If the heat load is reduced by reducing the gas supply amount, tempering is liable to occur; if the number of the inner ring fire holes or the diameter of the inner ring fire holes is reduced, the phenomena of flame separation and even flame release are easy to occur under the working condition of high heat load inner ring fire. And under the working condition of low heat load, the flame is easy to extinguish under the disturbance of external air.

The jet assembly comprises a jet cavity, a jet part and a flow dividing piece, wherein the jet part is communicated with the jet cavity, and the flow dividing piece is arranged in the jet cavity. One end of the jet flow part is communicated with the jet flow cavity, and the other end of the jet flow part is communicated with the environment space outside the burner, namely the jet flow cavity can be communicated with the environment space outside the burner through the jet flow part. The jet generator is communicated with the jet cavity, and can drive air flow to enter or exit the jet cavity from the jet part. The air flow entering or exiting the jet cavity through the jet part is further recycled in a reciprocating way under the action of the jet generator, and the blowing-sucking processes are continuously carried out at the jet part, and the alternating blowing-sucking processes are overlapped to form jet.

The jet flow part is arranged on the periphery of the first fire outlet hole in a surrounding manner, and the jet flow part continuously performs blowing-sucking under the action of the jet flow generator. Specifically, in the working process of the burner, in the state that the first fire outlet burns out, the air flow temperature at the bottom of the cooker is higher, under the action of the jet flow generator, the jet flow part continuously sucks the gas with lower temperature in the surrounding environment and the hot flue gas on the periphery of the cooker into the jet flow cavity, so that the gas with lower temperature and the high-temperature gas are mixed in the jet flow cavity, and the heat is dissipated towards the surrounding environment through the wall of the jet flow cavity, so that the temperature of the gas in the jet flow cavity is reduced, and then the cooled gas is blown out to the bottom of the cooker to be heated through the jet flow part, so that the temperature of the cooker is reduced, and the effective heat load of the burner is effectively reduced.

The jet flow part is arranged on the periphery of the first fire hole, so that low-temperature gas can uniformly act on the bottom of the cooker, and the cooling effect of the cooker is more uniform. Further, jet flow is formed at the jet flow part, so that on one hand, entrainment of the jet flow to gas near the jet flow part can weaken momentum input of a range hood or external wind, and on the other hand, a low-pressure area is formed at an accessory of the jet flow part due to entrainment of the jet flow part, and the entrainment of flame by the low-pressure area can correct the direction of the flame, weaken the deflection degree of the flame and improve the heating uniformity.

It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.

A burner 100 and a gas range according to some embodiments of the present invention are described below with reference to fig. 1 to 39.

Example 1

As shown in fig. 1, 2, 3, 4, 5 and 6, an embodiment of a first aspect of the present invention proposes a burner 100 comprising a first cover 110, a jet assembly 120 and a jet generator.

Wherein, the first cover 110 is provided with a first fire hole 111; the jet assembly 120 includes a jet cavity 121 and a jet section 122, a splitter 130. The jet flow part 122 is communicated with the jet flow cavity 121, the jet flow part 122 is arranged on the periphery of the first fire outlet hole 111 in a surrounding mode, the flow dividing piece 130 is arranged in the jet flow cavity 121, and the flow dividing piece 130 is used for adjusting air flow distribution in the jet flow cavity 121; the jet generator is communicated with the jet cavity 121; wherein the jet generator is used for driving air flow to enter or exit the jet cavity 121 from the jet part 122.

The burner 100 provided by the application comprises a first cover body 110 provided with a first fire outlet 111, and when the burner 100 works, fuel gas flows out to the outer space of the first cover body 110 through the first fire outlet 111, and burns to form an inner ring flame.

The combustor 100 further includes an inner injector, and the output end of the inner injector is communicated with the inner cavity of the first cover body 110, and outputs the fuel gas to the inner cavity of the first cover body 110.

The magnitude of the heat power of the burner 100 is reflected in the magnitude of the effective heat load, and the higher the heat power, the higher the effective heat load, the faster the heating rate, and the lower the heat power, the lower the effective heat load, and the slower the heating rate. When the inner ring flame heats the cookware, it can be appreciated that the requirements for firepower are not the same when different food materials are cooked. In part, it is desirable to have the burner 100 perform low-fire cooking, i.e., it is desirable to have the burner 100 operate at a low effective heat load.

In order to enable the burner 100 to operate at low effective heat loads, a jet assembly 120 and a jet generator are also provided in the burner 100. The jet assembly 120 includes a jet cavity 121 and a jet portion 122, and the jet portion 122 communicates with the jet cavity 121. Wherein, one end of the jet part 122 is communicated with the jet cavity 121, and the other end is communicated with the environment space outside the burner 100, namely, the jet cavity 121 can be communicated with the environment space outside the burner 100 through the jet part 122. A jet generator is in communication with the jet cavity 121, the jet generator being operable to drive an air flow from the jet section 122 into or out of the jet cavity 121. Specifically, since the jet cavity 121 communicates with the external environment space through the jet part 122, the jet part 122 blows out the gas inside the jet cavity 121, and when the internal space of the jet cavity 121 expands, the jet part 122 winds up the external gas inside the jet cavity 121. Under the action of the jet generator, the above-mentioned processes are reciprocally circulated, and the "blowing-sucking" processes are continuously performed at the jet portion 122, and the alternating "blowing-sucking" processes are overlapped to form jet.

The jet flow portion 122 in the present application is disposed around the first flame outlet 111, and when the burner 100 is operated, the inner ring flame at the first flame outlet 111 heats the pot. The jet part 122 is disposed around the first flame hole 111, and the jet part 122 continuously performs "blowing-sucking" by the jet generator. As can be appreciated, in the state that the first fire hole 111 burns and fires, the jet continuously draws the gas with lower temperature in the surrounding environment and the hot smoke near the first fire hole 111 into the jet cavity 121 through the jet part 122, so that the gas with lower temperature and the high temperature gas are mixed in the jet cavity 121, and the gas radiates heat towards the surrounding environment through the wall of the jet cavity 121, so that the temperature of the gas in the jet cavity 121 is reduced, and then the cooled gas is blown out to the bottom of the heated pot through the jet part 122, so that the pot is cooled, and the effective heat load of the burner 100 is effectively reduced.

Further, when the burner 100 is operated under a low fire condition, the flame is small, resulting in poor flame stability, and the flame is easily deflected by the interference of the range hood or external wind. The burner 100 in the present application is provided with a jet generator, a jet cavity 121 and a jet part 122, and when the jet generator works, the jet generator continuously performs "blowing-sucking" at the jet part 122 to form a jet. On one hand, the entrainment of the jet flow to the gas near the jet flow part 122 can weaken the momentum input of the range hood or external wind, on the other hand, a low-pressure area is formed near the jet flow part 122 due to the entrainment of the jet flow part 122, and the entrainment of the flame by the low-pressure area can correct the direction of the flame, weaken the deflection degree of the flame and improve the heating uniformity.

Further, the jet assembly 120 also includes a splitter 130. Through set up the reposition of redundant personnel piece 130 in jet cavity 121 inside, make the air current through reposition of redundant personnel piece 130 when flowing, played the regulating action to the air current distribution in the jet cavity 121, make air current distribution more even, the pressure in each position of jet part 122 is more balanced, and then makes the low temperature gas that jet part 122 blows out act on the pan bottom more evenly, makes the temperature in each position of pan bottom more even, has promoted the culinary art effect.

According to the burner, the jet generator, the jet assembly 120 and the jet part 122 are arranged in the burner 100, the jet generator can form jet at the jet part 122 through the jet cavity 121, entrainment effect is formed on surrounding air, the relatively low-temperature air can be blown out to a heated cooker through the jet part 122, the temperature of the cooker is lowered, and therefore the effective heat load of the burner 100 is effectively reduced. The jet flow part 122 is arranged on the periphery of the first fire hole 111, so that low-temperature gas can uniformly act on the bottom of the cooker, and the cooling effect of the cooker is more uniform. Further, by forming the jet flow at the jet flow portion 122, on one hand, entrainment of the jet flow to the air near the jet flow portion 122 can weaken momentum input of the range hood or external wind, on the other hand, due to entrainment of the jet flow portion 122, a low pressure area is formed near the jet flow portion 122, and entrainment of the flame by the low pressure area can correct the direction of the flame, weaken deflection degree of the flame, and improve heating uniformity.

The annular main body 131 is arranged around the periphery of the first cover body 110; the first diverting plate 132 is connected to the inner annular surface of the annular body 131.

In this embodiment, the splitter 130 includes an annular body 131, and the annular body 131 is disposed around the circumference of the first cover 110, so as to fully regulate the airflow in the jet cavity 121. The splitter 130 further includes a first splitter plate 132, where the first splitter plate 132 is connected to the inner annular surface of the annular body 131, and the air flow in the jet cavity 121 flows through the first splitter plate 132, so as to play a role in turbulence on the air flow, so that the air flow distribution in the jet cavity 121 is more uniform.

Through set up annular main part 131 and first flow distribution plate 132 in flow distribution piece 130 to set up first flow distribution plate 132 on annular main part 131's interior anchor ring, first flow distribution plate 132 plays the vortex effect to the air current in jet cavity 121, has improved the homogeneity of air current distribution in the jet cavity 121, thereby makes the pressure of each position of jet part 122 more balanced, and the low temperature gas that jet part 122 blown out acts on the pan bottom more evenly, promotes the homogeneity of pan bulk temperature, has promoted the culinary art effect.

Example 3

In this embodiment, the flow divider 130 comprises a first flow divider chamber 133, the first flow divider chamber 133 being arranged on the side facing the jet generator, in correspondence with the inlet 141 of the jet chamber 121. The air flow driven by the jet generator enters the first diversion cavity 133 through the inlet 141, flows into the jet cavity 121 through the first diversion cavity 133, and forms a jet at the jet part 122 through pressure pulsation generated by jet air intake.

By providing the first diversion chamber 133 on the diversion member 130 and arranging the first diversion chamber 133 opposite to the inlet 141 of the jet chamber 121, the jet gas generated by the jet generator can be transferred to the jet chamber 121, and further pressure pulsation is generated to form jet at the jet part 122, and the first diversion chamber 133 guides the jet generated by the jet generator into the jet chamber 121 and is ejected through the jet part 122, so that the air flow entering through the inlet 141 is guided.

Example 4

As shown in fig. 18, 19, 20, 23 and 24, in addition to any of the above embodiments, a burner 100 is provided, in which the first flow dividing plate 132 is an annular plate, and an outer annular surface of the annular plate is connected to an inner annular surface of the annular body 131.

In this embodiment, the first flow dividing plate 132 is an annular plate, the outer annular surface of which is connected to the inner annular surface of the annular body 131, i.e. the first flow dividing plate 132 is arranged circumferentially in the jet chamber 121. By arranging the first splitter plate 132 as an annular plate, the first splitter plate 132 can generate turbulence effect on the air flow at each position in the jet cavity 121, and can play a more balanced adjusting role on the air flow.

Example 5

As shown in fig. 27, 28, 29 and 30, on the basis of any of the above embodiments, this embodiment provides a burner 100, and the flow splitter 130 further includes: the first flow dividing hole 134, the first flow dividing hole 134 is provided on the first flow dividing plate 132, and the first flow dividing hole 134 penetrates the first flow dividing plate 132 in a thickness direction of the first flow dividing plate 132.

In this embodiment, the flow splitter 130 further includes a first flow splitter aperture 134, the first flow splitter aperture 134 being disposed on the first flow splitter plate 132 and penetrating the first flow splitter plate 132 in a thickness direction of the first flow splitter plate 132. When the air flow passes through the first splitter plate 132, part of the air flow passes through the first splitter plate 132 along the inner side wall of the first splitter plate 132, part of the air flow passes through the first splitter plate 132 through the first splitter hole 134 on the first splitter plate 132, the first splitter plate 132 and the first splitter hole 134 jointly perform turbulence on the air flow, the first splitter plate 132 can buffer the incoming high-speed air flow, the effect of uniformly dispersing the air flow is further achieved through the first splitter hole 134, and then the adjusting effect on the flow speed and the distribution of the air flow in the jet cavity 121 is improved.

By arranging the first diversion holes 134 on the first diversion plate 132, on one hand, the first diversion plate 132 and the first diversion holes 134 are used for jointly disturbing air flow, so that the adjusting effect on the air flow in the jet cavity 121 is improved. On the other hand, the weight of the first splitter plate 132 is reduced, so that the product is lighter and the consumption of raw materials is reduced.

Example 6

As shown in fig. 18, 19 and 20, on the basis of any of the above embodiments, this embodiment provides a burner 100 in which the width of the first flow dividing plate 132 gradually decreases from the inlet 141 of the jet cavity 121 toward a direction away from the inlet 141.

In this embodiment, the width of the first flow splitter 132 decreases gradually from the inlet 141 of the jet cavity 121 in a direction away from the inlet 141.

Detailed description of the preferred embodiments

The invention provides an atmospheric gas stove. The atmospheric gas range includes: a first cover 110, a jet cover 160, a second cover 150, a splitter 130, and a mounting block 140.

The first cover 110 is provided with a first flame outlet 111, a second cavity 114, a second air inlet 116, a second flame stabilizing hole 113 and a second slit 112. The second cover 150 is provided with a second flame outlet 151, a first flame stabilizing hole 153 and a first slit 152 on the outer wall, and the upper wall of the second cover 150 is provided with a flame transfer slit 154 and a flame transfer hole 155. The splitter 130 is provided with a first splitter plate 132, a second splitter plate 136, a first splitter cavity 133, a second splitter cavity 135 and a connecting portion 170, and a threaded hole is formed in the connecting portion 170. The mounting seat 140 is provided with an inlet 141, a first air inlet 143, a second air inlet 116 and a counter bore.

Wherein, the assembly relation of each part is as follows: the splitter 130 is disposed above the mounting block 140, the first splitter cavity 133 is aligned with the inlet 141, the second splitter cavity 135 is aligned with the first air inlet 143, and the threaded hole in the connection 170 is aligned with the counterbore and is connected by a screw. The second cover 150 is placed on the upper portion of the mounting seat 140, the jet cover 160, the second cover 150, the splitting piece 130 and the mounting seat 140 together enclose a jet cavity 121, a slit is reserved between the jet cover 160 and the second cover 150, the jet part 122 comprises the slit, and the jet part 122 is located above the jet cavity 121. The second air inlet 116 and the first air inlet 143 are each connected to an outlet of an eductor.

The fuel gas flowing out of the injector enters from the second air inlet 116 and the first air inlet 143 respectively, part of the fuel gas entering into the second air inlet 116 flows out of the first flame outlet 111 and burns in the outer space to form inner ring flame, and the other part of the fuel gas flows into the second slit 112 through the second flame stabilizing hole 113 and burns in the outer space and plays a flame stabilizing role on the inner ring flame of the first flame outlet 111.

The fuel gas entering the first air inlet 143 is split by the second splitter 136, a part of the fuel gas flows out from the second flame outlet 151 and burns in the external space to form an outer ring flame, and the other part of the fuel gas flows into the first flame stabilizing slit through the first flame stabilizing hole 153 and burns in the external space to play a flame stabilizing role on the outer ring flame.

When igniting, the inner ring flame is ignited by the ignition device arranged near the first flame outlet 111, the inner ring flame ignites the fuel gas flowing out of the flame transfer holes 155, and then the flame is transferred to the second flame outlet 151 through the fuel gas flowing out of the flame transfer slits 154 and ignites the outer ring flame.

As shown in fig. 36, in the low-fire operation, no gas flows into the first air inlet 143, and only gas flows into the second air inlet 116, so that the inner-ring flame is maintained to burn while the outer-ring flame is extinguished. At this time, if the effective heat load of the inner ring flame is to be reduced, the synthetic jet control is turned on, and the inlet 141 is connected to the jet generator, which transmits pressure pulsation to the jet part 122 through the inlet 141 and the first flow dividing plate 132, and forms a synthetic jet near the outlet of the jet part 122.

As shown in fig. 37, the eccentric first splitter plate 132 is used to regulate the pressure transmission process in the jet cavity 121, so that the pressure distribution at the jet part 122 is more uniform. The synthetic jet continuously draws the heat-absorbing smoke and the low-temperature air of the surrounding environment into the jet cavity 121, the heat smoke and the low-temperature smoke of the surrounding environment are mixed in the jet cavity 121, the heat is dissipated to the surrounding environment through the jet cover 160, the second cover 150, the flow dividing piece 130 and the wall of the mounting seat 140, and the temperature is greatly reduced and then is sprayed out to the pan bottom area by the jet part 122, so that the temperature of the pan bottom area is reduced, the heat exchange rate of the pan bottom is reduced, and the reduction of the effective heat load is realized.

In addition, as shown in fig. 38, the inner ring flame in the low fire power condition is easily deviated by the suction of the range hood or the interference of the external wind. At this time, as shown in fig. 39, the synthetic jet control is turned on, and on the one hand, entrainment of the synthetic jet with the gas in the vicinity of the outlet of the jet portion 122 can impair the momentum input of the range hood or the external wind. On the other hand, the low pressure region formed by the synthetic jet flow near the outlet of the jet flow part 122 and the entrainment action on the flame can correct the flame direction, weaken the deflection degree of the flame and improve the heating uniformity.

The burner 100 provided by the invention has the following beneficial effects: in a first aspect, the present invention provides a combustor 100 having an ultra-low effective heat load. A jet flow part 122 is arranged at the periphery of the first fire outlet hole 111, and the mixing of the hot flue gas and the ambient low-temperature air and the heat exchange of the hot flue gas and the ambient are enhanced by utilizing the action of the synthetic jet flow to enhance mass transfer and heat transfer. The temperature of the pan bottom area is reduced, thereby reducing the effective heat load. According to experimental determination, after the synthetic jet control is started, the effective heat load can be reduced to about one third of that when the control is not started. In a second aspect, the present invention provides a burner 100 having good wind resistance. A jet flow portion 122 is disposed at the periphery of the first flame outlet hole 111, and momentum input of the range hood or external wind to the inner ring flame is weakened by entrainment of the synthetic jet flow. The low pressure area formed near the outlet of the jet part 122 by the synthetic jet and the entrainment action on the flame are utilized to correct the direction of the flame, weaken the deflection degree of the flame and improve the heating uniformity.

The combustor 100 provided by the invention adopts synthetic jet flow to enhance the heat dissipation of hot flue gas to the surrounding environment, thereby reducing the effective heat load; the synthetic jet flow is adopted to weaken the interference of the suction of the range hood or the external wind to the flame of the inner ring, and the flame direction of the inner ring is corrected; the jet part 122 is arranged around the first fire hole 111 as an outlet of the synthetic jet; the inner ring inlet 141, the first air inlet 143 and the inlet 141 of the jet cavity 121 are independent of each other and do not affect each other; the first flow dividing plate 132 is adopted to adjust the pressure transmission process in the jet cavity 121, so that the pressure distribution at the jet part 122 is more uniform; the second flow dividing plate 136 is used for dividing the fuel gas flowing into the first air inlet 143, so that the flow distribution of the second fire outlet 151 is more uniform.
