Gas cookers are continuously developed as kitchen appliances necessary for cooking in daily life of a home, and heat efficiency is an important performance index of the gas cookers. In order to pursue higher combustion thermal efficiency, gas cookers with energy-collecting pot holders have emerged. The energy-gathering pot frame can play a role in gathering heat energy in cooking, and the combustion heat efficiency is effectively improved.
In the existing energy-gathering pot frame, most of the annular energy-gathering pot frame surrounding the furnace end is of a single-layer structure, smoke of the energy-gathering pot frame is gathered in the energy-gathering pot frame, so that heat exchange between the smoke and the pot bottom is enhanced, but the energy-gathering effect is poor; the multilayer energy-gathering pot frame comprises an inner layer energy-gathering annular plate and an outer layer energy-gathering annular plate, a cavity is formed between the inner layer energy-gathering annular plate and the outer layer energy-gathering annular plate, so that the energy-gathering effect of the energy-gathering pot frame is better, the heat utilization rate of a combustor is improved, the flowing speed of smoke in the energy-gathering pot frame is higher, sufficient heat exchange cannot be carried out, and the heat efficiency of a gas stove is not improved.
Based on the technical scheme, the invention provides an energy-gathering pot frame and a gas stove, and aims to solve the technical problems that in some technologies, the gas stove is high in heat exchange loss, low in heat exchange efficiency, low in energy utilization rate of flue gas and low in combustion heat efficiency of the gas stove.
The embodiment of the invention provides an energy-gathering pot frame, which comprises an energy-gathering disc body 100, wherein a combustion hole for sleeving a combustor is formed in the energy-gathering disc body 100; the energy-gathering disk body 100 comprises a first layer disk 200 and a second layer disk 300 which are arranged at intervals, and an annular cavity 500 surrounding a combustion hole is formed between the first layer disk 200 and the second layer disk 300; at least two check rings 400 surrounding the combustion holes are vertically arranged on the disc surface of the first layer disc 200, and the check rings 400 are arranged at intervals to form a smoke backflow area.
According to the invention, as shown in fig. 2, the first layer of disc 200 and the second layer of disc 300 on the energy collecting disc body 100 form a double-layer structure, the annular cavity 500 between the first layer of disc 200 and the second layer of disc 300 is filled with air, and the annular cavity 500 enables the energy collecting pot frame to have better heat insulation effect because the heat conduction performance of the air is poorer than that of metal; the retaining ring 400 at the innermost layer can weaken the diffusion of secondary air to the outer side of the energy-collecting pot frame, ensure the stability of a temperature field in the central area of the energy-collecting disc and reduce heat exchange loss; the existence of the flue gas recirculation zone enhances the heat exchange degree of the high-temperature flue gas in the flue gas recirculation zone and improves the heat exchange efficiency. The embodiment of the invention improves the heat efficiency of the burner from multiple angles, and solves the technical problems of high heat exchange loss, low heat exchange efficiency, low energy utilization rate of flue gas and low combustion heat efficiency of the existing gas stove.
Specifically, the first layer of disc is annular, a shallow disc and a combustion hole is formed in the middle of the first layer of disc; the second layer of disc is also annular, deep disc, and the centre is seted up the burner port. The outer edge of the first layer disk is connected with the outer edge of the second layer disk, and the inner edge of the first layer disk is connected with the inner edge of the second layer disk. The first layer tray 200 and the second layer tray 300 may be integrally formed or may be separately provided. In the case of the split type, the first-layer disk 200 and the second-layer disk 300 are fixed to each other by screwing or the like, and the first-layer disk 200 is disposed above the second-layer disk 300. It should be noted that, in the case that the inner spaces of the first-layer tray 200 and the second-layer tray 300 are sealed, the annular cavity 500 can perform the functions of heat insulation and heat preservation regardless of being integrally formed or separately arranged.
The combustion hole in the center of the energy collecting disc body 100 is used for installing a burner, and exemplarily, in the present embodiment, the combustion hole is a circular hole. The combustion holes can be in other shapes according to different shapes of the edges of matched combustors.
In this embodiment, the flue gas recirculation zone is composed of two adjacent baffle rings 400 and the space between the two adjacent baffle rings 400, and the number of the baffle rings 400 is at least two. In the use process of the gas stove, smoke flows to the outer edge of the energy-gathering pot frame from the combustion hole in the center of the energy-gathering pot frame through the upper surface of the first layer disc 200, the retainer ring 400 is arranged to form a smoke backflow area between the two retainer rings, the smoke flows in the smoke backflow area in a rotating mode, the flow speed of the smoke can be delayed when the smoke flows through the smoke backflow area, therefore, the flow time of the smoke on the energy-gathering disc body 100 is prolonged, and heat exchange loss is reduced.
Further, the smoke backflow area can change the flow direction of smoke. Specifically, a part of flue gas can be sheltered from by the retaining ring 400 that leans on one side outside and flow back when flowing through flue gas backward flow district, and the flue gas of backward flow flows to the bottom of a boiler along the lateral surface that the retaining ring 400 of inlayer is close to the burner port, has improved the utilization ratio of flue gas and the heat exchange efficiency of flue gas and bottom of a boiler face, has further improved the thermal efficiency of gas-cooker.
In this embodiment, the retaining rings 400 are a plurality of and annular, the retaining rings 400 are coaxially arranged, and a flue gas recirculation zone is formed between every two adjacent retaining rings 400. The fact that the retainer rings 400 are annular and coaxially arranged means that the cross section of each retainer ring 400 is a circular ring with the same center. In this case, the same flue gas recirculation zone formed by two adjacent baffle rings 400 is uniformly arranged in all directions, and the recirculated flue gas is substantially the same in all directions of the combustion holes, so that the uniformity of heat exchange is ensured.
Illustratively, the retainer ring 400 in this embodiment is disposed perpendicular to the lower surface of the second-layer disk 300, and as shown in fig. 3, in a transverse cross-sectional view parallel to the side surfaces, the side surfaces of the retainer ring 400 are vertical straight lines. It should be noted that the side of the retainer ring 400 may also be curved or have other shapes as long as the function of delaying the flow of the flue gas and forming the flue gas recirculation zone is achieved.
In this embodiment, the width of the smoke recirculation zone gradually increases from the center of the energy collecting disk body 100 to the edge of the energy collecting disk body 100. The flue gas backward flow district has a plurality ofly, compares in single flue gas backward flow district, and the existence in multistage flue gas backward flow district can further strengthen the heat exchange degree of high temperature flue gas in the backward flow district, has improved heat exchange efficiency. Because the regional temperature that the upper surface of first layer dish 200 is close to the burner port is lower, and the regional temperature of keeping away from the burner port is higher, and the region of keeping away from the burner port needs bigger backward flow space than the region that is close to the burner port, sets the width in multistage flue gas backward flow district to from the center to the border and increases gradually.
For example, as shown in fig. 4, taking three layers of retaining rings as an example, the innermost retaining ring and the middle retaining ring form a first flue gas recirculation zone, and the middle retaining ring and the outermost retaining ring form a second flue gas recirculation zone. When the high-temperature flue gas flows over the upper surface of the first-layer disk 200, a part of the high-temperature flue gas is blocked by the middle-layer retainer ring to form backflow when flowing through the middle-layer retainer ring, and the other part of the high-temperature flue gas is blocked by the outermost retainer ring to form backflow when flowing through the outermost retainer ring. The width of first flue gas backward flow district is less than the width of second flue gas backward flow district, and the flue gas temperature of second flue gas backward flow district department is higher than the flue gas temperature of first flue gas backward flow district department, and the flue gas backward flow district that the width constantly increases makes the flue gas that the higher temperature responds the great flue gas backward flow district of width, has improved the energy utilization of flue gas.
In this embodiment, the heights of the plurality of baffle rings 400 from the center of the energy collecting disk body 100 to the edge of the energy collecting disk body 100 are gradually increased. Specifically, the upper edges of the respective retaining rings 400 are tangent to the same tangent line in the same direction from the center of the energy collecting disk body 100 to the edge of the energy collecting disk body 100. In this case, the smoke flowing on the upper surface of the first-layer disk 200 is subjected to a smaller tangential force when flowing through the upper edges of the respective retaining rings 400, so that the resistance is reduced, the energy loss of the smoke due to the resistance overcoming during the flowing process is reduced, and the energy utilization rate of the smoke is improved.
In this embodiment, the extension of the first disk 200 has an outer edge, and the outermost retainer ring 400 of the plurality of retainer rings 400 has a height lower than the outer edge. Specifically, the outer edge of the first layer 200 refers to the annular edge formed by the highest point of the first layer 200 away from the burner orifice. Under the condition, the smoke reaching the outer edge can be smoothly discharged out of the energy-gathering pot frame without being blocked, the uniform distribution of a gas pressure field above the energy-gathering disc body 100 is ensured, the full turn of air and fuel gas is facilitated, the combustion efficiency is improved, and the emission of carbon monoxide is reduced.
In this embodiment, the retaining ring 400 at the innermost layer of the retaining ring 400 has an inner annular cavity surrounding the combustion holes, and the inner annular cavity is communicated with the annular cavity 500. The retaining ring 400 at the innermost layer is of a hollow annular structure, so that the volume of the annular cavity 500 can be further increased, and the heat insulation effect of the energy-collecting pot frame is improved. When the gas stove is used, the heat of the energy collecting pot frame is mainly concentrated on the first layer disk 200, and the annular cavity 500 with larger volume can reduce the heat conduction loss of the energy collecting pot frame to the surrounding environment.
Optionally, each of the retaining rings 400 is integrally formed with the first-layer disc 200, and the retaining ring 400 is an annular hollow protrusion protruding from the disc surface of the first-layer disc 200 in a direction away from the second-layer disc 300. Each retainer ring 400 is a hollow annular structure, which can further increase the volume of the annular cavity 500.
In this embodiment, the energy collecting pot holder further comprises a plurality of foot rests 600 for mounting the pot body, and the foot rests 600 are arranged on the first layer of plate 200. Illustratively, there are four foot rests 600, two of which are spaced by 90 °, and the four foot rests 600 are identical, and the upper surfaces and the lower surfaces of the four foot rests 600 are on the same plane. In the use process of the energy-gathering pot frame, the upper surface of the foot rest 600 can support the pot body to provide stable supporting force; the lower surface can be supported on a panel of the gas stove to assist the placement of the energy-collecting pot frame. The uniformly arranged foot rest 600 improves the safety and stability of the energy-gathering pot frame.
The embodiment of the invention also provides a gas stove which comprises a combustor and the energy-gathering pot frame, wherein the energy-gathering pot frame is sleeved on the outer side of the combustor. When the gas range is used, the pot body is set on the foot rest 600 of the energy-collecting pot holder, above the burner.
In this embodiment, the surface of the innermost retainer ring 400 adjacent to the burner and the wall surface of the burner are spaced apart to form a secondary air supply passage 700 communicating with the external environment. When the gas stove is used, the secondary air can enter the combustion hole at the center of the energy collecting pot frame through the secondary air supplement channel 700 to supplement auxiliary combustion. On the other hand, when the secondary air with lower temperature enters the center of the energy-collecting pan, the retaining ring 400 at the innermost layer can reduce the diffusion of the secondary air to the smoke backflow area, and the annular cavity 500 formed by the first layer pan 200 and the second layer pan 300 has the effects of heat insulation and heat preservation, so that the heat exchange between the cold air and the smoke in the central area can be reduced, the stability of the temperature field in the central area of the energy-collecting pan frame is ensured, and the heat exchange loss is reduced.
Alternatively, as shown in fig. 3, the upper edge of each baffle ring 400 is tangent to the same tangent line parallel to the centerline of the burner fire hole 800 in the same direction from the center of the energy collecting disk body 100 to the edge of the energy collecting disk body 100. Specifically, the fact that the tangent line of the upper edge of each baffle ring 400 is parallel to the centerline of the fire hole 800 means that the tangent line is parallel to the centerline of the fire hole 800 in a transverse sectional view parallel to the side. Illustratively, the centerline of the fire holes 800 is located above a tangent to the upper edge of each baffle 400.
In this case, the flue gas flowing out of the fire holes 800 flows in the direction of the outer edge of the energy collecting disk body 100 substantially along the tangent of the upper edge of each retainer ring 400, and the energy utilization efficiency of the flue gas is high, wherein the tangential resistance of the flue gas in the flow is uniform. If the tangent line is not parallel to the centerline of the fire hole 800, for example, the angle between the centerline of the fire hole 800 and the lower surface of the second layer of plate 300 is larger than the angle between the tangent line and the lower surface of the second layer of plate 300, the flue gas flowing out from the fire line may overflow directly to the outside of the energy-collecting pot rack, resulting in energy waste; if the angle between the central line of the fire hole 800 and the lower surface of the second layer of the disc 300 is smaller than the angle between the tangent line and the lower surface of the second layer of the disc 300, most of the flue gas is blocked by the retainer ring 400 close to the combustion hole and cannot flow through the retainer ring 400 far away from the combustion hole, thereby reducing the energy utilization rate of the flue gas.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
