Definitions

  • the invention relates to a kettle, in particular to a fast and energy-saving kettle. Background technique
  • the commercially available open kettle is a kettle body with a flat bottom structure.
  • the water in the kettle is mainly heated by the heated kettle bottom. Due to the limited contact area between the water and the surface of the kettle bottom, its thermal efficiency is low.
  • FIG. 1 Chinese Patent Application No. 89213076. 8 discloses an open kettle with an air duct in the kettle body, which increases the heating efficiency by increasing the heating area of the kettle body.
  • the air duct is designed to pass directly to the bottom of the kettle, the heat generated by the flame will quickly dissipate outward from the air outlet of the air duct; moreover, because the bottom of the kettle is still a flat-bottom structure, it is still used during use. A considerable part of the flame or heat escapes from the bottom of the pot to the outside of the pot, which affects the full use of energy.
  • the purpose of the present invention is to overcome the shortcomings of the prior art and provide a fast and energy-saving open kettle that can gather heat and make full use of energy.
  • the fast and energy-saving open kettle comprises a kettle body, a spout and a kettle lid, at least two air ducts arranged on the inner side wall of the top of the kettle body, extending toward the bottom of the kettle body, and connected to the air pipe and A heat exchanger in the center of the bottom of the kettle body; a top of the heat exchanger is provided with a through hole connected to the air duct, and an opening is provided at the bottom of the heat exchanger to the outside of the kettle bottom.
  • a fire-collecting cavity recessed inward may be further provided at the bottom of the kettle body.
  • the fast and energy-saving kettle of the invention due to the function of the heat exchanger, enables the heat formed by combustion to be gathered and circulated in the center of the kettle body, and thereby diffuses around the kettle body, making full use of the heat source; Set to help guide and focus the flame. Center on the bottom of the pot And the inside of the heat exchanger, it can effectively prevent the flame or heat from escaping from the bottom of the kettle body.
  • the penetration of heat exchangers and air ducts is conducive to the dissipation of heat and exhaust.
  • the heated area of water is also increased, and the heat conversion efficiency of the improved kettle can be improved by more than 40%.
  • FIG. 1 is a schematic structural diagram of a conventional kettle
  • FIG. 2 is a schematic structural diagram of a quick and energy-saving kettle according to the present invention.
  • FIG. 3 is a top view of the kettle shown in FIG. 2. Best Mode of the Invention
  • the fast energy-saving open kettle of the present invention includes a kettle body 1, a heat exchanger 2, a spout 3, an air pipe 5, and a kettle lid (not shown).
  • the air outlet port of the air guide tube 5 is provided on the side wall of the top of the pot body 1 by pressure welding, for example, it can be provided with two or more at approximately equal distances along the circumferential direction of the pot body 1.
  • the air inlet end of the air duct 5 extends toward the bottom of the kettle body 1, and the heat exchanger 2 is disposed between the air inlet end and the center of the bottom of the kettle body 1.
  • the heat exchanger 2 has, for example, a disc shape, and a through hole connected to the air inlet port of the air duct 5 is opened at the top, and the two are integrated by, for example, pressure welding.
  • the bottom of the heat exchanger 2 is provided with a pot body. 1 ⁇ bottom opening 20.
  • the bottom of the pot body 1 is recessed inwardly to form a fire-collecting cavity 7, and the central part of the fire-collecting cavity 7 is provided with an opening connecting with the above-mentioned opening 20, and the two are also integrated into one body by, for example, pressure welding.
  • the flame is guided by the fire collection chamber 7 to concentrate heat on the bottom of the kettle body 1 and the inside of the heat exchanger 2. Due to the reflection of the heat source on the top and side walls of the heat exchanger 2, the heat generated by the combustion It can circulate and accumulate inside the heat exchanger 2, and the heat generated by the combustion is fully utilized and finally forms exhaust gas to be discharged out of the kettle through the air duct 5.
  • the heat exchanger 2 may also adopt a hemispherical shape or other shapes, but they all fall within the scope of the present invention.
  • the fast energy-saving open kettle of the present invention can be used to heat or cook drinking water, beverages, or other fluid foods.
