[0045] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown in

[0046] Specifically, during use, the burner 300 ignites the gas, and the flame flows along the heat exchange tube 100 and is finally discharged. When the flame flows through the heat exchange tube 100, it will be blocked by the flame retardant plate 220, so that the flame passes through the fire-passing holes 221 on the flame retardant plate 220 and the gap between the flame retardant plate 220 and the heat exchange tube 100, thereby enabling the flame to better heat the heat exchange tube 100 and significantly improving the thermal efficiency.

[0047] It should be noted that during actual use, the thermal efficiency can reach 65% - 70%, effectively reducing the gas cost of users, and can improve the heating rate, enabling the gas fryer to reach the set temperature faster.

[0048] Among them, a chimney member 400 is connected to the fire outlet of the heat exchange tube 100.

[0049] See Figure 1 - Figure 11As shown, in an alternative solution of this embodiment, the flame retardant plate 220 is V-shaped, and the connecting plate 210 and the flame retardant plate 220 are connected in a fishbone shape.

[0050] Specifically, the flame retardant plate 220 can be set to a V shape, and the connecting plate 210 and the flame retardant plate 220 are connected in a fishbone shape, so that the flame passes through multiple flame retardant plates 220 in sequence, increasing the time for heat to stay in the heat exchange tube 100. Moreover, through holes 221 are provided on the flame retardant plate 220, and the setting of the through holes 221 does not block the flow of the flame.

[0051] It should also be noted that those skilled in the art can set the shape of the flame retardant plate 220 according to actual needs, which will not be elaborated here.

[0052] See Figure 1 - Figure 11 As shown, in an alternative solution of this embodiment, the flame retardant plate 220 is arranged at an acute angle to the extending direction of the heat exchange tube 100, and the tip of the flame retardant plate 220 faces the fire inlet 110 of the heat exchange tube 100.

[0053] Specifically, by making the tip of the flame retardant plate 220 face the fire inlet 110 of the heat exchange tube 100, the flame retardant plate 220 can separate the flame, causing the flame to flow along the flame retardant plates 220 on both sides of the connecting plate 210.

[0054] See Figure 1 - Figure 11 As shown, in an alternative solution of this embodiment, the multiple flame retardant plates 220 are respectively a first flame retardant plate 222, a second flame retardant plate 223, a third flame retardant plate 224, and a fourth flame retardant plate 225, and the diameters of the through holes 221 on the first flame retardant plate 222, the second flame retardant plate 223, the third flame retardant plate 224, and the fourth flame retardant plate 225 gradually decrease.

[0055] Among them, the positions of the through holes 221 on the first flame retardant plate 222, the second flame retardant plate 223, the third flame retardant plate 224, and the fourth flame retardant plate 225 correspond to each other.

[0056] Specifically, the number of fire retardant plates 220 can be set to four, and the diameters of the fire-passing holes 221 on the first fire retardant plate 222, the second fire retardant plate 223, the third fire retardant plate 224, and the fourth fire retardant plate 225 gradually decrease. At the same time, the positions of the fire-passing holes 221 on the first fire retardant plate 222, the second fire retardant plate 223, the third fire retardant plate 224, and the fourth fire retardant plate 225 correspond to each other. Through such a setting, when the flame passes through the fire retardant plate 220, a part of the combusted gas will be discharged through the gradually decreasing holes on the fire retardant plate 220. Another part of the combusted gas will form local swirling eddies when it encounters the inclined plane folded at a certain angle, prolonging the residence time of heat in the heat exchange fire tube. Most of the heat of the combusted gas is absorbed by the oil cylinder 600, and a small amount of tail gas is discharged from the chimney part 400.

[0057] In addition, auxiliary holes 226 with the same diameter are provided at the bending positions of each fire retardant plate 220.

[0058] It should also be pointed out that those skilled in the art can set the number of fire retardant plates 220 according to actual needs, which will not be elaborated here.

[0059] See Figure 1 - Figure 11 As shown, in an alternative solution of this embodiment, a hook 230 is provided on the connecting plate 210, and the hook 230 can be hooked at the fire inlet 110 of the heat exchange tube 100.

[0060] Specifically, a hook 230 is provided on the connecting plate 210, and the hook 230 can be hooked at the fire inlet 110 of the heat exchange tube 100. Through such a setting, it is convenient for the staff to replace the fire retardant member 200.

[0061] See Figure 1 - Figure 11 As shown, this embodiment provides an energy-saving gas fryer, including a fryer cabinet 500, an oil cylinder 600, and a gas fryer fire retardant structure; the oil cylinder 600 is arranged on the fryer cabinet 500, and the heat exchange tube 100 is inserted into the oil cylinder 600.

[0062] Among them, the heat exchange tube 100 is welded in the oil cylinder 600, so that the edible oil in the oil cylinder 600 can directly contact the heat exchange tube 100, improving the heat exchange efficiency.

[0063] Specifically, the energy-saving gas fryer has the advantages of the above-mentioned gas fryer fire retardant structure compared with the prior art, which will not be elaborated here.

[0064] Among them, a heat insulation layer 610 is arranged around the oil cylinder 600. Through the setting of the heat insulation layer 610, the heat loss of the oil cylinder 600 is reduced.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
