Description

Technical Field

[0001] The invention relates to the technical field of gas stoves, in particular to a double-insulated cavity pot rack. Background Art

[0002] In current gas burner stoves, a pot rack is usually installed on the burner so that the burner is ignited and burned in the pot rack. The pot rack can support the pot and also focus energy for the burning flame.

[0003] However, traditional energy-concentrating pot racks all have an insulating cavity inside, and at the same time, the upper surface layer is an arc-shaped structure. The inner surface of the arc-shaped structure is prone to form vortices, so that when the burner burns in the pot rack, the heat is concentrated at the bottom of the pot, thereby improving the combustion efficiency. However, since the pot racks are all made of metal, there is no structure to block and dissipate heat for the pot racks, and the heat is still dissipated from the inside to the outside. The heat utilization rate needs to be further improved. Summary of the invention

[0004] In order to overcome the defects of the prior art, the present invention provides a double-insulated cavity pot rack to solve the problems in the prior art.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a double-insulated cavity pot stand, comprising an outer plate and an inner plate, wherein the middle of the outer plate and the inner plate are both provided with a burner combustion hole, a first insulation cavity is arranged in the outer plate, a second insulation cavity is arranged in the inner plate, a gap is arranged between the outer plate and the inner plate, and the gap is connected to the burner combustion hole.

[0006] The beneficial effect of the present invention is that during the combustion process of the burner in the combustion hole of the burner, the outer plate and the inner plate are respectively isolated from dissipating heat to the outside through the first insulation cavity and the second insulation cavity. At the same time, the gap formed between the outer plate and the inner plate can allow secondary air to enter the combustion hole of the burner, so that the combustion efficiency of the burner is higher. In addition, during the flow replenishment process of the secondary air, the metal heat transfer between the outer plate and the inner plate is blocked and cooled, and the secondary air can be preheated to further reduce the heat dissipated outward from the heat transfer of the pot rack itself, thereby greatly improving the energy gathering effect.

[0007] Furthermore, the outer disk covers and wraps around the outer side of the inner disk in the circumferential direction.

[0008] With the above further structure, the heat can be better gathered in the inner disk to prevent the heat from being dissipated outwards.

[0009] Furthermore, the outer disk includes a first bottom ring seat and a first top ring, and first bending sections are provided on both sides of the first top ring. The first bending sections on both sides are respectively sealed and covered on both sides of the first bottom ring seat, and the first thermal insulation cavity is formed between the first bottom ring seat and the first top ring.

[0010] After adopting the above-mentioned further structure, the first heat insulation cavity is better formed between the first bottom ring seat and the first top ring, and the first top ring can be positioned to place the inner disk to form a double-layer heat insulation effect, thereby improving the heat energy gathering effect.

[0011] Furthermore, the cross-sectional side projection of the first top ring is L-shaped, and the inner disk is positioned and mounted on the upper end of the first top ring.

[0012] With the above further structure, the first heat insulating cavity can better cover the outer side of the inner plate, thus further preventing heat dissipation.

[0013] Furthermore, the inner disk includes a second bottom ring seat and a second top ring, the cross-sectional side projection of the second bottom ring seat is L-shaped, the second bottom ring seat is suspended at the upper end of the first top ring, the second bottom ring seat and the inner side of the second top ring are sealed and connected, the outer side of the second top ring is provided with a second bending section, and the second bending section is sealingly mounted on the outer side of the second bottom ring seat.

[0014] After adopting the above-mentioned further structure, the second bottom ring seat cooperates better with the first top ring, with a higher coverage, and the second insulation cavity can improve the insulation effect of the first layer. With the cooperation of the outer plate, the heat dissipated from the inner plate is prevented from further dissipating, so that the heat is better gathered at the bottom of the pot.

[0015] Furthermore, the outer wall of the outer side of the second bottom ring seat and the outer wall of the first top ring form an air supplement input channel, the upper end of the air supplement input channel is an opening, and an air supplement output channel is formed between the lower end surface of the second bottom ring seat and the upper end surface of the first top ring, and the air supplement output channel is connected to the combustion hole of the burner, and the air supplement input channel and the air supplement output channel form the gap.

[0016] After adopting the above-mentioned further structure, during the combustion of the burner flame in the burner combustion hole, the heat rises, and the air flow at the air supplement output channel flows quickly, so that secondary air can enter from the opening at the upper end of the air supplement input channel, and then flow to the flame for secondary mixed combustion at the burner combustion hole, thereby improving the combustion efficiency. In addition, during the flow of the secondary air, the cold air cools the first top ring and the second bottom ring seat in the gap, and at the same time the cold air is preheated and returned to participate in the combustion, thereby improving the heat utilization rate and reducing the heat dissipation to the outside through the pot rack.

[0017] Furthermore, an air guide section is provided at the connection between the inner sides of the second bottom ring seat and the second top ring, and the air guide section extends into the combustion hole of the burner.

[0018] After adopting the above-mentioned further structure, the secondary air is guided to the burner flame through the air guide section before entering the burner combustion hole, thereby improving the mixing effect of the secondary air.

[0019] Furthermore, a protruding support column is arranged at the lower end of the first top ring, a groove is arranged at the lower end surface of the second bottom ring seat, and the support column is embedded in the groove.

[0020] After adopting the above-mentioned further structure, the height of the support column is greater than the depth of the groove, so that the inner disk can be better installed in the outer disk, the installation is more convenient, and the contact area between the outer disk and the inner disk can be better reduced, preventing the heat between the outer disk and the inner disk from being transferred and dissipated to each other.

[0021] Furthermore, the first insulation cavity and the second insulation cavity are both vacuum cavities.

[0022] After adopting the above-mentioned further structure, the first insulation cavity and the second insulation cavity can form a double-layer vacuum insulation effect, thereby improving the heat energy gathering effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] It is worth mentioning that the outer plate 1 of the present embodiment covers and wraps the outer side of the inner plate 2 in the circumferential direction, so that the heat can be better gathered in the inner plate 2 to prevent the heat from dissipating outward. The first insulation cavity 6 and the second insulation cavity 7 are both vacuum cavities, which can make the first insulation cavity 6 and the second insulation cavity 7 form a double-layer vacuum insulation effect, thereby improving the heat energy gathering effect.

[0034] Specifically, the outer disk 1 includes a first bottom ring seat 8 and a first top ring 9. First bending sections 10 are provided on both sides of the first top ring 9.
