Description

[Technical Field]

[0001] The present invention relates to the field of cooking appliances, and more particularly to a pot lid with a water circulation function, which is used for condensing and circulating steam, thereby reducing evaporation and steam pressure during the cooking process, improving cooking efficiency, and reducing fuel consumption. [Background technology]

[0002] When using traditional pots, the ingredients release a large amount of steam during the long simmering process, which can easily escape from the edge of the pot lid, causing excessive evaporation of the soup and requiring constant replenishment. This can also alter the original flavor and affect the cooking results. Meanwhile, using a traditional sealed pressure cooker can create too much pressure, leading to the risk of explosion. Furthermore, the escape of steam can fill the kitchen with the aroma of the soup, causing unnecessary environmental problems.

[0003] Therefore, it is necessary to design a pot lid that can effectively control steam inside the pot, i.e., a pot lid that can condense steam into droplets and return them to the pot, reducing steam leakage while avoiding the safety risk of pressure cooker explosion.

[0004] Due to the inability to effectively solve or overcome the problems of the above-mentioned prior art, the creator of this invention applied for this invention based on his many years of personal practical experience and long-term in-depth research, utilizing his knowledge of various water circulation pot lids, to solve the above-mentioned problems. Summary of the Invention [Problem to be solved by the invention]

[0005] The main purpose of this invention is to provide a water circulation pot lid that effectively reduces steam leakage and avoids the need for frequent water replenishment by condensing steam into droplets when it comes into contact with the pot lid and circulating the water back into the pot.

[0006] Specifically, the technology of this invention is to provide a water-circulating pot lid that, by designing the structure and material properties of the pot lid, can condense and circulate the steam generated by heating the soup in the pot, thereby reducing steam leakage, improving cooking efficiency, saving fuel, and preserving the flavor of the ingredients.

[0026] As shown in Figures 1, 2, 5, and 6, in the first embodiment of the present invention, the water circulation pot cover 100 mainly comprises a cover 10, a handle 20, a cold water injection hole 30, a drain hole 40, and a bottom plate 53. The cover 10 is for containing water and includes the handles 20 symmetrically arranged on both sides of the cover 10, a cold water injection hole 30 on one side of the cover 10 for injecting cold water, a drain hole 40 on the other side of the cover 10 for draining excess water, and a bottom plate 53 sealed at the bottom of the cover 10. The bottom plate 53 may be an upper arc-shaped bottom plate. The water circulation pot lid 100 is characterized by reducing steam leakage from the pot 60 by forming a water circulation process in which steam comes into contact with the pot lid 100, condenses into water, and the water droplets return to the pot 60.

[0027] As shown in FIG. 1, in the embodiment of the present invention, the material of the cover 10 is aluminum, aluminum alloy, or stainless steel to improve the heat conduction efficiency.

[0028] As shown in FIG. 1, in the embodiment of the present invention, the cold water injection hole 30 is connected to a first water pipe 35 that maintains the level of cold water to reduce the surface temperature of the bottom plate 50 .

[0029] As shown in FIG. 1, in this embodiment of the present invention, a second water pipe 45 is connected to the drain hole 40 to prevent the water level from overflowing.

[0030] As shown in Figures 1, 5 and 6, in one embodiment of the present invention, steam first rises upward and comes into contact with the low-temperature pot lid bottom plate 50, transferring heat to the water above. In the upper water portion, cold water circulates downward and hot water circulates upward, keeping the temperature of the pot lid bottom plate 50 low. When steam comes into contact with the lid bottom plate 50, it immediately drops in temperature and turns into water, which condenses on the lid bottom plate 50, forming droplets that fall. The rapid formation of water droplets by the steam delays the buildup of pressure inside the pot and also reduces the rate at which steam leaks out. Therefore, this cold water injection hole 30, connected to the first water pipe 35, maintains the cold water level, reduces the loss of water due to soup evaporation, effectively reduces the loss of steam, and stabilizes the temperature and pressure inside the pot 60.

[0031] As shown in Figures 1, 3, 5, and 6, in the second embodiment of the present invention, a water circulation pot lid 100 mainly comprises a lid body 10, a handle 20, a cold water injection hole 30, a drain hole 40, and a base plate 51. The lid body 10 is for containing water and includes handles 20 symmetrically arranged on both sides of the lid body 10, cold water injection holes 30 on the side of the lid body 10 for injecting cold water, the cold water injection hole 30 connected to a first water pipe 35 that maintains the cold water level to reduce the surface temperature of the base plate 51, a drain hole 40 on the other side of the lid body 10 for draining excess water, and a base plate 51 that is connected to a second water pipe 45 to prevent the water level from overflowing and is hermetically connected to the bottom of the lid body 10, which may be a flat base plate. The water circulation pot lid 100 is characterized by reducing steam leakage from the pot 60 by forming a water circulation process in which steam comes into contact with the pot lid 100, condenses into water, and the water droplets return to the pot 60.

[0032] As shown in Figures 1, 4, 5, and 6, a water circulation pot cover 100 according to a third embodiment of the present invention mainly comprises a cover 10, a handle 20, a cold water inlet 30, a drain hole 40, and a base plate 52. The cover 10, which is used to store water, includes handles 20 symmetrically arranged on both sides of the cover 10, a cold water inlet 30 on one side of the cover 10 for injecting cold water, a first water pipe 35 for maintaining the cold water level to lower the surface temperature of the base plate 52, a drain hole 40 on the other side of the cover 10 for draining excess water, and a base plate 52 sealed to the bottom of the cover 10 and connected to a second water pipe 45 for preventing water overflow. The base plate 52 may be a bottom plate with a downward arc. The water circulation pot lid 100 is characterized by reducing steam leakage from the pot 60 by forming a water circulation process in which steam comes into contact with the pot lid 100, condenses into water, and the water droplets return to the pot 60.

[0033] As shown in Figures 1, 5 and 6, in the embodiment of the present invention, the water circulation pot cover 100 can effectively reduce the steam leakage and stabilize the temperature and pressure inside the pot 60.

[0034] As shown in Figures 1, 5 and 6, in an embodiment of the present invention, the water circulation pot lid 100 is designed with a non-sealing structure so that it automatically releases steam to reduce the pressure inside the pot 60 if the pressure becomes excessive.

[0035] As shown in Figures 1, 5 and 6, in the embodiment of the present invention, the water circulation pot cover 100 can keep the water circulation in the pot 60 and reduce the water loss caused by the evaporation of the soup.

[0036] Through the above structure, this device has the function of condensing and refluxing steam: when steam comes into contact with the bottom of the pot lid, it is immediately condensed into water, which then drips into the pot, realizing the circulation of steam and reducing steam leakage. Save fuel: It reduces the evaporation rate of the soup, so there is no need to replenish water frequently during the process, which can effectively save fuel such as gas. Preserves the flavor of ingredients: Reducing the evaporation of soup can help preserve the original flavor of ingredients, making cooked food more delicious. Prevents burning: The pot lid design can prevent excessive evaporation of soup caused by overcooking, thereby significantly reducing the risk of burning and reducing the risk of fire. High safety: The automatic pressure regulation function in the pot prevents excessive pressure and reduces the risk of explosions like those caused by pressure cookers. Environmentally friendly: It prevents the smell of soup in the pot from escaping into the kitchen, thereby keeping the air in the kitchen clean. It meets the needs of modern technology, practicality and users, and can fully provide its positive aspects.
