Background

With the popularization of gas stoves in domestic kitchens, the market competition of gas stoves is increasing. The focus of users is on the ability to have greater fire, higher thermal efficiency, easier cleaning, etc.

However, under the premise of large load, the good flame combustion state, the enhanced combustion heat absorption or the reduced heat loss are all modes for improving the heat efficiency of the kitchen range.

When the gas stove generates heat energy, a part of heat is used for heating the cooker, and then the surrounding air is heated by the part of heat through heat radiation, and the cooker support is heated through heat conduction. When the conventional pot support works, heated air can flow freely, heat loss is caused, and the heat efficiency of the gas stove is reduced. The energy-collecting ring can form a physical barrier with flame and external air, so that the rapid loss of smoke is reduced, and the heat loss caused in the process of removing the smoke is reduced.

However, when outside air enters the gas stove to provide oxygen for fuel combustion, the temperature of the air is usually normal temperature, the temperature is greatly different from the ignition temperature of the fuel gas, and the prior art cannot perform good preheating on secondary air, so that the gas stove is easy to damage.

As shown in fig. 1 and 2, the present embodiment discloses a stove comprising a burner 1 and a heat accumulating pan support 2, the heat accumulating pan support 2 being arranged around the burner 1. Specifically, the burner 1 includes an inner ring fire cover 11 and an outer ring fire cover 12, the outer ring fire cover 12 being fitted over the radially outer side of the inner ring fire cover 11, a plurality of fire holes 111 being provided on each of the inner ring fire cover 11 and the outer ring fire cover 12 (the fire holes of the inner ring fire cover and the fire holes of the outer ring fire cover in fig. 1 are each labeled as a fire hole 111) to generate flames. The energy-collecting pot support 2 is sleeved on the radial outer side of the outer ring fire cover 12, and the energy-collecting pot support 2 can form a physical barrier with flame and outside air, so that the rapid loss of smoke is reduced, and the heat loss caused in the discharge process is reduced.

As shown in fig. 3-6, the energy accumulating pan support 2 comprises a body portion 3, a partition plate, a baffle 7 and a foot piece 8.

As shown in fig. 1 to 4, the body 3 in the present embodiment has an annular structure, and the body 3 is disposed around the burner 1, specifically, around the radially outer peripheral side of the outer ring fire cover 12. The body portion 3 comprises an upper wall 31, a lower wall 32, a radially inner side wall 33, a radially outer side wall 34, an annular cavity 35, an air inlet 36 and an air outlet 37. The annular cavity 35 is located inside the body portion 3, specifically the upper wall 31, the lower wall 32, the radially inner side wall 33 and the radially outer side wall 34 of the body portion 3 are connected end to end in sequence to enclose the annular cavity 35. The air inlet 36 is provided on the radial outer side wall 34 of the body 3 and penetrates through both ends of the energy accumulating pan support 2 in the radial direction, one end of the air inlet 36 communicates with the outer space of the energy accumulating pan support 2, and the other end communicates with the annular cavity 35. The air outlet 37 is arranged on the radial inner side wall 33 of the body part 3 and is communicated with the two ends of the energy accumulating pot bracket 2 in the radial direction, one end of the air outlet 37 is communicated with the external space of the energy accumulating pot bracket 2, and the other end is communicated with the annular cavity 35.

As shown in fig. 7, secondary air located at the radial outer side of the energy accumulating pan support 2 can enter the annular cavity 35 through the air inlet 36, and then flows to the burner 1 located at the inner side of the energy accumulating pan support 2 through the air outlet 37, so that secondary air is supplemented to the burner 1, and the fuel gas can be fully combusted. The structure of the annular cavity 35 can gather high-temperature smoke and improve energy efficiency.

Further, as shown in fig. 2, the fire hole 111 of the inner ring fire cover 11 penetrates the radial outer side wall 34 of the inner ring fire cover 11 to form a fire hole, the top of the air outlet 37 is located above the fire hole 111 of the inner ring fire cover 11, the range of the distance h between the top of the air outlet 37 and the center of the fire hole in the axial direction of the energy collecting pot bracket 2 (i.e. the height difference between the top of the air outlet 37 and the center of the fire hole) is 1.2-5mm, i.e. the top of the air outlet 37 is located 1.2-5mm above the center of the fire hole 111 of the inner ring fire cover 11, so that the secondary air discharged from the air outlet 37 can flow to the area where the fuel gas is not fully combusted, thereby improving the combustion efficiency.

Further, as shown in fig. 4, the upper surface of the upper wall 31 of the body 3 in this embodiment is planar and parallel to the horizontal plane, so as to facilitate cleaning of the energy accumulating pan support 2 by the user.

As shown in fig. 4 and 7, the partition plate is provided in the annular chamber 35 and partitions the annular chamber 35 into a heating chamber and a ventilation chamber 63 in the axial direction of the energy accumulating pan support 2, one ends of the heating chamber and the ventilation chamber 63 located on the radially outer side of the energy accumulating pan support 2 are communicated with each other, and one ends of the heating chamber and the ventilation chamber 63 located on the radially inner side of the energy accumulating pan support 2 are closed with each other. The air inlet 36 and the air outlet 37 are provided at both sides of the ventilation chamber 63 in the radial direction of the energy accumulating pan support 2 so as to communicate with the ventilation chamber 63.

The flames of the burner 1 radiate heat to the surrounding air and flue gas and heat transfer heats the body portion 3 of the energy accumulating pan support 2. The secondary air enters the annular chamber 35 through the air inlet holes, and the heat received by the body portion 3 is radiated to the air in the annular chamber 35, and particularly, the air in the heating chamber is heated, so that the temperature of the air in the heating chamber is raised. Because the air inlet 36 and the air outlet 37 are located on both sides of the ventilation chamber 63, air in the ventilation chamber 63 is continuously flowing, the air pressure in the ventilation chamber 63 is smaller than the air pressure in the heating chamber, and the ventilation chamber 63 forms a negative pressure region. And because the heating cavity is communicated with one end of the ventilation cavity 63 positioned at the radial outer side of the energy accumulating pot bracket 2, the heated air in the heating cavity flows towards the ventilation cavity 63 under the action of pressure difference, so that the air in the ventilation cavity 63 is preheated. The newly introduced heated air has a negative velocity, which when mixed with the outside air, reduces the original momentum, thereby increasing the pressure in the negative pressure region. This increased pressure will cause the heated air in the upper 4 and lower 5 baffles to mix with the outside air. The secondary air reaches the burner 1 at a higher temperature, so that the combustion effect is better, the combustion efficiency is improved, and the carbon monoxide emission is reduced.

Specifically, as shown in fig. 4 and 7, the partition plate includes an upper partition plate 4 and a lower partition plate 5, the upper partition plate 4 and the lower partition plate 5 are both disposed in the annular chamber 35 and are disposed at intervals in the axial direction of the energy accumulating pan support 2, and the upper partition plate 4 and the lower partition plate 5 divide the annular chamber 35 into a first heating chamber 61 located above, a second heating chamber 62 located below, and a ventilation chamber 63 located between the first heating chamber 61 and the second heating chamber 62. The air in the first heating chamber 61 is at the highest temperature, the air in the second heating chamber 62 is also preheated, and the ventilation chamber 63 is a passage through which secondary air flows.

One ends of the upper partition plate 4 and the lower partition plate 5 are fixed on the radially inner side wall 33 of the body portion 3, the upper partition plate 4 and the upper wall 31 of the body portion 3 form a first heating chamber 61, the lower partition plate 5 and the lower wall 32 of the body portion 3 form a second heating chamber 62, and one ends of the first heating chamber 61 and the second heating chamber 62, which face the radially inner side wall 33 of the body portion 3, are not communicated with the ventilation chamber 63, so that air in the first heating chamber 61 and the second heating chamber 62 is prevented from flowing out of the air outlet 37 without being fully mixed with air in the ventilation chamber 63. One end of the upper partition plate 4 and the lower partition plate 5, which is far away from the radial inner side wall 33 of the body part 3, has a gap between the radial direction of the energy accumulating pan support 2 and the radial outer side wall 34 of the body part 3, so that air in the first heating cavity 61 and the second heating cavity 62 can flow to the ventilation cavity 63 through the gap, heated air in the first heating cavity 61 and the second heating cavity 62 is mixed with secondary air flowing in from the outside of the energy accumulating pan support 2, the air temperature in the ventilation cavity 63 is increased, and the combustion efficiency is improved.

In this embodiment, the first heating chamber 61 is in contact with the upper wall 31 of the body 3, and the second heating chamber 62 is in contact with the lower wall 32 of the body 3, so that a sufficient heat exchange area with the body 3 is ensured, and the heat transfer effect is improved. The ventilation cavity 63 is arranged between the first heating cavity 61 and the second heating cavity 62, so that the travel of air in the first heating cavity 61 and the second heating cavity 62 flowing to the ventilation cavity 63 is reduced, heat loss is reduced, the temperature of secondary air is higher when the secondary air reaches the burner 1, the combustion effect is better, the combustion efficiency is improved, and carbon monoxide emission is reduced.

Further, the diameters of the upper partition plate 4 and the lower partition plate 5 in the present embodiment are the same, and since one ends of the upper partition plate 4 and the lower partition plate 5 are both fixed to the radially inner side wall 33 of the body portion 3, the distance d between the upper partition plate 4 and the lower partition plate 5 in the radial direction of the energy accumulating pan support 2 and the radially outer side wall 34 of the body portion 3 is the same. Keeping in mind that the diameter of the upper partition plate 4 is phi 1, the diameter of the radial outer side wall 34 of the energy accumulating pot support 2 is phi 2, phi 2 is larger than or equal to phi 1+3mm, namely, the distance d between the upper partition plate 4 and the lower partition plate 5 in the radial direction of the energy accumulating pot support 2 and the radial outer side wall 34 of the body part 3 is larger than or equal to 3mm, thereby ensuring that the air in the heating cavity can smoothly flow to the ventilation cavity 63, ensuring that the air in the heating cavity has enough heating area and accelerating heat exchange.

As shown in fig. 4, 5 and 7, the upper partition plate 4 includes a first lead-in section 41 and a first lead-out section 42 in the radial direction of the energy accumulating pan support 2, the first lead-in section 41 is connected to the outer periphery of the first lead-out section 42, and the first lead-in section 41 is inclined downward from the radial outside of the energy accumulating pan support 2 to the radial inside direction of the energy accumulating pan support 2. Wherein the junction of the first lead-in section 41 and the first lead-out section 42 is curved in transition, i.e., the first lead-out section 42 of the upper separator 4 is curved upward toward one end of the radially outer sidewall 34 of the body portion 3 to form the first lead-in section 41.

As shown in fig. 4,5 and 7, the lower partition plate 5 includes a second introduction section 51 and a second discharge section 52 in the radial direction of the energy accumulating pan support 2, the second introduction section 51 being connected to the outer circumference of the second discharge section 52, the second introduction section 51 being inclined upward from the radial outside of the energy accumulating pan support 2 to the radial inside of the energy accumulating pan support 2. Wherein the junction of the second lead-in section 51 and the second lead-out section 52 is curved in transition, i.e., the second lead-out section 52 of the lower separator 5 is curved downward toward one end of the radially outer sidewall 34 of the body portion 3 to form the second lead-in section 51.

In the present embodiment, the interval between the upper partition plate 4 and the lower partition plate 5 forms the ventilation chamber 63, while the interval between the first lead-out section 42 and the second lead-out section 52 is smaller than the interval between the first lead-in section 41 and the second lead-in section 51, and when secondary air flows from the interval between the first lead-in section 41 and the second lead-in section 51 into the interval between the first lead-out section 42 and the second lead-out section 52, the flow velocity of the secondary air increases and the kinetic energy increases due to the decrease in the flow space. The first and second introduction sections 41 and 51 form a small injection structure so that the air heated by the heating chamber can be rapidly mixed with the secondary air introduced from the outside of the energy accumulating pan support 2.

Specifically, the included angle between the first lead-in section 41 and the first lead-out section 42 is α ₁,120°≤α₁ +.ltoreq.150°. The angle between the first lead-in section 41 and the horizontal plane is beta ₁,15°≤β₁ < 30 deg.. The angle between the second lead-in section 51 and the second lead-out section 52 is alpha ₂,120°≤α₂ < 150 deg.. The angle between the second lead-in section 51 and the horizontal plane is beta ₂,15°≤β₂ -30 deg..

In addition, as shown in fig. 7, since the upper partition plate 4 is inclined upward and the lower partition plate 5 is inclined downward, after the secondary air enters the first heating chamber 61 and the second heating chamber 62, a vortex is formed under the guidance of the curved surfaces of the first introduction section 41 and the second introduction section 51, and a large air flow circulation is formed on the air flow surfaces of the first heating chamber 61 and the second heating chamber 62, as shown by arrows in fig. 7, the flow direction of the secondary air in the heating chamber is indicated, the heated area is increased, and heat exchange is accelerated. The first heating chamber 61 and the second heating chamber 62 form relatively independent vortices, respectively, and both flow out and into the central ventilation chamber 63. The eddy current rotation directions of the first heating cavity 61 and the second heating cavity 62 are opposite, the two eddy currents are mutually converged in the ventilation cavity 63 in the middle and flow to the same to form a coupling structure similar to a gear, and the coupling arrangement structure of multi-partition eddy current and high-frequency heat flow can enhance the turbulence of the air flow eddy current, increase the contact area of secondary air and fully heat cold air.

Further, as shown in fig. 4, the first and second lead-out sections 42 and 52 have the same width in the radial direction of the energy accumulating pan support 2, and are disposed in parallel. Specifically, in the first plane, the ratio of the cross-sectional width a ₁ of the first lead-out section 42 in the radial direction of the energy accumulating pan support 2 to the cross-sectional width b ₁ of the upper partition plate 4 in the radial direction of the energy accumulating pan support 2 ranges from one half to two thirds. In the first plane, the ratio of the cross-sectional width a ₂ of the second lead-out section 52 in the radial direction of the energy accumulating pan support 2 to the cross-sectional width b ₂ of the lower partition 5 in the radial direction of the energy accumulating pan support 2 ranges from one half to two thirds, so that the space between the first lead-out section 42 and the second lead-out section 52 forms a passage through which secondary air flows rapidly. Wherein the first plane is parallel to the vertical plane and passes through the center of the energy accumulating pan support 2.

As shown in fig. 6, the number of the baffles 7 in the present embodiment is plural, the plurality of baffles 7 are all disposed in the annular cavity 35 and are arranged at intervals along the circumferential direction of the energy accumulating pan support 2 and are all fixed on the lower wall 32 of the body portion 3, the plurality of baffles 7 divide the annular cavity 35 into a plurality of separation cavities along the circumferential direction of the energy accumulating pan support 2, and a heating cavity and a ventilation cavity 63 are all formed in any one of the separation cavities. The structure of the multiple separation chambers separates the secondary air in the annular chamber 35 into multiple local vortices, enhances the turbulence of the air flow vortex, increases the secondary air contact area, and enables the cold air and the heated air to be fully fused. Greatly reduces heat loss and improves combustion efficiency.

Further, the outer surface of the baffle 7 is provided with a low-emissivity coating, and the radiation reflectivity of the baffle is reduced by spraying the low-emissivity coating, so that the baffle can be a heat-insulating layer, and heat loss in the airflow flowing process is reduced. The zoned vortices each conduct heat conduction and heat transfer with the heated energy accumulating pan support 2 and heat can be continuously reflected between adjacent baffles 7. The coupling arrangement structure of the multi-distribution vortex and the multi-frequency heat reflection can strengthen the turbulence of the airflow vortex, increase the contact area of secondary air and enable the cold air and the heating air to be fully fused. Meanwhile, the structure can greatly reduce heat loss and improve combustion efficiency.

As shown in fig. 3 and 6, the foot 8 is fixed on the body 3 and partially passes through the annular cavity 35, the upper end of the foot 8 is located above the upper wall 31 of the body 3 to support the cookware, and the lower end of the foot 8 passes through the lower wall 32 of the body 3 to be fixed with the panel of the cookware. Wherein, the lower wall 32 of the body 3 is provided with a through hole 321 for the foot piece 8 to pass through, so as to facilitate the positioning and installation of the foot piece 8.

Further, as shown in fig. 6, a part of the plurality of baffle plates in the present embodiment is formed by an independent baffle plate structure, and the other part is formed by a part of the foot plate 8 disposed in the annular cavity 35, so that on one hand, the foot plate 8 and the body 3 are conveniently fixed, and on the other hand, the number of baffle plates 7 can be reduced, and the cost is reduced.
