Background technique

At present, gas ranges have become commonly used household or commercial cooking utensils. The pots of the existing gas stoves mainly have two aspects for the utilization of heat energy: one, the flame (ie energy) generated by the combustion of the gas stove directly acts on the bottom of the pot, and absorbs heat radiation at the same time; Burning gas causes it to glow red and radiate to the bottom of the pot. However, these two methods have the disadvantages of low heat energy utilization rate and large heat loss.

detailed description

The economizer structure of the gas cooker of the preferred embodiment of the present invention is shown in Figure 1 and Figure 2, can refer to Figure 3 simultaneously, comprises the heat insulation ring 10 that the bottom is provided with opening (this heat insulation ring is responsible for collecting the energy generated from the gas cooker The thermal energy carried by the hot air flow that is not absorbed by the bottom of the pot), the shape of the heat insulation ring 10 is suitable for the shape of the pot (for example: bowl shape); the inner surface of the heat insulation ring 10 is provided with a serrated fire gathering layer 20; And the fire-gathering layer 20 is the hot air passage 40 for the purpose of increasing the contact area between the hot air and the pot; the hot air passage 40 forms a certain angle with the outer surface of the pot, and forms a certain angle with the horizontal plane; The bottom 31 is closed and the top is open, and both the bottom and the top of the hot air flow channel 40 are open. This prevents the flame from passing through the fire separation zone 30 , and all the flames rise slowly through the hot air flow channel 40 . The pot can fully absorb heat energy, while saving energy, it can also improve cooking efficiency; at the same time, the fire insulation zone 30 is set to block the direct heat exchange between the heat insulation ring 10 and the hot air flow, so as to avoid the external temperature of the heat insulation ring from being too high. It is safer to use because it is too high to cause unnecessary burns to cooks; more importantly, it prevents heat energy from radiating out through the heat insulation ring.

Further, as shown in Fig. 1 and Fig. 2, the fire accumulating layer 20 in the above-mentioned embodiment is composed of a plurality of saw-toothed ribs connected, and the plurality of saw-toothed ribs are rotated from the bottom of the heat insulation ring 10 in the same direction to rise to The top of the thermal insulation ring 10. In this way, a plurality of rotating and rising hot air flow passages 40 are formed between the plurality of serrated ribs and the outer surface of the pot, and the rotation of the hot air flow passages rises to reduce the flame rising speed and increase the heat transfer between the hot air flow and the pot. The exchange time and increase the area of heat exchange, improve the efficiency of heat exchange, thereby improving the utilization rate of heat energy, so that the pot can fully absorb heat energy.

Preferably, as shown in FIGS. 2 and 3 , each of the serrated ribs in the above embodiment includes a connected first folded edge 21 and a second folded edge 22 , and the first folded edge 21 and the second folded edge 22 intersect. into an acute angle. The connection between the first folded edge 21 and the second folded edge 22 and the connection with the inner surface of the heat insulation ring 10 form a plurality of zigzag ribs, and the area between the ribs facing the pot constitutes the fire accumulating layer 20 . The interval between the ribs facing the heat insulation ring constitutes a fire isolation zone 30, through which the high temperature of the flame can be prevented from being directly transmitted to the outer surface of the heat insulation ring 10, so as to prevent the external temperature of the heat insulation ring 10 from being too high and causing damage to cooking. or cause unnecessary burns, making the economizer safer to use.

Specifically, in the above-mentioned embodiment, as shown in Fig. 1 and Fig. 3, one side of the first hem 21 and the second hem 22 of the saw-toothed rib are connected, and the other side that is not connected is welded on the other side. on the inner surface of the thermal ring 10. The interval formed between the first folded edge 21 and the second folded edge 22 of two adjacent zigzag convex ribs and the outer surface of the pot is a fire accumulating layer, that is, a hot air flow channel 40; a plurality of first folded edges 21, The section formed by the second folded edge 22 and the inner surface of the heat insulation ring 10 is a fire insulation area 30 .
