DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail in the following with the drawings and examples.It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] As Figure 1 And Figure 2 The utility model discloses a heating conversion efficiency increasing device for kitchen cooking gas fuel stove, which is installed on the upper portion of the hearth of the stove, the stove is provided with an ignition device 21 and a flameout protection device 22, the ignition device 21 can be connected with a liquefied gas cylinder to facilitate ignition, and the flameout protection device 22 is convenient for flameout protection.

[0022] This utility model includes a series of vortex-shaped heat-conducting pipes 11. The heat-conducting pipes 11 are rolled into a vortex shape to form a vortex-shaped heat-conducting component 1. The vortex-shaped heat-conducting component 1 is fixed in the upper part of the furnace and closely attached to the heat insulation layer inside the furnace. The vortex-shaped heat-conducting component 1 absorbs the temperature inside the furnace first. Tap water is circulated inside the vortex-shaped heat-conducting component 1 and can be heated. After the tap water inside the vortex-shaped heat-conducting component 1 is heated, it is discharged, which is equivalent to adding an extra layer of protection to the heat insulation layer. It has two functions: first, it provides a protective layer for the heat insulation layer and increases its service life; second, it prevents the temperature of the heat insulation layer from becoming too high and reduces safety hazards.

[0023] In this invention, the inlet end 12 of the vortex-shaped heat-conducting component 1 can be connected to an external water inlet pipe (e.g., connected to a tap water nozzle via a union). Tap water flows within the heat-conducting pipe 11 and is heated through heat conduction in the furnace. The outlet end 13 of the vortex-shaped heat-conducting component 1 can be connected to an external water outlet pipe, which can discharge hot water. This hot water can be used for cooking (adding hot water to the pot to achieve instant boiling), or for subsequent washing of pots and dishes, or for other purposes. By adjusting the water inlet flow, when the water flow... When the water in the heat pipe is heated to a temperature exceeding 100℃, it evaporates into vapor, i.e., water vapor. This vapor is then connected to the steamer via a dedicated pipe, allowing it to work with the steamer to provide secondary pressurization, thereby accelerating the cooking process and shortening the cooking time. When a steamer basket is placed in the working pot to steam items such as buns, steamed bread, or lotus leaf-wrapped meat (a specialty of Hakka cuisine in southern Jiangxi), steam is output through the dedicated pipe connected to the steamer basket, providing secondary pressurization, accelerating the cooking process, shortening the cooking time, improving work efficiency, and saving fuel.

[0024] Currently, only about 20%-50% of the combustion heat energy in existing stoves is used to heat the pot. The remaining half of the heat energy is wasted in two ways: first, it is radiated into the protective insulation layer of the equipment; second, it is directly discharged through the heat dissipation vents. In this invention, the heat in the furnace is absorbed by the vortex-shaped heat-conducting component 1, maximizing the absorption and utilization of the aforementioned wasted heat energy and converting it into efficiency. Moreover, the vortex-shaped heat-conducting component 1 is closely attached to the insulation layer inside the furnace, providing a layer of protection, thereby reducing its heat load, reducing safety hazards, and extending the service life of the equipment. At the same time, it increases the residence time of fuel in the combustion chamber, avoiding excessive and rapid discharge, making combustion more complete, improving the heat conversion rate, increasing work output, reducing emissions, and ultimately achieving the goals of cost reduction, efficiency improvement, and environmental protection.

[0025] In this utility model, the vortex-shaped heat-conducting component 1 is fixed to the heat insulation layer of the furnace by welding or bolting. Moreover, the vortex-shaped heat-conducting component 1 can also be connected to the furnace by a fixing strip. For greater stability, the vortex-shaped heat-conducting component 1 can be placed on the heat insulation layer of the furnace first, and then the two ends of the fixing strip can be welded to the heat insulation layer of the furnace. Finally, the vortex-shaped heat-conducting component 1 and the fixing strip can be welded together to achieve a stable effect.

[0026] In this invention, the spacing between adjacent heat-conducting pipes 11 within the vortex-shaped heat-conducting component 1 is set to an optimal spacing ranging from 0mm to 50mm, depending on the structure and characteristics of different types and models of stoves. Specifically, the spacing between adjacent heat-conducting pipes 11 within the vortex-shaped heat-conducting component 1 is 0mm to 50mm. Preferably, the spacing between adjacent heat-conducting pipes 11 is 3mm, 5mm, or 8mm. The diameter of the metal heat-conducting pipe 11 is 10mm to 40mm. Preferably, the diameter of the heat-conducting pipe 11 is 16mm, 19mm, 25mm, 32mm, 38mm, or 40mm.

[0027] In this invention, the uppermost heat-conducting pipe in the vortex-shaped heat-conducting component 1 is positioned at a suitable location in the stove's heat dissipation vent. Specifically, the uppermost heat-conducting pipe 11 in the vortex-shaped heat-conducting component 1 is positioned at 1 / 3 to 1 / 2 of the stove's heat dissipation vent 23. The diameter of the heat dissipation vent 23 can be reasonably adjusted by the heat-conducting pipe 11, thereby accelerating the heating time of the tap water in the heat-conducting pipe 11. Preferably, the uppermost heat-conducting pipe 11 in the vortex-shaped heat-conducting component 1 covers one-third or one-half of the stove's heat dissipation vent 23.

[0028] In this invention, the heat-conducting pipe 11 of the lowest ring inside the vortex-shaped heat-conducting component 1 passes through the furnace and is connected to the inlet end 12.

[0029] In this utility model, the inlet end 12 of the vortex-shaped heat-conducting component 1 is set on the base 24 of the stove. The inlet end 12 is equipped with a water volume control switch 14 and a water inlet interface 15. The water inlet interface 15 can be connected to an external water inlet pipe, which is connected to a tap water pipe.

[0030] In this invention, the uppermost heat-conducting pipe 11 of the vortex-shaped heat-conducting component 1 extends from the flue of the stove and connects to the outlet end 13. The outlet end 13 is provided with a water outlet 16 and a thermometer 17, which allows for direct and real-time monitoring of the water heating status within the heat-conducting pipe 11. By adjusting the water inlet flow, when the temperature displayed by the thermometer 17 is below 100℃, hot water can be discharged from the outlet pipe. This hot water can be used for subsequent washing of pots and pans, washing of dishes, or as a substitute for other uses. Other uses include: when the temperature gauge 17 shows a temperature higher than 100℃, water vapor is discharged; the water outlet pipe can be connected to the steamer via a dedicated pipe, allowing it to work with the steamer to accelerate the cooking speed and shorten the cooking time; when a steamer is placed in the pot, steam is introduced through a dedicated pipe to accelerate the cooking speed and shorten the cooking time; the heating time of the tap water in the heat pipe 11 can be accelerated by adjusting the diameter of the flue 23 of the stove via the heat pipe 11, and the heating time can be controlled by adjusting the water inlet.

[0031] This utility model also provides a stove equipped with a flameout protection ignition device and a heating conversion efficiency enhancement device for gas and oil cooking stoves disclosed in this utility model. The heating conversion efficiency enhancement device for gas and oil cooking stoves is exposed and mounted in the upper middle part of the stove's combustion chamber.

[0032] In this utility model, the stove is equipped with an ignition device 21 and a flameout protection device 22. The ignition device 21 can be connected to a liquefied gas cylinder for ignition, and the flameout protection device 22 is used to shut off the gas source in case of accidental flameout, thereby providing safety protection.

[0033] Specifically, the heat-conducting pipe 11 of this utility model is made of metal tubular material and is manufactured in a vortex shape. It is directly exposed and fixed to the heat insulation layer inside the furnace. A fluid medium, water (tap water), is introduced into it. Utilizing its own water pressure, the water flows from bottom to top in a vortex shape. At the same time, the metal pipe wall absorbs most of the heat originally radiated to the heat insulation layer of the furnace, rapidly heating the room temperature water flowing in a vortex state inside the heat-conducting pipe 11 to produce hot water / boiling water / steam for use in kitchen cooking operations. At the same time, it also reduces the temperature of the heat insulation layer, effectively extending its service life.

[0034] In this invention, the diameter of the flue (heat dissipation vent) has been reasonably adjusted to slow down the emission speed, thereby increasing the combustion residence time of fuel in the combustion chamber, making the combustion more complete and greatly improving the thermal efficiency. At the same time, it avoids excessive heat loss, allowing the pot to heat up faster and increasing the speed of food preparation. For example, if the stove of this invention is used in rural banquets, it can greatly increase the speed of food preparation. Moreover, the hot water in the heat pipe 11 can be used to wash pots, dishes, etc., without the need to boil water separately, which saves both time and fuel.

[0035] This utility model has undergone dozens of comparative tests and feedback from real users. It takes about 20 seconds to heat tap water in the heat pipe from room temperature to 55°C. To test the efficiency enhancement effect of the working pot, a simple and intuitive test method was adopted: 15 catties of room temperature water at 23°C was added to the pot and brought to a boil, which took 5 minutes. Under this condition, the gas consumption of liquefied petroleum gas is ≤3.2 kg / hour. Compared with several similar traditional stoves widely used on the market today, the time is shortened by about 7 minutes and the gas consumption of liquefied petroleum gas is reduced by about 1.5 kg / hour.

[0036] After testing and verification, the stove of this utility model, without affecting the original cooking function or adding extra fuel, heats up the pot faster, improves the efficiency of serving food, and makes up for the deficiency of single function, achieving multiple uses in one stove. It can also produce free hot water / boiling water / steam, achieving the effect of cost reduction and efficiency improvement. In addition, the complete combustion and reduced heat loss save fuel while reducing the emission of harmful gases and carbon dioxide, thus achieving the effect of energy conservation and environmental protection.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the application of the present utility model technology in kitchen cooking and other oil and gas stoves. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
