The closed cavity 100 is filled with air or vacuum, and the heat conducting performance of the air and the vacuum is far lower than that of metal, so that the closed cavity 100 can play a good role in heat insulation; the inner cavity of the heat exchange ring 21 is communicated with the closed cavity 100, so that the volume of the closed cavity 100 is increased, and the heat insulation effect of the pot frame is enhanced. The space between the pot holder body 10 and the burner 20 that is not in contact with each other is a secondary air supply passage 200. When the burner 20 is started, the gas is burned so that the secondary air automatically flows along the lower disk 2 toward the secondary-air supply passage 200. Because the secondary air backflow region exists between the adjacent heat exchange rings 21, the secondary air forms backflow when passing through the secondary air backflow region, flows as shown by arrows in fig. 2, the flow velocity of the secondary air is delayed, the flow path of the secondary air is prolonged, and the retention time of the secondary air is increased, so that the secondary air can be fully preheated and enters the secondary air supply passage 200 to participate in combustion, the temperature of flame is favorably increased, the temperature of a combustion cavity is increased, and the thermal efficiency is improved. Because the upper layer disc 1 and the lower layer disc 2 are in contact with each other to conduct heat, the temperature of the lower layer disc 2 is still 100-200 ℃, secondary air can be preheated by the lower layer disc 2, heat recycling is realized, and the energy utilization rate is improved.

With reference to fig. 1, the upper disc 1 is an annular disc, and the upper surface of the upper disc 1 is a concave arc surface with a low inside and a high outside, that is, a concave arc surface with a low annular inner hole edge and a high annular outer edge; the concave arc surface is provided with a pot rack upper foot sheet 3 for supporting a pot.

The pot rack upper leg pieces 3 are provided with a plurality of pieces, and the plurality of pot rack upper leg pieces 3 are uniformly arranged along the circumferential direction of the upper-layer disc 1. In the embodiment, the pot rack upper foot pieces 3 are provided with four pieces, and certainly, the pot rack upper foot pieces 3 can also be provided with three or five pieces and the like, and the design can be carried out according to actual requirements.

The lower disc 2 is an inward concave annular disc with an annular lower concave cavity; the bottom end of the lower layer disc 2 is provided with a pot rack lower leg piece 4 for supporting a pot rack. Specifically, the upper tray 1 is disposed above the lower tray 2 for covering the annular lower cavity to enclose the sealed cavity 100.

Optionally, as shown in fig. 2, the edge of the upper disc 1 has an annular overlap edge, and the edge of the lower disc 2 has an annular flange, and the overlap edge and the flange are fixed in an attaching manner, so that contact heat conduction is realized, and fixed connection is facilitated.

The pot rack lower leg pieces 4 are provided with a plurality of pieces, and the plurality of pot rack lower leg pieces 4 are uniformly arranged along the circumferential direction of the lower layer disc 2. In this embodiment, the pan frame lower leg pieces 4 are provided with four pieces, and certainly, the pan frame lower leg pieces 4 can also be provided with three or five pieces, and the like, and the design can be carried out according to actual requirements.

In the present embodiment, the cross-sectional shape of the heat exchanging ring 21 includes a circular shape, a rectangular shape, and an irregular shape as long as secondary air can be blocked.

The embodiment also provides a gas stove, which comprises the gas stove wok stand, and the heat efficiency of the gas stove is obviously improved due to the gas stove wok stand.

Second embodiment

This embodiment provides a gas range wok stand, which is substantially the same as the gas range wok stand in the first embodiment, except that: the wok stand body 10 further comprises an outer-layer disc 5.

Specifically, as shown in fig. 3 and 4, the outer disc 5 is sleeved outside the lower disc 2, and the outer disc 5 is a concave annular disc having an annular lower cavity and similar to the lower disc 2 in structure; form secondary air between outer dish 5 and the lower floor's dish 2 and preheat passageway 300, form high temperature flue gas district 400 between outer dish 5, upper disc 1 and the lower floor's dish 2, secondary air can flow to high temperature flue gas district 400 after preheating through secondary air preheating passageway 300.

By adding the outer layer disc 5, the heat transferred from the lower layer disc 2 to the outside can be directly reduced, and the effects of heat insulation and heat preservation are achieved. The space that does not contact between outer layer dish 5 and the lower floor's dish 2 forms secondary air and preheats passageway 300, realizes the reposition of redundant personnel to the secondary air, and the secondary air flows along outer layer dish 5 below, and partly direct entering secondary air supply passageway 200 participates in the burning, and another part gets into secondary air and preheats passageway 300. The heat exchange rings 21 are disposed in the secondary air preheating passage 300, and since a secondary air backflow region exists between adjacent heat exchange rings 21, the secondary air forms a backflow when passing through the secondary air backflow region, and flows as indicated by arrows in fig. 4, thereby delaying the flow rate of the secondary air, extending the flow path of the secondary air, and increasing the residence time of the secondary air, so that the secondary air is sufficiently preheated and then flows to the high temperature flue gas region 400.

Because the existing pot frame does not shield the high-temperature flue gas, the high-temperature flue gas is directly contacted with the outside air, the heat exchange between the flue gas and the pot wall is reduced, and the heat efficiency of the gas stove cannot be further improved.

In order to solve the above problem, the top edge of the outer disc 5 of the present embodiment is provided with a baffle ring 51, and the diameter of the baffle ring 51 is larger than the diameter of the upper disc 1 and the lower disc 2, so that the baffle ring 51 can block and guide the high temperature flue gas, thereby forming a high temperature flue gas region 400. On one hand, the high-temperature flue gas area 400 conducts turbulent flow on the high-temperature flue gas, delays the flowing speed of the high-temperature flue gas, and strengthens heat exchange between the flue gas and the boiler wall. On the other hand, the secondary air can react with the high-temperature flue gas, and the secondary air reacting with the high-temperature flue gas is preheated through the secondary air preheating channel 300, so that the reaction of the high-temperature flue gas and the secondary air is more sufficient, the flue gas temperature is increased, the heat exchange between the high-temperature flue gas and the boiler wall is enhanced, and the further improvement of the heat efficiency is facilitated.

Optionally, the outer-layer disc 5 is provided with a slot 52 corresponding to the pan frame lower leg piece 4, and the pan frame lower leg piece 4 is inserted into and fixed to the slot 52, so as to fix the outer-layer disc 5. Preferably, the fixing manner of the wok stand lower leg piece 4 and the slot 52 can be, but not limited to, interference fit or welding connection.

Note that the above description is only for the preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious modifications, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
