Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a fire distributor and a burner. Background Art

[0002] At present, household gas stoves generally have a burner, which usually includes a fire distributor, an outer ring fire cover, and an inner ring fire cover arranged in the center of the outer ring fire cover. The outer ring fire cover and the inner ring fire cover are buckled on the fire distributor, and the outer ring fire cover and the fire distributor are enclosed to form an outer ring gas mixing chamber, and the inner ring fire cover and the fire distributor are enclosed to form an inner ring gas mixing chamber. The gas mixture enters the inner ring gas mixing chamber and the outer ring gas mixing chamber, flows out from the fire outlet holes of the inner ring fire cover and the outer ring fire cover, and burns.

[0003] In some burners, a smaller fire outlet structure is provided than the inner ring fire cover. Specifically, the ignition divider is formed with three cavities from the inside to the outside. The central cavity is cylindrical and located at the center, the inner ring cavity is in a circular shape and located at the periphery of the central cavity and is spaced a certain distance from the central cavity, and the outer ring cavity is located at the periphery of the inner ring cavity and is spaced a certain distance from the inner ring cavity. The burner includes a central fire cover, which is buckled on the central cavity, and the central fire cover and the ignition divider are enclosed to form a central air mixing chamber. The central air mixing chamber, the inner ring air mixing chamber and the outer ring air mixing chamber are independent of each other to meet more diverse power requirements.

[0004] The structure of the fire divider arranged in this way is too complicated and the production cost is high. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a fire divider is provided. The fire divider includes a middle body, the middle body has a bottom wall and a side wall connected to the bottom wall, the bottom wall and the side wall enclose a cavity opening upward, a partition is arranged in the cavity to divide the cavity into a first cavity and a second cavity, a first ejection channel and a second ejection channel are arranged on the bottom wall, the first ejection channel is connected to the first cavity, and the second ejection channel is connected to the second cavity.

[0006] The fire divider provided by the present application divides the middle body into a first cavity and a second cavity by setting a separator, and the structural setting is simpler, and the production difficulty and cost are lower. The first cavity and the second cavity separated by the separator are adjacent to each other, which makes fuller use of the internal space of the middle body, and the structure is more compact, which can provide more space for the arrangement of other structural parts in the fire divider. The first cavity and the first ejection channel form an air path, and the second cavity and the second ejection channel form another air path. When applied to a burner, the two air paths can be used to supply air to the two ignition structures respectively, which can ensure that the two ignition structures are independent of each other, and the combustion effects do not affect each other, that is, better meet the combustion requirements of different powers.

[0007] Exemplarily, the side wall includes a first portion and a second portion connected end to end, the separator is connected to the connection between the first portion and the second portion, the first portion, the separator and a portion of the bottom wall enclose a first cavity, and the second portion, the separator and a portion of the bottom wall enclose a second cavity. In this way, the structure of the separator disposed in the middle body is simpler, and less space in the middle body can be occupied, so that the volume of the first cavity and the second cavity can be as large as possible.

[0008] Exemplarily, the first cavity extends along the first direction, the first ejection channel extends along the second direction and is connected to the first cavity, and the second direction and the first direction meet the perpendicular condition. In this way, the first ejection channel can have a certain barrier effect on the overflowing liquid, oil, etc., so that the overflowing liquid, oil, etc. are less likely to contact the first ejection nozzle corresponding to the first ejection channel, thereby ensuring the working stability of the first ejection channel.

[0009] Exemplarily, the first ejection channel includes an ejection section and a connecting section, the connecting section is connected between the first cavity and the ejection section, and the cross-sectional area of ​​the ejection section gradually decreases along the second direction. In this way, the gas entering the ejection section can better eject the surrounding air, so that the air ratio in the gas mixture in the first cavity is higher, thereby ensuring combustion efficiency.

[0010] Exemplarily, the first cavity extends along the first direction, a first ejection hole is provided on the bottom wall, and the first ejection channel extends from the first ejection hole along the first direction to communicate with the second cavity. In this way, the flow process of the gas mixture in the first ejection channel and the first cavity does not involve a change in direction, and the flow is smoother. In addition, the first ejection channel and the first cavity both extend in the first direction, which can reduce the space they occupy in the second direction. Correspondingly, more sufficient space is provided for other structural parts of the middle body in the second direction. For example, the cavity volume of the middle body can be correspondingly larger, and the structural setting is more reasonable.

[0011] Exemplarily, the cross-sectional area of ​​the first injection channel gradually decreases along the first direction. In this way, the gas entering the first injection channel can better inject the surrounding air, so that the air ratio in the gas mixture in the first chamber is higher, thereby ensuring combustion efficiency.

[0012] Exemplarily, the projection of the first cavity toward the bottom wall falls into the first ejection channel. In this way, the process of the gas mixture in the first ejection channel flowing into the first cavity is smoother, and the combustion process is more stable.

[0013] Exemplarily, the volume of the first chamber is smaller than that of the second chamber. The volume of the first chamber is smaller than that of the second chamber. The first chamber can be used to meet the demand for extremely low power, and the second chamber can be used to meet the demand for relatively large power. The two are independent and the combustion effects do not affect each other, which can better ensure the stability of combustion under two different powers.

[0014] Exemplarily, an outer ring body is disposed on the periphery of the middle body, the outer ring body has an outer ring cavity opening upward, an outer ring ejection channel is disposed at the bottom of the outer ring body, and the outer ring ejection channel is connected to the outer ring cavity. In this way, the outer ring body is located on the periphery of the middle body, and the outer ring cavity can be larger to meet the needs of more diverse combustion power.

[0015] According to another aspect of the utility model, a burner is provided, which includes a fire cover and any one of the above-mentioned fire dividers, wherein a third cavity and a fourth cavity spaced apart from each other are formed in the fire cover, the fire cover is buckled on the middle body, the first cavity and the third cavity are matched to form a first gas mixing chamber, and the second cavity and the fourth cavity are matched to form a second gas mixing chamber.

[0016] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section. The utility model content section is not intended to limit the key features and essential technical features of the technical solution claimed for protection, nor is it intended to determine the scope of protection of the technical solution claimed for protection.

[0029] In the following description, a large number of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only illustrates preferred embodiments of the present invention, and the present invention can be implemented without one or more of such details. In addition, in order to avoid confusion with the present invention, some technical features known in the art are not described in detail.

[0030] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0031] The utility model provides a flame divider in the embodiment, which can be applied to any type of burner. Figure 1 , 2, 3 and 5, the fire divider 120 may include a middle body 1210, and the middle body 1210 may have a bottom wall 1211 and a side wall 1212 connected to the bottom wall 1211. The bottom wall 1211 and the side wall 1212 enclose a cavity 1213 with an opening upward. A partition 1220 is provided in the cavity 1213 and divides the cavity 1213 into a first cavity 1213a and a second cavity 1213b. The first cavity 1213a and the second cavity 1213b are separated by the partition 1220, that is, the first cavity 1213a and the second cavity 1213b are adjacent to each other and there is a partition 1220 between the two. The positions of the first cavity 1213a and the second cavity 1213b can be of any shape, and can be as shown in the embodiment shown in the figure, the first cavity 1213a is cylindrical, and the second cavity 1213b is irregular with a cylindrical notch. Alternatively, the first cavity and the second cavity may be arranged in any other way according to the use requirements, which depends on the structural arrangement of the partition 1220. The partition 1220 may be connected to the side wall 1212 at both ends, or the partition 1220 may be connected end to end, for example, in a cylindrical arrangement, or the first partition 1220 may be arranged in any direction or trajectory according to the use requirements, so as to ensure that the first cavity 1213a and the second cavity 1213b are separated from each other. The bottom wall 1211 may be provided with a first ejection channel 1230 and a second ejection channel 1240, the first ejection channel 1230 may be connected to the first cavity 1213a, and the second ejection channel 1240 may be connected to the second cavity 1213b. Among them, the first ejection channel 1230 may extend along any direction or trajectory and be connected to the first cavity 1213a, and the second ejection channel 1240 may extend along any direction or trajectory and be connected to the second cavity 1213b. The directions or trajectories in which the first ejection channel 1230 and the second ejection channel 1240 extend may be the same or different. Specifically, the first ejection channel 1230 may be formed on the bottom wall 1211, that is, the bottom wall 1211 itself may form the first ejection channel 1230 (e.g., Figure 5 Alternatively, the bottom wall 1211 may form a portion of the channel wall of the first ejection channel 1230 (eg, Figure 3). Alternatively, in an embodiment not shown, the first injection channel 1230 can be independently provided, and a connecting port can be provided on the bottom wall 1211, and the first injection channel 1230 is connected to the first cavity 1213a through the connecting port. There are two gas paths in the ignition divider 120, gas path one: gas and air enter the first injection channel 1230, mix in the first injection channel 1230 and enter the first cavity 1213a; gas path two: gas and air enter the second injection channel 1240, mix in the second injection channel 1240 and enter the second cavity 1213b, and the two gas paths are independently provided. When applied to the burner 10, the two gas paths can be used to supply gas to two ignition structures, such as an inner ring ignition structure and a limit ignition structure with a smaller ignition than the inner ring.

[0032] Compared with the solution in the prior art that the inner ring air cavity is arranged on the periphery of the central air cavity and is arranged at a certain distance, the ignition divider 120 provided in the present application, through the setting of the partition 1220, separates the middle body 1210 into the first cavity 1213a and the second cavity 1213b, and the structural setting is simpler, and the production difficulty and cost are lower. The first cavity 1213a and the second cavity 1213b separated by the partition 1220 are adjacent to each other, and the internal space of the middle body 1210 is more fully utilized. The structure is more compact, and more space can be provided for the arrangement of other structural parts in the ignition divider 120. The first cavity 1213a and the first ejection channel 1230 form a gas path, and the second cavity 1213b and the second ejection channel 1240 form another gas path. When applied to the burner 10, the two gas paths can be used to supply gas to the two ignition structures respectively, which can ensure that the two ignition structures are independent of each other, and the combustion effects do not affect each other, that is, better meet the combustion requirements of different powers.

[0033] For example, in conjunction with reference Figure 1 and 2, the side wall 1212 may include a first portion 1212a and a second portion 1212b connected end to end, a separator 1220 is connected to the connection between the first portion 1212a and the second portion 1212b, the first portion 1212a, the separator 1220 and a portion of the bottom wall 1211 enclose a first cavity 1213a, and the second portion 1212b, the separator 1220 and a portion of the bottom wall 1211 enclose a second cavity 1213b. The separator 1220 may be only a partition wall, the two ends of which are connected to the side wall 1212, and the side wall 1212 itself constitutes a part of the structure enclosing the first cavity 1213a and the second cavity 1213b. In this way, the structure of the separator 1220 disposed in the middle body 1210 is simpler, and less space in the middle body 1210 can be occupied, so that the volume of the first cavity 1213a and the second cavity 1213b can be as large as possible. In an embodiment not shown, the partition may be in the shape of a ring, the partition rib and a portion of the bottom wall enclose a first cavity, and the partition, the side wall and a portion of the bottom wall enclose a second cavity.

[0034] For example, refer to Figure 3 and 8 , the first cavity 1213a may extend along the first direction XX', the first injection channel 1230 may extend along the second direction YY' and communicate with the first cavity 1213a, and the second direction YY' may meet the vertical condition with the first direction XX'. Accordingly, the bottom of the middle body 1210 may be provided with a first injection hole 1214. Specifically, the first injection hole 1214 may be located in the lateral direction of the bottom of the middle body 1210. In the burner 10 provided with the ignition divider 120, the first injection nozzle corresponding to the first injection channel 1230 is oriented in the second direction YY'. The gas enters the first injection channel 1230 along the second direction YY', and then enters the first cavity 1213a along the first direction XX'. In this way, the first injection channel 1230 can provide a certain barrier to overflowing liquid, oil stains, etc., making it less likely for overflowing liquid, oil stains, etc. to contact the first injection nozzle corresponding to the first injection channel 1230, thereby ensuring the stability of the operation of the first injection channel 1230.

[0035] For example, continue to refer to Figure 3 and 8 , the first ejection channel 1230 may include an ejection section 1231 and a connecting section 1232. The connecting section 1232 may be connected between the first cavity 1213a and the ejection section 1231, and the cross-sectional area of ​​the ejection section 1231 gradually decreases along the second direction Y-Y'. In this way, the gas entering the ejection section 1231 may better eject the surrounding air, so that the air ratio in the gas mixture in the first cavity 1213a is higher, thereby ensuring the combustion efficiency.

[0036] For example, refer to Figure 5 and9 , the first cavity 1213a may extend along the first direction XX', a first ejection hole 1214 may be provided on the bottom wall 1211, and the first ejection channel 1230 extends from the first ejection hole 1214 along the first direction XX' to communicate with the second cavity 1213b. That is to say, the first ejection channel 1230 and the first cavity 1213a have the same extension direction. In the burner 10 provided with the ignition divider 120, the first ejection nozzle corresponding to the first ejection channel 1230 is oriented in the first direction XX'. The gas enters the first ejection channel 1230 along the first direction XX', and then continues to enter the first cavity 1213a along the first direction XX'. With this arrangement, the flow process of the gas mixture in the first ejection channel 1230 and the first cavity 1213a does not involve a change in direction, and the flow is smoother. Moreover, the first ejection channel 1230 and the first cavity 1213a both extend in the first direction XX', which can reduce the space they occupy in the second direction YY'. Correspondingly, more sufficient space is provided for other structural parts of the middle body 1210 in the second direction YY', for example, the volume of the cavity 1213 of the middle body 1210 can be correspondingly larger, and the structural setting is more reasonable. Exemplarily, in order to ensure the ejection effect, the thickness of the bottom wall 1211 corresponding to the first ejection channel 1230 can be appropriately increased so that the length of the first ejection channel 1230 is large enough.

[0037] For example, continue to refer to Figure 5 and 9 The cross-sectional area of ​​the first ejection channel 1230 can be gradually reduced along the first direction XX'. In this way, the gas entering the first ejection channel 1230 can better eject the surrounding air, so that the air ratio in the gas mixture in the first chamber 1213a is higher, ensuring the combustion efficiency.

[0038] For example, continue to refer to Figure 5 and 9 , the projection of the first cavity 1213a toward the bottom wall 1211 falls into the first ejection channel 1230. In this way, the process of the gas mixture in the first ejection channel 1230 flowing into the first cavity 1213a is smoother, and the combustion process is more stable. In the embodiment where the cross-sectional area of ​​the first ejection channel 1230 gradually decreases along the first direction, the projection of the first cavity 1213a toward the bottom wall 1211 can coincide with the projection of one end of the first ejection channel 1230 close to the first cavity 1213a on the bottom wall 1211.

[0039] For example, in conjunction with reference Figure 8-10, the volume of the first cavity 1213a may be smaller than the volume of the second cavity 1213b. In the burner 10 provided with the ignition divider 120, the fire cover 110 may be provided with a first fire outlet 1122 and a second fire outlet 1112. The first fire outlet 1122 is communicated with the first cavity 1213a, and the second fire outlet 1112 is communicated with the second cavity 1213b. Since the first cavity 1213a and the second cavity 1213b are independent of each other, that is, different power requirements of the burner 10 can be achieved by reasonably setting the first cavity 1213a and the second cavity 1213b, respectively. The volume of the first cavity 1213a is smaller than that of the second cavity 1213b. The first cavity 1213a can be used to meet the demand for extremely low power, and the second cavity 1213b can be used to meet the demand for relatively large power. The two are independent, and the combustion effects do not affect each other, which can better ensure the stability of combustion under two different powers.

[0040] For example, in conjunction with reference Figure 1 , 2 , 4 and 6, an outer ring body 1250 may be provided on the periphery of the middle body 1210. The outer ring body 1250 may have an outer ring cavity 1251 that opens upward, and an outer ring introduction channel 1280 is provided at the bottom of the outer ring body 1250, and the outer ring introduction channel 1280 is connected to the outer ring cavity 1251. Specifically, the outer ring introduction channel 1280 may be extended in a predetermined plane perpendicular to the first direction. In the burner 10 provided with the ignition distributor 120, an outer ring fire cover 140 may be provided on the outer ring body 1250, and the gas passes through the outer ring introduction channel 1280, mixes with the air and enters the outer ring cavity 1251, and flows out and burns through the third fire outlet 1420 on the outer ring fire cover 140. In this way, the outer ring body 1250 is located on the periphery of the middle body 1210, and the outer ring cavity 1251 can be larger to meet the needs of more diverse combustion power.

[0041] According to another aspect of the utility model, a burner 10 is also provided. The burner 10 may include a fire cover 110 and any one of the above-mentioned ignition dividers 120. A third cavity 1121 and a fourth cavity 1111 spaced apart from each other are formed in the fire cover 110, and the fire cover 110 is buckled on the middle body 1210, and the first cavity 1213a and the third cavity 1121 are matched to form a first gas mixing chamber, and the second cavity 1213b and the fourth cavity 1111 are matched to form a second gas mixing chamber. Since the ignition divider 120 adopts the technical solution of any one of the above-mentioned embodiments, the burner 10 at least has the beneficial effects brought by the technical solution of the above-mentioned embodiments, which will not be repeated here one by one.

[0042] It is understandable that, since the first cavity 1213a and the second cavity 1213b are separated and formed by the partition 1220, the structural arrangement is more compact. Correspondingly, two independent gas mixing chambers can be formed by only buckling a fire cover 110 on the middle body 1210. The fire cover 110 can be understood as an inner ring fire cover 110, and the size of the fire cover 110 can also be similar to that of a common inner ring fire cover. In other words, compared with the prior art solution having a central gas mixing chamber, an inner ring gas mixing chamber and an outer ring gas mixing chamber, the overall size of the burner 10 in the present application can be smaller, and can be closer to or even consistent with the size of a common burner (i.e., a burner having only an inner ring gas mixing chamber and an outer ring gas mixing chamber). In addition, the burner 10 may also include an outer ring fire cover 140, a burner head seat 130, a thermocouple 1510 and an ignition needle 1520. The outer ring fire cover 140, the burner head seat 130, the thermocouple 1510 and the ignition needle 1520 may have various existing or future possible structures, which do not constitute a limitation on the protection scope of the present utility model.

[0043] Exemplarily, the thermocouple 1510 may be disposed on a side close to the first cavity 1213a, so that the ignition of the first ignition hole 1122 connected to the first cavity 1213a can be better sensed by the thermocouple 1510, and the monitoring of the combustion condition of the burner 10 is more accurate. Correspondingly, a thermocouple mounting hole 1260 and / or an ignition needle mounting hole 1270 may be disposed on the burner head seat 130. The thermocouple mounting hole 1260 is located between the first cavity 1213a and the outer ring body 1250, and the ignition needle mounting hole 1270 is located between the second cavity 1213b and the outer ring body 1250.
