Pot cover with cold gathering ring

By installing a cooling ring on the pot lid, heat is absorbed by phase change materials or hydrogel materials, causing hot water steam to liquefy and release heat energy. This solves the problem of slow heat dissipation of existing pot lids and achieves the effects of rapid heating and energy saving and emission reduction.

Description

TECHNICAL FIELD

[0001] The utility model relates to kitchen utensil equipment technical field, in particular to a pot cover with cold ring. BACKGROUND

[0002] The main role of the pot cover is to keep the temperature of the material in the pot, and prevent the liquid in the pot from splashing and the steam from escaping due to factors such as heating.

[0003] The existing ordinary pot cover will continue to emit heat after the pot is heated, which will cause the temperature in the pot to rise slowly, the food to be cooked slowly, and the heating time to be long, which is not conducive to energy saving and emission reduction. CONTENT OF THE UTILITY MODEL

[0004] The utility model discloses a kind of pot covers with cold ring, special cold ring is installed on pot cover, can effectively absorb heat, hot water vapor will expand and rise when high-temperature cooking in the pot until contact ice-cold pot cover, when water vapor temperature reduces to dew point, quickly change from gaseous state to liquid state, in this process, the distance between water vapor molecules reduces, potential energy between molecules is converted into heat energy release, this mechanism accelerates the cooking process of food in the pot, the temperature in the pot rises fast, food heating time is short, conducive to energy saving and emission reduction.

[0005] To achieve the above object, the technical scheme adopted by the utility model is as follows:

[0006] A kind of pot cover with cold ring, including pot cover main part, pot cover main part top surface middle is provided with pot knob, the top surface of the pot cover main part outside the periphery of the pot knob is provided with ring groove, and the detachable cold ring is arranged in the ring groove.Cold ring is clamped in ring groove by embedding.

[0007] As preferred, the top surface of the cold ring is provided with an outwardly protruding lifting block. This facilitates the removal of the cold ring when the utensil is not in use and its placement in the refrigerator for cooling and standby use.

[0008] As preferred, the main body material of the cold ring is a phase change material. The outside is a coating layer, and the inside is a phase change material. The phase change material is non-toxic, non-corrosive, low in cost, easy to manufacture, and has small expansion and contraction.

[0009] As preferred, the main body material of the cold ring is a hydrogel. The outside is a coating layer, and the inside is a hydrogel material. The hydrogel has two advantages of high thermal insulation performance and high water content. Its low thermal conductivity brings high thermal insulation performance, which can effectively prevent heat transfer and reduce heat loss. At the same time, it can absorb and retain a large amount of water, and use the latent heat of water evaporation to absorb surrounding heat to achieve cooling effect when absorbing heat.

[0010] As preferred, the number of ring grooves is one or more, and when there are multiple ring grooves, the ring grooves are arranged in concentric rings.

[0011] Preferably, the outline of the pot lid body is circular or square, and the outline of the annular groove is circular or square.

[0012] The beneficial effects of this utility model are as follows: 1. A special cooling ring is installed on the pot lid, which can effectively absorb heat. When the pot is cooked at high temperature, the hot water steam will expand and rise until it comes into contact with the cold pot lid. When the water steam encounters the cold and the temperature drops to the dew point, it will quickly change from a gaseous state to a liquid state. In this process, the distance between water vapor molecules decreases, and the potential energy between molecules is converted into heat energy and released. The heat released by liquefaction accelerates the vaporization rate of the liquid. The vaporization and liquefaction rates are much faster than those without a cooling ring. This mechanism accelerates the cooking process of food in the pot, the pot heats up quickly, and the food heating time is short, which is conducive to energy conservation and emission reduction.

[0013] 2. The cooling ring is located on the top surface of the pot lid, isolated from the inside of the pot, making it easy to disassemble and assemble in daily use and improving safety. Attached Figure Description
