Detailed Description

The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

The inventor finds that the pot support has three main functions: firstly, flame and high-temperature flue gas generated by combustion of fuel gas of a burner are restrained to flow closely to the wall surface of a cooker, and heat transfer to the cooker is enhanced; secondly, heat dissipation of flame and high-temperature flue gas to the surrounding environment is reduced; thirdly, the secondary air is organized, the secondary air is controlled to be contacted with the fuel gas, so that the fuel gas is combusted fully as much as possible, and further the heat loss of the discharged smoke is reduced. However, part of the heat energy carried by the flame and the high-temperature flue gas is inevitably transferred to the pot support, and is radiated to the periphery through the pot support, and the higher the radiating rate of the part of heat energy is, the lower the heat energy is utilized, so that the heat efficiency of the kitchen range is reduced. Based on the above, the embodiment of the application provides a pot support and a cooker, which can reduce the heat transfer rate of the pot support so as to improve the heat efficiency of the cooker.

Referring to fig. 1, a schematic structural diagram of a pan support 10 according to an embodiment of the present application is provided, where the pan support 10 includes a pan support body 30, and the pan support body 30 is annular in shape and has a central through hole 113, and the central through hole 113 is used for accommodating a burner of a stove.

The pan support 10 further includes pan legs 20, and the pan legs 20 are disposed on one side of the pan support body 30 in an axial direction H of the pan support body 30 and are used for carrying a pan. When the cooker is carried on the cooker support 20, the cooker is arranged corresponding to the central through hole 113 of the cooker support body 30, the burner, the cooker support 10 and the cooker form a combustion space, the combustion space comprises the central through hole 113 of the cooker support body 30, the burner is arranged at the central through hole 113, primary air is provided by a nozzle of the burner, and flame and smoke are generated by mixing combustion of the primary air and fuel gas so as to heat the cooker. The pan support 20 has a carrying surface 21 for carrying a pan, at least part of the carrying surface 21 may be a plane parallel to the horizontal plane for placing the pan.

The pot support legs 20 separate the pot from the pot holder body 30, the combustion space further comprises an air passing space formed between the bottom wall of the pot and the pot holder body 30, and smoke generated during combustion of the burner can be discharged out of the combustion space through the air passing space, so that a heat flow path flowing from the central through hole 113 to the air passing space is formed. The burner burns fuel gas at the center through hole 113 to generate flame and flue gas to heat the cooker, the annular cooker rack main body 30 can separate high-temperature flame generated by the burner from the external environment, the influence of external low-temperature airflow on the flame and the loss of combustion heat are reduced, and meanwhile, the high-temperature flue gas can stay in a combustion space for a longer time, so that the high-temperature flue gas has enough time to fully exchange heat with the bottom wall of the cooker, and the heat exchange efficiency and the overall heat efficiency of the burner are improved.

In order to further improve the combustion efficiency, secondary air is also required to be provided for the fuel gas, so that a space communicated with the combustion space is also required to be arranged, and the secondary air enters the combustion space through the space and then contacts with the fuel gas. For example, the pan support 10 further includes a supporting leg 40, where the supporting leg 40 is disposed on a side of the pan support body 30 away from the pan support leg 20, and the supporting leg 40 is used for being placed on other structural components, for example, on a water pan of a cooking bench or a structural component such as a cooking bench support, so as to space the pan support body 30 from other structural components, and a space between the pan support body 30 and other structural components forms a space. The flame and the flue gas flow in the combustion space to heat the cooker and are in contact with the cooker frame main body 30, so that part of heat energy is transferred to the cooker frame main body 10, the cooker frame main body 30 is a part mainly participating in defining the combustion space, a large amount of heat transferred by the flame and the flue gas in the combustion space is transferred to the space and the environment space where the cooker frame main body 10 is positioned, and when the heat transfer rate of the cooker frame main body 30 is higher, the heat loss caused by heat transfer of the cooker frame main body 30 is larger, and the heat efficiency of gas combustion is lower.

The embodiment of the application provides a pot rack body 30 with a pot rack shell 100, wherein a central through hole 113 is defined by the pot rack shell 100, as shown in fig. 2, a first heat insulation cavity 112 is arranged in the pot rack shell 100, air is arranged in the first heat insulation cavity 112, the heat conductivity coefficient of the air is lower than that of the pot rack shell 100, and the heat of a combustion space can be prevented from being dissipated outwards by the first heat insulation cavity 112, so that heat energy loss is reduced, and the heat efficiency of gas combustion is improved. Optionally, the pan frame housing 100 in the embodiment of the present application is made of metal, and the pan frame main body 30 still has good structural stability under the high temperature condition, so as to provide support for pans with larger mass. Of course, the material of the pan support 10 in the embodiment of the application is not limited to metal, and any material with good support structure strength under high temperature condition is suitable for the application.

As shown in fig. 3, the pot rack main body 30 further includes a heat insulation core 200, the heat insulation core 200 is disposed in the first heat insulation cavity 112, wherein the heat conductivity coefficient of the pot rack housing 100 is β1, the heat conductivity coefficient of the heat insulation core 200 is β2, β2< β1, and both air in the first heat insulation cavity 112 and the heat insulation core 200 can block heat transfer, so that heat emitted from the pot rack main body 30 to the space and the environment space where the pot rack 10 is located is reduced. The heat conductivity of both the air in the first heat insulation cavity 112 and the heat insulation core 200 is low relative to the heat conductivity of the pot rack housing 100, and the heat dissipation rate of both the air in the first heat insulation cavity 112 and the heat insulation core 200 is also low, so that both the air in the first heat insulation cavity 112 and the heat insulation core 200 can also have heat insulation effect, and heat loss is further reduced. In addition, compared with the first insulating cavity 112 without the insulating core 200, the embodiment of the application sets the insulating core 200 in the first insulating cavity 112, and can also block the airflow caused by heat energy exchange, and the slower the airflow or the smaller the flow range, the better the effect of blocking the heat flow exchange. As shown in fig. 4, when the heat insulation core 200 is not disposed in the first heat insulation cavity 112 in the pot rack housing 100, the heat energy flow in the first heat insulation cavity 112 is schematically shown, and when the heat insulation core 200 is disposed in the first heat insulation cavity 112, the heat energy flow can be effectively blocked, so that the heat energy flow rate is reduced, and the heat dissipation capacity is reduced.

It can be appreciated that when the heat energy is transferred in the medium with the same heat conductivity coefficient, the transfer rate is unchanged, so when the heat conductivity coefficient of the wok stand shell 100 is higher, the heat transfer rate of the heat in the wok stand shell 100 is also faster, and the heat transfer is smooth, based on the heat transfer rate, the wok stand shell 100 is provided with at least one heat insulation opening 114 communicated with the first heat insulation cavity 112, and the heat insulation opening 114 increases the obstruction for the wok stand shell 100 to transfer the heat energy, so that the heat transfer rate of the wok stand shell 100 to transfer the heat energy is reduced. In addition to the heat transfer rate being affected by the thermal conductivity, the heat transfer area will also affect the heat transfer rate, and in the case where the wok stand body 30 is also required to confine flames and high temperature flue gas, the relative surface area of the wok stand body 30 will be set larger, and the large relative surface area results in a greater heat dissipation rate of the wok stand body 30, reducing the relative surface area of the wok stand housing 100 through the heat insulation opening 114, thereby reducing the heat dissipation rate. Although the existence of the heat insulation opening 114 enables the first heat insulation cavity 112 to be communicated with the environment outside the pot rack shell 100 for airflow, the heat insulation core 200 is arranged in the first heat insulation cavity 112 and can block airflow, so that airflow in the first heat insulation cavity 112 is stable, and heat loss caused by airflow is prevented.

Therefore, in the present application, when the heat insulation core 200 is disposed in the first heat insulation cavity 112 to perform heat insulation and heat preservation, the sealing performance of the first heat insulation cavity 112 is broken, and the heat loss is not limited to be reduced by adopting the heat insulation mode of the sealing cavity, and the heat insulation core 200 and the heat insulation opening 114 cooperate together, so that the heat diffused out through the pot frame main body 30 can be reduced to a greater extent, and the heat efficiency of the fuel gas is effectively improved.

In the embodiment of the application, the heat insulation core 200 is annular as a whole, and the heat insulation core 200 and the pot rack housing 100 are coaxially arranged, so that the heat transfer of the whole pot rack main body 30 is uniform. The heat insulation core 200 is filled in at least part of the space of the first heat insulation cavity 112, for example, the heat insulation core 200 is filled in part of the space of the first heat insulation cavity 112, as shown in fig. 3, two outer surfaces of the heat insulation core 200, which are oppositely arranged in the axial direction H of the wok stand main body 30, are in fit with part of the wall surface of the first heat insulation cavity 112 defined by the wok stand shell 100, and two outer surfaces of the heat insulation core 200, which are oppositely arranged in the radial direction of the wok stand main body 30, are spaced apart from part of the wall surface of the first heat insulation cavity 112 defined by the wok stand shell 100; or the heat-insulating core 200 fills all the cavities of the first heat-insulating cavity 112, at this time, all the outer surfaces of the heat-insulating core 200 are attached to all the walls of the first heat-insulating cavity 112 defined by the pot frame housing 100 (it is understood that, due to the limitation of the machining precision, a gap is inevitably present between the heat-insulating core 200 and the walls of the first heat-insulating cavity 112, and in this case, it is considered that the heat-insulating core 200 fills all the cavities of the first heat-insulating cavity 112, regardless of the machining gap due to the machining precision). The present application is not limited to this, and the amount of the heat insulating core 200 filled in the first heat insulating cavity 112 can be selected according to practical needs. The insulating core 200 is coupled to the insulating housing 210 to define the position of the insulating core 200 relative to the integrated wok stand housing 100.

As shown in fig. 5, the heat insulation opening 114 provided in the wok stand housing 100 may be provided in an edge region of the heat insulation housing 210 (i.e., the opening a1 shown in fig. 5), or the heat insulation opening 114 provided in the wok stand housing 100 may be provided in a middle region of the heat insulation housing 210 (i.e., the opening b shown in fig. 5). Wherein, the orientation of the heat insulation opening 114 is perpendicular to the plane of the heat insulation opening 114.

Alternatively, referring to fig. 2 again, the pan frame housing 100 may be an integral pan frame housing 100 formed by integral injection molding, bending or welding, and the integral pan frame housing 100 defines the first heat-insulating cavity 112.

Alternatively, the wok stand housing 100 may include a plurality of plates with edges of adjacent plates connected or spaced apart to define the first insulated cavity 112 and edges of at least one adjacent plate spaced apart to define an insulated opening 114, wherein the insulated core 200 is connected to the plates to define the position of the insulated core 200 relative to the integrated wok stand housing 100. When any two adjacent plate bodies are arranged at intervals, the heat insulation opening 114 is an annular opening arranged around the central through hole 113 of the pot frame shell 100, and each plate body is connected with the heat insulation core 200, and the heat insulation core 200 is used for providing support for a plurality of plate bodies so as to limit the relative positions of each plate body and the heat insulation core 200, so that baffle openings are formed at the edges of the two adjacent plate bodies.

As shown in fig. 6, the wok stand case 100 includes two plates, which together define the first heat insulation cavity 112, and specifically, the wok stand case 100 includes a first plate 110 and a second plate 120, wherein the first plate 110 and the second plate 120 are disposed opposite to each other in a vertical direction, the first plate 110 is connected to the heat insulation core 200, the second plate 120 surrounds the first plate 110 to define the first heat insulation cavity 112, and an outer edge of the first plate 110 and an outer edge of the second plate 120 are disposed at intervals and define a heat insulation opening 114, and an inner edge of the first plate 110 and an inner edge of the second plate 120 are disposed at intervals and define a heat insulation opening 114, that is, in this embodiment, the first plate 110 and the second plate 120 are spaced apart in the vertical direction by a supporting action of the heat insulation core 200, and the first plate 110 and the second plate 120 are each formed with a heat insulation opening 114 at positions corresponding to an inner side and an outer side of the heat insulation core 200.

Because, in the actual use process, the first plate 110 is closer to the cookware placed on the pan support 20 than the second plate 120, and the cookware and the pan support 10 fully contact the high-temperature flue gas generated in the combustion process in the heating process, and also flow through the surface of the first plate 110 in the process of discharging the high-temperature flue gas out of the pan support 10, the heat transfer between the cookware and the pan support 20 and the direct heating of the high-temperature flue gas cause the temperature of the first plate 110 to be higher than the temperature of the second plate 120, and the heat insulation core 200 greatly weakens the heat transfer condition between the first plate 110 and the second plate 120 under the condition that the first plate 110 and the second plate 120 are spaced in the vertical direction, so that the heat generated in the combustion process can be reduced from the transmission path of the first plate 110 to the second plate 120 to the environment, and the heat efficiency of the gas stove can be improved.

In other embodiments, the inner edge of the first plate 110 and the inner edge of the second plate 120 may be spaced apart to define a heat insulation opening 114, and the outer edge of the first plate 110 and the outer edge of the second plate 120 are connected; or the inner edge of the first plate 110 and the inner edge of the second plate 120 are connected, and the outer edge of the first plate 110 and the outer edge of the second plate 120 are spaced apart and define a heat insulation opening 114. Wherein, the middle area of any one of the first plate body 110 and the second plate body 120 is further opened with a heat insulation opening 114 communicated with the first heat insulation cavity 112 to further reduce the heat transfer area.

The foregoing is merely exemplary, and in other embodiments, the wok stand housing 100 may include a greater number of panels, e.g., the wok stand housing 100 includes three or four or more panels, and the plurality of panels defines two or three or more first insulated chambers 112, with at least one of the first insulated chambers 112 having an insulated core 200 disposed therein.

Further, the plurality of plate bodies further define at least two heat insulation openings 114, wherein one heat insulation opening 114 is far away from the central through hole 113 of the heat insulation shell 210 (i.e. the opening a1 shown in fig. 6), the other heat insulation opening 114 is close to the central through hole 113 of the heat insulation shell 210 (i.e. the opening a2 shown in fig. 6), the plate edges of the two heat insulation openings 114 are arranged at intervals, and the heat insulation core 200 is radially arranged between the two heat insulation openings 114 in the pot frame main body 30, so that the heat energy transmission can be better blocked.

Regarding the docking manner of the multiple plate bodies, the multiple plate bodies may be specifically selected according to actual needs, for example, the multiple plate bodies are stacked along the axial direction H of the pan frame body 30, at least two of the multiple plate bodies surround to define the first heat insulation cavity 112, for example, as shown in fig. 6, the pan leg 20 is disposed on the first plate body 110, the first plate body 110 and the second plate body 120 are stacked along the axial direction H of the pan frame body 30 and define the first heat insulation cavity 112, the inner edge of the first plate body 110 and the inner edge of the second plate body 120 define one heat insulation opening 114 (i.e., the opening a2 shown in fig. 6) adjacent to the central through hole 113 of the pan frame body 100, the outer edge of the first plate body 110 and the outer edge of the second plate body 120 define the other heat insulation opening 114 (i.e., the opening a1 shown in fig. 6) distant from the central through hole 113 of the pan frame body 100, and the heat insulation core 200 is disposed between the two heat insulation openings 114 in the radial direction of the pan frame body 30; or the pan frame housing 100 includes a first plate 110 and two third plates (not shown in the figure), the pan frame 10 is disposed on the first plate 110, the two third plates are disposed on one side of the first plate 110 facing away from the pan frame 10 in an axial direction H of the pan frame main body 30, the first plate 110 and the two third plates together define a first heat insulation cavity 112, an inner edge of the first plate 110 and one of the third plates define one heat insulation opening 114 adjacent to a central through hole 113 of the pan frame housing 100, an outer edge of the first plate 110 and the other third plate define another heat insulation opening 114 distant from the central through hole 113 of the pan frame housing 100, and in a radial direction of the pan frame main body 30, the two third plates are disposed at intervals and define a heat insulation opening 114 (not shown in the figure) with the opening facing away from the pan support leg 20.

The pot holder housing 100 has a guide surface 111, the pot support 20 is disposed on the guide surface 111, the space between the guide surface 111 and the bottom wall surface of the pot forms an air passing space, the guide surface 111 is a concave surface curved to a side far away from the pot support 20, so as to limit that flames and smoke can stay in the combustion space for a longer time. As shown in fig. 6, the pot holder case 100 has a first inner turn 1101 and a second inner turn 1201 extending opposite to each other, and the second inner turn 1201 extends toward a side where the bearing surface 21 of the pot leg 20 is located, and the pot holder case 100 also has a first turn 1102 and a second turn 1202 extending opposite to each other, and the second turn 1202 extends toward a side where the bearing surface 21 is located, and the flow guiding surface 111 is located between the first inner turn 1101 and the first turn 1102 in a radial direction of the pot holder body 30. When the wok stand housing 100 includes the first plate body 110 and the second plate body 120, the first plate body 110 has a first inner flange 1101, a first outer flange 1102, and a flow guiding surface 111, and the second plate body 120 has a second inner flange 1201 and a second outer flange 1202.

The edges of the first inner turn 1101 are spaced from the edges of the second inner turn 1201 to define a thermally insulated opening 114, the thermally insulated opening 114 being adjacent the central through bore 113, the first inner turn 1101 and the second inner turn 1201 being capable of blocking the ingress of flame, smoke, oil and gas impurities into the first thermally insulated cavity 112, thereby blocking the flow of air due to the ingress of impurities into the first thermally insulated cavity 112.

The flame and the flue gas generated by the combustion of the fuel gas flow towards one side where the pot support 20 is located and are blocked by the pot, and then the direction of the flame and the flue gas is changed to diffuse to the periphery, as shown in fig. 6, in the radial direction of the pot rack main body 30, the distance from the edge of the first inner flange 1101 to the central axis of the pot rack housing 100 is L1, the distance from the edge of the second inner flange 1201 to the central axis of the pot rack housing 100 is L2, and L1< L2, so that the heat insulation opening 114 at the first inner flange 1101 is opened at one side facing away from the pot support 20, and the probability of the flame and the flue gas entering the first heat insulation cavity 112 is reduced.

Further, in the radial direction of the pot holder main body 30, the first inner turned edge 1101 and the second inner turned edge 1201 are partially overlapped, so that the first inner turned edge 1101 and the second inner turned edge 1201 form a back-off structure, and the first inner turned edge 1101 can more effectively block flame and smoke from entering the first heat insulation cavity 112.

As shown in fig. 6, the edges of the first turn-up 1102 are spaced from the edges of the second turn-up 1202 to define a thermally insulated opening 114, thus reducing the ingress of smoke and oil gas from the first turn-up 1102 into the first thermally insulated cavity 112. Further, the distance from the first outward flange 1102 to the central axis of the wok stand shell 100 is greater than the distance from the second outward flange 1202 to the central axis of the wok stand shell 100, and in the radial direction of the wok stand body 30, the first outward flange 1102 and the second outward flange 1202 are partially overlapped, so that the flue gas and oil gas are further prevented from entering the first heat insulation cavity 112 from the first outward flange 1102.

In other embodiments, a first inside turn 1101 and a second inside turn 1201 connection may be provided; alternatively, a first turn-up 1102 and a second turn-up 1202 may be provided.

The second heat insulation cavity 201 is a closed cavity, and blocks gas exchange in the first heat insulation cavity 112 and the second heat insulation cavity 201, so that the heat insulation effect of the heat insulation core 200 is improved. When the number of the second insulation chambers 201 is one, the second compartment is in the form of an annular chamber arranged coaxially with the insulation core 200. When the number of the second heat insulating chambers 201 is plural, the plural second heat insulating chambers 201 are disposed at intervals around the circumference of the center through hole 113; or a plurality of second heat insulation chambers 201 are arranged at intervals in the axial direction H of the pot holder body 30. Wherein the interval is set such that two adjacent second heat insulating chambers 201 are not communicated with each other.

Alternatively, each flow blocking portion 220 has a ring shape disposed around the circumference of the central through hole 113; or the adjacent two flow blocking parts 220 are arranged at intervals in the circumferential direction of the central through hole 113 and have equal intervals, and the adjacent two flow blocking parts 220 are arranged at intervals in the radial direction of the pot rack main body 30 and have equal intervals. In other embodiments, the plurality of flow blocking portions 220 may be arranged in a disordered manner, and the circumferential spacing between two adjacent flow blocking portions 220 is different in the pot rack body 30, and the radial spacing between two adjacent flow blocking portions 220 is also different in the pot rack body 30.
