Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to an air fryer with high-efficiency heat utilization structure. BACKGROUND

[0002] The air fryer is a kitchen appliance that appeared in the early 21st century. It simulates the effect of oil frying through high-speed circulating hot air technology, so that food can achieve a crispy texture in a low-oil or oil-free state. The core structure of the air fryer mainly includes a heating element, a high-power fan and a food basket. The working principle of the air fryer is that the fan circulates the high-temperature air generated by the heating pipe in the pot to form a hot air flow. The special hollow design of the food basket ensures that hot air can penetrate the food, making its surface quickly dehydrate and crisp, simulating the crispy texture of oil frying, thereby achieving a healthy "frying" effect with less oil.

[0003] Now, the existing air fryers on the market have poor heat dissipation effect, or the heat dissipation structure is not compact enough, resulting in that the air fryer occupies a large size, causing space waste. At the same time, the existing national standard proposes a new air fryer heat dissipation standard, which limits that when the air fryer is spaced a certain distance from the wall, the wall needs to be below a certain temperature during the continuous heat dissipation process of the air fryer. The existing air fryers on the market mostly have poor heat dissipation effect, and the heat dissipation effect needs to be further improved.

[0024] Optionally, one end of the steam generating pipe 12 is communicated with the heat dissipation water tank 3, and the other end of the steam generating pipe is communicated with the cooking cavity 1. The water in the heat dissipation water tank 3 can flow into the steam generating pipe 12, and be converted from liquid water to water vapor under the heating of the heating pipe 11. The steam generating pipe 12 can be arranged adjacent to the heat source in the air fryer. The heat source in the air fryer can be a heat source for cooking and heating food. In addition to heating food for cooking, the heat source can also heat the steam generating pipe 12 to convert the water in the steam generating pipe 12 to water vapor, reducing heat waste in the heat propagation path and achieving efficient use of heat.
