[0027] Example

[0028] This embodiment provides an energy-saving commercial gas-fired large-pot stove, such as... Figures 1-4 As shown, it includes: a stove body 101, with adjustable support legs 103 symmetrically arranged at the bottom of the stove body 101, an installation groove 107 opened at the top of the stove body 101, a gas stove 108 fixedly installed in the center of the installation groove 107, and an adjustment valve 104 fixedly connected to the front side of the stove body 101; a heat recovery mechanism 200, which is set inside the stove body 101, for absorbing and utilizing the waste heat generated by the gas stove 108; and an expansion mechanism 300, which is set on one side of the stove body 101, for expanding the usable area of ​​the top of the stove body 101.

[0029] An energy-saving commercial gas stove employing the above technical solution is equipped with a heat recovery mechanism 200. The heat is absorbed by the heat-conducting plate 202, and the heat is conducted through the heat-conducting plate 202 to the cold water in the heating tank 203 to heat the cold water. After heating, the cold water enters the water storage chamber 204 and is kept warm by the insulated water tank 201, thus realizing the reuse of waste heat. The heat-conducting plate 202 increases the heating area, improves the heating effect of the water in the water storage chamber 204, and improves the utilization effect of waste heat.

[0030] For water storage, the heat recovery mechanism 200 includes an insulated water tank 201 fixedly connected to the mounting groove 107. The insulated water tank 201 is arranged in a ring shape and has a water storage chamber 204 inside. A drain pipe 205 and a water inlet pipe 206 connected to the water storage chamber 204 are respectively provided on one side of the stove body 101. Cold water is added to the water storage chamber 204 through the water inlet pipe 206. After the cold water is heated, it is discharged through the drain pipe 205, realizing the utilization of waste heat.

[0031] To fully utilize waste heat, a heat-conducting plate 202 is used to increase the surface area for receiving waste heat, absorbing excess heat and using it to heat the water in the heating tank 203, thus realizing the utilization of waste heat. Multiple heat-conducting plates 202 are evenly distributed on the inner ring surface of the insulated water tank 201, and heating tanks 203 are formed inside the heat-conducting plates 202, which are fixedly connected to the water storage cavity 204.

[0032] For placing cookware, the insulated water tank 201 is concentrically positioned with the gas stove 108, and the heat-conducting plate 202 does not contact the outer wall of the gas stove 108. The cookware is placed on top of the insulated water tank 201 and heated by the gas stove 108.

[0033] To monitor the water level in the water storage chamber 204, a connecting pipe 207 is fixedly connected to the front of the stove body 101, with both ends of the connecting pipe 207 fixedly connected to the water storage chamber 204. The connecting pipe 207 forms a communication device with the inside of the water storage chamber 204, allowing for real-time monitoring of the water volume within the chamber.

[0034] For storing kitchen seasonings and other condiments, the expansion mechanism 300 includes an expansion plate 301 rotatably connected to the right side of the stove body 101, with a support frame 302 snapped between the expansion plate 301 and the stove body 101. The support frame 302 supports the expansion plate 301, and the expansion plate 301 is used to store fillings and other condiments.

[0035] To prevent the top of the stove body 101 from overheating, a back plate 102 is fixedly connected to the top of the stove body 101. A water basin 106 is fixedly installed on the right side of the top of the stove body 101, and a water outlet pipe 105 corresponding to the water basin 106 is fixedly installed on the front side of the back plate 102. Opening the water outlet pipe 105 allows cold water to flow into the water basin 106 for the cook to use. At the same time, excess water flows out from the water basin 106 to cool the top of the stove body 101.

[0036] In summary, the energy-saving commercial gas-fired large-pot stove provided in this embodiment has the following advantages: a heat recovery mechanism 200 is provided, which absorbs the waste heat generated by the gas furnace 108 through the heat-conducting plate 202. The heat is conducted through the heat-conducting plate 202 to the cold water in the heating tank 203 to heat the cold water in the heating tank 203. After heating, the cold water enters the water storage chamber 204 and is kept warm by the insulated water tank 201, realizing the reuse of waste heat. The heat-conducting plate 202 increases the heating area, improves the heating effect of the water in the water storage chamber 204, and improves the utilization effect of waste heat.

[0037] By absorbing waste heat from the gas furnace and heating water through the heat-conducting plate 202, gas consumption is significantly reduced. Heat recovery can greatly improve thermal efficiency, meeting the stringent energy consumption control requirements of commercial scenarios. It is expected to significantly reduce operating costs, making it especially suitable for large canteens or hotels that use the gas frequently.

[0038] In use, cold water is added to the insulated water tank 201 through the inlet pipe 206, and the pot is placed on top of the insulated water tank 201. The pot is then heated by the gas stove 108. When the gas stove 108 is heating, the high temperature of the flame heats the heat-conducting plate 202. The heated heat-conducting plate 202 then transfers heat to the water in the heating tank 203, heating the water and utilizing waste heat. The water level in the insulated water tank 201 can be observed through the connecting pipe 207, and the water temperature in the insulated water tank 201 can be sensed by lightly touching the surface of the connecting pipe 207. Hot water is released from the insulated water tank 201 through the drain pipe 205.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
