Description

Technical Field

[0001] The utility model relates to the field of gas stoves, in particular to a gas supply component and a gas stove comprising the same. Background Art

[0002] Infrared burners play an important role in improving energy utilization and clean use of energy due to their wide range of applications, large adjustable power range, and low pollutant emissions. However, due to their own structural characteristics, infrared burners also have some disadvantages that are relatively inferior to atmospheric burners. Therefore, there are currently burner types that use both infrared burners and atmospheric burners. For example, for a three-ring burner, some of the gas rings use the atmospheric burner solution (such as the gas inner ring), while other gas rings use the infrared burner solution (such as the gas middle ring and outer ring). At the same time, this type of burner will also be equipped with a corresponding blast structure to strengthen the supply of primary air and make the gas burn more fully. However, the setting of a blast structure usually makes the structure of the gas stove bulky and not compact. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defect of the gas stove in the prior art that the structure is not compact, and to provide a gas supply component and a gas stove comprising the same.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A gas supply assembly, comprising:

[0006] an air blast channel, the air blast channel having an air blast outlet;

[0007] a first gas nozzle, the first gas nozzle being arranged corresponding to an infrared burner;

[0008] a second gas nozzle, the second gas nozzle being arranged corresponding to an atmospheric type burner;

[0009] The blast outlet is arranged corresponding to the gas outlet of the second gas nozzle, and the first gas nozzle is arranged in the blast channel and is located upstream of the blast outlet.

[0010] In this solution, the second gas nozzle is set corresponding to the atmospheric burner, and the blast outlet is set corresponding to the air outlet of the second gas nozzle, so that air can be blown to the atmospheric burner through the blast channel to increase the air coefficient corresponding to the atmospheric burner and thus improve the combustion efficiency.

[0011] The first gas nozzle corresponding to the infrared burner is arranged in the blast channel, that is, it is arranged in the blast channel and passes through the blast channel, and the first gas nozzle is located upstream of the blast outlet, so that when blowing through the blast channel, the air needs to bypass the first gas nozzle when flowing through the first gas nozzle in the blast channel, thereby slowing down the air and making the air mixed evenly, thereby improving the uniformity of the mixing of the blasted air and gas to improve the combustion efficiency of the atmospheric burner.

[0012] Compared with additionally providing other structures to slow down and evenly flow the blasted air, slowing down and evenly flowing the blasted air by using the first gas nozzle can make the structure of the gas supply assembly compact.

[0013] Preferably, the blast channel comprises a first extension section located upstream of the blast outlet;

[0014] Along the blowing direction, the cross-sectional area of ​​the first extension section of the blowing channel is larger than the cross-sectional areas of other parts of the blowing channel.

[0015] In this solution, since the cross-sectional area of ​​the first extension section is larger and has a pressure reducing effect, when the air flows in the blast channel to the first extension section, the air can be decelerated so that the air is mixed evenly, thereby further improving the uniformity of the blast air and gas mixture to improve the combustion efficiency of the atmospheric burner.

[0016] Preferably, the blast channel comprises a first extension section located upstream of the blast outlet;

[0017] The blast channel also has a blast inlet located upstream of the first gas nozzle, and the gas supply assembly also includes a blast device, the air outlet of the blast device faces the blast inlet, and the cross-sectional area of ​​the first extension section is larger than the cross-sectional area of ​​the installation chamber of the blast device.

[0018] In the present solution, such an arrangement can reduce the inertia of the air flow and prevent the flame from being blown away by the inertia of the air when the blowing device is turned off.

[0019] Preferably, the first extension section is located upstream of the first gas nozzle.

[0020] In this solution, the first extension section has a stronger effect on evenly mixing the air than the first gas nozzle. This arrangement can improve the effect of air deceleration and uniform flow.

[0021] Preferably, the gas supply assembly further comprises a nozzle mounting seat;

[0022] The first gas nozzle and the second gas nozzle are mounted on the nozzle mounting seat;

[0023] The first extension section is formed in the nozzle mounting seat.

[0024] In this solution, the first extension section is formed in the nozzle mounting seat, so that the gas supply assembly has a compact structure.

[0025] Preferably, the gas supply assembly further comprises a nozzle mounting seat, the nozzle mounting seat comprises a first mounting seat and a second mounting seat, one end of the first gas nozzle and the second gas nozzle protrudes from and is mounted on the first mounting seat, and the other end passes through a mounting hole on the second mounting seat;

[0026] The outer circumference of the first gas nozzle and the inner circumference of the mounting hole are sealed and matched, and the outer circumference of the second gas nozzle and the inner circumference of the mounting hole are gap matched to form the blast outlet.

[0027] In this solution, the first gas nozzle and the mounting hole on the second mounting seat are sealed and matched, which can avoid blowing air to the infrared burner corresponding to the first gas nozzle during blowing. Not blowing air to the infrared burner can avoid the infrared burner temperature being too high, causing the structure in the infrared burner to deform and reduce the service life, avoid excessive heat transfer resulting in high heat dissipation and low utilization, and avoid a large amount of heat being transferred to other structures to cause equipment failure.

[0028] Preferably, the gas supply assembly further comprises a nozzle mounting seat, the nozzle mounting seat comprises a first mounting seat and a second mounting seat, one end of the first gas nozzle and the second gas nozzle protrudes from and is mounted on the first mounting seat, and the other end passes through a mounting hole on the second mounting seat;

[0029] The first mounting seat and the second mounting seat together form at least a portion of the blast channel. The first mounting seat has a convex portion, and a concave cavity is formed in the convex portion, which is concave relative to other portions of the blast channel. The concave cavity is used to form the first extension section. The convex portion is located at one end of the first gas nozzle and the second gas nozzle that protrudes outside the first mounting seat.

[0030] In this solution, the cavity formed in the protrusion on the first mounting seat is used to form the first extension section, and the protrusion is located at one end of the first gas nozzle and the second gas nozzle protruding from the first mounting seat, so that the gas supply assembly has a compact structure.

[0031] Preferably, the blast passage further comprises an blast inlet located upstream of the first gas nozzle, and the blast inlet and the blast outlet are located on the same side of the blast passage.

[0032] In this solution, within the same installation space, such an arrangement can extend the length of the blast channel and improve the deceleration and uniform flow effect of the blast channel on the air. Under the same flow length, such an arrangement can make the structure compact.

[0033] Preferably, the blast channel includes an inlet section and a first extension section sequentially arranged along the blast direction, the blast inlet is formed at the entrance of the inlet section, the cross-sectional area of ​​the first extension section is larger than the cross-sectional area of ​​other parts of the blast channel, and the angle between the extension direction of the first extension section and the extension direction of the inlet section is A, 0°<A≤90°.

[0034] In this solution, the arrangement is such that when the air flows from the inlet section to the first extension section, it can collide with the wall surface of the first extension section, thereby improving the effect of air deceleration and uniform flow.

[0035] Preferably, the blast channel includes a first extension section and a second extension section sequentially arranged along the blast direction, the blast outlet is located downstream of the second extension section, and the angle between the extension direction of the second extension section and the extension direction at the blast outlet is B, 0°<B≤90°.

[0036] In this solution, the arrangement is such that when the air flows from the second extension section to the blast outlet, it can collide with the wall surface at the blast outlet, thereby improving the effect of air deceleration and uniform flow.

[0037] Preferably, the gas supply assembly further comprises a nozzle mounting seat, the first gas nozzle and / or the second gas nozzle is mounted on the nozzle mounting seat, and at least a portion of the blast channel is formed in the nozzle mounting seat.

[0038] In this solution, at least part of the blast channel is formed in the nozzle mounting seat, so that the gas supply assembly has a compact structure.

[0039] Preferably, the nozzle mounting seat has a mounting hole;

[0040] The outer circumferential surface of the second gas nozzle and the inner circumferential surface of the mounting hole are clearance-matched to form the blast outlet.

[0041] In the present scheme, such an arrangement, on the one hand, has a compact structure; on the other hand, can reduce the distance between the gas outlet of the second gas nozzle and the blast outlet, thereby facilitating the mixing of the gas sprayed from the second gas nozzle and the air flowing out of the blast outlet; on the third hand, it is convenient for the blast outlet to surround the second gas nozzle, so that the air surrounds the gas, thereby improving the uniformity of the mixing of air and gas.

[0042] Preferably, the nozzle mounting seat has a mounting hole, and the outer circumferential surface of the first gas nozzle and the inner circumferential surface of the mounting hole are sealingly matched.

[0043] In this solution, such an arrangement can avoid blowing air toward the infrared burner corresponding to the first gas nozzle during blowing.

[0044] Preferably, there are a plurality of second gas nozzles, and the areas of the blast outlets corresponding to at least two of the second gas nozzles are different.

[0045] In this embodiment, such an arrangement can make the blast volumes at multiple blast outlets different, thereby facilitating the gas supply assembly to supply gas to at least two atmospheric burners with different combustion powers, so that the blast volume is adapted to the combustion power of the atmospheric burners.

[0046] A gas stove, comprising:

[0047] A gas supply assembly as described in any of the above technical solutions;

[0051] Preferably, the gas stove further comprises a supplementary air passage connected to the atmospheric burner, and the height of the air inlet of the supplementary air passage is S, 0<S≤3mm.

[0052] In this solution, the blast channel and the supplementary air channel provide air to the atmospheric burner, so that the gas at the atmospheric burner can be fully burned. The air inlet height of the supplementary air channel is 0<S≤3mm, so that S is small enough, thereby making the gas stove compact in height.

[0053] Preferably, there are multiple atmospheric burners, at least two of which are a first burner and a second burner having different combustion powers, and the infrared burner is arranged between the first burner and the second burner.

[0054] In this solution, the infrared burner has a higher air coefficient. By setting the infrared burner between the first burner and the second burner, air can be added to the first burner and the second burner through the infrared burner to improve the combustion efficiency of the first burner and the second burner.

[0055] The positive and progressive effects of the utility model are:

[0056] The first gas nozzle corresponding to the infrared burner is arranged in the blast channel, that is, it is arranged in the blast channel and passes through the blast channel, and the first gas nozzle is located upstream of the blast outlet, so that when blowing through the blast channel, the air needs to bypass the first gas nozzle when flowing through the first gas nozzle in the blast channel, thereby slowing down the air and making the air mixed evenly, thereby improving the uniformity of the mixing of the blasted air and gas to improve the combustion efficiency of the atmospheric burner.

[0057] Compared with setting other structures to slow down and evenly flow the blasted air, slowing down and evenly flowing the blasted air through the first gas nozzle can make the structure of the gas supply assembly compact, thereby making the structure of the gas stove compact.

[0078] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0079] It should be noted that:

[0080] Along the fluid flow direction, the fluid flows from upstream to downstream;

[0081] The cross-sectional area of ​​the fluid flow path (eg, the first extension section) refers to the area of ​​the cross section of the flow channel perpendicular to the fluid flow direction.

[0082] This embodiment provides a gas stove 10000, Figure 1-Figure 9 This is a schematic diagram of the structure provided in this embodiment. Figure 1 , Figure 2 The gas stove 10000 includes a burner 3 and a gas supply assembly. The burner includes an atmospheric burner 32 and an infrared burner 31. The gas supply assembly includes an air blast channel 1 and a gas nozzle 5 for blowing air (supplying primary air) and supplying gas to the burner. The gas nozzle 5 includes a first gas nozzle 51 and a second gas nozzle 52. The first gas nozzle 51 is arranged corresponding to the infrared burner 31, and the second gas nozzle 52 is arranged corresponding to the atmospheric burner 32.

[0083] Specifically, there are two atmospheric burners 32, namely, inner ring burner 321 (i.e., first burner) and outer ring burner 322 (i.e., second burner), and the infrared burner 31 is a middle ring burner 311. The combustion power of the inner ring burner 321, middle ring burner 311, and outer ring burner 322 increases in sequence. The infrared burner 31 has a higher air coefficient, such as Figure 2 By arranging the inner ring burner 321 on the inner side of the middle ring burner 311 and the outer ring burner 322 on the outer side of the infrared burner 31, the infrared burner 31 can be used to supplement air to the inner ring burner and the outer ring burner, thereby improving the combustion efficiency of the inner ring burner and the outer ring burner. In other embodiments, the number and relative position relationship of the atmospheric burner 32 and the infrared burner 31 can be flexibly adjusted, for example, the atmospheric burner 32 is an inner ring burner and a middle ring burner, respectively, and the infrared burner 31 is an outer ring burner, etc.

[0084] Specifically, the first gas nozzle 51 is a middle ring nozzle 511 corresponding to the middle ring burner 311 ; the number of the second gas nozzles 52 is two, namely an inner ring nozzle 521 corresponding to the inner ring burner 321 and an outer ring nozzle 522 corresponding to the outer ring burner 322 .

[0085] like Figure 3-Figure 5 The blast outlet 12 of the blast channel 1 is arranged corresponding to the air outlet of the second gas nozzle 52, that is, the two blast outlets 12 of the blast channel 1, one corresponds to the air outlet of the inner ring nozzle 521, and the other corresponds to the air outlet of the outer ring nozzle 522, so that air can be blown to the inner ring burner 321 and the outer ring burner 322 through the blast channel 1 to improve the combustion efficiency.

[0086] The first gas nozzle 51 is arranged in the blast channel 1 and is located upstream of the blast outlet 12, that is, the middle ring nozzle 511 is arranged in the blast channel 1 and passes through the blast channel 1, and is located upstream of each blast outlet 12. When the air is blasted through the blast channel 1, the air needs to bypass the first gas nozzle 51 when flowing through the first gas nozzle 51 in the blast channel 1, thereby playing a role in slowing down the air and making the air mixed evenly, thereby improving the uniformity of the blasted air and gas mixture to improve the combustion efficiency of the atmospheric burner 32. Compared with setting up other structures to slow down and evenly flow the blasted air, slowing down and evenly flowing the blasted air by the first gas nozzle 51 can make the structure of the gas supply assembly compact.

[0087] like Figure 4The gas stove 10000 also includes three ejector tubes 6, wherein the middle ring ejector tube 62 corresponds to the middle ring nozzle 512 and the middle ring burner 311; the inner ring ejector tube 61 corresponds to the inner ring nozzle 511 and the inner ring burner 321, and the blast outlet 12 corresponding to the inner ring nozzle 511 faces the inlet of the inner ring ejector tube 61; the outer ring ejector tube 63 corresponds to the outer ring nozzle 513 and the outer ring burner 322, and the blast outlet 12 corresponding to the outer ring nozzle 513 faces the inlet of the outer ring ejector tube 63.

[0088] like Figure 3-Figure 5 , the blast inlet 11 of the blast channel 1 is located upstream of the first gas nozzle 51. Figure 3 , Figure 4 The gas stove 10000 also includes a blast device 2, the air outlet of the blast device 2 faces the blast inlet 11, and automatic blowing is performed through the blast device 2. The blast device 2 is specifically a blower. The installation chamber of the blast device 2 is horizontally arranged to prevent the blast device from shaking.

[0089] like Figure 4 , Figure 8 The blast channel 1 includes an inlet section 13, a first extension section 14 and a second extension section 15 which are arranged in sequence along the blast direction; the blast inlet 11 is formed at the inlet of the inlet section 13, and the blast outlet 12 is located downstream of the second extension section 15; along the blast direction, the cross-sectional area of ​​the first extension section 14 (the area of ​​the air flow cross-section perpendicular to the blast direction) is larger than the cross-sectional area of ​​other parts of the blast channel 1. When the air flows to the first extension section 14 in the blast channel 1, the air can be diffused and depressurized to decelerate the air so that the air is mixed evenly, thereby further improving the uniformity of the blasted air and gas mixing to improve the combustion efficiency of the atmospheric burner 32.

[0090] In other embodiments, the cross-sectional area of ​​the first extension section 14 may be set to be larger than the cross-sectional area of ​​the installation chamber of the blast device 2. On the one hand, the deceleration and uniform flow effect of the first extension section 14 on the air can be improved; on the other hand, when the blast device 2 stops running, the flame is easily blown away due to the effect of inertia. The presence of the first extension section 14 will weaken the effect of inertia, so that the flame of the atmospheric burner 32 is stable. In other embodiments, when the cross-sectional area of ​​the first extension section 14 is larger than the cross-sectional area of ​​other parts of the blast channel 1 and the cross-sectional area of ​​the installation chamber of the blast device 2, the deceleration and uniform flow effect is further improved.

[0091] The first extension section 14 is designed to decelerate and evenly flow the air by expanding the cross-sectional area, and has a good deceleration and evenly flow effect on the air. Figure 4 , Figure 5The first extension section 14 is located between the blast inlet 11 and the first gas nozzle 51. When blowing, the air first flows through the first extension section 14 with a larger cross-sectional area to be decelerated, and then further decelerated and uniformly flows through the first gas nozzle 51 after being fully mixed. This arrangement can ensure that the air is fully mixed.

[0092] like Figure 3 The gas supply assembly further includes a nozzle mounting seat 4, and the gas nozzle is mounted on the nozzle mounting seat 4. Specifically, Figure 4-Figure 7 The nozzle mounting seat 4 includes a first mounting seat 41 and a second mounting seat 42. One end of the gas nozzle protrudes from the first mounting seat 41 and is fixed on the first mounting seat 41. The second mounting seat 42 is provided with three mounting holes 421. The other end of the gas nozzle passes through the mounting holes 421 to achieve the installation of the gas nozzle on the nozzle mounting seat 4. In this embodiment, the structures of the gas nozzles are the same, which is convenient for simplifying the structure of the nozzle mounting seat 4, so that the structure of the gas supply assembly and the gas stove 10000 is simple.

[0093] like Figure 4 , Figure 8 The air blast channel 1 is formed in the nozzle mounting seat 4, and is specifically surrounded by the facing surfaces of the first mounting seat 41 and the second mounting seat 42. Correspondingly, the inlet section 13, the first extension section 14, and the second extension section 15 in the air blast channel 1 are also formed in the nozzle mounting seat 4. The first mounting seat 41 and the second mounting seat 42 are respectively formed to jointly surround the air blast channel 1. On the one hand, the processing is convenient. On the other hand, the first mounting seat 41 and the second mounting seat 42 are connected by screws to form a detachable connection, which is convenient for cleaning and maintenance of the air blast channel 1 after disassembly.

[0094] like Figure 4 , Figure 8 The blast inlet 11 and the blast outlet 12 of the blast channel 1 are located on the same side of the blast channel 1, that is, both are located Figure 4 The upper side of the air blast channel 1 in the direction shown is arranged in this way, so that the air path length of the air blast channel 1 can be extended under the same installation space, thereby improving the deceleration and uniform flow effect of the air blast channel 1 on the air; under the same air path length, the structure of the gas supply assembly can be made compact, thereby making the structure of the gas stove 10000 compact.

[0095] Figure 8 The dotted line with an arrow indicates the extension direction of the air blast inlet 11 (i.e., the extension direction of the inlet section 13) and the extension direction of the first extension section 14. There is an angle A between the two, so that when the air flows from the air blast inlet 11 to the first extension section 14, it can collide with the wall surface of the first extension section 14, thereby improving the effect of air deceleration and uniform flow.

[0096] Figure 8The dotted line with an arrow indicates the extension direction of the blast outlet 12 and the extension direction of the second extension section 15. There is an angle B between the two, so that when the air flows from the second extension section 15 to the blast outlet 12, it can collide with the wall surface at the blast outlet 12, thereby improving the effect of air deceleration and uniform flow.

[0097] In this embodiment, A is 90° and B is 90°, so that the air turns at 90°, which has a good deceleration and uniform flow effect on the air. In other embodiments, the values ​​of A and B can be flexibly adjusted, and when 0°<A≤90° and / or 0°<B≤90°, the deceleration and uniform flow effect is better.

[0098] like Figure 5 , Figure 7 The first mounting seat 41 has a convex portion 411, and a concave cavity 4111 is formed in the convex portion 411. The concave cavity 4111 is concave relative to the second extension section 15. The concave cavity 4111 is used to form the first extension section 14 so that the cross-sectional area of ​​the first extension section 14 is larger than the cross-sectional area of ​​the second extension section 15. Figure 7 The protrusion 411 and the protruding portion of the gas nozzle are located on the same side of the first mounting seat 41, and are both located Figure 7 The lower side in the direction shown is arranged in this way, so that the structure of the gas supply assembly can be compact, thereby making the structure of the gas stove 10000 compact.

[0099] like Figure 4 , Figure 5 , the first gas nozzle 51 passes through the mounting hole 421 of the second mounting seat 42, and the outer circumference of the first gas nozzle 51 and the inner circumference of the mounting hole 421 are sealed and matched, so that the first gas nozzle 51 does not form an air blast outlet 12, which can avoid blowing air to the infrared burner 31 corresponding to the first gas nozzle 51. Not blowing air to the infrared burner 31 can avoid the infrared burner 31 from being overheated, causing structural deformation in the infrared burner 31 and reducing its service life, avoiding excessive heat transfer resulting in high heat dissipation and low utilization, and avoiding a large amount of heat being transferred to other structures and causing equipment failure.

[0100] like Figure 4 , Figure 5 The second gas nozzle 52 passes through the mounting hole 421 of the second mounting seat 42, and the outer circumferential surface of the second gas nozzle 52 and the inner circumferential surface of the mounting hole 421 are gap-matched to form the blast outlet 12; on the one hand, the structure is compact; on the other hand, the blast outlet 12 can surround the air outlet of the second gas nozzle 52, so that air surrounds the gas to facilitate full mixing of the air and the gas.

[0101] like Figure 5, two blast outlets 12, the area of ​​the blast outlet 12 corresponding to the inner ring nozzle 521 is smaller than the area of ​​the blast outlet 12 corresponding to the outer ring nozzle 522, so that the blast volume for the inner ring burner 321 is smaller than the blast volume for the outer ring burner 322, so as to match the combustion power of the inner ring burner 321 and the outer ring burner 322.

[0102] In addition, if Fig. 9 The gas stove 10000 is also provided with a supplementary air channel 7, which is connected to the inner ring burner 321 and the outer ring burner 322 of the atmospheric burner 32. Since the blast device 2 is provided to blast the atmospheric burner 32, and the middle ring burner 311 corresponding to the infrared burner 31 can provide air for the atmospheric burner 32, the air inlet height S of the supplementary air channel 7 is set to 2 mm in this embodiment, while ensuring that the atmospheric burner 32 burns fully, S is small enough to make the gas stove 10000 compact in the height direction H. In other embodiments, the number of S can be flexibly adjusted according to the power of the burner, the blast volume, etc., for example, S can be taken as 3 mm, 5 mm, etc. When S≤3 mm, S can be small enough, so that the gas stove 10000 can be compact in the height direction H.
