Description

Technical Field

[0001] This application relates to the field of kitchen and bathroom appliances technology, and in particular to a high-efficiency pot support and a gas stove. Background Technology

[0002] The thermal efficiency of a gas stove is an important parameter reflecting its energy efficiency. Using a heat-concentrating pot support to reduce heat loss and improve gas combustion efficiency can effectively improve the thermal efficiency of the gas stove.

[0003] However, due to heat conduction, some of the heat from the stove fire is still transferred to the boiler support, and this heat is then directly lost into the air. The boiler support's function is to limit heat loss, not to improve the combustion efficiency of the gas. Therefore, how to recover and utilize the heat lost into the air has become a pressing technical problem in this field. Utility Model Content

[0004] The energy-efficient cooker support and gas stove provided in this application reduce the toxic and harmful gases produced by incomplete combustion of gas by improving the combustion efficiency of gas and the thermal efficiency of the gas stove.

[0005] This application provides a power-concentrating pot support, comprising:

[0006] A concentrating ring, the concentrating ring having a first side and a second side opposite each other in the axial direction;

[0007] Multiple foot pieces are connected to the energy-concentrating ring body and are arranged at intervals along the circumference of the energy-concentrating ring body. The multiple foot pieces at least partially protrude from the second side of the energy-concentrating ring body to support the cookware.

[0008] An energy-concentrating disk is arranged around the outer periphery of the energy-concentrating ring, and a flow-guiding cavity is formed between the energy-concentrating disk and the energy-concentrating ring.

[0009] The flow guiding cavity has:

[0010] An air inlet is arranged around the outer periphery of the energy-concentrating ring and facing the first side of the energy-concentrating ring. The air inlet is used to allow air to enter the flow guide cavity.

[0011] An air outlet is arranged around the outer periphery of the energy-concentrating ring and facing the second side of the energy-concentrating ring. The air outlet is used to allow air in the guide cavity to flow out of the guide cavity. The first side and the second side are opposite sides of the energy-concentrating ring in the axial direction.

[0012] The energy-concentrating disk is connected to a plurality of foot plates to connect with the energy-concentrating ring body, and the size of the air outlet is smaller than the size of the air inlet in the radial direction of the energy-concentrating ring body.

[0013] The energy-concentrating cooker support of this application comprises a circumferentially extending energy-concentrating disk arranged around the outer periphery of an energy-concentrating ring. The energy-concentrating disk is connected to the energy-concentrating ring via multiple feet fixed to it, and the energy-concentrating disk and the energy-concentrating ring are spaced apart to form a flow-guiding cavity surrounding the energy-concentrating ring. The flow-guiding cavity has an air inlet and an air outlet extending around the outer periphery of the energy-concentrating ring, located on opposite sides of the energy-concentrating ring in the axial direction. In the radial direction of the energy-concentrating ring, the size of the air outlet is smaller than the size of the air inlet. With this design, when heating cookware using a gas stove equipped with this energy-concentrating pot support, the flame inside the pot support consumes oxygen in the air and heats other gases, creating a negative pressure inside the pot support compared to the outside. Under this negative pressure, air from outside the pot support enters the guide chamber. Because the outlet is smaller than the inlet, based on the Venturi effect, the air pressure at the outlet is lower than the inlet pressure, causing the air to flow upwards continuously. The increased air velocity at the outlet further encourages the continuous entry of air from outside the pot support into the guide chamber. This air enters the guide chamber and convects with the surface of the energy-concentrating ring, exchanging heat. After absorbing heat, the air's temperature rises and it flows upwards to the bottom of the cookware, thus recovering heat from the pot support and using it to heat the cookware. Simultaneously, the air reaching the bottom of the cookware can be used as secondary air for gas combustion, ensuring complete combustion and reducing the production of toxic and harmful gases due to incomplete combustion.

[0014] In one possible implementation, the energy-concentrating ring body comprises:

[0015] The ring body portion, the foot piece fixedly connected to the ring body portion, the energy-concentrating disk surrounding the ring body portion, the ring body portion comprising:

[0016] An inclined wall portion having a second side extending radially outward from the energy-concentrating disk, the inclined wall portion being inclined from the air inlet toward the air outlet, and the inclined wall portion being arranged around the center of the energy-concentrating disk to form the air inlet with the energy-concentrating disk;

[0017] An extended wall portion is connected to the inclined wall portion and located on the second side of the inclined wall portion. The extended wall portion is arranged to converge toward the inner side of the energy-concentrating disk relative to the inclined wall portion. The extended wall portion is arranged around the center of the energy-concentrating disk to form the air outlet between the extended wall portion and the energy-concentrating disk.

[0018] The outer ring wall of the energy-concentrating ring includes an inclined wall and an extended wall. Extending radially outward from the energy-concentrating plate, the inclined wall is angled towards the air outlet, meaning it expands and extends in that direction. The extended wall connects to the inclined wall and is located on the second side of the inclined wall, converging towards the inner side of the energy-concentrating plate relative to the inclined wall. This results in a smaller portion of the energy-concentrating ring facing the first side. When the energy-concentrating pot support is installed on the gas stove, the energy-concentrating ring can be closer to the burner and enclose the outer perimeter of the burner, thus confining the heat of the flame within a smaller space and reducing heat loss. Because the inclined wall expands and the extended wall converges relative to the inclined wall, the heat from the flame near the bottom of the pot can be appropriately distributed within the space defined by the inclined wall and the extended wall, ensuring even heating of the bottom of the pot and preventing uneven heating or even damage to the pot due to excessive heat concentration at the bottom. Furthermore, because the extended wall is relatively inclined and converged, when air flows out from the air outlet, the extended wall can play a certain guiding role, causing the air to move appropriately toward the center of the energy-concentrating pot support, ensuring that the preheated air can reach the bottom of the pot to heat the pot.

[0019] In one possible implementation, the extended wall portion is a curved wall portion that protrudes toward the energy-concentrating disk, and the extending direction of the inclined wall portion is parallel to the tangent at the junction of the curved wall portion and the inclined wall portion.

[0020] The extended wall is designed as a curved wall protruding towards the energy-concentrating disk, and the extension direction of the inclined wall is parallel to the tangent of the curved wall at the connection point with the inclined wall. This allows the outer ring wall of the energy-concentrating ring to smoothly transition from the air inlet to the air outlet, reducing wind resistance and turbulence within the guide cavity, thus lowering noise. Simultaneously, increasing the airflow velocity improves the efficiency of heat recovery from the energy-concentrating ring.

[0021] In one possible implementation, the inclined wall portion includes:

[0022] The first sub-wall portion extends radially toward the outer side of the energy-concentrating disk, and extends obliquely from the air inlet toward the air outlet. The first sub-wall portion is arranged circumferentially around the center of the energy-concentrating disk to form the air inlet with the energy-concentrating disk.

[0023] The second sub-wall portion is connected between the first sub-wall portion and the extended wall portion. The second sub-wall portion extends obliquely toward the inner side of the energy-concentrating disk relative to the first sub-wall portion. The second sub-wall portion is arranged circumferentially around the center of the energy-concentrating disk.

[0024] The inclined wall portion includes a first sub-wall portion and a second sub-wall portion, extending radially outward along the energy-concentrating plate. The first sub-wall portion extends inclinedly towards the air outlet, i.e., it is expanded, forming an air inlet between the first sub-wall portion and the energy-concentrating plate. The second sub-wall portion connects the first sub-wall portion and the extended wall portion, extending inclinedly towards the inner side of the energy-concentrating plate relative to the first sub-wall portion, i.e., it is converged. Thus, the distance between the first sub-wall portion and the energy-concentrating plate is greater than the distance between the second sub-wall portion and the energy-concentrating plate. In other words, the air inlet of the guide cavity is larger than the portion of the guide cavity above the air inlet. When heating cookware with a gas stove equipped with this energy-concentrating pot support, it is easier to create a pressure difference between the air inlet and outlet of the guide cavity, allowing air from outside the energy-concentrating pot support to enter the guide cavity, thereby enabling continuous airflow from outside the energy-concentrating pot support into the guide cavity for waste heat recovery.

[0025] In one possible implementation, the energy-concentrating disk includes:

[0026] An inclined plate portion extends radially toward the outer side of the energy-concentrating ring body, extending obliquely from the air inlet toward the air outlet. The inclined plate portion is arranged around the outer periphery of the inclined wall portion to form the air inlet with the inclined wall portion.

[0027] An extension plate portion is connected to the inclined plate portion. In the axial direction of the energy-concentrating ring, the extension plate portion is arranged to converge toward the inner side of the energy-concentrating ring relative to the inclined plate portion. The extension plate portion is arranged around the outer periphery of the extension wall portion to form the air outlet with the extension wall portion. The extension plate portion is connected to a plurality of foot plates.

[0028] The energy-concentrating plate includes an inclined plate and an extension plate, extending radially outward from the energy-concentrating ring. The inclined plate extends obliquely from the air inlet towards the air outlet, forming the air inlet with the inclined wall. The extension plate is connected to the inclined plate and located on the second side of the inclined plate. The extension plate is converging towards the inner side of the energy-concentrating ring relative to the inclined plate, forming the air outlet with the extension wall. That is, by converging the extension plate, the size of the air outlet is smaller than the size of the air inlet, creating a cavity that is narrower at the top and wider at the bottom. Simultaneously, because the extension plate is converging relative to the inclined plate, when air flows out from the air outlet, the extension plate acts as a guide, causing the heat-absorbing air to flow appropriately towards the center of the energy-concentrating pot support, ensuring that the heat-absorbing air reaches the bottom of the pot and is used to heat it.

[0029] In one possible implementation, the extension plate portion is a curved plate portion that protrudes outward toward the outer side of the energy-concentrating ring, and the extension direction of the inclined plate portion is parallel to the tangent at the connection between the curved plate portion and the inclined plate portion.

[0030] The extension plate is designed as a curved plate protruding outwards from the outer edge of the energy-concentrating ring, and the extension direction of the inclined plate is parallel to the tangent at the junction of the curved plate and the inclined plate. This allows the energy-concentrating disk to smoothly transition towards the inner wall of the energy-concentrating ring, helping to reduce wind resistance when air flows in the guide cavity, reducing airflow turbulence inside the guide cavity, and thus reducing noise. Simultaneously, increasing the airflow velocity improves the efficiency of heat recovery from the energy-concentrating ring.

[0031] In one possible implementation, the energy-concentrating ring further includes:

[0032] A flow guide plate is connected to the extended wall portion and located on the second side of the extended wall portion. The flow guide plate extends from the extended wall portion toward the outer ring of the energy-concentrating plate. The flow guide plate is used to guide the airflow in the flow guide cavity toward the cookware.

[0033] The energy-concentrating ring also includes a guide plate disposed on the extended wall. Axially, the guide plate extends from the main body of the ring towards the outer side of the energy-concentrating disk to guide the airflow in the guide cavity towards the underside of the cookware. By using the guide plate to guide the airflow, the preheated air in the guide cavity can flow to the underside of the cookware and heat it when it exits the air outlet. It also prevents the air exiting the air outlet from directly blowing onto the stove flame, thus preventing any interference with the normal heating of the stove.

[0034] In one possible implementation, the deflector includes:

[0035] An arc-shaped bend is connected to the extended wall portion, and the arc-shaped bend bends toward the outer side of the ring of the energy-concentrating disk to form a groove with an opening toward the outer side of the ring of the energy-concentrating disk, and the opening of the groove communicates with the air outlet.

[0036] An air guide section is connected to the side of the arc-shaped bend section away from the ring body section, and the air guide section extends obliquely from the arc-shaped bend section toward the outer side of the ring of the energy-concentrating disk.

[0037] The baffle plate includes an arc-shaped bend and an air-guiding section. The arc-shaped bend is connected to the extended wall and bends towards the outer edge of the energy-concentrating disc to create a groove with its opening facing the outer edge of the energy-concentrating ring. The opening of the groove communicates with the air outlet. This arc-shaped bend design reduces the air resistance of the baffle plate to the air flowing from the air outlet, allowing for smooth airflow. Simultaneously, because the groove's opening faces the outer edge of the energy-concentrating disc and communicates with the air outlet, and the groove's inner wall is arc-shaped, when foreign objects such as particles fall into the groove, they can automatically detach from the groove under gravity and enter the baffle cavity, then automatically fall along the baffle cavity to the outside of the energy-concentrating pot support for easy cleaning. During gas stove use, because the bottom of the pot obstructs the flame, the flame is distributed from the center of the energy-concentrating pot support to the outer edge. However, most of the heat from the flame is still concentrated in the central area of ​​the energy-concentrating pot support, while the area near the periphery of the pot receives less heat and has a lower temperature. The air guide extends at an angle towards the outer edge of the energy-concentrating plate, preventing air from the outlet from blowing directly onto the flame and affecting its operation. Simultaneously, air that has recovered heat from the energy-concentrating pot support flows from the outlet towards the outer edge of the support ring, heating the perimeter of the pot's bottom and improving heating uniformity. Furthermore, the outward-distributed flame comes into contact with the secondary air flowing from the outlet towards the outer edge of the support ring, ensuring more complete combustion of the fuel in that area and reducing the production of toxic and harmful gases caused by incomplete combustion.

[0038] In one possible implementation, the foot plate includes:

[0039] The foot piece body is fixedly connected to the ring body and protrudes from the ring body to support the cookware;

[0040] The abutting part is connected to the foot plate body. The abutting part is located on the side of the foot plate body outside the ring of the energy-concentrating ring. The abutting part abuts against the side of the guide plate facing the energy-concentrating disk to cooperate and fix with the guide plate.

[0041] The foot plate includes a foot plate body and an abutment portion. The foot plate body is fixedly connected to the ring body and protrudes from the ring body to support the cookware. The abutment portion is connected to the foot plate body and is located on the outer side of the foot plate body on the energy-concentrating ring. The abutment portion abuts against the side of the guide plate facing the energy-concentrating plate. In this way, based on the mutual fixation of the foot plate body and the ring body, the cooperation between the abutment portion and the guide plate further strengthens the bonding strength between the foot plate and the energy-concentrating ring.

[0042] In one possible implementation, the foot plate includes:

[0043] The foot piece body is fixedly connected to the energy-concentrating ring body and protrudes from the first side of the energy-concentrating ring body. The foot piece body is used to support the cookware.

[0044] A connecting part, one end of which is connected to the foot piece body and extends along the axial direction of the energy-concentrating ring towards the energy-concentrating disk; the connecting part is located on the side of the foot piece body outside the ring of the energy-concentrating ring.

[0045] The ear is connected to the other end of the connecting part. The energy-concentrating disk has a clearance opening corresponding to the ear. The connecting part extends into the clearance opening. The ear is located in the flow-guiding cavity and abuts against the energy-concentrating disk to prevent the foot from detaching from the energy-concentrating disk.

[0046] The foot piece includes a foot piece body, a connecting part, and an ear. The connecting part is connected to the foot piece body and extends along the axial direction of the energy-concentrating ring towards the energy-concentrating disk. The connecting part is located on the outer side of the foot piece body outside the energy-concentrating ring. The ear is connected to the end of the connecting part near the energy-concentrating disk. The energy-concentrating disk has a clearance opening corresponding to the ear, and the connecting part extends into the clearance opening. The ear is located in the flow guiding cavity and abuts against the energy-concentrating disk. In this way, the part of the ear in the flow guiding cavity can form a stop engagement with the part of the energy-concentrating disk that forms the clearance opening, so that the energy-concentrating disk is hooked onto the ear, and the energy-concentrating disk will not separate from the ear under unexpected circumstances.

[0047] In one possible implementation, the energy-concentrating disk includes:

[0048] A first disk body extends circumferentially along the energy-concentrating ring body;

[0049] The second disc extends circumferentially along the energy-concentrating ring and is arranged opposite to the first disc. The first disc and the second disc are connected end to end to surround the outer periphery of the energy-concentrating ring. The first disc and the second disc are provided with the clearance opening at the connection point corresponding to the lug.

[0050] By configuring the energy-concentrating plate as a first plate and a second plate connected end to end, and providing a clearance opening at the connection point between the two plates, a portion of the mounting lug can enter the flow guide cavity when the first and second plates are aligned from opposite directions during installation, facilitating the installation of the energy-concentrating plate. If the energy-concentrating plate needs to be replaced due to deformation or damage, it can be disassembled by separating the first and second plates, facilitating maintenance of the energy-concentrating pot support.

[0051] The second aspect of this application discloses a gas stove that includes the energy-concentrating pot support described in any of the preceding claims.

[0052] The gas stove of this application, by incorporating the aforementioned energy-concentrating pot support, allows for the recovery of heat from the pot support via natural convection through the guide cavity of the support when heating cookware, and this recovered heat is then used to heat the cookware, thereby improving the gas stove's thermal efficiency. Simultaneously, the preheated air within the guide cavity can be used as secondary air for gas combustion, ensuring complete combustion, improving combustion efficiency, and reducing toxic and harmful gases produced by incomplete combustion.

[0053] Compared with the prior art, the beneficial effects of this application are as follows:

[0054] The energy-concentrating cooker support of this application comprises a circumferentially extending energy-concentrating disk arranged around the outer periphery of an energy-concentrating ring. The energy-concentrating disk is connected to the energy-concentrating ring via multiple feet fixed to it, and the energy-concentrating disk and the energy-concentrating ring are spaced apart to form a flow-guiding cavity. The flow-guiding cavity has an air inlet and an air outlet extending around the outer periphery of the energy-concentrating ring, located on opposite sides of the energy-concentrating ring in the axial direction. In the radial direction of the energy-concentrating ring, the size of the air outlet is smaller than the size of the air inlet. With this design, when heating cookware using a gas stove equipped with this energy-concentrating pot support, the flame inside the pot support consumes oxygen in the air and heats other gases, creating a negative pressure inside the pot support compared to the outside. Under this negative pressure, air from outside the pot support enters the guide chamber. Because the outlet is smaller than the inlet, based on the Venturi effect, the air pressure at the outlet is lower than the inlet pressure, causing the air to flow upwards continuously. The increased air velocity at the outlet further encourages the continuous entry of air from outside the pot support into the guide chamber. This air enters the guide chamber and convects with the surface of the energy-concentrating ring, exchanging heat. After absorbing heat, the air's temperature rises and it flows upwards to the bottom of the cookware, thus recovering heat from the pot support and using it to heat the cookware. Simultaneously, the air reaching the bottom of the cookware can be used as secondary air for gas combustion, ensuring complete combustion and reducing the production of toxic and harmful gases due to incomplete combustion.

[0072] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0073] In this application, the terms "upper," "rear," "inner," "outer," and "middle," etc., indicate orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing the present invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0074] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0075] Furthermore, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable link, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection via an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0076] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0077] Thermal efficiency is one of the most important indicators of a gas stove. Higher thermal efficiency means a higher proportion of the heat generated during use is effectively utilized. Improving the thermal efficiency of a gas stove allows for the same heating effect with less gas, helping to save gas and reduce energy waste. The main ways to improve thermal efficiency include reducing heat loss, heat recovery and reuse, and improving gas combustion efficiency. Related technologies generally use a heat-concentrating pot support to concentrate heat. During use, the space between the pot support and the pot is relatively small, confining most of the heat within this space and minimizing loss. Heat recovery and reuse typically involves collecting the high-temperature flue gas generated by the flame through pipes and using this flue gas to heat water, etc. Improving gas combustion efficiency generally involves providing sufficient air for combustion, preventing incomplete combustion due to insufficient air.

[0078] Because the space between the energy-concentrating cooker support and the cookware is relatively small, there is relatively little air around the flame, making incomplete combustion of the gas more likely. Furthermore, even though the energy-concentrating cooker support can effectively reduce heat loss, some heat from the stove fire will still be transferred to the support due to heat conduction, and the heat from the support will then be transferred to the air. In other words, even with an energy-concentrating cooker support, heat loss still occurs.

[0079] Based on the above, embodiments of this application provide a concentrating pot support. A circumferentially extending concentrating disk is arranged around the outer periphery of the concentrating ring. The concentrating disk is connected to the concentrating ring via multiple feet fixed to it, and the concentrating disk and the concentrating ring are spaced apart to form a flow guide cavity. The flow guide cavity has an air inlet and an air outlet extending around the outer periphery of the concentrating ring, located on opposite sides of the concentrating ring in the axial direction. In the radial direction of the concentrating ring, the size of the air outlet is smaller than the size of the air inlet. With this design, when heating cookware using a gas stove equipped with this energy-concentrating pot support, the flame inside the pot support consumes oxygen in the air and heats other gases, creating a negative pressure inside the pot support compared to the outside. Under this negative pressure, air from outside the pot support enters the guide chamber. Because the outlet is smaller than the inlet, based on the Venturi effect, the air pressure at the outlet is lower than the inlet pressure, causing the air to flow upwards continuously. The increased air velocity at the outlet further encourages the continuous entry of air from outside the pot support into the guide chamber. This air enters the guide chamber and convects with the surface of the energy-concentrating ring, exchanging heat. After absorbing heat, the air's temperature rises and it flows upwards to the bottom of the cookware, thus recovering heat from the pot support and using it to heat the cookware. Simultaneously, the air reaching the bottom of the cookware can be used as secondary air for gas combustion, ensuring complete combustion and reducing the production of toxic and harmful gases due to incomplete combustion.

[0080] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0081] Please see Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the structure of the energy-concentrating pot support in the embodiments of this application. Figure 2 yes Figure 1 The diagram shown is a top view of the energy-concentrating cooker support. Figure 3 yes Figure 2 The diagram shows a cross-sectional view of the energy-concentrating cooker support along the B-B' direction.

[0082] In some embodiments, the energy-concentrating pot support 1 includes an energy-concentrating ring 11, which is a ring-shaped component, such as a circular ring. In use, the energy-concentrating ring 11 is generally arranged around the outer periphery of the burner head. Most of the heat generated by the flames emitted from the burner head is confined within the space defined by the energy-concentrating ring 11 and the pot, thereby reducing heat loss.

[0083] In some embodiments, the energy-concentrating ring 11 is a hollow ring, meaning that the energy-concentrating ring 11 constructs an annular cavity 11a filled with air. This allows the air in the cavity 11a to enhance the heat insulation effect of the energy-concentrating ring 11, further reducing heat loss. Simultaneously, by making the energy-concentrating ring 11 a hollow ring, its weight can be reduced, and the materials required for its manufacture can be decreased, achieving both a lightweight design and lower manufacturing costs.

[0084] In some embodiments, the energy-concentrating cooker support 1 further includes a plurality of feet 12 connected to the energy-concentrating ring 11 and arranged at circumferential intervals along the energy-concentrating ring 11. The plurality of feet 12 at least partially protrude from the energy-concentrating ring 11 to support the cookware. It is understood that the plurality of feet 12 protrude from the same side of the energy-concentrating ring 11 and support the cookware on that side.

[0085] Optionally, there are at least three foot pieces 12. These three foot pieces 12 provide at least three support points for the cookware. The three support points are coplanar, which improves the support effect and keeps the cookware stable. This embodiment uses four foot pieces 12 as an example, but it is not intended to imply that the following content applies only to this example.

[0086] In some embodiments, the energy-concentrating pot support 1 further includes an energy-concentrating disk 13, which is connected to a plurality of foot pieces 12 and to an energy-concentrating ring body 11 via the plurality of foot pieces 12. The energy-concentrating disk 13 is arranged around the outer periphery of the energy-concentrating ring body 11, and a flow guiding cavity 13a is formed between the energy-concentrating disk 13 and the energy-concentrating ring body 11. It is understood that the energy-concentrating disk 13 is also an annular member, surrounding the outer periphery of the energy-concentrating ring body 11.

[0087] In some embodiments, both the energy-concentrating ring 11 and the energy-concentrating disk 13 are annular, and their centers coincide. Of course, in some embodiments, the energy-concentrating ring 11 and the energy-concentrating disk 13 can also be configured with other shapes, and their relative positions can be adjusted appropriately according to their shapes and the actual scenario. For ease of description, the following description uses the example of both the energy-concentrating ring 11 and the energy-concentrating disk 13 being annular, with their centers coinciding, but this does not mean that the following content applies only to this example.

[0088] In some embodiments, the flow guiding cavity 13a has an air inlet 13b, which is arranged around the outer periphery of the energy-concentrating ring 11 and facing one side of the energy-concentrating ring 11 in its own axial direction. The air inlet 13b is used to allow air to enter the flow guiding cavity 13a. The flow guiding cavity 13a also has an air outlet 13c, which is arranged around the outer periphery of the energy-concentrating ring 11 and facing the other side of the energy-concentrating ring 11 in its own axial direction P. The air outlet 13c is used to allow air in the flow guiding cavity 13a to flow out of the flow guiding cavity 13a.

[0089] It should be noted that, in this embodiment, the two opposite sides of the energy-concentrating ring 11 along its own axial direction can be divided into a first side P1 and a second side P2. For example, the opening of the air inlet 13b faces the first side P1 of the energy-concentrating ring 11, and the opening of the air outlet 13c faces the second side P2 of the energy-concentrating ring 11.

[0090] In some embodiments, the size of the air outlet 13c is smaller than the size of the air inlet 13b in the radial direction of the energy-concentrating ring 11. With this configuration, when heating a cookware using a gas stove with this energy-concentrating pot support 1, the flame within the space defined by the energy-concentrating pot support 1 consumes oxygen in the air and heats other gases, creating a negative pressure inside the energy-concentrating pot support 1 compared to the outside. Under this negative pressure, air from outside the energy-concentrating pot support 1 enters the guide cavity 13a. Because the size of the air outlet 13c is smaller than the size of the air inlet 13b, based on the Venturi effect, the air pressure at the air outlet 13c is lower than the air pressure at the air inlet 13b, causing the air to continuously flow upwards. Furthermore, the air velocity at the air outlet 13c increases, prompting air from outside the energy-concentrating pot support 1 to continuously enter the guide cavity 13a. The air entering the guide cavity 13a convects with the surface of the energy-concentrating ring 11, exchanging heat. After absorbing heat, the air temperature rises and flows upwards to the bottom of the cookware, thereby recovering heat from the energy-concentrating pot support 1 and using it to heat the cookware. Meanwhile, the air reaching the bottom of the cookware can be used as secondary air for the combustion of the gas, ensuring complete combustion and reducing the production of toxic and harmful gases such as CO and NO caused by incomplete combustion. Furthermore, the secondary air is preheated in the guide chamber 13a, resulting in a higher temperature, which reduces the temperature difference between the secondary air and the furnace fire, thus preventing a decrease in combustion efficiency due to a large temperature difference between the secondary air and the furnace fire.

[0091] Please see also Figures 4 to 7 , Figure 4 This is a schematic diagram of the energy-concentrating ring structure in the embodiments of this application. Figure 5 yes Figure 4 The diagram shown is a top view of the energy-concentrating ring. Figure 6 yes Figure 5 The diagram shows a cross-sectional view of the energy-concentrating ring along the E-E' direction. Figure 7 yes Figure 6 A magnified diagram of region F in the middle.

[0092] In some embodiments, the energy-concentrating ring 11 includes a ring body 111 and a guide plate 112, with foot pieces 12 fixedly connected to the ring body 111, and an energy-concentrating disk 13 disposed around the outer periphery of the ring body 111. It is understood that the ring body 111 is annular and has the aforementioned cavity 11a, with the aforementioned guide cavity 13a formed between the ring body 111 and the energy-concentrating disk 13. The guide plate 112 is connected to the ring body 111 and located on the second side of the ring body 111. The guide plate 112 extends from the ring body 111 toward the outer side of the energy-concentrating disk 13 / energy-concentrating ring 11, and the guide plate 112 can guide the airflow within the guide cavity 13a toward the cookware. In this way, the preheated air in the guide cavity 13a can flow to the bottom of the pot and heat the pot when it flows out of the air outlet 13c, and the air flowing out of the air outlet 13c can be prevented from blowing directly onto the stove fire, thus preventing it from affecting the normal heating of the stove fire.

[0093] In some embodiments, a heat insulation layer may be provided inside the ring body 111 to improve the heat insulation effect of the ring body 111 and further reduce heat loss, thereby improving the thermal efficiency of the gas stove equipped with the energy-concentrating pot support 1.

[0094] In some embodiments, the ring body portion 111 includes an outer ring wall 113 and an inner ring wall 114 arranged opposite to each other. Both the outer ring wall 113 and the inner ring wall 114 are ring-shaped members, and the outer ring wall 113 surrounds the outer periphery of the inner ring wall 114. The outer ring wall 113 and the inner ring wall 114 are connected to form the cavity 11a.

[0095] Optionally, the outer ring wall 113 and the inner ring wall 114 can be separate components manufactured and installed separately, and fixedly connected by welding or other methods. The outer ring wall 113 and the inner ring wall 114 can also be set as an integral component, that is, the energy-concentrating ring 11 is a whole integral structure. For example, the tubular part can be bent and the two ends of the tubular part can be welded and fixed to form a ring structure.

[0096] In some embodiments, the outer annular wall 113 includes an inclined wall portion 1131 and an extended wall portion 1132. The inclined wall portion 1131 is inclined outward along the radial direction of the energy-concentrating disk 13, i.e., the outer circumference LO of the energy-concentrating disk 13, from the air inlet 13b towards the air outlet 13c. In other words, the inclined wall portion 1131 extends in an expanding (i.e., trumpet-shaped) direction from the air inlet 13b towards the air outlet 13c. The inclined wall portion 1131 is disposed around the center of the energy-concentrating disk 13 and forms the aforementioned air inlet 13b with the energy-concentrating disk 13. The extended wall portion 1132 is connected to the inclined wall portion 1131 and is located on the second side of the inclined wall portion 1131. The extended wall portion 1132 is converging towards the inner circumference of the energy-concentrating disk 13 relative to the inclined wall portion 1131. In this way, the portion of the energy-concentrating ring 11 facing the first side is smaller. When the energy-concentrating pot support 1 is installed on the gas stove, the energy-concentrating ring 11 can be closer to the burner and surround the outer perimeter of the burner, thereby confining the heat of the fire within a smaller space and reducing heat loss. Because the inclined wall portion 1131 expands and extends, while the extended wall portion 1132 is relatively converging towards the inclined wall portion 1131, the heat of the fire can be appropriately distributed within the space jointly defined by the inclined wall portion 1131 and the extended wall portion 1132 near the bottom of the pot. This ensures even heating of the bottom of the pot and prevents excessive heat concentration at the bottom, which could lead to uneven heating or even damage to the pot. Furthermore, because the extended wall portion 1132 is relatively converging towards the inclined wall portion 1131, when air flows out from the air outlet, the extended wall portion 1132 can act as a guide, directing the air towards the center of the energy-concentrating pot support 1, ensuring that the preheated air reaches the bottom of the pot to heat it.

[0097] It should be noted that the outer ring (LO) is the side where the outer space defined by the annular component is located, also known as the outer ring side. The inner ring (LI) is the side where the inner space defined by the annular component is located, also known as the inner ring side.

[0098] In some embodiments, the inclined wall portion 1131 includes a first sub-wall portion 11311 and a second sub-wall portion 11312. In the radial direction of the energy-concentrating disk 13 toward the outer ring of the energy-concentrating disk 13, the first sub-wall portion 11311 extends obliquely from the air inlet 13b toward the air outlet 13c; that is, the first sub-wall portion 11311 is trumpet-shaped and is arranged around the center of the energy-concentrating disk 13 to form the air inlet 13b with the energy-concentrating disk 13. The second sub-wall portion 11312 connects the first sub-wall portion 11311 and the extended wall portion 1132. Relative to the first sub-wall portion 11311, the second sub-wall portion 11312 extends obliquely toward the inner ring of the energy-concentrating disk 13, and is arranged around the center of the energy-concentrating disk 13. In other words, both the first sub-wall portion 11311 and the second sub-wall portion 11312 are annular wall portions.

[0099] It should be noted that in the direction from the air inlet 13b to the air outlet 13c, the second sub-wall portion 11312 expands and extends, that is, it is in the shape of a trumpet, but it is converging towards the center of the energy-concentrating disk 13 relative to the first sub-wall portion 11311. Thus, the distance between the first sub-wall portion 11311 and the energy-concentrating plate 13 is greater than the distance between the second sub-wall portion 11312 and the energy-concentrating plate 13. That is, the air inlet 13b of the guide cavity 13a is greater than the portion of the guide cavity 13a above the air inlet 13b. When a gas stove equipped with the energy-concentrating pot support 1 is used to heat a pot, the air in the guide cavity 13a flows upward. As the guide cavity 13a narrows upward, the air velocity increases and the air pressure gradually decreases, making it easier to form a pressure difference between the air inlet 13b and the air outlet 13c of the guide cavity 13a. This allows air from outside the energy-concentrating pot support 1 to enter the guide cavity 13a, thereby continuously allowing air from outside the energy-concentrating pot support 1 to enter the guide cavity 13a and recover waste heat.

[0100] In some embodiments, the included angle between the first sub-wall portion 11311 and the second sub-wall portion 11312 is α, and α satisfies the relationship: 140°≤α≤160°. For example, α can be 140°, 145°, 150°, 155°, 160° or other angle values ​​within this range. Within this range, when the air outside the energy-concentrating pot support 1 flows toward the center of the energy-concentrating pot support 1 to the first sub-wall portion 11311, the air can flow toward the air inlet 13b under the guiding action of the first sub-wall portion 11311. Furthermore, by satisfying this angle design in the direction from the air inlet 13b to the air outlet 13c, the guide cavity 13a can exhibit an appropriate tapering design, which helps the airflow entering the guide cavity 13a to generate a wall adhesion effect. That is, it enables the airflow to flow over the surfaces of the first sub-wall portion 11311 and the second sub-wall portion 11312, thereby generating convective heat transfer between the airflow and the surfaces of the first sub-wall portion 11311 and the second sub-wall portion 11312, and improving the heat absorption efficiency of the airflow on the energy-concentrating ring 11. When α < 140°, the tapering design of the guide cavity 13a is less effective, the airflow entering the guide cavity 13a is difficult to generate a wall adhesion effect, and the heat transfer efficiency between the airflow and the energy-concentrating ring 11 is low. When α > 160°, the second sub-wall portion 11312 expands outward significantly. When the airflow flows from the inlet 13b towards the outlet 13c, the angle of the outward flow is large. Due to the converging arrangement of the extension wall portion 1132, the angle of the airflow path is too large when the airflow flows from the second sub-wall portion 11312 to the extension wall portion 1132, which increases the wind resistance of the airflow in the guide cavity 13a. At the same time, the radial dimension of the side of the second sub-wall portion 11312 away from the first sub-wall portion 11311 is large, which is not conducive to the miniaturization design of the energy-concentrating pot support 1.

[0101] In some embodiments, the inclined wall portion 1131 further includes an arcuate wall portion 11313 connecting the first sub-wall portion 11311 and the second sub-wall portion 11312, the arcuate wall portion 11313 protruding outward toward the annular outer side of the energy-concentrating disk 13. The extending direction of the first sub-wall portion 11311 is parallel to the extending direction of the tangent of the arcuate wall portion 11313 at the position where it connects with the first sub-wall portion 11311. Similarly, the extending direction of the second sub-wall portion 11312 is parallel to the extending direction of the tangent of the arcuate wall portion 11313 at the position where it connects with the second sub-wall portion 11312. In other words, by setting the arc-shaped wall portion 11313, the transition between the first sub-wall portion 11311, the arc-shaped wall portion 11313, and the second sub-wall portion 11312 is smooth, which helps to reduce the airflow resistance in the guide cavity 13a and also helps to form a wall attachment effect on the surface of the first sub-wall portion 11311, the arc-shaped wall portion 11313, and the second sub-wall portion 11312, thereby improving the heat exchange efficiency.

[0102] In some embodiments, the extended wall portion 1132 is a curved wall portion that protrudes toward the energy-concentrating disk 13, and the extending direction of the inclined wall portion 1131 is parallel to the extending direction of the tangent at the connection point between the curved wall portion and the inclined wall portion. It is understood that since the second sub-wall portion 11312 connects the first sub-wall portion 11311 and the extended wall portion 1132, "the extending direction of the inclined wall portion 1131 is parallel to the extending direction of the tangent at the connection point between the curved wall portion and the inclined wall portion" specifically means that the extending direction of the second sub-wall portion 11312 is parallel to the extending direction of the tangent at the connection point between the curved wall portion and the second sub-wall portion 11312. This allows the outer ring wall 113 of the energy-concentrating ring body 11 to smoothly transition in the direction from the air inlet 13b to the air outlet 13c, reducing wind resistance in the airflow within the guide cavity 13a, reducing airflow turbulence within the guide cavity 13a, and thus reducing noise. At the same time, increasing the airflow velocity can improve the efficiency of heat recovery from the air to the energy-concentrating ring 11.

[0103] In some other embodiments, the extended wall portion 1132 may also be a straight plate wall portion, that is, the extended wall portion 1132 may extend in a straight line, and its extension direction forms an angle with the extension direction of the second sub-wall portion 11312. For example, the extended wall portion 1132 may extend along the axial direction of the energy-concentrating disk 13.

[0104] In some embodiments, the guide plate 112 includes an arc-shaped bend 1121, which is connected to the ring body portion 111 and located on the second side of the ring body portion 111. The arc-shaped bend 1121 bends toward the outer ring of the ring body portion 111 to form a groove 1121a with an opening toward the outer ring of the ring body portion 111. The opening of the groove 1121a also communicates with the air outlet 13c. This design, utilizing an arc-shaped bend, reduces the wind resistance of the guide plate 112 on the air flowing out of the air outlet 13c, allowing the air to flow smoothly to the bottom of the pot. At the same time, since the opening of the groove 1121a faces the outer side of the ring body 111 and is connected to the air outlet 13c, and the inner wall of the groove 1121a is arc-shaped, when foreign objects such as particles fall into the groove 1121a, the foreign objects can automatically detach from the groove 1121a under the action of gravity and enter the guide cavity 13a, and automatically fall along the guide cavity 13a to the outside of the energy-concentrating pot support 1, making it easy to clean.

[0105] In some embodiments, the tangent extending from the junction of the curved bend 1121 and the extended wall 1132 is parallel to the tangent extending from the junction of the extended wall 1132 and the curved bend 1121. That is, the smooth transition between the extended wall 1132 and the curved bend 1121 helps reduce wind resistance to the air flowing out of the air outlet 13c. Simultaneously, it also facilitates the automatic removal of impurities falling into the groove 1121a under gravity, allowing them to enter the guide cavity 13a along the extended wall 1132, and finally fall from the guide cavity 13a outside the energy-concentrating pot support 1.

[0106] In some embodiments, the baffle plate 112 further includes an air guide section 1122, which is connected to the side of the arc-shaped bend 1121 away from the ring body 111. The air guide section 1122 extends obliquely outward from the arc-shaped bend 1121 toward the outer edge of the ring body 111. During the use of the gas stove, because the bottom of the pot blocks the flame, the flame is distributed from the center of the energy-concentrating pot support 1 to the outer edge of the energy-concentrating pot support 1. However, most of the heat from the flame is still mainly distributed in the central area of ​​the energy-concentrating pot support 1, while the area near the periphery of the pot has less heat and a lower temperature. The air guide section 1122 extends obliquely outward toward the outer edge of the energy-concentrating ring 11, which can prevent the air flowing out of the gas outlet 13c from blowing directly onto the flame, thus preventing it from affecting the flame. At the same time, the air that has recovered the heat from the energy-concentrating pot support 1 flows from the gas outlet 13c toward the outer edge of the ring of the energy-concentrating pot support 1, which can heat the periphery of the bottom of the pot and improve the uniformity of heating the pot. Furthermore, the outward-distributed flames can come into contact with the secondary air flowing from the gas outlet to the outer ring of the energy-concentrating boiler support 1, so that the gas distributed in this area can be burned more completely, reducing the toxic and harmful gases produced due to incomplete combustion of gas.

[0107] In some embodiments, the foot piece 12 includes a foot piece body 121 and an abutment portion 122. The foot piece body 121 is fixedly connected to the ring body portion 111 and protrudes from the second side of the ring body portion 111, and the foot piece body 121 is used to support the cookware. The abutment portion 122 is connected to the foot piece body 121 and is located on the side of the foot piece body 121 outside the ring body portion 111. The abutment portion 122 abuts against the side of the guide plate 112 facing the energy-concentrating plate 13, so that the foot piece body 121 is fixed to the guide plate 112 through the abutment portion 122.

[0108] Understandably, to improve the fit between the abutment portion 122 and the guide plate 112, the surface of the abutment portion 122 facing the guide plate 112 can engage with the surface of the guide plate 112 facing the abutment portion 122. In other words, in the radial direction of the ring body portion 111, part of the surface of the abutment portion 122 facing the guide plate 112 is flat and fits against the guide portion 112, while another part of the surface of the abutment portion 122 is curved and fits against the arc-shaped bend portion 1121.

[0109] It should be noted that since the guide plate 112 is arranged around the center of the ring body 111, the surface of the guide plate 112 facing the contact portion 122 in the circumferential direction of the ring body 111 is a curved surface, i.e. an arc surface. Similarly, the surface of the contact portion 122 facing the guide plate 112 is an arc surface that matches it.

[0110] Please see also Figures 8 to 10 , Figure 8 yes Figure 4 The diagram shown is a side view of the energy-concentrating ring. Figure 9 yes Figure 1 Enlarged diagram of region A in the middle. Figure 10 yes Figure 4 A magnified diagram of region D in the middle.

[0111] In some embodiments, the foot piece 12 further includes a hook 123 connected to the foot piece body 121 or to the abutment portion 122. The hook 123 is located on the side of the foot piece body 121 outside the ring body portion 111. The hook 123 extends along the axial direction of the ring body portion 111 toward the energy-concentrating disk 13, and the energy-concentrating disk 13 has a clearance opening 13d corresponding to the hook 123. The hook 123 passes through the clearance opening 13d and extends into the flow guiding cavity 13a. The size of the portion of the hook 123 located in the flow guiding cavity 13a is larger than the size of the clearance opening 13d. In this way, the portion of the hook 123 in the flow guiding cavity 13a can form a stop engagement with the portion of the energy-concentrating disk 13 that forms the clearance opening 13d, so that the energy-concentrating disk 13 is hooked onto the hook 123, and the energy-concentrating disk 13 will not separate from the hook 123 unexpectedly.

[0112] In some embodiments, the hook 123 includes a connecting portion 1231 and an ear portion 1232. The connecting portion 1231 is connected to the foot plate body 121 or the abutting portion 122 and extends along the axial direction of the ring body portion 111 toward the energy-concentrating disk 13. The ear portion 1232 is connected to the end of the extension portion 1231 away from the foot plate body 121 and extends along the axial direction perpendicular to the ring body portion 111. The ear portion 1232 is used to form a stop engagement with the energy-concentrating disk 13 so that the energy-concentrating disk 13 is hooked onto the ear portion 1232.

[0113] In some embodiments, there may be two ears 1232, both of which are connected to the end of the connecting portion 1231 away from the foot body 121, and the two ears 1232 extend in a direction away from each other. In this way, the two ears 1232 can form at least two stop engagement points with the energy concentrating disk 13, thereby improving the connection strength and stability of the energy concentrating disk 13.

[0114] Please see also Figure 11 and Figure 12 , Figure 11 yes Figure 1 The diagram shown is an exploded view of the structure of the energy-concentrating cooker support. Figure 12 yes Figure 3 A magnified view of region C in the middle.

[0115] In some embodiments, the energy-concentrating disk 13 includes a first disk body 131 and a second disk body 132, both extending circumferentially along the ring body portion 111 and arranged opposite to each other. The first disk body 131 and the second disk body 132 are connected end-to-end to surround the outer periphery of the ring body portion 111. The connection point of the first disk body 131 and the second disk body 132 corresponds to two of the four oppositely arranged lugs 123. Furthermore, the first disk body 131 and the second disk body 132 have the aforementioned clearance opening 13d at their connection point corresponding to the two lugs 123. Thus, when installing the energy-concentrating disk 13, by aligning the first disk body 131 and the second disk body 132 from opposite directions, a portion of the lug 123 can enter the guide cavity 13a, facilitating the installation of the energy-concentrating disk 13. If the energy-concentrating plate 13 needs to be replaced due to deformation or damage, the energy-concentrating plate 13 can also be disassembled by separating the first plate body 131 and the second plate body 132, which facilitates the maintenance of the energy-concentrating pot support 1.

[0116] In some embodiments, the first disc 131 and the second disc 132 can be connected and fixed by means of snap-fit, screw-fit, plug-in, etc., and this application does not make specific limitations in this regard.

[0117] In some embodiments, the first disc 131 and the second disc 132 have the same structure and are symmetrically arranged on opposite sides of the ring body 111. The structure of the first disc 131 will be further described below using the first disc 131 as an example. The structure of the second disc 132 can be referred to below and will not be repeated.

[0118] In some embodiments, the first disc 131 includes an inclined plate portion 1311. Extending radially outward from the outer edge of the energy-concentrating ring 11 towards the air outlet 13c, the inclined plate portion 1311 is arranged around the outer periphery of the inclined wall portion 1131. That is, the inclined plate portion 1311 extends in an expanding manner from the air inlet 13b towards the air outlet 13c, forming a trumpet-shaped structure. The inclined plate portion 1311 and the inclined wall portion 1131 together form the aforementioned air inlet 13b.

[0119] In some embodiments, the extending direction of the inclined plate portion 1311 is parallel to the extending direction of the second sub-wall portion 11312, and in the axial direction of the energy-concentrating ring 11, the inclined plate portion 1311 is at least partially overlapped with both the first sub-wall portion 11311 and the second sub-wall portion 11312. In this case, the air inlet 13b is formed between the inclined plate portion 1311 and the first sub-wall portion 11311. Since the second sub-wall portion 11312 is converging toward the center of the energy-concentrating disk 13 relative to the first sub-wall portion 11311, the distance between the inclined plate portion 1311 and the first sub-wall portion 11311 in the radial direction of the energy-concentrating ring 11 is greater than the distance between the inclined plate portion 1311 and the second sub-wall portion 11312. That is, the size of the air inlet 13b in the radial direction of the energy-concentrating ring 11 is greater than the size of the remaining portion of the guide cavity 13a in the radial direction of the energy-concentrating ring 11.

[0120] In some embodiments, the energy-concentrating disk 13 further includes an extension plate portion 1312, which is connected to the inclined plate portion 1311 and located on the side of the inclined plate portion 1311 near the second side P2 of the energy-concentrating ring body 11. The extension plate portion 1312 is converging relative to the inclined plate portion 1311 toward the inner ring side L1 of the energy-concentrating ring body 11, and the extension plate portion 1312 is disposed around the outer periphery of the extension wall portion 1132 to form the aforementioned air outlet 13c. By converging the extension plate portion 1312, the size of the air outlet 13c can be made smaller than the size of the air inlet 13b, so that the guide cavity 13a forms a cavity that is narrow at the top and wide at the bottom. Meanwhile, since the extension plate 1312 is converging relative to the inclined plate 1311, when air flows out from the air outlet 13c, the extension plate 1312 can play a guiding role, so that the heat-absorbing air flows appropriately toward the center of the energy-concentrating pot support 1, ensuring that the heat-absorbing air can reach the bottom of the pot and be used to heat the pot.

[0121] In some embodiments, the extension plate portion 1312 is a curved plate portion that protrudes outward toward the outer side of the energy-concentrating ring 11, and the extension direction of the inclined plate portion 1311 is parallel to the extension direction of the tangent at the connection point between the curved plate portion and the inclined plate portion 1311. This allows the energy-concentrating disk 13 to smoothly transition toward the inner wall of the energy-concentrating ring 11, helping to reduce wind resistance when air flows in the guide cavity 13a, reducing turbulence in the airflow inside the guide cavity 13a, and thus reducing noise. Simultaneously, increasing the airflow velocity can improve the efficiency of heat recovery from the energy-concentrating ring 11.

[0122] It is understandable that the clearance 13d is provided on the extension plate portion 1312.

[0123] Please see also Figure 13 and Figure 14 , Figure 13 This is a top view of the gas stove in an embodiment of this application. Figure 14 yes Figure 13 The diagram shows a cross-sectional view of the gas stove along the G-G' direction.

[0124] A second aspect of this application provides a gas stove 2, including the energy-concentrating pot support 1 described in any of the above embodiments.

[0125] In some embodiments, the gas stove 2 includes a housing 21, which has a mounting cavity 21a. The mounting cavity 21a can be used to accommodate some components of the gas stove 2, such as a control panel, a display panel, and part of the gas pipe.

[0126] For example, the housing 21 can be a square shell shape, having a bottom 211 and a side wall portion 212 provided along the edge of the bottom 211, the bottom 211 and the side wall portion 212 surrounding the aforementioned mounting cavity 21a.

[0127] In some embodiments, the gas stove 2 further includes a panel 22, which covers the housing 21 and has a clearance hole 22a communicating with the mounting cavity 21a. The panel 22 can be a flat plate-shaped member, which covers the mounting cavity 21a by covering the housing 21, while the clearance hole 22a can expose part of the mounting cavity 21a so that some components located in the mounting cavity 21a can be exposed to the outside of the gas stove 2 through the clearance hole 22a.

[0128] Understandably, the panel 22 may be equipped with knobs or buttons for adjusting the flame size and / or changing the flame combustion mode, as well as buttons for ignition.

[0129] In some embodiments, the gas stove 2 further includes a burner assembly 23, which is disposed in the housing 21, with a portion of the burner assembly 23 located in the mounting cavity 21a and another portion protruding outside the mounting cavity 21a through a clearance hole 22a. During the operation of the gas stove 2, the flame is located at the burner assembly 23, and cookware can be placed on the burner assembly 23 and heated by the flame.

[0130] In some embodiments, the burner assembly 23 includes a burner 231, which is fixed to the housing 21. A portion of the burner 231 is located in the mounting cavity 21a, and another portion protrudes outside the mounting cavity 21a through the first clearance hole 22a. It is understood that the burner 231 is fixedly connected to the bottom 211 of the housing 21 to fix the position of the burner 231.

[0131] For example, the burner head 231 is configured to be circular. A circular burner head can make the flame distribution more even, thereby heating the cookware more evenly and avoiding excessive heat concentration that could burn the cookware.

[0132] Understandably, the energy-concentrating pot support 1 is mounted on the panel 22 and arranged corresponding to the clearance hole 22a, surrounding the outer periphery of the burner head 231. In this way, during the use of the gas stove 2, the energy-concentrating pot support 1 can reduce heat loss from the burner head 231. Simultaneously, the guide cavity 13a of the energy-concentrating pot support 1 can create natural convection to recover heat from the support 1 and use it to heat the cookware, while also supplementing the burner with preheated secondary air. This improves the combustion efficiency of the gas, thereby increasing the thermal efficiency of the gas stove 2.

[0133] The above provides a detailed description of the energy-concentrating pot support and gas stove provided in the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the idea of ​​this utility model. There may be changes in the specific implementation and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
