Description

Technical Field

[0001] This utility model relates to the field of electric cooker technology, and in particular to an electric cooker that can recycle waste heat. Background Technology

[0002] Electric cookers are common household appliances with a variety of basic cooking functions, such as boiling, stewing, making porridge, and hot pot. Some models are equipped with a steaming rack. The operation is mostly adjusted by knobs or buttons. They have a compact structure and are suitable for small spaces such as rented rooms and dormitories. They are a common cooking tool for single people and students.

[0003] Electric cookers, as convenient small cooking appliances, have various functions such as boiling, stewing, steaming, and hot pot. However, most current products do not have a dedicated waste heat collection component. After heating, a large amount of waste heat stored in the heating element and the pot body is directly dissipated into the surrounding environment and cannot be effectively recovered and utilized, resulting in low heat utilization rate and energy waste. At the same time, due to the lack of a waste heat reuse mechanism, electric cookers cool down quickly after heating stops, and cannot continuously keep the food inside warm. Especially in low-temperature environments or when long-term storage is required, the food is prone to affecting the taste and eating experience due to temperature drop, making it difficult to meet users' actual needs for food heat preservation.

[0004] Therefore, it is necessary to invent an electric cooker that can recycle waste heat to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an electric cooker that can recycle waste heat, in order to solve the problem mentioned in the background art that existing electric cookers, as convenient small cooking appliances, have multiple functions such as boiling, stewing, steaming, and hot pot. However, current products generally do not have a dedicated waste heat collection component. After heating, a large amount of waste heat stored in the heating element and the pot body is directly dissipated into the surrounding environment and cannot be effectively recycled, resulting in low heat utilization and energy waste. At the same time, due to the lack of a waste heat reuse mechanism, the electric cooker cools down quickly after heating stops, and cannot continuously keep the food inside warm. Especially in low-temperature environments or when long-term storage is required, the food is prone to affecting the taste and eating experience due to temperature drop, making it difficult to meet users' actual needs for food heat preservation.
