[0035] See also Figure 1 , Figure 2 and Figure 3 The embodiment of the utility model provides a commercial energy-saving stove with hot air reabsorption, comprising a stove body 1, a burner 2 and a hot air recovery mechanism 3 are arranged on the stove body 1, a high-pressure area 21 is formed on the top of the burner 2, and a low-pressure area 22 is formed on the bottom;

[0036] The heat recovery mechanism 3 includes a plurality of heat absorbing heads 31 arranged along the outer edge of the high-pressure zone 21 and a heat exhaust ring 32 arranged at the low-pressure zone 22. The plurality of heat absorbing heads 31 are connected to the heat exhaust ring 32 through connecting pipes 33, respectively, so that the heat of the high-pressure zone 21 passes through the heat absorbing heads 31, the connecting pipes 33, the heat exhaust ring 32 and the low-pressure zone 22 in sequence.

[0037] With the above structure, when the commercial energy-saving stove is used, since the stove body 1 is provided with the burner 2 and the heat recovery mechanism 3, a high-pressure area 21 is formed on the top of the burner 2, and a low-pressure area 22 is formed on the bottom; the heat recovery mechanism 3 includes a plurality of heat absorbing heads 31 arranged along the outer edge of the high-pressure area 21 and a heat exhaust ring 32 arranged at the low-pressure area 22, and the plurality of heat absorbing heads 31 are respectively connected to the heat exhaust ring 32 through the connecting pipe 33, so that the heat of the high-pressure area 21 passes through the heat absorbing heads 31, the connecting pipe 33, the heat exhaust ring 32 and the low-pressure area in sequence. 22. Therefore, after the burner 2 ignites the high-pressure flame, the airflow will flow from the low-pressure area 22 at the bottom of the burner 2 to the high-pressure area 21, and the gas in the heat exhaust ring 32 will be brought out by the flow of the airflow, so that a negative pressure is formed in the heat exhaust ring 32. Then, under the action of the negative pressure, the heat in the high-pressure area 21 is sucked into the connecting pipe 33 from the heat absorbing head 31 and then discharged through the heat exhaust ring 32, so that the heat flows from the low-pressure area 22 to the high-pressure area 21 along the flow direction of the airflow, so as to realize heat recovery and utilization, reduce heat dissipation, and avoid energy waste.

[0038] In one embodiment, see Figure 2 and Figure 4 The heat absorbing head 31 is provided with a concave heat absorbing groove 311 on one side facing the high pressure area 21, and the heat absorbing groove 311 is gradually reduced along the cross section close to the high pressure area 21. In actual use, the structure of the heat absorbing groove 311 can increase the air flow velocity sucked into the heat absorbing groove 311, thereby reducing the heat dissipated from the edge of the heat absorbing head 31.

[0039] A connector 312 communicating with the heat absorbing groove 311 is provided on one side of the heat absorbing head 31 away from the high pressure area 21, and the heat absorbing groove 311 is connected to the connecting pipe 33 through the connector 312.

[0040] In one embodiment, see Figure 3 and Figure 5 The heat removal ring 32 is provided with a concave heat collection groove 321 on the side facing the low pressure area 22. The outer edge of the heat removal ring 32 is penetrated by a through hole 322 which is communicated with the heat collection groove 321. The connecting pipe 33 is installed in the through hole 322. In actual use, the heat collection groove 321 is used to concentrate the heat absorbed by the heat absorbing head 31 and allow the heat to flow from the low pressure area 22 to the high pressure area 21. The through hole 322 is used to connect the connecting pipe 33 to the heat removal ring 32 so that the connecting pipe 33 is communicated with the heat collection groove 321.

[0041] The heat exhaust ring 32 is provided with a filter 34 along the heat collecting groove 321. The filter 34 includes a filter plate 341 provided at the notch of the heat collecting groove 321.

At the same time, the inclined setting of the filter plate 341 can make the waste residue on the filter plate 341 fall downward along the inclined surface, thereby preventing the waste residue from remaining on the filter plate 341.

[0042] An outer support ring 343 is provided on the outer edge of the filter plate 341 toward the heat collecting tank 321, and an inner support ring 344 is provided on the inner edge of the filter plate 341 toward the heat collecting tank 321. A plurality of filter holes 342 are provided on the outer support ring 343. In actual use, the outer support ring 343 and the inner support ring 344 are used to support the filter plate 341 on the heat collecting tank 321, and under the setting of the filter holes 342 of the outer support ring 343, the gas of the connecting pipe 33 can enter the heat collecting tank 321 through the filter holes 342 of the outer support ring 343.
