Description

A top-mounted multifunctional air fryer and its heating cover

technical field

The invention relates to the technical field of kitchen appliances, in particular to a top-mounted multifunctional air fryer and a heating cover thereof.

Background technique

The air fryer is a household appliance that can use air to "fry". It mainly uses hot air to replace the hot oil in the original frying pan to make the food cooked; at the same time, the hot air is used to take away the moisture on the surface of the food. Make the ingredients similar to frying. The air fryer generates hot air by heating the heat pipe inside the machine at a high temperature, and then blows the high-temperature air into the country to heat the food with a fan. The hot air circulates in the enclosed space, and the food itself is used to fry the food, thereby dehydrating the food. , the surface is golden and crispy.

However, air fryers are generally relatively large in size and occupy a high proportion of space, but have relatively single functions and poor user experience. To this end, Chinese invention patent CN112155438A provides a multi-functional air fryer, including a lower pot body, which is provided with a lower heat radiation heating component; an upper pot body, which is provided with a hot air convection component, and the upper pot body can The lid of the pot body is closed or separated. When the upper pot body and the lower pot body are closed, an air fryer cavity can be formed. The lower heat radiation heating component and the hot air convection component cooperate to air fry the ingredients in the air fryer cavity; When the body is separated, the upper pot body can avoid the upper part of the lower pot body, so that the lower pot body forms a cooking cavity with the opening facing upward; the cooking utensils can be arranged in the air fryer cavity or the cooking cavity for accommodating the cooking cavity to be cooked. prepared food.
