 and Figure 3 As shown, in some embodiments, the strip groove extends radially along the top wall 110, one end of the strip groove extending in the direction of extension is connected to the gas delivery chamber 140, and the other end of the strip groove extending in the direction of extension is connected to the side of the outer ring wall 120 away from the gas delivery chamber 140 to form a flame outlet 310.

[0064] Specifically, the upper surface of the top wall 110 is recessed downwards to form multiple strip-shaped grooves, which are distributed circumferentially along the top wall 110 and extend radially along the top wall 110. One end of the extending direction of the strip-shaped groove is connected to the gas supply chamber 140, thereby forming a flame outlet channel 300; the other end of the extending direction of the strip-shaped groove is connected to the side of the outer ring wall 120 opposite to the gas supply chamber 140 to form a flame outlet 310, which facilitates the flame to be sprayed outwards.

[0065] Furthermore, the top wall 110 is provided with at least one through hole 320 at the end of the strip groove facing the air delivery chamber 140, and the strip groove is connected to the air delivery chamber 140 through the through hole 320.

[0066] In this embodiment, two through holes 320 are provided at one end of the strip groove facing the gas delivery chamber 140. One through hole 320 is located at the bottom of the strip groove, and the other through hole 320 is located on the side of the strip groove, so that the strip groove is connected to the gas delivery chamber 140 through the two through holes 320, so that the gas can flow from the gas delivery chamber 140 into the strip groove, while ensuring the gas flow rate.

[0067] In other embodiments, the strip groove can also be provided on the side of the cover 200 facing the top wall 110, so that when the cover 200 is placed on the top wall 110, multiple fire outlet channels 300 are also constructed between the top wall 110 and the cover 200.

[0068] After the cover 200 is installed, to ensure its stability, such as... Figure 2 As shown, the cover 200 can be further configured to have at least one limiting portion 210;

[0069] At least one limiting part 210 abuts against the side of the inner annular wall 130 opposite to the air delivery chamber 140;

[0070] And / or, at least one limiting portion 210 abuts against the side of the outer annular wall 120 opposite to the gas delivery chamber 140.

[0071] In this embodiment, the cover 200 is provided with two limiting portions 210. The limiting portions 210 can be configured as a ring structure and extend vertically. The limiting portions 210 are coaxial with the cover 200. One limiting portion 210 is connected to the inner edge of the cover 200, and the other limiting portion 210 is connected to the outer edge of the cover 200.

[0072] When the cover 200 covers the top wall 110, the limiting part 210 on the inner edge of the cover 200 is inserted into the inner side of the main body 100, so that the limiting part 210 abuts against the side of the inner ring wall 130 away from the air supply chamber 140. The limiting part 210 on the outer edge of the cover 200 is sleeved on the outer side of the main body 100, thereby positioning the cover 200 through each limiting part 210, improving the stability of the cover 200 after installation, and reducing the possibility of the cover 200 slipping off the top wall 110.

[0073] In actual implementation, the limiting part 210 can be integrally formed with the cover 200, or the limiting part 210 can be connected to the cover 200 by welding or other means, and there is no restriction on this.

[0074] In other embodiments, the limiting portion 210 may be set to other quantities, or the limiting portion 210 may be provided only on the inner edge / outer edge of the cover 200, or the limiting portion 210 may be set as a plurality of spaced limiting protrusions.

[0075] like Figure 2 and Figure 3 As shown, in some embodiments, the main body 100 is provided with a plurality of flame outlet gaps 500, which are used to connect the annular cavity to the outside of the main body 100.

[0076] In this embodiment, multiple flame outlet gaps 500 are all opened on the outer ring wall 120 and are evenly distributed around the outer ring wall 120, so that the flame outlet gaps 500 connect the gas delivery chamber 140 with the outside of the main body 100.

[0077] In other embodiments, the flame outlet gap 500 may be formed on the inner ring wall 130 or the top wall 110, and the shape of the flame outlet gap 500 is not limited.

[0078] When in use, some of the gas will be output from the flame outlet 500, thus forming a flame. Combined with the flame formed by the flame outlet 310, it can ensure the overall stability of the flame on the burner cap, thereby ensuring the stability of the cookware during subsequent heating.

[0079] In practical implementation, for example, an annular groove can be formed on the side of the outer annular wall 120 opposite to the gas supply chamber 140, and the annular groove extends circumferentially along the outer annular wall 120. In this case, multiple flame outlet gaps 500 are formed on the outer annular wall 120 and located at the bottom of the annular groove. Thus, the flame stability at the flame outlet gaps 500 is further ensured by the annular groove.

[0080] Typically, a burner has a copper core region and an outer ring region. During ignition, the copper core region is ignited first, and then the flame in the copper core region ignites the outer ring region. For example, when installing the burner cap, it is often placed in the outer ring region, that is, the burner cap covers the outer ring cavity on the burner.

[0081] At this time, in order to facilitate the transmission of fire from the copper core area to the outer ring area, such as Figure 1 As shown, in some embodiments, the main body 100 is provided with an ignition channel 400, one end of which is used to communicate with the annular cavity, and the other end of which is open and faces the ignition area on the burner.

[0082] It should be noted that the copper core area is the ignition area. When the main body 100 covers the outer annular cavity of the burner, one end of the ignition channel 400 is connected to the gas supply chamber 140 inside the main body 100, and the other end of the ignition channel 400 has an open structure, with the opening facing the copper core area inside the main body 100.

[0083] When in use, after the copper core area is ignited, some of the gas in the outer ring cavity will be sprayed towards the copper core area through the ignition channel 400, which facilitates the transfer of the fire in the copper core area to the outer ring area, thereby enabling the outer ring area to be ignited more efficiently.

[0084] In actual installation, the burner cap can also be placed over other annular cavities on the burner. Furthermore, the orientation of the ignition channel 400 opening can be reasonably arranged according to the location of the actual ignition area, and there are no restrictions on this.

[0085] like Figure 4and Figure 5 As shown, the cover 200 is further provided with at least one first ignition hole 220 for facing the ignition area, and the main body 100 is provided with at least one second ignition hole 150 for communicating with the annular cavity. The first ignition hole 220 communicates with the second ignition hole 150 to form an ignition channel 400.

[0086] In this embodiment, the first ignition hole 220 is formed on the limiting part 210, and the first ignition hole 220 penetrates the limiting part 210, so that when the entire flame cap covers the outer annular cavity of the burner, the opening of the first ignition hole 220 faces the copper core area inside the flame cap. Multiple first ignition holes 220 can be provided, for example, two, three, or other numbers, and multiple first ignition holes 220 are concentrated at the same end of the limiting part 210.

[0087] The second ignition hole 150 is formed on the main body 100 and is connected to the gas delivery chamber 140. Specifically, the second ignition hole 150 can be formed on the top wall 110 or the inner ring wall 130, so that the first ignition hole 220 is connected to the second ignition hole 150, and no other restrictions are imposed.

[0088] When gas is introduced into the annular cavity, the gas will pass through the second ignition hole 150 and the first ignition hole 220 in sequence before being output towards the copper core area, thereby facilitating the transfer of the flame from the copper core area to the outer annular area.

[0089] like Figure 4 and Figure 5 As shown, in some embodiments, the main body 100 is provided with an ignition groove 160 on the side facing the cover 200, the ignition groove 160 is connected to the first ignition hole 220, and the second ignition hole 150 is opened on the inner wall of the ignition groove 160.

[0090] It should be noted that, in this embodiment, an ignition groove 160 is formed on the upper surface of the top wall 110. The ignition groove 160 is strip-shaped and extends radially along the top wall 110. One end of the ignition groove 160 facing the central axis of the top wall 110 is connected to each of the first ignition holes 220, and the other end of the ignition groove 160 away from the central axis of the top wall 110 is connected to the outer surface of the outer ring wall 120. A second ignition hole 150 is formed on the top wall 110 and is located on the inner wall of the ignition groove 160, so that the ignition groove 160 is connected to the gas delivery chamber 140 through the second ignition hole 150. Multiple second ignition holes 150 can be provided, such as two, three, or other numbers.

[0091] Thus, the first ignition hole 220, the second ignition hole 150, and the ignition groove 160 together form the ignition channel 400.

[0092] In operation, the gas flows sequentially through the second ignition hole 150, the ignition groove 160, and the first ignition hole 220 before being output towards the copper core area, facilitating the transfer of flame from the copper core area to the outer ring area. The ignition groove 160 also ensures rapid and stable gas output from the first ignition hole 220, contributing to improved flame transmission. Furthermore, it effectively reduces the probability of flame detachment under cold conditions and improves the effect of flashback under hot conditions.

[0093] In summary, this application provides a flame cap that, during use, allows the combustion gas in the input annular cavity to pass through the flame outlet channel 300 and then be ejected from the flame outlet 310, subsequently contacting the outside air to form a flame. Furthermore, during combustion, the increased depth of the flame outlet 310 through the flame outlet channel 300 increases the flashback limit, reducing the likelihood of flashback during combustion and solving the problem of flashback easily occurring during combustion in the prior art.

[0094] This application also provides a cooking appliance, which can be a gas stove, integrated stove, or other device used to supply fire for the cooking process.

[0095] like Figure 6 and Figure 7 As shown, in some embodiments, the cooking appliance includes a mounting base and at least one combustion mechanism, each combustion mechanism being disposed on the mounting base;

[0096] The combustion mechanism includes a body 10 and a flame cap as described in any of the above embodiments disposed on the body 10.

[0097] There are no restrictions on the structure of the mounting base or the number of combustion mechanisms, and the mounting base is not shown here.

[0098] For example, the mounting base may have multiple mounting cavities with upper openings, and during installation, each combustion mechanism can be installed in its respective mounting cavity.

[0099] The combustion mechanism includes a burner head 11, a thermocouple 12, an electrode needle 13, and an inner ring cover 14. The burner head 11 has a first annular cavity 15 and a second annular cavity 16, with the first annular cavity 15 located inside the second annular cavity 16. The inner ring cover 14 covers the first annular cavity 15, and the burner cover covers the second annular cavity 16.

[0100] The specific structure of the flame cap has been described in detail in the above embodiments and will not be repeated here.

[0101] Thermocouple 12 and electrode needle 13 are both located between the first annular cavity 15 and the second annular cavity 16. Thermocouple 12 is used to detect the flame to ensure safe use; electrode needle 13 is used to ignite the area of ​​the first annular cavity 15. In use, the area of ​​the first annular cavity 15 is ignited through electrode needle 13, and then the flame is transmitted to the area of ​​the second annular cavity 16.

[0102] In other embodiments, the burner cap may also cover the first annular cavity 15; and it may also cover other annular cavities depending on the annular cavity structure on the actual burner head 11, without limitation.

[0103] In summary, the embodiments of this application provide a cooking appliance that, during combustion, increases the depth of the flame outlet 310 through the flame outlet channel 300, increases the backfire limit, reduces the possibility of backfire during combustion, and solves the problem of easy backfire during combustion in the prior art.

However, it is readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit them.
