Description

Technical Field

[0001] The utility model relates to the technical field of kitchenware, in particular to a fire cover component and a gas stove. Background Art

[0002] A gas stove usually includes a stove head and a fire cover assembly. The fire cover assembly includes a fire divider seat and a fire cover arranged on the fire divider seat. The fire divider seat is provided with an air inlet, and the fire cover is provided with fire outlet holes. Since the air inlet is arranged on one side of the fire divider seat, the fire outlet holes on the fire cover are located at different distances from the air inlet. The fire outlet holes close to the air inlet will have an air outlet speed significantly faster than that of the fire outlet holes far away from the air inlet due to the direct airflow. As a result, the fire outlet holes close to the air inlet are particularly prone to flame separation, while the flames are smaller at the fire outlet holes far away from the air inlet, resulting in uneven flames. Utility Model Content

[0003] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a fire cover assembly is provided, and the technical solution is as follows.

[0004] The fire cover assembly includes a fire dividing seat, a fire cover and a guide plate, wherein the fire dividing seat is provided with an air inlet; the fire cover is arranged on the fire dividing seat and encloses an air mixing chamber with the fire dividing seat; the guide plate is arranged in the air mixing chamber and connected to the fire cover; wherein the fire cover has a fire outlet wall with a fire outlet hole, the guide plate is located between the air inlet and the fire outlet wall, and in the radial direction of the fire cover, the air mixing chamber is divided into a first part and a second part by the guide plate, the second part is closer to the fire outlet wall than the first part, and a gap connecting the first part and the second part is formed between the bottom end of the guide plate and the fire dividing seat.

[0005] When the fire cover assembly of the utility model is in use, gas enters the first part from the air inlet, a small part of the gas is blocked by the guide plate, and flows from the gap formed by the bottom end of the guide plate and the fire distributor seat to the second part, and then flows to the fire outlet holes, thereby preventing the gas from directly flowing out from the fire outlet holes close to the air inlet, and further preventing the fire outlet holes close to the air inlet from having flame separation; most of the gas is guided by the guide plate to the fire outlet holes far away from the air inlet; thereby, the gas volume of the fire outlet holes near the air inlet and the gas volume of the fire outlet holes far away from the air inlet are guaranteed at the same time, so that the gas outlet of the entire circle of fire cover fire outlet holes is uniform, so that the flames of each fire outlet are relatively uniform, and the flame separation at the fire outlet holes near the air inlet is avoided.

[0006] Exemplarily, the gap is 2 mm to 5 mm. This arrangement facilitates the gas to flow from the first part to the second part through the gap, and the gap accelerates the gas to quickly form a vortex in the second part, thereby improving the mixing effect of the gas.

[0007] For example, the guide plate is provided with a plurality of gas supplement holes connecting the first part and the second part, and the plurality of gas supplement holes are arranged at intervals. In this way, the gas can flow to the second part through the gas supplement holes, thereby avoiding the situation where insufficient gas flows to the second part through the gap.

[0008] For example, the gas supply holes and the fire outlet holes are arranged alternately, so as to enhance the gas mixing effect and improve the combustion efficiency.

[0009] For example, the center line of the adjacent gas supply holes and the center line of the fire outlet hole have an angle β, and the angle β is 0° to 2°. When the angle is within this range, it is convenient for gas to flow to the fire outlet hole through the gas supply holes, thereby effectively supplying gas.

[0010] For example, in the circumferential direction of the fire cover, the guide plate is arc-shaped. In this way, when the guide plate is arc-shaped, it has a better guiding effect, so that the gas outlet of the fire outlet holes of the whole circle of the fire cover is uniform, so that the flames of each fire outlet hole are relatively uniform.

[0011] Exemplarily, the guide plate is in an arc shape, and has a central angle α, which is 100° to 150°. When the central angle of the guide plate is within this range, the guide plate has a better guide effect, and avoids the guide plate having a smaller central angle, which weakens the guide effect, and avoids the guide plate having a larger central angle, which results in a smaller flame from a partially blocked fire outlet.

[0012] For example, the center of the circle to which the guide plate corresponds is concentric with the center of the fire distributor and the center of the fire cover. With such a configuration, the guide plate has a better guiding effect, so that the gas outlet of the fire outlet holes of the entire circle of the fire cover is uniform, thereby making the flames of each fire outlet hole relatively uniform.

[0013] Exemplarily, the guide plate includes at least an arc segment, and the center of the circle corresponding to the arc segment is concentric with the center of the fire distributor and the center of the fire cover. In this way, the arc segment of the guide plate has a good guiding effect, so that the gas outlet of the fire outlet holes of the whole circle of the fire cover is uniform, so that the flames of each fire outlet hole are relatively uniform.

[0014] For example, in a direction parallel to the central axis of the fire cover, the guide plate is arc-shaped, and the tangent of the guide plate forms an angle γ with the fire outlet wall, and the angle γ is 0° to 10°. This arrangement can effectively guide the gas, so that the gas outlet of the entire circle of fire cover outlet holes is uniform, so that the flames of each outlet hole are relatively uniform, and the mixing effect of the gas can be enhanced, thereby avoiding the situation where the outlet holes close to the air inlet have flame separation.

[0015] Exemplarily, there is a distance H between the guide plate and the fire outlet wall, and the distance H is 3 mm to 10 mm. Within this distance range, the guide plate has a better guide effect, and avoids the distance between the guide plate and the fire outlet wall being too large, thereby weakening the guide effect of the guide plate, and avoids the distance between the guide plate and the fire outlet wall being too small, thereby causing flame separation.

[0016] Exemplarily, the fire outlet wall has a first end and a second end, the first end is closer to the fire distributor seat than the second end, the fire cover also has a first wall, the first wall extends from the first end toward a direction away from the guide plate and away from the second end, and the first wall and the fire distributor seat enclose a gas mixing space that communicates with the second part, and the gas mixing space is connected to the air inlet through the gap. Such a configuration facilitates gas to enter the gas mixing space from the gap to form a cyclone, enhances the mixing effect of the gas, and thus avoids the situation of flame separation.

[0017] Exemplarily, the fire cover further comprises a second wall, the second wall is connected to the second end, the guide plate comprises a connecting end arranged opposite to the bottom end, and the connecting end is connected to the second wall. Such arrangement prevents gas from flowing into the fire outlet from between the guide plate and the second wall, thereby preventing the fire outlet near the air inlet from having a flame separation phenomenon.

[0018] Exemplarily, the first wall has a first section and a second section, the first section is connected between the first end and the second section and is parallel to the mounting plane, and the mounting plane is the plane where the bottom of the second section is located. This arrangement facilitates gas to enter the mixed gas space formed by the first section, the second section and the flame-distributing seat from the gap, and forms a cyclone in the mixed gas space, enhancing the mixing effect of the gas, thereby avoiding the occurrence of flame separation.

[0019] For example, the first section has a length L1, and the length L1 is 7 mm to 20 mm. In this way, the gas can form a cyclone when entering the gas mixing space with this length range, thereby enhancing the mixing effect of the gas.

[0020] Exemplarily, the first wall has a first section and a second section, the first section is connected between the first end and the second section and is inclined relative to the mounting plane, and the mounting plane is the plane where the bottom of the second section is located. Such a configuration facilitates gas to enter the mixed gas space formed by the first section, the second section and the flame-distributing seat from the gap, and forms a cyclone in the mixed gas space, thereby enhancing the mixing effect of the gas and avoiding the occurrence of flame separation.

[0021] For example, the orthographic projection of the first section on the installation plane has a length L2, and the length L2 is 7 mm to 20 mm. In this way, the gas can form a cyclone when entering the gas mixing space with this length range, thereby enhancing the mixing effect of the gas.

[0022] For example, an angle θ is formed between the first section and the mounting plane, and the angle θ is 10° to 30°. This arrangement increases the gas mixing space, thereby enhancing the gas mixing effect, making the gas burn more fully, improving the combustion efficiency, and avoiding the occurrence of flame separation.

[0023] For example, an angle δ is formed between the fire outlet wall and the mounting plane, and the angle δ is 60° to 80°. When the angle is within this range, it is convenient to process the fire outlet holes on the fire outlet wall during production, and when in use, the flame burning at each fire outlet hole can heat the pot well.

[0024] According to another aspect of the utility model, a gas stove is provided, which includes a burner head and the fire cover assembly as described above, and the fire cover assembly is arranged on the burner head. Since the fire cover assembly as described above has the above beneficial effects, the gas stove including the fire cover assembly as described above also has the above beneficial effects, which will not be described one by one here.

[0025] A series of simplified concepts are introduced in the utility model content, which will be further described in detail in the detailed implementation section.

[0041] 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.

[0042] 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.

[0043] The embodiment of the utility model provides a fire cover assembly. The fire cover assembly provided by the utility model is mainly used in a gas stove. The fire cover assembly according to the embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0044] Combined with reference Figures 1 to 3 , the fire cover assembly may include a fire distribution seat 10, a fire cover 20 and a guide plate 30. An air inlet 110 may be provided on the fire distribution seat 10. The fire cover 20 may be provided on the fire distribution seat 10. The fire cover 20 and the fire distribution seat 10 may enclose a gas mixing chamber 40. The guide plate 30 may be provided in the gas mixing chamber 40 and connected to the fire cover 20. Among them, the fire cover 20 may have a fire outlet wall 210 with a fire outlet hole 211. The guide plate 30 may be located between the air inlet 110 and the fire outlet wall 210. In the radial direction of the fire cover 20, the gas mixing chamber 40 may be divided into a first part 410 and a second part 420 by the guide plate 30. The second part 420 may be closer to the fire outlet wall 210 than the first part 410. The second part 420 may be connected to the outside through the fire outlet hole 211. A gap 50 connecting the first part 410 and the second part 420 may be formed between the bottom end 310 of the guide plate 30 and the fire distributor seat 10. The first part 410 is connected to the air inlet 110. The gas entering from the air inlet 110 can first enter the first part 410 and then flow to the second part 420 through the gap 50.

[0045] When the fire cover assembly of the utility model is in use, gas enters the first part 410 from the air inlet 110, a small part of the gas is blocked by the guide plate 30, and flows from the gap 50 formed by the bottom end 310 of the guide plate 30 and the fire distributor 10 to the second part 420, and then flows to the fire hole 211, thereby avoiding the gas from directly flowing out from the fire hole 211 close to the air inlet 110, and further avoiding the flame separation of the fire hole 211 close to the air inlet 110; most of the gas is guided to the fire hole 211 far away from the air inlet 110 through the guide plate 30; thereby, the gas volume of the fire hole 211 near the air inlet 110 and the gas volume of the fire hole 211 far away from the air inlet 110 are guaranteed at the same time, so that the fire holes 211 of the whole circle of the fire cover 20 have uniform gas discharge, so that the flames of each fire hole 211 are relatively uniform, and the flame separation at the fire hole 211 near the air inlet 110 is avoided.

[0046] For example, see Figure 3The gap 50 can be 2 mm to 5 mm, for example, the gap 50 can be 2 mm, 3 mm, 5 mm, etc., and the gap 50 can be 2.5 mm at best. It should be understood that the gap 50 corresponds to the distance S between the bottom end 310 of the guide plate 30 and the upper surface of the fire-distributing seat 10. Such a configuration facilitates the gas to flow from the first part 410 to the second part 420 through the gap 50, and the gap 50 accelerates the gas to quickly form a vortex in the second part 420, thereby improving the mixing effect of the gas.

[0047] For example, referring to Figure 3 and Fig.11 The guide plate 30 may be provided with a plurality of gas supplement holes 320 connecting the first portion 410 and the second portion 420. The plurality of gas supplement holes 320 may be arranged at intervals. In this way, the gas can flow to the second portion 420 through the gas supplement holes 320, thereby avoiding the situation where the amount of gas flowing to the second portion 420 through the gap 50 is insufficient.

[0048] For example, see again Figure 3 , the gas supply holes 320 and the fire outlet holes 211 can be arranged alternately. Such an arrangement enhances the gas mixing effect and improves the combustion efficiency. The fire outlet holes 211 can be arranged alternately in multiple rows. The gas supply holes 320 can be arranged alternately in multiple rows. In this way, the gas supply amount can be increased, and at the same time, it is prevented that the gas directly passes through the fire outlet holes 211 through the gas supply holes 320 to the outside, resulting in insufficient gas mixing, thereby causing the phenomenon of flame separation.

[0049] For example, see Figure 4 , the center line of the adjacent gas supplement hole 320 and the center line of the fire outlet hole 211 may have an angle β, and the angle β may be 0° to 2°, for example, the angle β may be 0°, 1°, 2°, etc. When the angle is within this range, it is convenient for the gas to flow to the fire outlet hole 211 through the gas supplement hole 320, thereby effectively supplementing the gas. When the angle β is 0°, it means that the center line of the adjacent gas supplement hole 320 is parallel to the center line of the fire outlet hole 211, and the gas supplement effect is the best at this time.

[0050] For example, referring to Figure 3 , Figure 6 , Figure 7 and Fig.11 In the circumferential direction of the fire cover 20, the guide plate 30 may be in an arc shape. Specifically, the guide plate 30 may be in an arc shape, an elliptical arc shape, etc. In this way, when the guide plate 30 is in an arc shape, it has a better guiding effect, so that the gas outlet of the fire outlet holes 211 of the whole circle of the fire cover 20 is uniform, so that the flames of each fire outlet hole 211 are relatively uniform.

[0051] For example, referring to Figure 3 and Figure 7In the circumferential direction of the fire cover 20, the guide plate 30 may be in an arc shape, and the guide plate 30 may have a central angle α, which may be 100° to 150°, for example, 100°, 130°, 150°, etc. When the central angle α is 120°, the guide effect of the guide plate 30 is the best. When the central angle of the guide plate 30 is within this range, the guide effect of the guide plate 30 is better, and the central angle of the guide plate 30 is smaller, the guide effect is weakened, and the central angle of the guide plate 30 is larger, resulting in a smaller flame from the partially blocked fire outlet 211.

[0052] For example, again in conjunction with Figure 3 and Figure 7 , the center of the circle to which the guide plate 30 corresponds can be concentric with the center of the fire-distributing seat 10 and the center of the fire cover 20. The fire-distributing seat 10 can be annular, the fire cover 20 can be annular, the gas-mixing chamber 40 formed by the fire-distributing seat 10 and the fire cover 20 can be annular, the guide plate 30 can be arc-shaped, the guide plate 30 and the gas-mixing chamber 40 both extend in the circumferential direction, and the guide plate 30, the fire-distributing seat 10 and the fire cover 20 are coaxial. With such an arrangement, the guide plate 30 has a better guiding effect, so that the gas outlet of the fire outlet holes 211 of the entire circle of the fire cover 20 is uniform, so that the flames of each fire outlet hole 211 are relatively uniform.

[0053] For example, referring to Figure 3 and Figure 6 The guide plate 30 may include at least an arc segment 330, and the center of the circle corresponding to the arc segment 330 may be arranged concentrically with the center of the fire-distributing seat 10 and the center of the fire cover 20. In this way, the arc segment 330 of the guide plate 30 has a good guiding effect, so that the gas outlet of the fire outlet holes 211 of the entire circle of the fire cover 20 is uniform, so that the flames of each fire outlet hole 211 are relatively uniform.

[0054] For example, see again Figure 4 , in the direction parallel to the central axis of the fire cover 20, the guide plate 30 is arc-shaped, and the tangent of the guide plate 30 and the fire outlet wall 210 can form an angle γ, which can be 0° to 10°, for example, the angle γ can be 0°, 5°, 10°, etc. The angle γ can be 0°, at which time the tangent of the guide plate 30 is parallel to the fire outlet wall 210, and the guide effect of the guide plate 30 is the best. In this way, the gas can be effectively guided, so that the gas outlet holes 211 of the whole circle of the fire cover 20 are uniform, so that the flames of each fire outlet hole 211 are relatively uniform, and the mixing effect of the gas can be enhanced, so as to avoid the situation of flame separation in the fire outlet holes 211 close to the air inlet 110.

[0055] For example, referring to Figures 5 to 7, there may be a distance H between the guide plate 30 and the fire outlet wall 210, and the distance H may be 3 mm to 10 mm, for example, the distance H may be 3 mm, 5 mm, 10 mm, etc., and the distance H is preferably 5 mm. Within this distance range, the guide plate 30 has a better guide effect, and avoids the distance between the guide plate 30 and the fire outlet wall 210 being too large, thereby weakening the guide effect of the guide plate 30, and avoids the distance between the guide plate 30 and the fire outlet wall 210 being too small, thereby causing the flame to separate. On the same horizontal plane, when the guide plate 30 is in an arc shape, the distances between the guide plate 30 and the fire outlet wall 210 are equal at all locations, and the guide effect of the guide plate 30 is best.

[0056] For example, see again Figure 3 The fire outlet wall 210 may have a first end 212 and a second end 213. The first end 212 may be closer to the fire distributor seat 10 than the second end 213. The fire cover 20 may also have a first wall 220. The first wall 220 may extend from the first end 212 in a direction away from the guide plate 30 and away from the second end 213, and the first wall 220 and the fire distributor seat 10 may enclose a gas mixing space 430 that communicates with the second portion 420. The gas mixing space 430 may be connected to the air inlet 110 through the gap 50. Such a configuration facilitates the gas to enter the gas mixing space 430 from the gap 50 to form a cyclone, thereby enhancing the mixing effect of the gas and avoiding the occurrence of flame separation.

[0057] For example, see again Figure 3 , the fire cover 20 may also have a second wall 230. The second wall 230 may be connected to the second end 213. The guide plate 30 may have a connecting end 340 arranged opposite to the bottom end 310. The connecting end 340 may be connected to the second wall 230. Specifically, the guide plate 30 may be welded to the second wall 230 through the connecting end 340, and of course it is not excluded that the guide plate 30 may be connected to the second wall 230 by bonding the connecting end 340 to the second wall 230, and the guide plate 30 may also be integrally formed with the second wall 230. In this way, the upper end of the guide plate 30 is connected to the second wall 230 without a gap, thereby preventing the gas from flowing into the fire outlet 211 from between the guide plate 30 and the second wall 230, thereby preventing the fire outlet 211 near the air inlet 110 from leaving the flame. The second wall 230 may extend from the second end 213 toward the bottom wall of the ignition seat 10 , so that oil stains generated during use can flow out from the second wall 230 to avoid flowing into the ignition hole 211 through the second wall 230 , thereby blocking the ignition hole 211 .

[0058] For example, referring to Figures 1 to 4, the first wall 220 may have a first section 221 and a second section 222. The first section 221 may be connected between the first end 212 and the second section 222 and be parallel to the mounting plane. The mounting plane may be the plane where the bottom of the second section 222 is located. The second section 222 may be connected to the fire-distributing seat 10. When the fire cover 20 is in use (i.e., when installed on the fire-distributing seat 10), the mounting plane may be a horizontal plane. Such an arrangement facilitates gas to enter the gas mixing space 430 formed by the first section 221, the second section 222 and the fire-distributing seat 10 from the gap 50, and form a cyclone in the gas mixing space 430, thereby enhancing the mixing effect of the gas and avoiding the occurrence of flame separation.

[0059] For example, once again combined Figure 4 The first section 221 may have a length L1, which may be 7 mm to 20 mm, for example, 7 mm, 13 mm, 20 mm, etc. With this arrangement, the gas entering the gas mixing space 430 having this length range may form a cyclone, thereby enhancing the mixing effect of the gas.

[0060] For example, referring to Figures 8 to 10 , the first wall 220 may have a first section 221 and a second section 222. The first section 221 may be connected between the first end 212 and the second section 222 and may be inclined relative to the mounting plane. The mounting plane may be a plane where the bottom of the second section 222 is located. The second section 222 may be connected to the fire distributor seat 10. When the fire cover 20 is in use (i.e., when mounted on the fire distributor seat 10), the mounting plane may be a horizontal plane. This arrangement facilitates gas to enter the gas mixing space 430 formed by the first section 221, the second section 222 and the fire distributor seat 10 from the gap 50, and to form a cyclone in the gas mixing space 430, thereby enhancing the mixing effect of the gas and avoiding the occurrence of flame separation.

[0061] For example, see Fig.10 The orthographic projection of the first section 221 on the installation plane may have a length L2, and the length L2 may be 7 mm to 20 mm, for example, the length L2 may be 7 mm, 13 mm, 20 mm, etc. With such a configuration, the gas entering the gas mixing space 430 having such a length range may form a cyclone, thereby enhancing the mixing effect of the gas.

[0062] For example, see Fig.10 The first section 221 and the mounting plane may form an angle θ, which may be 10° to 30°, for example, 10°, 20°, 30°, etc. In this way, the gas mixing space 430 is enlarged, thereby enhancing the mixing effect of the gas, making the gas burn more fully, improving the combustion efficiency, and avoiding the occurrence of flame separation.

[0063] For example, see Figure 3and Fig.10 , an angle δ may be formed between the fire outlet wall 210 and the installation plane, and the angle δ may be 60° to 80°, for example, the angle β may be 60°, 70°, 80°, etc. Within this range, it is convenient to process the fire outlet holes 211 on the fire outlet wall 210 during production, and when in use, the flame burning at each fire outlet hole 211 can heat the cookware well.

[0064] The flow process of gas in the fire cover assembly is as follows: the gas flows into the first part 410 from the air inlet 110, most of the gas is transported to the fire hole 211 far away from the air inlet 110 through the guiding effect of the guide plate 30, and a small part of the gas enters the mixing space 430 through the gap 50. The gas forms a cyclone in the mixing space 430 and is fully mixed. It is then transported to the fire hole 211 close to the air inlet 110 through the second part 420, so that the fire holes 211 of the whole circle of the fire cover 20 emit gas evenly, thereby avoiding the uneven flame phenomenon of the fire cover assembly.

[0065] According to another aspect of the utility model, a gas stove is provided. The gas stove may include a burner and the fire cover assembly as described above. The fire cover assembly may be arranged on the burner.
