Description

Technical Field

[0001] This utility model relates to the field of cooking appliance technology, specifically to a top cover assembly with a cooling air duct and a cooking appliance. Background Technology

[0002] An air fryer primarily uses air instead of the hot oil in a frying pan to gradually cook food. Simultaneously, the hot air removes surface moisture, achieving a similar effect to deep-frying. The basic working principle of an air fryer is "high-speed air circulation technology." Hot air is generated by heating elements inside the machine at high temperatures. A fan then blows this hot air into the fryer to heat the food. The hot air circulates within the enclosed space, using the food's own oils to fry it, thus dehydrating the food and resulting in a golden-brown, crispy surface, achieving a deep-frying effect.

[0003] In existing technologies, based on factors such as product design and aesthetics, some air fryers have decorative parts, especially metal decorative parts, installed on the edge of the top cover assembly. In actual use, the heat generated by the air fryer during operation will cause the structure of the top cover assembly, especially the metal decorative parts, to gradually increase in temperature, posing a risk or disadvantage of burning the user.

[0004] To address the issue of cooling the top cover assembly, cooling components are typically incorporated into it to achieve overall temperature reduction. However, due to the differences in materials and structures between the top cover assembly and the metal decorative parts, the cooling process lacks specificity and cannot effectively control the temperature rise of the metal decorative parts. The overall structure requires further improvement and optimization. Utility Model Content

The housing 300 has an air inlet 301. The housing 300 is provided with a decorative part 310. An air inlet duct 102 is provided between the air guide hood 200 and the housing 300. Part of the airflow is drawn into the air inlet duct 102 through the air inlet 301 and then flows into the cooling air cavity 101. The decorative part 310 is arranged on the cooling path of the air duct formed by the air inlet duct 102 to cool down the decorative part 310.

[0038] In this embodiment, the decorative element 310 is a metal decorative element 310, preferably a steel strip.

[0039] To facilitate the fitting and installation of the decorative part 310, that is, to fit and install the decorative part 310 on the periphery of the housing 300, and to facilitate the cooling of the decorative part 310 by part of the airflow in the air inlet duct 102, in this embodiment, the housing 300 has a slot 302, the decorative part 310 is fitted and installed in the slot 302, and part of the airflow in the air inlet duct 102 flows through the inner side of the decorative part 310.

[0040] The air guide shroud 200 is provided with an air guide rib group 210, and the air guide shroud 200 is connected to the air duct wall 220. Part of the inner wall of the housing 300 abuts against the air guide rib group 210. The air guide rib group 210, the air duct wall 220 and the housing 300 together enclose and form the air inlet duct 102.

[0041] Furthermore, part of the airflow in the air inlet duct 102 flows through the inner wall of the slot 302, and the decorative part 310 is fitted and snapped into the slot 302.

The snap-fit ​​hole 304 is connected to the air inlet pipe 102, so that when the cold air flows through the surface of the slot 302, it will cool the decorative part 310 in a targeted manner and effectively control its temperature rise.

[0043] Specifically, multiple buckles 311 are provided on the inner side of the decorative part 310 along its length. Two adjacent buckles 311 are arranged vertically relative to each other, and the corresponding snap-fit ​​holes 304 are also arranged accordingly. That is, the decorative part 310 can be fixed in both vertical and horizontal directions relative to the decorative part 310, which helps to improve the assembly stability of the decorative part 310. Through the cooperation of the buckles 311 and the snap-fit ​​holes 304, the decorative part 310 is assembled in the slot 302. The arranged snap-fit ​​holes 304 not only achieve the basic snap-fit ​​effect, but also facilitate the intake of some external cold airflow through the decorative part 310 into the air inlet duct 102, that is, further improve the cooling of the decorative part and more effectively control its temperature rise.
