Description

Technical Field

[0001] The present invention relates to the technical field of cooking stoves, and particularly to a circulating air energy-saving stove. Background Art

[0002] The heat exchange methods between existing gas stoves and cookware mainly include three types: thermal radiation, thermal convection, and heat conduction, among which thermal convection accounts for the highest proportion. The air-fuel (air and gas) mixture flowing out of the inner fire holes and / or outer fire holes is ignited to form a combusting gas; the temperature of this part of the combusting air-fuel mixture is relatively high, and the heat exchange with the bottom of the pot (the bottom of the cookware) is thermal convection, and there is also a small part of thermal radiation; the high-temperature flue gas generated after the combustion of the above gas continues to conduct thermal convection heat exchange with the bottom of the pot, and the temperature gradually decreases during the heat exchange process until it leaves the bottom of the pot. The above is the main form of heat exchange between gas combustion of a gas stove and the bottom of the pot.

[0003] When existing air stoves are in use, the initial temperature of the combustion medium needs to be heated to a certain extent after ignition to reach the ideal temperature. In this way, the power of the gas is released through the pressure inside the gas valve as the power, so the flame combustion intensity is limited. Summary of the Invention

[0004] The purpose of the present invention is to provide a circulating air energy-saving stove to solve the above problems.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A circulating air energy-saving stove, including an outer jacket, an inner jacket, and a horn-shaped flame concentrating platform. The outer jacket, the inner jacket, and the horn-shaped flame concentrating platform are integrally formed. An air heating cavity is formed between the outer jacket and the inner jacket. The horn-shaped flame concentrating platform is annularly provided with a plurality of discharge holes. The inner wall of the inner jacket is fixedly connected with a spiral water pipe through a plurality of support members.

[0006] At the center of the bottom of the inner wall of the horn-shaped flame concentrating platform, a flame outlet nozzle is provided. A spark plug is located in the central cavity below the horn-shaped flame concentrating platform. The outlet of the mixed gas pipe is located at the ignition point of the spark plug, and the mixed gas pipe mixes the mixed gas in the mixing cavity.

[0007] Preferably, a water inlet pipe and a water outlet pipe are further provided at the bottom of the outer jacket. The water inlet pipe and the water outlet pipe are respectively fixed to the two interfaces of the spiral water pipe.

[0008] Preferably, an air inlet hole and an air outlet hole are further provided at the bottom of the outer jacket.

[0009] Preferably, an exhaust gas discharge port is provided at the bottom of the outer jacket.

[0010] Preferably, the discharge hole includes a through-channel, with inward-facing air inlets on both sides of the through-channel and an air outlet facing the spiral water pipe. A circular space is provided between the air inlet and the air outlet, and a metal ball is placed in the circular space. Two flame-diverting baffles are provided in the circular space, respectively facing the air outlet and the air inlet. A diffusion chamber is formed between the flame-diverting baffles. An elastic support and a side baffle are provided near the air outlet of the circular space.

[0011] Technical effects and advantages of the present invention:

[0012] The normal-temperature air in the air heating chamber is heated by absorbing the heat of the fire flare discharge hole; after heating, it is mixed with fuel, so that the same fire flare temperature can be achieved with less fuel consumption, thus achieving the purpose of energy conservation.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0017] Refer to Figures 1 to 3 As shown, the present invention provides an embodiment, a circulating air energy-saving stove, including an outer sleeve 2, an inner sleeve 3 and a horn-shaped flame concentrating table 1. A protective seat 12 is placed on the horn-shaped flame concentrating table 1. The outer sleeve 2, the inner sleeve 3 and the horn-shaped flame concentrating table 1 are integrally formed. An air heating chamber 4 is formed between the outer sleeve 2 and the inner sleeve 3. The horn-shaped flame concentrating table 1 is provided with a plurality of discharge holes 13 in a circular shape. The inner wall of the inner sleeve 3 is fixedly connected with a spiral water pipe 5 through a plurality of support members 6;

[0018] The bottom center of the inner wall of the horn-shaped flame concentrating table 1 is provided with a flame outlet nozzle 8. The spark plug 17 is located in the central cavity below the horn-shaped flame concentrating table 1. The outlet of the mixed gas pipe 10 is located at the ignition point of the spark plug 17, and the mixed gas pipe 10 mixes the mixed gas in the mixing chamber 9.

[0019] The spark plug 17 ignites, and the flame heats the water in the spiral water pipe 5 through a circle of flame discharge holes 13. The heated spiral water pipe 5 and the remaining heat will be transferred to the air heating chamber. Air is continuously injected into the air heating chamber through the air inlet holes. After being heated in the air heating chamber 4 and then connected to the mixing chamber 9 through the conduit, the combustion medium in the mixing gas pipe 10 enters the mixing chamber 9 and mixes with the fuel. The air flow rate increases, causing the gas to be quickly carried out and accumulate in the mixing chamber 9. The internal pressure further increases. At this time, the power of the flame can be enhanced, and this cycle continues, which can increase the initial temperature of the fuel and achieve the purpose of energy conservation.

[0020] It should be noted that the spiral water pipe 5 makes the temperatures of the horn flame concentrating platform 1 and the local part of the outer sleeve 2 relatively lower than the existing temperatures, effectively protecting the overall lifespan and preventing deformation.

[0021] It should be understood that a water inlet pipe 11 and a water outlet pipe 18 are also provided at the bottom of the outer sleeve 2. The water inlet pipe 11 and the water outlet pipe 18 are respectively fixed to the two interfaces of the spiral water pipe 5 to ensure the stable circulation of the water flow in the spiral water pipe 5.

[0022] Specifically, an air inlet hole 14 and an air outlet hole 15 are also provided at the bottom of the outer sleeve 2.

[0023] Specifically, an exhaust gas discharge port 16 is provided at the bottom of the outer sleeve 2.

[0024] It should be noted that:

[0025] The discharge hole 13 includes a through-channel 131. There are inward air inlets and air outlets facing the spiral water pipe 5 on both sides of the through-channel 131. A circular space is provided between the air inlet and the air outlet. A metal ball A is placed in the circular space. Two flame dividing baffles 132 respectively facing the air outlet and the air inlet are provided in the circular space. A diffusion chamber 133 is formed between the flame dividing baffles 132. An elastic support 134 and a side baffle 135 are provided near the air outlet in the circular space.

[0026] When the flame is discharged through the discharge hole 13, due to the influence of the wok above, when the flame is concentrated at the position of the discharge hole 13, the air flow pressure causes the flame entering the through-channel 131 to pass through the flame dividing baffle 132. First, the air inlet will be blocked by the flame dividing baffle 132, enabling each of the internal air inlets to receive the air flow and also increasing the upward power of the flame. In addition, after the air flow entering the diffusion chamber 133 accumulates, under the block of the flame dividing baffle 132 at the air outlet, heat is formed and sprayed to the position of the spiral water pipe 5, which can completely concentrate the heat at the position of the spiral water pipe 5, thereby increasing the heat concentration utilization rate and also increasing the initial temperature during combustion;

[0027] When the air flow of the flame is relatively large, the flame pushes the metal ball A, and the metal ball A crosses over the elastic support 134, thereby increasing the diameter of the air inlet. While releasing the heat pressure, it ensures that the flame is quickly sprayed to the position of the spiral water pipe 5. The side baffle 135 can make the metal ball A return to its original state.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
