Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments and features of the embodiments described below can be combined with each other without conflict.

Referring to fig. 1 to 3, the present embodiment provides a wok stand assembly, which includes a pan body 100 and a leg piece 200 disposed on the pan body 100; at least part of the disc body 100 adopts a multi-layer composite structure, and the multi-layer composite structure comprises heat insulation layers 10 positioned at two opposite outer sides and a middle layer 20 positioned in the middle; the thermal conductivity of the intermediate layer 20 is higher or lower than that of the insulating layer 10.

According to the wok stand assembly provided by the embodiment, when the heat-conducting property of the middle layer 20 is higher than that of the heat-insulating layer 10, the heat-insulating layer 10 can reduce the heat transferred downwards, the middle layer 20 can enable the heat-insulating layers 10 on the two outer sides to be quickly heated to be consistent, the heat is heated relatively uniformly, the local temperature is prevented from being too high, the problem that the wok stand assembly is easy to deform at high temperature can be relieved, and the emission of nitrogen oxides is reduced; meanwhile, the multilayer composite structure can form dynamic balance of heat insulation and heat storage, and the disc body 100 after heat collection can perform heat radiation to the combustion chamber 40, so that the temperature of the combustion chamber 40 is increased, and the heat efficiency is improved. When the heat-conducting property of the middle layer 20 is lower than that of the heat-insulating layer 10, the middle layer 20 has smaller heat conductivity, so that the heat conduction is greatly reduced, the heat loss of the combustion chamber 40 is reduced, the temperature of flame and smoke is higher, and the heat efficiency is improved.

Wherein the combustion chamber 40 is a region of a central portion of the wok stand assembly; the material of the insulation layer 10 may be stainless steel.

Specifically, the intermediate layer 20 may be a heat storage intermediate layer having high heat conductivity and capable of storing heat, and the material of the heat storage intermediate layer may be at least copper, aluminum, zinc, or iron.

Illustratively, when the material of the thermal insulation layer 10 is stainless steel and the material of the middle layer is aluminum, the upper layer is made of stainless steel, which has poor thermal conductivity and can reduce the amount of heat transferred downwards, but because the thermal insulation layer is closer to the flame, the thermal radiation and the thermal conduction are both more, and therefore a part of the heat is still transferred downwards; when the material of intermediate level 20 was aluminium, it contacted with the upper strata, and aluminium is compared and is had better heat conductivility in stainless steel, therefore intermediate level 20 is in order to realize the high efficiency transmission of heat, rapid heating up, and it is even to guarantee that multilayer composite structure is heated, prevents that local temperature is too high, alleviates pot frame yielding problem under the high temperature effectively, is favorable to reducing nitrogen oxide NOx's emission.

Furthermore, the middle layer made of aluminum can absorb heat which is not blocked by the upper layer and store the heat, the lower layer arranged below the middle layer is made of stainless steel, and the downward transmission heat of the multilayer composite structure is further reduced, so that the dynamic balance of heat insulation and heat storage can be formed through the structure.

The intermediate layer 20 may be a heat-insulating intermediate layer with low thermal conductivity and capable of performing a heat-insulating function, and may be made of at least high-temperature-resistant aerogel, ceramic, or glass fiber.

Illustratively, when the material of the thermal insulation layer 10 is stainless steel and the material of the intermediate layer is aerogel, since aerogel has extremely high porosity and pore size, the network structure greatly increases the passage of heat in the aerogel, and thus has extremely low thermal conductivity (even lower than air), and is a thermal insulation material. Compared with the upper layer and the lower layer which are insulated, the middle layer 20 greatly reduces heat conduction, thereby reducing the heat loss of the combustion cavity 40, leading the temperature of flame and smoke to be higher and improving the heat efficiency.

Referring to fig. 1 to 3, the disc body 100 employs the aforementioned multilayer composite structure.

Compared with the traditional single-layer plate, the plate body 100 adopts the multi-layer composite structure, and dynamic balance of heat insulation and heat storage can be formed by means of the structure, so that heat radiation is carried out on the pot frame and the combustion cavity 40 upwards, the temperature of the combustion cavity 40 is increased, the temperature of flame and smoke is higher, meanwhile, the heat exchange between the pot frame and the pot bottom is enhanced, and the heat efficiency is improved; in addition, since the tray body 100 can maintain a high constant temperature, the secondary air is preheated when entering the burner from below the tray body 100, thereby further improving the heat efficiency.

Further, the leg pieces 200 are inserted into the tray body 100; wherein, the one end of foot piece 200 is used for placing on the cooking utensils panel, and the other end can support the pan.

Referring to fig. 4 to 7, the tray body 100 includes an upper tray 110 and a lower tray 120, the upper tray 110 and the lower tray 120 enclosing a closed cavity 30; the upper tray 110 adopts a multi-layer composite structure; the lower tray 120 has a single-layered tray body structure made of a heat insulating material.

Be stagnant air (or vacuum) in the airtight cavity 30, its heat conductivility is worse, therefore the heat assembles all the time at the dish body 100 to keep higher constant temperature, the dish body 100 of invariable high temperature can carry out the heat radiation to burning chamber 40 and pan, increases the temperature in burning chamber 40 on the one hand, makes the temperature of flame and flue gas higher, and the increasing thermal efficiency, on the other hand strengthens the heat exchange of pot frame subassembly and pan bottom, increasing thermal efficiency.

Further, referring to fig. 8 to 10, the plate body 100 further includes an intermediate plate 130 disposed between the upper plate 110 and the lower plate 120, and the intermediate plate 130 divides the sealed cavity 30 into an upper sealed cavity 31 and a lower sealed cavity 32 disposed up and down, so that the heat transferred downward from the pot rack can be further reduced by providing two sealed cavities as compared with providing only one sealed cavity 30.

The intermediate tray 130 has a single-layered tray structure and is made of a heat insulating material.

In the embodiment of providing the upper disc 110 and the lower disc 120, the leg pieces 200 are disposed on the upper surface of the upper disc 110, and the leg pieces 200 are disposed in a plurality of groups and are circumferentially spaced apart.

Further, the bottom surface of the lower tray 120 is provided with supporting legs 300 corresponding to the number of the leg pieces 200.

Referring to fig. 11 and 12, the leg piece 200 employs a composite leg piece in conformity with the multi-layer composite structure of the disc body 100; wherein, in compound foot piece, the top edge of intermediate level 20 is less than the top edge of insulating layer 10 to make the three form groove structure, the reducible area of contact of foot piece 200 and the bottom of a boiler of this groove structure, thereby reduced the bottom of a boiler to the heat-conduction of pot frame, be favorable to the promotion of thermal efficiency.

The present embodiment also provides a gas hob including the pot rack assembly of the previous embodiment. The gas cooker provided by the embodiment comprises the pot frame assembly, so that the technical advantages and effects which can be achieved by the gas cooker also comprise the technical advantages and effects which can be achieved by the pot frame assembly, and are not described again.
