Gas kitchen ranges

Technical Field

The application relates to the technical field of gas cookers, in particular to a gas stove.

Background

The heat exchange mode of the existing gas stove and cooker mainly comprises three types of heat radiation, heat convection and heat conduction, wherein the heat convection has the highest ratio. The air-fuel (air and gas) mixture gas flowing out of the fire outlet is ignited to form gas in a combustion state. The temperature of the air-fuel mixed gas in the partial combustion state is higher, the heat exchange with the pot bottom is heat convection, and meanwhile, a small part of heat radiation exists; the gas generates high-temperature flue gas after being combusted, the high-temperature flue gas continuously carries out heat convection heat exchange with the pot bottom, and meanwhile, the temperature is gradually reduced in the heat exchange process until the high-temperature flue gas leaves the pot bottom. The pot is placed on the pot support, the temperature of the pot support is raised due to problems of fire baking, high-temperature smoke heating and the like, and therefore heat conduction exists between the pot support and the pot bottom. The main form of the heat exchange between the gas combustion of the gas stove and the boiler bottom is described above.

The existing main mode for improving the heat efficiency of the gas stove is realized by increasing the structure of an energy-gathering cover. Under the condition that the maximum heat load of the gas stove is certain, under the same factors such as the diameter of a cooker, the distance between the cooker and a flame and the like, the heat exchange coefficient between high-temperature flue gas and the bottom of the cooker is basically unchanged, meanwhile, in order to ensure the CO index required by national standard, the high-temperature flue gas cannot stay in the cavity between the bottom of the cooker and an energy-collecting cover all the time, the flue gas index is ensured by adjusting a smoke exhaust gap, the smaller the smoke exhaust gap is, the longer the theoretical stay time of the flue gas is, but the CO exceeds the standard.

Therefore, under the condition that parameters such as heat load (total amount of fuel gas in the fire outlet hole is constant), heat convection heat transfer coefficient is constant, heat transfer area (area of the bottom of the pot) and the like cannot be improved, the heat absorbed by the pot basically reaches a limit value. Therefore, how to improve the heat efficiency of the gas stove is an urgent problem to be solved.

Referring to fig. 1 to 12, the gas stove according to the embodiment of the present disclosure includes a gas stove body, and the gas stove body includes a fire cover assembly 1, a power collecting cover 3, and an energy absorbing member 2.

The energy-gathering cover 3 is sleeved on the outer side of the fire cover component 1 and used for improving the heat efficiency of the gas stove, and the energy-gathering cover 3 mainly improves the heat efficiency through two main modes of reducing ineffective heat loss and reducing flue gas flow rate, namely, improving the heat exchange time of the flue gas and the pot bottom. Wherein the ineffective heat loss comprises: the heat radiation loss of the downward flame (in the direction of the liquid containing tray or the panel), the heat exchange loss of the flame, namely the air-fuel mixed gas and the surrounding secondary air, the heat exchange loss of the high-temperature flue gas and the secondary air and the like, and the energy-gathering cover 3 improves the heat absorbed by the cooker 5 by reducing the ineffective heat loss and improving the contact/heat exchange time of the flue gas and the cooker bottom (the bottom of the cooker 5).

As shown in fig. 3, 7 and 11, the energy collecting cover 3 includes an upper cover 31, a lower cover 32 and a bottom plate 34 sequentially arranged in a top-down direction, the bottom plate 34 may be a liquid containing plate or a panel of a gas range, and a secondary air flow passage 33 is defined between the lower cover 32 and the bottom plate 34.

The fire cover assembly 1 is provided with a fire outlet, the gas stove body further comprises a gas distribution disc, a furnace chamber and an injection pipe, and fuel gas sequentially flows through the injection pipe, the furnace chamber, the gas distribution disc and the fire cover assembly 1 and flows to the fire outlet.

As shown in fig. 1, 5 and 9, the gas burner further comprises an energy absorbing component 2, the energy absorbing component 2 is suitable for being positioned between the gas burner body and the bottom of the cooker 5 and is positioned at the inner side of the outer edge 36 of the energy-gathering cover 3, and the outer edge 36 of the energy-gathering cover refers to the outermost edge of the energy-gathering cover.

The energy-absorbing component 2 is positioned on the inner side of the outer edge 36 of the energy-gathering cover 3, so that the energy-absorbing component 2 is ensured not to be too far away from the fire cover component 1, namely the energy-absorbing component 2 is close to a fire as far as possible, and the energy-absorbing component 2 is subjected to heat conduction by utilizing high-temperature smoke generated by air-fuel mixed gas or gas combustion. Because the energy-absorbing part 2 is located between the gas stove body and the cooker 5, the high-temperature flue gas which conducts heat with the energy-absorbing part 2 exchanges heat with the energy-absorbing part 2 before exchanging heat with the cooker 5, so the temperature of the high-temperature flue gas is higher, the energy-absorbing part 2 is easily heated to a high-temperature state (burning red), the energy-absorbing part 2 in the high-temperature state emits infrared rays and other spectrum forms to carry out heat radiation on the cooker 5, and the high-temperature flue gas which does not exchange heat with the energy-absorbing part 2 continues to exchange heat with the cooker 5 mainly by heat convection. Thereby set up energy-absorbing part 2 back, carry out energy conversion with the high temperature flue gas, after energy transfer to energy-absorbing part 2 with the high temperature flue gas, energy-absorbing part 2 transmits cookware 5 through the form of heat radiation, partly high temperature flue gas has both been utilized, simultaneously with cookware 5's heat transfer in-process, heat radiation and thermal convection can exist simultaneously and do not have the influence mutually, and then richened the heat transfer form of high temperature flue gas and cookware 5, and heat radiation's heat exchange efficiency is higher than thermal convection, make the heat of high temperature flue gas can be more transmit to cookware 5, thereby the thermal efficiency of gas-cooker has been improved.

Optionally, the energy absorbing component 2 is sleeved outside the outlet of the fire outlet, in other words, the energy absorbing component 2 is located between the outer edge 36 of the energy-collecting cover 3 and the outlet of the fire outlet, so that the situation that the energy absorbing component 2 is located inside the outlet of the fire outlet to cause the undersize of the energy absorbing component 2, the heat absorbed by the energy absorbing component 2 from high-temperature flue gas is limited, the energy radiated to the cooker 5 by the energy absorbing component 2 is limited is avoided, and the situation that the arrangement of the energy absorbing component 2 inside the outlet of the fire outlet to cause the structure of the fire cover assembly 1 to be influenced by the arrangement of the energy absorbing component 2 can also be avoided.

The energy absorbing member 2 is positioned above the energy concentrating cover 3, and the energy absorbing member 2 is higher than the upper surface of the upper cover 31, as shown in fig. 3, 7 and 11, and the energy absorbing member 2 is positioned above the upper cover 31. The energy absorbing part 2 is positioned above the energy-gathering cover 3, and the upper part can be directly above or obliquely above.

Energy-absorbing part 2 is located and gathers the energy cover 3 top, on the one hand, guarantee the distance of energy-absorbing part 2 and 5 bottoms of pan (the bottom of a boiler) for energy-absorbing part 2 is located and gathers between energy cover 3 and the bottom of a boiler, and on the other hand can do big energy-absorbing part 2's circumference size, and increase energy-absorbing part 2 is from the heat of absorbing in the high temperature flue gas and heat radiation to the bottom of a boiler's heat, can also avoid energy-absorbing part 2 to influence the structure of fire lid subassembly 1.

Wherein the inner diameter of the energy absorbing member as in figures 4 and 8 refers to the smallest diameter of the portion of the energy absorbing member (second energy absorbing section 22) that is used to absorb the energy of the fire hole, and the inner diameter of the energy absorbing member as in figure 12 refers to the smallest diameter of the energy absorbing member.

If the difference between the inner diameter of the energy-absorbing part 2 and the diameter of the circumference is less than 10mm, the flow area of the communicating channel 4 is reduced, and the amount of secondary air flowing to the outlet of the fire outlet in the secondary air flow channel 33 is reduced; if the difference of the inner diameter of the energy-absorbing part 2 and the diameter of the circumference is larger than 15mm, the radial distance between the energy-absorbing part 2 and the outlet of the fire outlet is too large, and high-temperature smoke can not heat the pathogenic energy part to a high-temperature state capable of carrying out heat radiation with the bottom of a boiler.
