Description

Technical Field

[0001] The invention relates to the technical field of burners, in particular to a vacuum energy-gathering pot rack. Background Art

[0002] In the gas burner in the prior art, a pot rack is usually installed on the burner to support the pot so that the bottom of the pot is burned by the flame in the pot rack.

[0003] In the existing pot rack structure, usually only an annular hardware support leg is set on the burner. This annular hardware support leg has relatively many hollow parts. When the flame burns, the heat is easily dissipated to the surroundings, resulting in uneven heat around and scattered air flow, resulting in a relatively high heat loss rate.

[0004] However, there is also a kind of concave pot rack on the market. This concave pot rack has a relatively high wrapping on all sides. After the pot is placed on it, there is only a small gap between the bottom of the pot and the edge of the pot rack, which makes the internal temperature insulation performance relatively high. However, the pot itself is also a metal part, and the heat will also be dissipated from the inside to the outside through heat transfer. The heat utilization rate needs to be further improved. Summary of the invention

[0005] In order to overcome the defects of the prior art, the present invention provides a vacuum energy-gathering pot stand to solve the problems in the prior art.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a vacuum energy gathering pot stand, including an energy gathering plate, the upper end of the energy gathering plate is concave and forms a concave cavity, the middle part of the energy gathering plate is provided with an air replenishment channel, the energy gathering plate includes a top ring and a base, the top ring cover is arranged on the base so that the vacuum layer is formed between the top ring and the base.

[0007] The beneficial effect of the present invention is that by concentrating the heat in the concave cavity, under the action of the vacuum layer, the thermal insulation performance of the concave cavity can be improved, and the heat transferred from the inside to the outside through the energy-gathering ring disk can be further reduced, thereby improving the thermal utilization rate. The air replenishment channel allows air to enter the concave cavity from below to provide secondary air replenishment for the flame. The air flows evenly, preventing the heat from being unevenly dissipated to the surroundings, thereby improving the combustion efficiency.

[0008] Furthermore, the base has a cavity, the vacuum layer is a vacuum liner, the vacuum liner is embedded and installed in the cavity, the lower end of the middle part of the top ring abuts against the upper end surface of the vacuum liner, the lower end of the vacuum liner abuts against the inner lower end of the base, and a vacuum liner cavity is provided in the vacuum liner.

[0009] After adopting the above-mentioned further structure, by installing a vacuum liner in the cavity, the heat is further isolated in the concave cavity, the thermal insulation effect is better, and the middle part of the top ring can also be supported by the vacuum liner, so that the pressure of the pot can be more evenly dispersed on the entire pot rack, and the supporting performance is better.

[0010] Furthermore, a separation ring is arranged in the cavity, and an edge of the separation ring is sealedly connected to the top ring, so that the vacuum layer is formed between the separation ring and the top ring.

[0011] After adopting the above-mentioned further structure, the separation ring is sealed and connected with the top ring, so that the top ring has greater strength and better supporting performance, and the formed vacuum layer can reduce the internal heat transfer area and improve the thermal insulation capacity.

[0012] Furthermore, a support ring is positioned and installed on the concave cavity, the support ring is positioned and installed on the upper end of the top ring, the support ring is provided with supporting feet, and the lower end of the base is provided with supporting feet.

[0013] After adopting the above-mentioned further structure, the cookware is supported by the supporting feet, so that the heat is concentrated in the bottom of the pot and the concave cavity. Under the action of the vacuum layer, the heat utilization rate is improved. The supporting feet can make the base a suspended design, so that air can enter from the bottom of the base through the air replenishment channel to facilitate the replenishment of secondary air and improve the combustion efficiency of the flame.

[0014] Furthermore, a bending groove is provided on the outer edge of the top ring, and a limiting ring is provided on the outer edge of the base, a supporting step is formed between the limiting ring and the base, the bending groove is mounted on the supporting step, an L-shaped metal sheet is installed in the bending groove by screws to form a limiting cavity between the bending groove and the L-shaped metal sheet, and the limiting ring is inserted in the limiting cavity.

[0015] After adopting the above-mentioned further structure, the top ring can be better erected on the base, and under the action of the limiting cavity, the top ring can be further stably installed on the base to prevent the structure from being loose and improve the supporting performance.

[0016] Furthermore, the L-shaped metal sheet and the limiting ring are fixedly connected via connecting pins.

[0017] With the above further structure, the edge of the base and the L metal sheet are closer together, the structure is more compact, and the overall supporting performance is further improved.

[0018] Furthermore, the screw head of the screw is located at the upper end of the bending groove, the bracket ring is mounted on the upper end of the bending groove, and the lower end of the bracket ring is provided with a positioning groove corresponding to the screw head.

[0019] After adopting the above-mentioned further structure, the support ring can be positioned by the screw head to prevent the support ring from accidentally detaching, and the lower part of the support foot can extend into the concave cavity, making the support ring more stable and preventing shaking.
