The application provides an energy collecting disc, which is applied to a gas device provided with a burner 1000, wherein the gas device can be a gas stove, or an assembly of the gas stove and other electrical appliances, or other devices applied with the burner 1000, and the energy collecting disc is taken as an example for the following detailed description.

As shown in fig. 1, 2, 3 and 4, in some embodiments of the present application, the energy collecting disc includes a body 2000 and a retainer 4000, where the body 2000 encloses an inner cavity 2101, so that the body 2000 surrounds the burner 1000, and the body 2000 surrounds the burner 1000 and is fixed to the supporting surface 3000, that is, the body 2000 needs to be mounted to the supporting surface 3000 and supported by the supporting surface 3000, and a gap 5000 needs to be formed between the body 2000 and the supporting surface 3000. Through forming clearance 5000 between body 2000 and the holding surface 3000, so can realizing the holding surface 3000 to the support of body 2000, also can reduce the area of contact between body 2000 and the holding surface 3000, prevent the heat transfer of body 2000 to the holding surface 3000 and cause the deformation or the fracture of holding surface 3000, on this basis, through setting up retaining ring 4000, retaining ring 4000 is used for separating clearance 5000 and inner chamber 2101, avoid high temperature flue gas in the inner chamber 2101 to flow out and lead to the loss of heat through clearance 5000, ensure that the heat obtains make full use of, can avoid external secondary air to enter into inner chamber 2101 uncontrollably through clearance 5000 simultaneously.

Specifically, the energy collecting tray is a structure that can collect heat to avoid excessive heat dissipation, and needs to be matched with the burner 1000 for use. The burner 1000 is a structure in which fuel gas is supplied to the burner and flows out to cause the fuel gas to be ignited to form flame, for example, the burner 1000 includes a burner and an ejector tube, the ejector tube is connected with the burner, the ejector tube is used for being matched with the air supply mechanism to eject the fuel gas toward the burner, and simultaneously, a certain amount of air is ejected to be mixed with the fuel gas to form a mixed gas to be conveyed into the burner, and the mixed gas flows out from the burner to be ignited by an ignition needle.

In general, the air supply mechanism comprises a nozzle, the nozzle receives the gas from the natural gas of the pipeline or the bottled liquefied gas, the nozzle corresponds to the air inlet of the injection pipe, the nozzle sprays the gas into the injection pipe, and meanwhile, the outside air is driven to enter the injection pipe through the air inlet of the injection pipe, so that the gas and the air are initially mixed in the injection pipe, the injection pipe injects and conveys the mixed gas to the furnace end, the furnace end has a larger space relative to the injection pipe, the gas and the air can be further uniformly mixed, and the full combustion of the gas is facilitated. The fire cover structure is generally arranged on the furnace head and is provided with a fire outlet hole, the fire outlet hole is communicated with the interior of the furnace head, and the mixed gas formed by the fuel gas and the air is sprayed out from the fire outlet hole and then is discharged by a nearby ignition needle to be ignited to form flame. It is to be understood that the structure of the burner 1000 is not limited to the foregoing examples.

When the combustor 1000 burns, high-temperature flue gas generated by the combustor 1000 carries heat to be emitted to the periphery, so that the heat is prevented from being lost too quickly along with the high-temperature flue gas, the energy collecting disc is arranged, the body 2000 of the energy collecting disc surrounds the combustor 1000, and heat generated by the combustor 1000 is gathered, so that the too quick heat dissipation is avoided.

The body 2000 is disposed around the burner 1000, the body 2000 is in an annular structure, in this embodiment, the annular shape may be a circular ring shape or a non-circular ring shape (for example, square ring shape), so that the body 2000 encloses the inner cavity 2101, and the body 2000 is in a state surrounding the burner 1000 after the burner 1000 and the energy collecting disc are mounted on the gas stove. It is noted that the circumferential direction is that the body 2000 is located in the circumferential direction of the burner 1000, and the burner 1000 is located in the inner cavity 2101 when viewed along the axial direction of the burner 1000 (for example, up-down direction), so that the body 2000 is referred to as surrounding the burner 1000. The direction of the gas stove is the front side of the gas stove facing the user, the back side of the gas stove facing away from the user, the left side corresponding to the left hand of the user, the right side corresponding to the right hand of the user, the lower side close to the ground and the upper side facing away from the ground.

Generally, since the body 2000 is relatively close to the burner 1000, the body 2000 needs to be made of a high temperature resistant material, for example, a metal material may be used for the body 2000, but the body 2000 is difficult to be insulated, so that heat generated by the burner 1000 is conducted through the body 2000. In addition, since the energy collecting plate is mounted on the supporting surface 3000, the body 2000 needs to be mounted on the supporting surface 3000 to be supported by the supporting surface 3000, the supporting surface 3000 may be a liquid-bearing plate or a panel of a gas stove, the liquid-bearing plate is mostly made of metal, and the panel is made of glass, and of course, the supporting surface 3000 is not limited to the above example, and the supporting surface 3000 can be regarded as the supporting surface 3000 as long as the supporting of the body 2000 can be realized. The heat conducted by the body 2000 is easily transferred to the supporting surface 3000, if the body 2000 is attached to the supporting surface 3000, the supporting surface 3000 is easily deformed or broken, for this purpose, in this embodiment, a gap 5000 is provided between the body 2000 and the supporting surface 3000, and under the premise of ensuring that the supporting surface 3000 effectively supports the body 2000, the contact area between the supporting surface 3000 and the body 2000 can be reduced, so that the heat transferred by the body 2000 towards the supporting surface 3000 is reduced, and the supporting surface 3000 is prevented from being deformed or broken.

When the gap 5000 is formed between the body 2000 and the supporting surface 3000, then the inner cavity 2101 can be communicated with the outside through the gap 5000, along with continuous combustion of the burner 1000, high-temperature smoke can be continuously generated in the inner cavity 2101, the high-temperature smoke can flow upwards to meet the blocking of the heated object 7000, then change direction to emit around, in the process, the high-temperature smoke can flow to the outside through the gap 5000 except for emitting around due to the blocking of the heated object 7000, and therefore, the heat carried by the high-temperature smoke flowing to the outside through the gap 5000 can not heat the heated object 7000, but is wasted. In addition, during the combustion process of the burner 1000, external secondary air can enter the inner cavity 2101 through the gap 5000, and the entry of the external secondary air is uncontrollable and is a passive entry, which is not beneficial to the stable combustion of fuel gas.

Therefore, in this embodiment, by providing the retainer 4000, the retainer 4000 is also annular, so that the burner 1000 can be surrounded, and the retainer 4000 can separate the gap 5000 from the inner cavity 2101, so that the inner cavity 2101 is formed into a relatively closed space, and the high-temperature flue gas generated in the inner cavity 2101 almost flows upwards to heat the heated object 7000, so that the secondary air is prevented from flowing away from the gap 5000, and the external secondary air is difficult to enter the inner cavity 2101 through the gap 5000, so that the burner 1000 for actively supplementing the secondary air is more suitable. It will be appreciated that since the baffle 4000 serves to separate the gap 5000 from the cavity 2101, the wall thickness of the baffle 4000 can be made sufficiently thin so that the contact area of the baffle 4000 with the support surface 3000 is also sufficiently small.

In some embodiments of the present application, the retainer 4000 is configured to abut the support surface 3000 under the force of gravity, which makes it easier to separate the gap 5000 from the inner cavity 2101 and also facilitates the installation of the retainer 4000.

Specifically, the installation accuracy of the retainer 4000 is easily affected by machining errors and installation errors, if the installation of the retainer 4000 is easily deviated, the gap 5000 and the inner cavity 2101 cannot be well separated, so in this embodiment, the retainer 4000 is designed to be abutted against the supporting surface 3000 under the action of gravity, that is, when the installation of the retainer 4000 is performed, the retainer 4000 is not easily affected by other components, but the contact of the retainer 4000 along the circumferential direction of the retainer 4000 and the supporting surface 3000 can be realized under the action of gravity, so that the assembly accuracy can be improved, and the separation of the gap 5000 and the inner cavity 2101 is ensured. And, the retaining ring 4000 is supported on the supporting surface 3000 under the action of gravity, that is to say, the retaining ring 4000 is easy to be disassembled, and a user can disassemble the retaining ring 4000 against the gravity direction, so that the cleaning is convenient. It will be appreciated that, since the baffle 4000 is required to separate the gap 5000 from the cavity 2101, the height of the baffle 4000 is required to be higher than the height of the gap 5000,

As shown in connection with fig. 2, 4 and 5, in some embodiments of the present application, the body 2000 includes a support portion 2210, and the body 2000 is supported on the support surface 3000 by the support portion 2210, such that a gap 5000 is formed between the body 2000 and the support surface 3000.

Specifically, the support portion 2210 protrudes downward from the main body 2000, and the support portion 2210 may have a plurality of support portions, which are alternately arranged along the circumferential direction of the main body 2000, so as to improve the support stability, and the arrangement of the support portion 2210 can reduce the contact area between the main body 2000 and the support surface 3000. It is understood that the supporting portion 2210 may be a separate structure with respect to the body 2000 and connected to the body 2000 by a connection means, and may also be an integrally formed structure with the body 2000.

For example, the body 2000 is made of metal, and the support portion 2210 can be formed by stamping a part of the body 2000 due to the high ductility of metal. The punched support 2210 is formed with a cavity so that the holder 6000 can be installed, and the holder 6000 is used for the heated object 7000 to rest thereon.

With continued reference to fig. 2 and 4, in some embodiments of the present application, the body 2000 includes a second disc 2200 and a first disc 2100, the second disc 2200 is configured to be disposed around the first disc 2100, an outer cavity 2201 is formed between the second disc 2200 and the first disc 2100, and the first disc 2100 encloses an inner cavity 2101, so that the first disc 2100 may be disposed around the burner 1000.

Specifically, the first tray 2100 is closer to the burner 1000 than the second tray 2200, and because the first tray 2100 cannot be insulated, the first tray 2100 also has heat conduction and then dissipates heat outwards, so in this embodiment, by designing the outer cavity 2201 between the second tray 2200 and the first tray 2100, the heat dissipation of the inner cavity 2101 through the conduction of the first tray 2100 can be prevented to a certain extent, and the heat preservation effect on the inner cavity 2101 is enhanced.

Further, in some embodiments of the present application, as shown in fig. 1 and 3, the outer cavity 2201 is designed to be open, so that during the flow of the high-temperature flue gas, at least a part (for example, a part) of the high-temperature flue gas enters into the outer cavity 2201, and another part of the high-temperature flue gas can directly flow out of the outside, so that the temperature of the outer cavity 2201 can be raised, and then the heat can be retransmitted back to the heated object 7000, so as to avoid the too fast dissipation of the heat.

The outer chamber 2201 is designed to be open to the object 7000 to be heated, so that the high-temperature flue gas generated by the burner 1000 flows upward and diverges when it encounters the obstacle of the object 7000 to be heated, and since the outer chamber 2201 is open to the object 7000 to be heated, a part of the high-temperature flue gas is facilitated to enter the outer chamber 2201.

In addition, with respect to the inner cavity 2101 being a high temperature region, the outer cavity 2201 is a low temperature region, and the open end of the outer cavity 2201 (the open end is the opening of the outer cavity 2201) needs to be arranged at the outer side of the inner cavity 2101, so that the heat carried by the high-temperature flue gas flows to the open end of the outer cavity 2201 and then enters the outer cavity 2201 on the premise that the inner cavity 2101 and the heated object 7000 perform sufficient heat exchange, and the heat exchange with the heated object 7000 is continuously realized in the outer cavity 2201, so that the heat carried by the high-temperature flue gas can be fully utilized, and the energy efficiency is effectively improved.

In some embodiments of the present application, as shown in fig. 6, the first tray 2100 is designed to be an integral structure with the retainer 4000, so that the amount of material is reduced, and the assembly of the entire energy collecting tray is facilitated.

Specifically, the integrally formed structure of the first disc 2100 and the retaining ring 4000 may be that the first disc 2100 and the retaining ring 4000 may be formed by casting with a mold, or the first disc 2100 and the retaining ring 4000 may be manufactured by a plate and based on punching, bending, stamping, or the like, so that the first disc 2100 and the retaining ring 4000 may be integrated into one piece, thereby reducing the amount of materials. When the energy collecting disc is installed on the gas stove, the first disc body 2100 and the check ring 4000 can be synchronously disassembled and assembled, so that the gas stove is convenient and quick.

As shown in connection with fig. 8, in some embodiments of the present application, the top portion 2110 of the first tray 2100 is spaced apart from the heated object 7000, and a side of the top portion 2110 of the first tray 2100 facing the heated object 7000 is defined as a guide side 2111, and the guide side 2111 is designed to be parallel to the heated object 7000.

Specifically, by arranging the diversion side 2111, the diversion side 2111 and the heated object 7000 are designed to be parallel to each other, so that when high-temperature flue gas flows between the diversion side 2111 and the heated object 7000, laminar flow is formed, and the flow of the high-temperature flue gas is accelerated by the laminar flow, so that the scouring of the heated object 7000 is enhanced, the convection heat transfer coefficient is improved, more efficient heat transfer is realized, and the heat transfer effect is further improved. It will be appreciated that so-called parallel flow guiding sides 2111 form a flow path between the corresponding parts of the object 7000 to be heated, and that the flow area of the flow path is relatively constant in the direction of the flow of the high temperature flue gas, so that a laminar flow is formed.

For example, the top 2110 of the first tray 2100 forms a diversion side 2111, the diversion side 2111 is horizontally disposed, the diversion side 2111 corresponds to the bottom of the heated object 7000, and is spaced from the bottom of the heated object 7000, when the heated object 7000 is a pot, the diversion side 2111 corresponds to the bottom of the pot, a flow channel is formed between the diversion side 2111 and the pot bottom, and when the flue gas is discharged through the gap between the diversion side 2111 and the pot bottom, laminar flow can be formed, and scouring of the pot bottom is enhanced, so that the convective heat transfer coefficient is improved.

In order to ensure that an effective laminar flow is formed between the diversion side 2111 and the heated object 7000, as shown in fig. 2, in some embodiments of the application, the energy collecting disc further comprises a support 6000, on which the heated object 7000 is arranged to rest, so as to be spaced from the diversion side 2111, and the distance between the diversion side 2111 and the highest point of the support 6000 is H, which is 2 mm.ltoreq.h.ltoreq.10mm, especially when H is 4 mm.ltoreq.h.ltoreq.6mm, which has a better laminar flow effect, and which satisfies the use of different heated objects 7000.

It is to be understood that the bracket 6000 may be disposed on the first disc 2100 or the second disc 2200, and of course, the bracket 6000 may be fixed in both the first disc 2100 and the second disc 2200, and may be disposed according to practical situations.

In some embodiments of the present application, as shown in fig. 2, the first disk 2100 includes a first ring 2120, where the first ring 2120 extends vertically, so that the space of the inner cavity 2101 can be reduced, thereby reducing the heat dissipation area, and achieving more effective heat collection in the inner cavity 2101.

Specifically, the first ring 2120 abuts the retainer 4000 and the top 2110 of the first disk 2100, and the first ring 2120 extends vertically, which may be that the first ring 2120 and the retainer 4000 both extend vertically, and the angle θ between the extending direction of the first ring 2120 and the vertical direction is 0 °, so that the range of the inner cavity 2101 is as small as possible (as long as the installation of the burner 1000 is not disturbed), and when the inner cavity 2101 is smaller, the heat dissipation area is reduced, which is beneficial to reducing the heat dissipation. In addition, when the first ring 2120 extends vertically, the diversion side 2111 formed by the top 2110 of the first disk 2100 may be wider under the same size of the first disk 2100, so that the high-temperature flue gas enters into a laminar flow state earlier, and a larger area of laminar flow flushing can be formed between the diversion side 2111 and the heated object 7000, which is beneficial to further improving the convective heat transfer coefficient and realizing more efficient heat transfer.

It should be noted that when the first ring 2120 extends vertically, the flame will contact the first ring 2120 due to the upward flame of the burner 1000, especially at the junction of the first ring 2120 and the top 2110 of the first disk 2100, which will block the flame and cause insufficient combustion, resulting in an increase in the amount of carbon monoxide, for example, and therefore, as described in connection with fig. 4 and 7, in some embodiments of the present application, the angle θ between the extending direction of the first ring 2120 and the vertical direction satisfies 0 ° < θ+.60 °, i.e., the first ring 2120 is designed to be flared upward from bottom to top, so that the flame is prevented from being blocked by the first ring 2120, especially the angle θ is designed to satisfy 10+.ltoreq.40°, which can ensure both laminar flow formation and sufficient combustion.

As shown in connection with fig. 4 and 7, in some embodiments of the application, the top end 2121 of the first ring 2120 needs to be designed higher than the top surface 1100 of the burner 1000, while the bottom end 2122 of the first ring 2120 needs to be designed lower than the top surface 1100 of the burner 1000, so that the flame divergence is better satisfied.

Specifically, the top end 2121 of the first ring 2120 may be considered as a junction between the first ring 2120 and the first disk 2100, and the bottom end 2122 of the first ring 2120 may be considered as a junction between the first ring 2120 and the retainer 4000, so that when the flame generated by the burner 1000 is generated upwards, i.e. corresponds to the first ring 2120 having a horn shape, the first ring 2120 is less likely to block the flame,

The application also discloses a gas stove, and the gas stove comprises the energy collecting disc of the embodiment, as shown in fig. 1 and 3, it can be appreciated that the energy collecting disc of the gas stove adopts the technical scheme of the embodiment, so that the gas stove at least has the beneficial effects brought by the technical scheme of the embodiment and is not repeated here.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the scope of the application, and all equivalent structural changes made by the specification and drawings of the present application or direct/indirect application in other related technical fields are included in the scope of the present application.
