Description

Technical Field

[0001] This invention relates to a device for improving thermal efficiency by placing a multi-layered, easily replaceable aluminum foil basin inside an energy-saving basin for infrared reflection and heat insulation, and is used in household gas stoves. Background Technology

[0002] This year, energy-saving pot racks have become popular on gas stoves to improve thermal efficiency. These racks are typically welded together, but this design only improves thermal efficiency when using large flat-bottomed pans (30cm or more). However, it has little effect on the thermal efficiency of round-bottomed woks, which are the primary cooking pans used in Chinese households. The reasons are as follows: Please see Figure 1 , Figure 1 The diagram shows the structure and operation of an existing gas stove equipped with an energy-saving pot holder, on which a large flat-bottomed pan and a wok are placed. In the diagram, 1 is the gas stove part, 1-1 is the gas stove surface, 1-2 is the burner, 1-3 is the pressure plate, and 1-4 is the energy-saving pot. The energy-saving pot support legs 1-4-1 and the pot legs 1-4-2 are welded to the energy-saving pot 1-4.

[0003] Figure 1 The area marked 2 on the left is a large flat-bottomed pan, typically over 30cm in diameter, which is rarely used in homes but is used as a standard for testing thermal efficiency in China. The combustion exhaust outlet is at a height 'a' of the pan legs 1–4–2, only about 10mm high. The amount of combustion exhaust flowing out is equal to the total amount of internal and external combustion gas, internal and external primary air, and internal and external secondary air. The high-temperature, viscous exhaust gas flowing along with the combustion exhaust is blocked and can only circulate within the space between the energy-saving basin 1–4 and the large flat-bottomed pan 2. This raises the temperature inside the energy-saving basin, reduces the heat loss from the flame contacting the cold air, and thus improves the measured thermal efficiency.

[0004] Let's look again. Figure 1 On the right, the arrangement of the round-bottomed pot 3 is illustrated. The distance b between the bottom of the pot and the outer edge of the energy-saving basin 1-4 is large, allowing a large amount of cold air to flow in from the edge of the basin. The viscous exhaust gas, heated by the flame, flows out with the combustion exhaust, carrying away heat. Therefore, when using the round-bottomed pot 3, the energy-saving basin 1-4 is essentially ineffective. Furthermore, the pot's legs are welded to the energy-saving basin; the heat from the flame heating the pot legs is transferred to the basin for dissipation, wasting heat. This is why modern gas stoves use a less stable four-legged pot rack to improve heat detection efficiency. Since the energy-saving basin 1-4 is made of a single layer of steel plate, it dissipates a lot of heat outwards, especially at high temperatures, where outward heat radiation loss is much greater than air convection heat loss, further reducing heat detection efficiency.

[0005] To further improve both the thermal efficiency of the test and the practical thermal efficiency of using a round-bottomed wok, the inventors filed two applications in July 2025, entitled "An Energy-Saving Wok Rack for a Round-Bottom Wok" and "A Multi-Layer Energy-Saving Furnace." During the research and development process, several other shortcomings of existing gas stoves were discovered, prompting continued development. In early November of the same year, a patent application for "A High Thermal Efficiency Gas Stove with Full Top Air Intake" was filed. After 3D-printed parts were sampled, both self-tested thermal efficiency and simple water-boiling tests with the actual wok showed significant improvements over various existing stoves on the market. However, it was found that the "multi-layer energy-saving furnace" increased the cost due to the added outer chamber and lower aluminum foil, and also made the appearance bulkier. Furthermore, it primarily improved the thermal efficiency over long periods, with little impact on the practical thermal efficiency for short-term cooking. Therefore, further improvements were made based on this design. Summary of the Invention

[0006] Based on the above background technology, the purpose of this invention is to improve the appearance, simplify the structure and reduce manufacturing costs, while still maintaining high thermal efficiency.

[0007] To achieve the above objectives, the present invention provides an infrared reflective heat insulation and energy-saving basin device, comprising: The energy-saving basin is divided into several parts. The lower part of the basin is shaped like a concave annular basin with a hole in the middle. It fits over the outer burner cap of the gas stove and has several support legs that rest on the stove surface. The lower edge of the basin is flat, and then the outer ring of the energy-saving basin is round. Finally, a reinforced edge is made at the top to form the upper edge of the energy-saving basin. A flat-bottomed pan rack is suitable for both flat-bottomed and round-bottomed pans. It includes a pan rack ring and several pan feet. The pan rack ring is placed inside the edge of the energy-saving basin, and the pan feet extend out of the pan rack ring and rest on the upper edge of the energy-saving basin. An aluminum foil basin, similar in shape to the energy-saving basin, completely covers the visible inner surface of the energy-saving basin, with its lower edge resting on the lower edge of the energy-saving basin.

[0008] As described above, in the infrared reflective heat insulation and energy-saving basin device, the aluminum foil basin turns upward from the lower edge to form the upper aluminum foil basin outer ring, which passes through the gap between the pot frame ring and the energy-saving basin outer ring to the upper edge of the energy-saving basin.

[0009] As described above, in the infrared reflective heat insulation and energy-saving basin device, the upper edge of the flat-bottomed pan support is divided into inner and outer sections. The outer section is horizontal, while the inner section is tilted downwards at a small angle.

[0010] As described above, in the infrared reflective heat insulation and energy-saving basin device, the inner edge of the flat-bottomed pan support leg is machined into an upward-pointing sharp angle.

[0011] As described above, the infrared reflective heat insulation and energy-saving basin device has a positioning plate on the upper part of the outer side of the flat-bottomed pan rack.

[0012] The infrared reflective heat insulation and energy-saving basin device described above also includes a positioning air inlet ring, which is installed under the energy-saving basin. It has several protrusions that connect to the energy-saving basin and form an air inlet slit. Its inner hole is precisely positioned outside the burner head under the gas stove burner cover.

[0013] In the infrared reflective heat insulation and energy-saving basin device described above, the positioning air intake ring is made of bright aluminum alloy.

[0014] As described above, the present invention simplifies and reduces the size of the furnace by removing the outer chamber and the original lower aluminum foil basin from the previous application entitled "A Multi-Layer Energy-Saving Furnace". However, after improvements in other aspects, it still has good heat preservation performance and maintains high thermal efficiency. The aluminum foil basin also has a protective function for the energy-saving basin. Because the temperature of the energy-saving basin is high, soup and oil stains that overflow and dry are difficult to clean. The aluminum foil basin has a very low value and can be replaced with a new one. Attached Figure Description

[0015] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings, wherein: Figure 1 This is a side sectional view of a gas stove with a single-layer energy-saving basin, showing a working diagram with a large flat-bottomed pan on the left and a wok on the right.

[0016] Figure 2 This is a side sectional view of the applicant's application entitled "A Multi-Layer Energy-Saving Furnace". The left display device uses a flat-bottomed pan, and the right display device uses an energy-saving pot rack for a round-bottomed frying pan.

[0017] Figure 3 This is a side cross-sectional view of the "Infrared Reflective Heat Insulation and Energy Saving Basin Device" of the present invention. The left display device uses a flat-bottomed pot rack, and the right display device uses a round-bottomed wok with an energy-saving pot rack. Detailed Implementation

[0018] Please see Figure 2 The main components of this multi-layered energy-saving furnace are: and Figure 1Similar to the previous section, 1 represents the gas stove section, 1-1 the gas stove surface, 1-2 the burner, 1-3 the pressure plate, 2 the frying pan, and 3 the round-bottomed frying pan. 4 is the multi-layered energy-saving combustion chamber, where 4-1 is the outer chamber, 4-2 the inner chamber, 4-3 the upper aluminum foil tray, and 4-4 the lower aluminum foil tray; 5 is the frying pan rack, where 5-1 is the frying pan rack foot and 5-2 is the frying pan rack ring; 6 is the round pot rack, where 6-1 is the round pot rack foot and 6-2 is the round pot rack ring. Using the round pot rack allows the combustion chamber to function, saving gas and increasing heat, with a difference of approximately 10% to 15%. Analysis suggests that when the gas stove is first ignited, the inner bore 4-2 and outer bore 4-1 are in a cold state and slowly heat up. The entire interior is in a state of maximum outward heat transfer, and there is no heat insulation between the inner and outer bores. Therefore, the heat insulation effect of the outer bore 4-1 and the lower aluminum foil pan 4-4 is very small when cooking for a short time. The main purpose is to improve the thermal efficiency of the large flat-bottomed pan for a long time, but it makes the structure complicated, increases the cost and affects the appearance, and has little practical value. Therefore, it can be removed.

[0019] Figure 3 This is a side sectional view of the "Infrared Reflective Heat Insulation and Energy Saving Basin Device" of the present invention, wherein... Figure 1 As shown in the diagram, 1 represents the gas stove section, 1-1 represents the gas stove surface, 1-2 represents the burner, here 1-2-1 represents the outer ring of the burner head, 1-2-2 represents the outer flame cap, 1-3 represents the pressure plate, 2 represents the flat-bottomed pan, and 3 represents the round-bottomed frying pan.

[0020] 7 is the energy-saving basin part, 7-1 is the energy-saving basin body, which is an annular concave basin with a hole in the middle 7-2. It is fitted over the outer burner cap 1-2-2 of the gas stove. Several support legs 7-3 are fitted with rubber sleeves 7-4 and rest on the stove surface 1-1. The edge of the energy-saving basin body 7-1 is the horizontal lower edge of the energy-saving basin 7-5, and then upwards is the round tubular energy-saving basin ring 7-6. At the top, it is reinforced to form the upper edge of the energy-saving basin 7-7.

[0021] On the left is the pan rack 8, which consists of a pan rack ring 8-1 and several pan feet 8-2. The outer diameter of the pan rack ring 8-1 is smaller than the inner diameter of the energy-saving basin ring 7-6. The pan feet 8-2 extend beyond the pan rack ring 8-1 and rest on the upper edge 7-7 of the energy-saving basin. Like a regular stove, this pan rack can also be used to cook with round-bottomed pans.

[0022] Here on the right is a round pot rack 9, similar to the flat-bottomed pot rack on the left. It consists of a round pot rack ring 9–1 and several round pot feet 9–2. The outer diameter of the round pot rack ring 9–1 is smaller than the inner diameter of the energy-saving basin ring 7–6. The lower part is inserted into the energy-saving basin ring 7–6. There are also round pot feet 9–3 that rest on the upper edge 7–7 of the energy-saving basin.

[0023] 10 is an aluminum foil basin, similar in shape to the energy-saving basin 7, completely covering the visible inner surface of the energy-saving basin 7. The lower edge 10-1 of the aluminum foil basin rests on the lower edge 7-6 of the energy-saving basin, then turns upward to form the outer ring 10-2 of the upper aluminum foil basin, passing through the gap between the outer edge of the pot rack ring 8-1 or 9-1 and the inner edge of the energy-saving basin 7-6, until it reaches the upper edge 7-7 of the energy-saving basin. In this way, the upper aluminum foil basin 10 can not only reflect infrared rays to improve thermal efficiency, but also protect the energy-saving basin 7. Because it is close to the flame, without the aluminum foil basin 10, even using a frying pan, the radiant heat can heat the energy-saving basin to a temperature exceeding 100°C. If soup is accidentally splashed into the basin, it will dry and be difficult to clean. However, the aluminum foil basin is of very low value and can be discarded and replaced.

[0024] To facilitate stacking and transportation, the outer ring 10-2 of the aluminum foil basin is made into a conical shape, wider at the top and narrower at the bottom. Therefore, the gap between the outer diameter of the flat-bottomed pot support ring 8-1 and the inner diameter of the energy-saving basin ring 7-6 needs to be relatively large. Consequently, several centering plates 8-3 are installed on the upper part of the outer edge of the pot support ring 8-1, and the lower outer edge is chamfered. The function of the outer ring 10-2 of the aluminum foil basin is to prevent heat radiation from the high-temperature pot support 8 to the energy-saving basin 7, thus reducing thermal efficiency. Increasing the gap also helps to reduce air heat transfer.

[0025] The pan support legs 8-2 are divided into two sections: the outer section 8-2-1 is the horizontal surface for resting the pan, and the inner section 8-2-2 is tilted downwards at a slight angle. This is mainly because most pans have a bottom that bulges downwards in the middle.

[0026] The inner edge of the 8–2–2 section of the flat-bottomed pan support leg is machined into a pointed shape. This is mainly to reduce the reduction in thermal efficiency caused by the pan legs lowering the heat-receiving area of ​​the pan bottom.

[0027] Below the energy-saving basin 7, a positioning air intake ring 11 is also installed. Several protrusions 12 on the ring connect to the energy-saving basin 7, forming an outer secondary air intake slit 13. An inner hole 11-1 is also machined to fit precisely onto the outer ring 1-2-1 of the burner head under the gas stove burner cap. Made of bright aluminum alloy, it improves thermal efficiency. Because the energy-saving basin has a high temperature and radiates heat outwards, the bright aluminum alloy reflects infrared rays back into the basin, reducing heat loss and increasing the internal temperature, thus improving thermal efficiency. Additionally, the secondary air entering through the slit 13 can be heated, recovering some heat and further improving thermal efficiency.
