Description

Technical Field

[0001] This invention relates to the field of food steaming and cooking appliances, specifically to a steamer that is adaptable to different stoves, uses adjustable low water level heating, has an automatic water replenishment function, ensures even cooking of food, and is water-saving and energy-efficient. Background Technology

[0002] The shortcomings of existing steamers can be summarized as follows: they generally have problems such as high heating water level, large water consumption, slow steam generation, and low heat utilization rate, resulting in high energy consumption during steaming and cooking. At the same time, they are prone to causing a large amount of steam and heat loss, which not only affects the even cooking of food, but also further reduces energy efficiency. In some cases, adding too little water can easily cause dry burning. The shortcomings of existing steamers are as follows: When using them, a large amount of water is typically boiled from the beginning and kept boiling until the food is fully cooked. This results in the food taking a long time to heat up, and even after it's cooked, there's often still a lot of water left in the steamer, or it may dry out completely (adding too much water wastes time and energy, while adding too little water risks damaging the steamer). Furthermore, the venting method and location are almost always at the top of the lid. This design means that when using a large steamer or multi-layered steamers, the heating power may be insufficient, leading to uneven heating, steam evaporation, and steam rising areas. This indirectly results in uneven heating and cooking of the food in the steamer or multi-layered steamers. Also, based on the principle of hot air rising and cold air sinking, the released steam is always at a relatively high temperature, causing waste. Summary of the Invention

[0003] This invention addresses the shortcomings of existing steamers (as described above) and provides a steamer that is compatible with different stoves, can adjust the heating water level to a low range of 4 mm to 10 mm, allows food to be heated quickly and evenly, and can automatically maintain this state until fully cooked. The steaming method is the opposite of the traditional one, only releasing low-temperature steam. It can also automatically replenish water, saving water and energy. To achieve the above objectives, the present invention comprises a sealed water tank 1, a non-sealed water tank 2, an air vent 3, a lifting platform 4, a flexible rubber tube 6, a high-temperature resistant tube 7, a steam vent 8, a non-porous transparent pot lid 9, a uniformly cooked energy-saving steamer 10, and a pot body 11. This assembly includes a low-water-level heating structure (composed of the sealed water tank 1, non-sealed water tank 2, air vent 3, lifting platform 4, flexible rubber tube 6, high-temperature resistant tube 7, and pot body 11, used to adjust and maintain the heating water level within a range of 4 mm to 10 mm to achieve energy saving), an automatic water replenishment structure (composed of the sealed water tank 1, non-sealed water tank 2, air vent 3, flexible rubber tube 6, and high-temperature resistant tube 7, used to automatically replenish water during steaming to maintain a stable low-water-level heating), and a uniformly cooked energy-saving venting structure (composed of the steam vent 8, non-porous transparent pot lid 9, uniformly cooked energy-saving steamer 10, and pot body 11, used to achieve high-temperature venting and low-temperature venting, reducing heat loss to ensure even cooking of food and energy saving). This invention significantly reduces the time food needs to be heated, and once the food is fully cooked, only a small amount of water remains in the steamer. By employing a low-water-level heating structure, the invention controls the heating water level within a smaller range, drastically reducing the amount of water required during heating and achieving significant water savings. Simultaneously, the lower water level shortens the time it takes for the water to boil, allowing heat to be more concentrated for steam generation, reducing ineffective energy consumption, improving thermal energy utilization, and achieving energy conservation. The automatic water replenishment device and water level control mechanism maintain a stable low-water-level heating state during steaming, eliminating the need for manual water addition and making it more convenient and reliable. The energy-saving exhaust structure effectively controls the amount of steam emitted, ensuring even heating and thorough cooking while minimizing steam and heat loss, further improving overall energy efficiency and achieving energy savings once again. This invention has a reasonable structure, reliable implementation, and strong practicality and promotional value.

Detailed Implementation The appearance and shape of this invention are not limited; the pot body can be round or square, but is generally round. For example... Figure 1 The pot body is 11mm thick and comes in two styles. Figure 1 It's a high-priced style. Figure 4 This is a low-priced model. Its main functions and uses are high temperature resistance, holding a small amount of water to be heated, heating or transferring heat, and connecting and supporting the uniform cooking energy-saving steamer. It has a uniform cooking energy-saving steamer 10 on top, a steam exhaust port 8 connected to the middle or upper part of the side, and a high-temperature resistant pipe 7 connected to the lower part of the side, almost near the bottom; the uniform cooking energy-saving steamer 10 ( Figure 3 (Details to be shown), there may be multiple, and the bottom is distributed with two types of ventilation holes (e.g.: Figure 3 The number 2 in the diagram represents a large hole. Figure 3 The number 1 in the designation represents a small hole; the shape, size, and number of holes are not limited. Its main functions are high temperature resistance, allowing steam to pass through quickly after food or plates are placed on it, and ensuring it is secure and does not deform. It is covered with a non-perforated transparent lid 9. The non-perforated transparent lid 9's main functions are high temperature resistance, blocking and suppressing steam, and allowing the viewer to see the food's doneness. The steam vent 8 comes in two styles. Figure 1 It's the high-priced model (with a spout-like shape). Figure 4 The lower-priced model (with several small holes arranged side-by-side in the middle or upper part of the side of the pot body 11) mainly functions to withstand high temperatures, keep the space between the bottom of the non-porous transparent pot lid 9 and the steam vent 8 filled with high-temperature steam, and ensure that the exhaust volume is sufficient to discharge only lower-temperature steam without backflow of the water supply; the high-temperature resistant pipe 7 mainly functions to withstand high temperatures and transport water supply, with the other end slightly angled downwards and connected to the flexible rubber pipe 6; the flexible rubber pipe 6 mainly functions to withstand high temperatures, transport water supply, keep the other components of the invention away from high-temperature heat sources to reduce costs (e.g., non-heat-resistant plastic sealed water tank 1, non-sealed water tank 2, lifting platform 4), and prevent water from spilling when the sealed water tank 1 is inserted (installed), with the other end connected to the side of the non-sealed water tank 2 near the bottom; the non-sealed water tank 2 ( Figure 2 (Details shown) The model in the picture is made from the lower half of a plastic bottle. The groove in the bottle body naturally forms a locking position to hold the sealed water tank 1 (also made of plastic bottle). The horizontal distance between the outlet (bottle mouth) of the sealed water tank 1 and the outlet (connection point with the flexible hose 6) of the unsealed water tank 2 is more than 10 mm to ensure stable water supply. The sealed water tank 1 is inserted upside down on top. Air vents 3 are distributed around the middle or upper part of the tank wall. It is supported by a lifting platform 4 below. Its main functions and purposes are to allow the sealed water tank 1 to be easily inserted and removed (removed), to support and stabilize the sealed water tank 1, and to receive and transport replenished water; air vents 3 ( Figure 2(Details shown). The shape, size, and number of holes are not limited. Their main function is to expel air and maintain the air and water in the non-sealed water tank 2 at normal pressure for stable automatic water replenishment. Sealed water tank 1, the model in the picture is made from a whole plastic bottle, inserted upside down on top of and inside the non-sealed water tank 2. Its main function is to add equipment water (total water required for heating and evaporation and excess water) and to automatically replenish water to the non-sealed water tank 2. Lifting platform 4's main function is to support the water tank and adjust and maintain its height to obtain a low water level (within the range of 4 mm to 10 mm) in the pot body 11. The operating steps of this invention are as follows: First, take out the sealed water tank 1, fill it with water, and then place it upright on the operating platform 5 between the stove 12 and the lifting platform 4; Second, first use one hand to pick up the non-sealed water tank 2 and place it upside down on top of the sealed water tank 1, then use the other hand to hold the non-sealed water tank 2; Third, first hold them simultaneously and lift them above the lifting platform 4, then quickly flip them 180 degrees and place them on the lifting platform 4; Fourth, while slowly raising the lifting platform 4 (the default initial state is at the lowest position), observe the water in the pot 11 until the water completely overflows the bottom of the pot and no longer... 1. Add water (observe the water inlet again) and stop adjusting the water level when it reaches 4 mm to 10 mm. 2. Place the food-filled, energy-saving steamer 10 on top, then cover with the non-porous transparent lid 9. 3. Turn on the stove 12 to the highest setting or power to start heating. 4. Reduce the heating setting or power when a large amount of steam is rapidly discharged from the steam exhaust port 8. 5. Stop reducing the heating setting or power when a small amount of steam is slowly discharged from the steam exhaust port 8. 6. Stop heating when the rice under the non-porous transparent lid 9 is fully cooked. The working principle of this invention is as follows: During the heating process, a small amount of water in the pot 11 is rapidly heated to form steam at a low water level. The steam rises and quickly passes through the multi-layer uniform cooking energy-saving steamer 10. After reaching the non-porous transparent pot lid 9, it fills the space between the non-porous transparent pot lid 9 and the steam exhaust port 8 from top to bottom, and then is discharged from the steam exhaust port 8. As the water in the pot 11 continues to evaporate, the water level in the non-sealed water tank 2 gradually decreases in conjunction with the water level. When the water level drops to a certain distance (within about 4 millimeters), air enters the sealed water tank 1 and is replaced by water flowing out to replenish it. The water level then gradually rises again, and the cycle continues.
