Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, and particularly to a water vapor condensation and reflux pot cover based on an anti-overflow sealing structure. Background Art

[0002] Cookware is a commonly used kitchen utensil in people's lives. People usually use cookware to cook soups or porridges. During this process, the liquid in the pot often overflows due to boiling, splashing onto the pot body and the stove top, which is not easy to clean. Especially when people are not paying attention or forget, the overflowing liquid will extinguish the gas stove, causing safety accidents such as natural gas leakage and fire, presenting certain safety hazards.

[0003] To solve this problem, most cookware is provided with ventilation holes, but the ventilation holes are small and the anti-overflow effect is poor. It is still necessary to manually open the lid to prevent the liquid from overflowing, which requires people to always stay in front of the stove, which is rather inconvenient. There are also some pot covers provided with annular grooves for anti-overflow, which does have a certain effect, but the cleaning is really troublesome.

[0004] A kind of anti-overflow pot cover recorded in the patent with the Chinese patent publication number: CN218606193U. By making the weight of the secondary cover greater than the weight of the anti-overflow cover, it can ensure that the anti-overflow cover seals the anti-overflow hole, maintaining the heat and moisture in the pot. When the pressure in the pot increases and the liquid in the pot boils and foams and is about to overflow, the secondary cover is pushed up to make the anti-overflow cover descend to expose the anti-overflow hole, reducing the pressure in the pot and preventing the liquid in the pot from overflowing. The lower surfaces of the lid body, the secondary cover and the anti-overflow cover are all concave surfaces, so that the water vapor in the pot can condense and flow back into the pot after condensation.

[0005] However, although the anti-overflow hole provided in this pot cover can reduce the pressure in the pot, it also makes the moisture in the ingredients easily evaporate and lose through the anti-overflow hole at high temperature. This not only affects the cooking effect, increases the difficulty of moisture management during the cooking process, but also may cause the ingredients to lose their original tender taste due to excessive evaporation and become dry and tasteless. In addition, the rapid evaporation of moisture also wastes energy, prolongs the cooking time, and reduces the cooking efficiency. Content of the Utility Model

[0006] Aiming at the above problems, a water vapor condensation and reflux pot cover based on an anti-overflow sealing structure is provided, which solves the problem of reduced cooking efficiency caused by the loss of moisture in the ingredients by setting a reflux component.

[0007] To solve the problems of the prior art, the utility model provides a water vapor condensation and reflux pot cover based on an anti-overflow sealing structure, including an upper cover and a lower cover connected to the upper cover. The upper cover is provided with an exhaust chamber for discharging excess water vapor.

[0008] The exhaust chamber is also provided with a reflux assembly for condensing and refluxing water vapor. The reflux assembly includes a condensation chamber disposed at the upper end of the exhaust chamber and communicating with the same to collect and condense the rising water vapor.

[0009] The lower cover includes a cover edge for stably placing it on the pot edge, and a deflector plate for guiding the reflux of condensed water vapor is provided on the inner wall of the cover edge.

[0010] Preferably, the inner wall of the upper cover is a slope for promoting the flow of condensed water.

[0011] Preferably, at least one reflux hole is further provided in the exhaust chamber. The reflux hole connects the condensation chamber and the inner space of the pot to allow the condensed water to flow back into the pot.

[0012] Preferably, the deflector plate is inclined to facilitate the reflux of condensed water.

[0013] Preferably, a connecting plate is connected to the lower end of the deflector plate, and a plurality of bubble-breaking holes are provided on the connecting plate, and the bubble-breaking holes are distributed in a divergent manner.

[0014] Preferably, a plurality of connecting blocks are provided at the lower end of the upper cover, and connecting grooves matching the connecting blocks are provided at the upper end of the lower cover.

[0015] Preferably, a handle is further provided on the upper cover, and a heat insulation material for reducing heat transfer to the user's hand is provided in the handle.

[0016] The beneficial effects of the present utility model compared with the prior art are as follows:

[0017] 1. Through the slope provided on the inner wall of the upper cover of the present utility model, the evaporated and lost water is preliminarily recovered, and then through the condensation chamber, the water in the excess gas is condensed and refluxed during the exhaust process, effectively reducing the loss of water in the pot body and improving the cooking efficiency.

[0018] 2. By providing bubble-breaking holes on the connecting plate of the present utility model, when the liquid in the pot boils and foams, the bubbles are effectively broken, preventing the liquid from overflowing, and the food items driven by the bubbles can be blocked, thereby preventing the liquid from being carried out of the pot, and improving the anti-overflow and sealing function of the pot cover.

Detailed implementation manners

[0027] To further understand the features, technical means, and specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0028] See Figures 1-7 As shown, a steam condensation and reflux pot lid based on an anti-overflow sealing structure includes an upper cover 100 and a lower cover 101 connected to the upper cover 100. An exhaust chamber 401 for discharging excess steam is provided on the upper cover 100. A reflux assembly for condensing and refluxing the steam is further provided in the exhaust chamber 401. The reflux assembly includes a condensation chamber 412 provided at the upper end of the exhaust chamber 401 and communicating with it to collect and condense the rising steam. The lower cover 101 includes a lid edge 200 for stably placing it on the pot edge, and a deflector plate 201 for guiding the condensed steam to flow back is provided on the inner wall of the lid edge 200.

[0029] See Figure 2 、 Figures 5-7As shown, the inner wall of the upper cover 100 is a slope to facilitate the flow of condensed water. An installation hole 400 is provided at the upper end of the upper cover 100. An exhaust chamber 401 is provided in the installation hole 400. An installation disk 405 is provided in the exhaust chamber 401. A sliding groove 402 is provided on the inner wall of the exhaust chamber 401. A slider 403 is slidably provided inside the sliding groove 402. The slider 403 is arranged outside the top plate 404. A sliding rod 407 is provided at the upper end of the top plate 404. A sliding hole 406 matching the sliding rod 407 is provided on the installation disk 405. A through hole 408 for water vapor to pass through is also provided on the installation disk 405. A sealing plug 409 matching the through hole 408 is provided at the upper end of the sliding rod 407. A plurality of exhaust holes 410 are provided outside the condensation chamber 412. During use, the water vapor generated during the cooking process first contacts the upper cover 100, is initially condensed into water droplets, and then slides down along the slope to the pot edge due to gravity and drips back into the pot. As the steam continuously generated in the pot causes the pressure inside the pot to gradually increase, when the pressure increases enough to overcome the resistance of the top plate 404, the steam pushes the top plate 404 to move upward in the exhaust chamber 401, causing the sliding rod 407 to drive the sealing plug 409 to move upward, thereby opening the through hole 408 to discharge the excess water vapor into the condensation chamber 412, and then discharging it through the exhaust holes 410.

[0030] See Figure 6 As shown, at least one return hole 411 is further provided in the exhaust chamber 401. The return hole 411 connects the condensation chamber 412 and the space inside the pot to allow the condensed water to flow back into the pot. The return hole 411 is arranged at the edge position of the installation disk 405. During use, the excess water vapor enters the condensation chamber 412, the water vapor will further condense into water, and gradually accumulate at the bottom of the condensation chamber 412 as the condensation process continues. When the condensed water accumulates to a certain extent, it will naturally flow back into the pot through the return hole 411 and continue to participate in the cooking process, thus realizing the maximum utilization of water vapor resources.

[0031] See Figures 2-3 As shown, the guide vane 201 is inclined to facilitate the return of condensed water. The lower end of the guide vane 201 is connected with a connecting plate 202. A plurality of bubble-breaking holes 203 are provided on the connecting plate 202, and the bubble-breaking holes 203 are distributed in a divergent shape. During use, the condensed water generated by the upper cover 100 will be guided to the connecting plate 202 through the guide vane 201, and then flow back into the pot through the bubble-breaking holes 203. When the liquid in the pot boils and foams, the bubble-breaking holes 203 can quickly and effectively break the bubbles, preventing the liquid from overflowing along the gap between the lid edge and the pot body. When a large number of bubbles are generated when the liquid in the pot boils, these bubbles may drive the ingredients or other items to surge upward, increasing the risk of liquid overflow. At this time, through the cooperation between the connecting plate 202 and the bubble-breaking holes 203, the further movement of the items can be effectively blocked or slowed down, thereby preventing the liquid from being carried out of the pot and improving the anti-overflow sealing function of the pot lid.

[0032] See Figures 1-4 As shown, a plurality of connecting blocks 300 are provided at the lower end of the upper cover 100, and a connecting groove 301 matched with the connecting blocks 300 is provided at the upper end of the lower cover 101. During use, the upper cover 100 and the lower cover 101 are connected through the connecting blocks 300 and the connecting grooves 301.

[0033] See Figure 1 As shown, it further includes a handle 102 provided on the upper cover 100. The handle 102 is provided with heat insulation material that reduces heat transfer to the user's hand. Through the use of the heat insulation material, the degree of heat transfer from the pot lid to the user's hand can be effectively reduced, thus ensuring the safety of the user during long-term use or in a high-temperature cooking environment.

[0034] The above embodiment discloses a steam condensation and reflux pot lid based on an anti-overflow sealing structure. When this pot lid is in use, the upper cover 100 and the lower cover 101 are connected through the connecting blocks 300 and the connecting grooves 301. Then, the pot lid is placed on the pot body. When the liquid in the pot boils and foams, the bubble-breaking holes 203 can quickly and effectively break the bubbles, avoiding the overflow of the liquid along the gap between the lid edge and the pot body. When a large number of bubbles are generated when the liquid in the pot boils, these bubbles may drive the ingredients or other items to surge upward, increasing the risk of liquid overflow. At this time, through the cooperation between the connecting plate 202 and the bubble-breaking holes 203, the further movement of the items can be effectively blocked or slowed down, thereby preventing the liquid from being carried out of the pot, improving the anti-overflow sealing function of the pot lid. And the water vapor generated during the cooking process first contacts the upper cover 100, then is initially condensed into water droplets, and then slides down along the slope to the pot edge due to gravity and is guided to the connecting plate 202 through the flow guiding plate piece 201, and then flows back into the pot through the bubble-breaking holes 203. As the continuously generated steam in the pot makes the pressure in the pot gradually increase, when the pressure increases enough to overcome the resistance of the top plate 404, the steam pushes the top plate 404 to move upward in the exhaust chamber 401, so that the sliding rod 407 drives the sealing plug 409 to move upward, thereby opening the through hole 408 to discharge the excess water vapor into the condensation chamber 412. The excess water vapor enters the condensation chamber 412, and the water vapor will further condense into water and gradually accumulate at the bottom of the condensation chamber 412 as the condensation process continues. When the condensed water accumulates to a certain extent, it will naturally flow back into the pot through the return hole 411 and continue to participate in the cooking process, thus realizing the maximum utilization of water vapor resources. And the gas generated during the condensation process is discharged through the exhaust hole 410.

[0035] The above embodiments only represent one or several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the appended claims.
