Description

Energy-collecting pot rack and gas cooker with same

Technical Field

The utility model relates to the technical field of gas appliances, in particular to an energy-gathering pot rack and a gas cooker with the same.

Background

With the development of society, as a necessary cooking appliance in modern families, the use demands of users are gradually increasing. To increase the thermal efficiency of gas cookers, energy harvesting racks are increasingly selected by users.

Gas cooktops typically have an outer ring fire cover and an inner ring fire cover located inside the outer ring fire cover. The energy-collecting pot rack is generally arranged around the outer ring fire cover, and a certain gap is formed between the bottom of the energy-collecting pot rack and a liquid containing disc of the gas cooker. Air enters the combustion chamber through the gap to supply oxygen for the combustion of the outer ring fire cover and the inner ring fire cover.

The arrangement of the inner ring fire cover or the outer ring fire cover easily causes the problems of insufficient combustion or excessive oxygen, and the heat efficiency is lower.

Disclosure of Invention

In order to at least partially solve the problems of the prior art, according to one aspect of the present utility model, an energy harvesting pot holder is provided. The energy-collecting pot rack comprises an energy-collecting tray, the energy-collecting tray encloses into a combustion chamber, an air inlet communicated with the combustion chamber is arranged on the side face of the energy-collecting pot rack, the energy-collecting pot rack is characterized by further comprising an air distribution tray, an opening through which a burner passes is arranged in the middle of the air distribution tray, wherein the air distribution tray is located below the energy-collecting tray, an upper air inlet channel communicated with an outer ring fire hole in the combustion chamber is formed above the air distribution tray, a lower air inlet channel communicated with an inner ring fire hole in the combustion chamber is formed below the air distribution tray, the air inlet is divided into an upper air inlet and a lower air inlet by the air distribution tray, the upper air inlet is communicated with the upper air inlet channel, and the lower air inlet is communicated with the lower air inlet channel.

In this way, the air separation tray can separate the air taken in from the air inlet into two parts. A part of air sequentially passes through the upper air inlet and the upper air inlet channel to the fire hole of the outer ring to supply oxygen for combustion of the fire cover of the outer ring. The other part of air sequentially passes through the lower air inlet and the lower air inlet channel to the fire hole of the inner ring to supply oxygen for the combustion of the fire cover of the inner ring. The two parts of air are separated from each other and do not interfere with each other. By setting the structure or position of the air dividing plate, the sizes of the upper air inlet and the lower air inlet can be controlled, and the air supply capacity of the upper air inlet channel and the lower air inlet channel can be further controlled. The setting can be more accurate for the burning oxygen suppliment of inner ring fire lid and outer loop fire lid like this, makes the burning of inner ring fire lid and outer loop fire lid more abundant, reduces the oxygen content in the waste gas that the burning produced, improves thermal efficiency. And the gas-separating disc is positioned below the energy-collecting disc, so that a combustion chamber enclosed by the energy-collecting disc is separated from a space below the energy-collecting disc, and the gas-separating disc can play a certain role in heat insulation. By the arrangement, heat energy in the combustion chamber is less prone to radiating downwards, and heat efficiency can be effectively improved. The space above the gas distribution plate will have a higher temperature due to the closer distance to the combustion chamber, which will result in a higher temperature in the upper inlet channel. In the process that air flows to the outer ring fire cover through the upper air inlet channel with higher temperature, the air is preheated to a certain extent, and the heat efficiency is further improved.

Illustratively, the gas distribution plate is a horizontally extending flat plate.

The height of the tray body above the bottom end of the energy accumulating pan frame is typically between 3-9 mm. The heat efficiency and the occupied space can be balanced better through the arrangement, and the structural arrangement is more reasonable.

Illustratively, the inner periphery of the gas distribution plate is provided with a welt bent downward and toward the outer peripheral side of the gas distribution plate, the welt being abutted against the bottom surface of the gas distribution plate. In general, the gas distribution plate adopts a plate body with smaller thickness, and is easier to deform. The setting of welt can strengthen the holistic structural strength of gas separation dish, makes it be difficult for deformation, and the durability is better.

Illustratively, the energy harvesting cooker rack further comprises a support on which the energy harvesting tray is supported and forms an air inlet below the energy harvesting tray. Like this, the air inlet that forms in the below of gathering can the dish need not to gather and can set up air passage on the dish, gathers can the dish and can encircle the combustion chamber better, gathers can the effect better, and the structure setting is more reasonable.

Illustratively, the gas distribution plate is provided with an avoidance gap recessed from the outer periphery to the center thereof, and the support member is provided through the avoidance gap. In the radial direction of the energy-gathering disc, the air distribution disc outwards extends beyond the supporting piece, the lengths of the upper air inlet channel and the lower air inlet channel are longer, and the distribution effect is better. Avoidance of the gap can better increase the stability of the connection of the support member and the gas distribution plate.

Illustratively, the energy accumulating pot rack further comprises a support member on which the air distribution plate is supported, and the energy accumulating plate is supported on which the air inlet is located below the energy accumulating plate. Like this, gather can be understood to become an entity with dividing the gas dish, and this whole supports through support piece, and the structure setting is simple reasonable.

According to another aspect of the present utility model, there is also provided a gas cooker. The gas cooker comprises any energy-collecting pot rack; and a burner comprising an outer ring distributor, the outer peripheral wall of which abuts against the inner periphery of the gas distribution plate.

The burner is an upper air inlet burner, and the upper air inlet burner comprises a nozzle and an outer ring injection pipe communicated with the outer ring distributor, wherein an air outlet of the nozzle and an air inlet of the outer ring injection pipe are positioned in the lower air inlet channel, and the air outlet of the nozzle is aligned with the air inlet of the outer ring injection pipe. The upper air inlet channel and the lower air inlet channel are separated by the air separation disc, so that the mutual interference between the two air inlet channels can be better avoided, and the situation of the mutual interference between the air ejected by the outer ring ejecting pipe and the air required by the combustion of the outer ring fire cover is avoided. Through reasonable setting (for example, the position of dividing the gas dish) of dividing the gas dish, can make the quantity of the air that outer loop injection pipe penetrated and the required air of outer loop fire lid burning all be in more moderate state, make the burning more abundant, reduce the content of the air in the flue gas of arranging, improve thermal efficiency.

Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the utility model. However, it will be understood by those skilled in the art that the following description illustrates preferred embodiments of the utility model by way of example only and that the utility model may be practiced without one or more of these details. Furthermore, some technical features that are known in the art have not been described in detail in order to avoid obscuring the utility model.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present utility model. It will be apparent that embodiments of the utility model may be practiced without limitation to the specific details that are set forth by those skilled in the art. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

According to one aspect of the utility model, an energy harvesting pot holder is provided. Referring to fig. 1, 2 and 5 in combination, the energy harvesting cooker rack 10 includes an energy harvesting tray 100, and the energy harvesting tray 100 may enclose a combustion chamber 110. The burner 40 may be disposed in the combustion chamber 110, and the energy collecting disc 100 is disposed at the outer circumferential side of the burner 40, and may reduce the outward radiation of heat in the combustion chamber 110 to perform an energy collecting function. The sides of the energy harvesting pot holder 10 may be provided with an air inlet 210 in communication with the combustion chamber 110. Air enters the combustion chamber 110 through an air inlet. In the illustrated embodiment, the air inlet 210 is formed by a gap between the energy collecting tray 100 and the liquid containing tray 60 therebelow. In other embodiments, the air inlet may be constructed of any other structure. For example, the energy accumulating pot holder may be provided with an air passage penetrating in the radial direction thereof, and an end of the air passage facing the outer circumferential side of the energy accumulating pot holder constitutes an air inlet. The energy harvesting cooker rack 10 may further include a gas distribution plate 300, and a middle portion of the gas distribution plate 300 may be provided with an opening 350 through which the burner 40 passes. Wherein the gas distribution plate 300 may be positioned below the energy concentrating plate 100. Specifically, the gas distribution plate 300 may be connected to the energy concentrating plate 100 by welding, a connection member connection, or the like in any manner. For example, a support 200 may be provided under the energy concentrating tray 100, and an air distribution tray 300 may be provided on the support 200 to achieve connection with the energy concentrating tray 100. Alternatively, the gas distribution plate 300 and the energy collection plate 100 may be provided separately. When the energy-collecting pot rack is applied to a gas cooker, the gas distribution plate can be connected with other structures in the gas cooker. For example, the gas distribution plate may be fixedly connected to an outer ring distributor of the burner. The combustion chamber 110 is located above the gas separation plate 300.

Referring to fig. 5, an upper intake passage 380 for communicating with an outer ring fire hole 421 in the combustion chamber 110 may be formed above the gas distribution plate 300. A lower intake passage 390 for communicating with the inner ring flame holes 411 in the combustion chamber 110 may be formed below the gas distribution plate 300. Also, the air distribution tray 300 may divide the air inlet 210 into an upper air inlet 211 and a lower air inlet 212. The upper air inlet 211 may be in communication with an upper air intake passage 380 and the lower air inlet 212 may be in communication with a lower air intake passage 390. Thus, the air distribution tray 300 may divide the air entering from the air inlet 210 into two parts. A part of air passes through the upper air inlet 211 and the upper air inlet channel 380 to the outer ring fire hole 421 in sequence to supply oxygen for combustion of the outer ring fire cover 420. Another part of air passes through the lower air inlet 212, the lower air inlet passage 390 and the inner ring fire hole 411 in sequence to supply oxygen for the combustion of the inner ring fire cover 410. The two parts of air are separated from each other and do not interfere with each other. By setting the structure or position of the air dividing tray 300, the sizes of the upper air inlet 211 and the lower air inlet 212, and thus the air supply capacities of the upper air intake passage 380 and the lower air intake passage 390, can be controlled. The arrangement can more accurately supply oxygen for the combustion of the inner ring fire cover 410 and the outer ring fire cover 420, so that the combustion of the inner ring fire cover 410 and the outer ring fire cover 420 is more sufficient, the oxygen content in waste gas generated by the combustion is reduced, and the thermal efficiency is improved. The gas separation plate 300 is positioned below the energy collecting plate 100, so that the combustion chamber 110 surrounded by the energy collecting plate 100 is separated from the space below, and the gas separation plate 300 can have a certain heat insulation effect. By this arrangement, the heat energy in the combustion chamber 110 is less likely to radiate downward, and the heat efficiency can be effectively increased. The space above gas distribution plate 300 is at a higher temperature due to the closer distance from combustion chamber 110, which results in a higher temperature in upper intake passage 380. In the process that the air flows to the outer ring fire cover 420 through the upper air inlet channel 380 with higher temperature, the air is preheated to a certain extent, and the heat efficiency is further improved.

2-4, the gas distribution plate 300 may be in the form of a horizontally extending flat plate. In this way, the collision of the air in the upper air intake passage 380 and the lower air intake passage 390 with the air distribution tray 300 is reduced, and the air flow is smoother. The structure of the gas distribution plate 300 is simpler and the production cost is lower. Of course, the gas distribution plate can be arranged into any other structure according to the use condition, for example, the gas distribution plate can be in an arc-shaped plate shape with the outer part low and the inner part high.

Illustratively, referring to FIG. 4, the gas distribution plate 300 may include a plate body 310 provided with apertures 350 and a flange 320. The flange 320 may be bent outwardly and downwardly from the outer periphery of the tray 310, with the flange 320 forming an angle with the bottom surface of the tray 310 of greater than 90 degrees. In this way, the flange 320 may act as a guide for the incoming air, allowing for a smoother air flow. In some embodiments, the gas distribution plate may not be provided with a flange, and the outer periphery of the gas distribution plate is flush with the plate body.

Illustratively, referring to FIG. 4, the flange 320 may form an angle α with the bottom surface of the tray 310 of between 120-150 degrees. Alpha may be 120 degrees, 135 degrees, 150 degrees, etc. This arrangement further ensures a smooth flow of gas in the upper intake passage 380 and the lower intake passage 390.

Illustratively, with continued reference to FIG. 4, the vertical height H1 of the flange 320 is between 1-5 mm. For example, H1 may be 1mm, 3mm, 5mm, etc. The vertical height H1 of the flange 320 may affect the air flow guiding effect of the flange 320. If the height is too large, the intake efficiency of the lower intake passage 390 may be affected. If the height is too small, the flow guiding efficiency thereof is affected. This arrangement can better balance the flow guiding efficiency of the flange and the air intake efficiency of the lower air intake passage 390. Of course, the vertical height of the flange can be set to any other value according to the use requirements.

Illustratively, referring to FIG. 5, the tray 310 may have a bottom height H2 above the energy harvesting cooker rack 100 of between 3-9 mm. For example, H2 may be 3mm, 6mm, 9mm, etc. It will be appreciated that H2 may affect the ventilation area of the lower intake passage 390 and thus the air supply efficiency of the lower intake passage 390. Too low H2 may result in too low air supply efficiency, insufficient combustion of the inner ring flame cover 410 in communication with the lower air intake passage 390, and low thermal efficiency. Too high a vertical height H2 may result in too much space being taken up by the energy harvesting pot rack 10. The heat efficiency and the occupied space can be balanced better through the arrangement, and the structural arrangement is more reasonable. In an embodiment not shown, the height of the tray above the bottom end of the energy accumulating pan rack may be set to any other value depending on the use requirements.

For example, referring to fig. 4, the inner circumference of the gas distribution plate 300 may be provided with a welt 330 bent downward and toward the outer circumference side of the gas distribution plate 300, and the welt 330 may abut against the bottom surface of the gas distribution plate 300. Typically, the gas distribution plate 300 is formed of a plate body having a smaller thickness, and is relatively deformable. The provision of the welt 330 can strengthen the overall structural strength of the gas distribution plate 300, making it less deformable and more durable. In some embodiments, the inner periphery of the gas distribution plate may not be provided with a welt, and the inner periphery of the gas distribution plate is flush with the plate body.

Illustratively, referring to fig. 3, the energy harvesting pot stand 10 may further comprise a support 200. The energy concentrating tray 100 is supported on the support 200 and forms an air inlet 210 below the energy concentrating tray 100. In particular, the support 200 may be a plurality of support legs, which may better increase the stability of the connection between the gas distribution plate 300 and the support 200. The plurality of support legs may be disposed at intervals in the circumferential direction of the energy concentrating disc 100. The gap between two adjacent support legs may form an air inlet. The gas distribution plate 300 and the support member 200 may be connected by any means, such as welding, interference connection, etc. Like this, the air inlet that forms in the below of gathering can the dish 100 need not to gather and set up air passage on the ability dish 100, gathers can the dish 100 and can surround combustion chamber 110 better, gathers can the effect better, and the structure setting is more reasonable. Illustratively, the energy concentrating disc 100 may include an upper energy concentrating disc 130 and a lower energy concentrating disc 120. An insulating cavity may be formed between the upper and lower energy harvesting trays 130, 120.

Illustratively, referring to fig. 2, the gas distribution plate 300 may be provided with a relief notch 340 recessed from an outer circumference thereof toward the center, and the support 200 may be provided to penetrate the relief notch 340. In this way, the gas distribution plate 300 extends outwardly beyond the support 340 in the radial direction of the energy collecting plate 100, and the upper and lower gas inlet passages 380 and 390 are longer in length, resulting in better gas distribution. The avoidance gap 340 may better increase the stability of the connection of the support 200 and the gas distribution plate 300. In an embodiment not shown, the peripheral edge of the gas distribution plate may not be provided with an avoidance gap, and the peripheral edge of the gas distribution plate is welded to the support member.

Illustratively, the energy harvesting cooker rack may further comprise a support on which the gas distribution plate may be supported, and the energy harvesting plate may be supported on which the air inlet is located below the energy harvesting plate. Like this, gather can be understood to become an entity with dividing the gas dish, and this whole supports through support piece, and the structure setting is simple reasonable.

According to another aspect of the present utility model, there is also provided a gas cooker. Referring to fig. 5, the gas cooker includes any of the energy accumulating pot holders described above and a burner 40. The burner 40 includes an outer ring distributor 430, and an outer peripheral wall of the outer ring distributor 430 may abut against an inner periphery of the gas distribution plate 300. Because the energy-collecting pot rack adopts the technical scheme of any one of the embodiments, the gas cooker has at least the beneficial effects brought by the technical scheme of the embodiment, and the description is omitted here. For example, the combustor 40 may be located within the combustion chamber 110. The burner 40 includes an inner annular flame cover 410 and an outer annular flame cover 420. The inner ring fire cover 410 is provided with an inner ring fire hole 411. The outer ring fire cover 420 is provided with outer ring fire holes 421. The outer ring fire cover 420 may be snapped over the outer ring distributor 430 forming a gas mixing chamber therebetween.

Illustratively, the burner 40 may be an upper inlet air burner that includes a nozzle 50 and an outer ring eductor (not shown) in communication with the outer ring distributor 430. The air outlet of the nozzle 50 and the air inlet of the ejector tube may be located in the lower air inlet passage 390, with the air outlet of the nozzle 50 aligned with the air inlet of the outer ring ejector tube. Typically, the primary and secondary air required for combustion in the upper intake burner are both air above the panel. The nozzle 50 communicates with the fuel gas which is injected into the outer ring injection pipe through the nozzle 50. And injecting air around the outer ring injection pipe into the outer ring injection pipe. The fuel gas and air enter the outer ring distributor 430 through the outer ring injection pipe to be mixed, and flow out through the outer ring fire holes 421 of the outer ring fire cover 420 to be combusted. The air ejected into the outer ring ejecting pipe is the air in the lower air inlet channel 390, and the air required by the combustion of the outer ring fire cover 420 is the air in the upper air inlet channel 380. The upper air inlet channel 380 and the lower air inlet channel 390 are separated by the air separating disc 300, so that the mutual interference between the two air inlet channels can be better avoided, and the situation of the mutual interference between the air ejected by the outer ring ejecting pipe and the air required by the combustion of the outer ring fire cover 420 is avoided. Through reasonable arrangement of the air distributing disc 300 (such as the position of the air distributing disc), the amount of air ejected by the outer ring ejecting pipe and the amount of air required by the combustion of the outer ring fire cover 420 can be in a more moderate state, so that the combustion is more sufficient, the content of air in the discharged flue gas is reduced, and the thermal efficiency is improved.

Illustratively, the outer circumferential surface of the outer ring distributor 430 may have a flange 431 protruding toward the outer circumferential side, and the upper surface of the inner circumferential edge of the gas distribution plate 300 may abut against the lower surface of the flange 431. In this way, the abutting positions of the two form a sealing surface, so that the upper air inlet channel 380 and the lower air inlet channel 390 can be better separated, and the air in the two can be prevented from forming interference. Alternatively, the gas distribution plate may be connected to the outer ring distributor in other ways, for example, the inner circumferential edge of the gas distribution plate may be welded to the outer circumferential surface of the outer ring distributor.

Illustratively, the gas cooker may further include a liquid containing pan 60, the liquid containing pan 60 may include a recess 610 recessed downward from a central portion thereof and a boss 620 surrounding the recess, and the energy harvesting pot holder 10 may be supported on the boss. The liquid tray 60 can collect the soup overflowed in the cooking process, and avoids the influence of the soup flowing to other structures of the gas cooker on the normal use of the gas cooker. Air can enter the combustion chamber 110 through the gap between the liquid containing plate 60 and the energy collecting plate 100, and the structural arrangement is more reasonable.

Illustratively, referring to FIG. 5, the difference between the inner diameter D1 of the energy concentrating disc 100 and the outer diameter D2 of the outer ring distributor 430 is between 5-20 mm. For example, the difference between D1 and D2 may be 5mm, 10mm, 20mm, etc. The difference between the inner diameter D1 of the disc 100 and the outer diameter D2 of the outer distributor 430 can be understood as a gap between the disc 100 and the burner 40. The air required for combustion of the outer ring fire cover 420 needs to enter through the gap. If the difference between the inner diameter D1 of the energy collecting disc 100 and the outer diameter D2 of the outer ring distributor 430 is too small, the outer ring fire cover 420 may be starved of combustion, and the combustion of fuel gas may be insufficient. If too large, the energy gathering effect of the energy gathering pot holder 10 is affected. By the arrangement, the heat efficiency and the energy collecting effect can be balanced better. In other embodiments, the difference between the inner diameter of the energy harvesting disc and the outer diameter of the burner may be any other value.
