Description

Technical Field

[0001] This invention relates to the field of food steaming equipment technology, specifically to a steamer that is adaptable to different stoves, uses fixed low water level heating, has an automatic water replenishment function, ensures even cooking of food, and is energy-saving. 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 fix the heating water level between 5 mm and 15 mm, allows food to be heated quickly and evenly, and can automatically maintain this state until it is fully cooked.

[0004] Figure 1 This is a schematic diagram illustrating the structure and usage of the present invention; Figure 2This is a partial detailed schematic diagram of the water inlet guide tube elbow 6 of the present invention connecting and extending into the pot body 9; Figure 3 This is a schematic diagram of the bottom ventilation holes of the uniform cooking energy-saving steamer 7 of the present invention. Detailed Implementation

[0005] 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 9 primarily functions to hold a small amount of water to be heated, generate or transfer heat, and provide connection and support to the energy-saving steamer 7. It has the energy-saving steamer 7 on top, and an exhaust vent 11 located in the upper or middle part of one side. On the other side, in the middle or upper part, it connects to the water inlet pipe elbow 6; the energy-saving steamer 7 ( 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 1 represents a small hole (the shape, size, and number of holes are not limited), or similar small holes are densely distributed around the perimeter. Its main function is to allow steam to pass through quickly, securely, and without deformation after food or a plate is placed on it. A non-porous transparent lid 8 covers the lid. The non-porous transparent lid 8's main function is to block and suppress steam, allowing the viewer to see the food's doneness. The vent 11 has a diameter between 6 mm and 15 mm (preferably 10 mm). Its main function is to keep the space between the non-porous transparent lid 8 and the vent 11 filled with higher-temperature steam, allowing only lower-temperature steam to escape. The water inlet pipe elbow 6's main function is to deliver replenishing water and fix the heating water level. The balance distance from one end of the water inlet extending into the pot body 9 to the bottom of the pot is between 5 mm and 15 mm (preferably 7 mm), with the other end slightly upwards. The flexible conduit 4 is connected to the water supply tube 4 at an angle. The main function of the flexible conduit 4 is to transport replenishment water and keep the sealed water tank 1 away from the high-temperature heat source to reduce costs (e.g., using a plastic drinking water bottle as the sealed water tank 1). The other end is slightly angled upwards and connected to the outlet conduit elbow 3. The main function of the outlet conduit elbow 3 is to transport water. The other end is connected upwards to the outlet of the sealed water tank 1 (the cap-in-cap of the plastic drinking water bottle) (easily pluggable type with a sealing gasket or simple knob type). The main function of the sealed water tank 1 is to add equipment water (total water required for heating and evaporation and excess water) and continuously replenish water to the pot body 9 automatically. It is supported by a bracket 2 below. The main function of the bracket 2 is to facilitate insertion, removal, support, and stabilization of the sealed water tank 1 and to maintain a gradual rise in the water path from the inlet to the outlet to stabilize automatic water replenishment. In addition, all components are heat-resistant. The operating steps of this invention are as follows: First, for first use, follow the instructions. Figure 1First, assemble and arrange the sealed water tank 1, bracket 2, outlet pipe elbow 3, flexible pipe 4, operating platform 5, inlet pipe elbow 6, pot body 9, and stove 10; Second, pull out the outlet pipe elbow 3; Third, lift and remove the sealed water tank 1, and open the lid ( Figure 1 The blue lid in the middle is a lid with internal threads, a sealing gasket, and a lid-within-a-lid. Fill it with water, close the lid-within-a-lid (remove the outer dust cover if there is one for first use), and close the inner lid tightly. Fourth, put the support 2 back. Fifth, insert the water outlet tube elbow 3 (with the silicone sleeve on) until the lid-within-a-lid is fully opened or half-opened, and water can flow normally. Sixth, when the water in the pot body 9 has completely filled the bottom of the pot and no more water is coming in, check to ensure that there is no air or water leakage in the water path from the pot body 9 to the sealed water tank 1. Seventh, adjust the stove 10 or operating platform 5 to balance the water level in the pot body 9, so that one side is not higher than the other. Eighth, confirm or adjust the pot body 9 to be in the appropriate heating zone of the stove 10, so that it is not too off-center. Ninth, place the food-filled evenly cooked section on top. After steaming the rice in steamer 7, cover it with the non-perforated transparent pot lid 8; turn on the stove 10 at the highest setting or power (if using a gas stove, to save energy, only turn on the low flame, ensuring the flame does not exceed the bottom of the pot), and start heating; reduce the heating setting or power when a large amount of steam is rapidly discharged from the vent 11; if steaming more than two layers of steamers, stop reducing the heating setting or power when maintaining heating and boiling (listen to the sound); if steaming two or fewer layers of steamers, stop reducing the heating setting or power when a small amount of steam is slowly discharged from the vent 11 or when there is a brief pause in the rapid discharge (observe the steam); observe the rice under the non-perforated transparent pot lid 8 until it is fully cooked, then stop heating. The working principle of this invention is as follows: During the heating process, a small amount of water in the pot body 9 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 7. After reaching the non-porous transparent pot lid 8, it fills the space between the non-porous transparent pot lid 8 and the vent 11 from top to bottom, and then is discharged outward from the vent 11. At the same time, hot air rises and cold air descends and is discharged outward from the vent 11. As the water in the pot body 9 continues to evaporate, the water level gradually drops. When the water level drops to a certain distance (within 4 millimeters), the steam enters the sealed water tank 1 and is replaced by water to replenish it. The water level then gradually rises again, and the cycle continues.
