Description

Technical Field

[0001] The utility model relates to a cooking appliance component and a cooking appliance, in particular to an anti-overflow pot cover and an anti-overflow pot. Background Art

[0002] A pot is a commonly used cooking appliance that can perform various cooking operations such as cooking, boiling, frying, and stir-frying on food. Currently, the pots on the market usually include a pot body and a pot cover placed on the pot body. The shape of the pot body is mostly circular and concave, and the material is mostly iron.

[0003] When in use, the pot is prone to the phenomenon of overflowing. The overflowing phenomenon often occurs in the later stage of scenarios such as cooking porridge or noodles when the liquid level in the pot body boils violently. At this time, water and starch are fully mixed to form a relatively viscous mixture, and a large amount of water vaporizes into water vapor and forms a large number of bubbles. However, the surface tension and viscosity of the formed viscous mixture are both greater than those of water. The bubbles are difficult to rise to the liquid surface and are also difficult to burst. Eventually, a large amount of accumulation leads to the overflowing phenomenon. At this time, the user usually has to spend energy adjusting the heat or the pot cover, resulting in a greatly increased complexity of operation. Therefore, it is urgent to develop an anti-overflow pot cover.

[0004] Existing anti-overflow pot covers usually have ventilation holes for discharging water vapor and heat to reduce the occurrence rate of the overflowing phenomenon, but there are the following deficiencies: 1) If the inner diameter of the ventilation hole is too large, foreign objects are extremely easy to fall into the pot body, which is inconvenient to use and reduces the aesthetic degree; at the same time, if the liquid in the pot body has not reached the boiling point, water vapor can be discharged through the ventilation hole, and heat is also dissipated accordingly, which is likely to cause an extended heating time required for the food in the pot body, resulting in a waste of energy; 2) If the inner diameter of the ventilation hole is too small, both its anti-overflow effect and safety are reduced. Summary of the Utility Model

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] During the cooking process, if the soup or porridge in the pot continues to rise due to boiling liquid level and contacts the two metal electrodes, an electric current will be generated between the two metal electrodes. After the current is detected by the control unit, the motor starts to rotate, and the fan connected to the motor will blow air into the pot. The fast-flowing air takes away the heat, causing the boiling liquid level in the pot to drop, thereby preventing the soup or porridge from overflowing. When the liquid level of the soup or porridge drops to a certain height, the fan will automatically stop working. If the liquid level of the soup or porridge rises to a preset height again, the fan will work again. The utility model has a built-in battery, does not require manual operation, has a good anti-overflow effect, and has high safety and convenience. BRIEF DESCRIPTION OF THE DRAWINGS
