Rotary air flow generator and kitchenware

The present invention relates to a kitchenware, more precisely, to a kitchenware that can produce a dazzling flame cyclone effect during cooking, and a rotary airflow generator built in the kitchenware, which is both practical and ornamental.

In an environment full of catering industry, in addition to the color and flavor of food, the added value of dining interior decoration or dining atmosphere can also attract a lot of points. On the other hand, in order to draw closer to chefs and consumers The distance between people, many restaurant operators began to design transparent kitchens to show the process of food cooking. However, in the past, the improved kitchen utensils had no other characteristics than meeting the needs of cooking food.

Based on the above purpose, the present invention provides a rotary airflow generator, which includes a flame output device and an axial-flow impeller. The impeller has a base and at least one blade extending outward from the edge of the base, which can be driven by the driving device to generate a rotating gas flow field flowing toward the flame output device. The flame output device is coaxially disposed with the impeller, and the flame mouth is rotated by the rotating gas flow field. surround. Thereby, the flame generated by the flame mouth is pulled by the rotating gas flow field, and a flame vortex burning upwards of the air outlet is generated.

Further, an air chamber can be provided to stabilize the rotating gas flow field generated by the impeller. In detail, the air chamber may have an inner wall and an outer wall provided outside the inner wall, defining an inner contour and an outer contour of the rotating gas flow field.

Further, the flame output device is provided with a fuel passage that communicates with the flame mouth, so that the flame continues to burn.

Further, the base of the axial-flow impeller may be a ring-shaped base, and a plurality of blades are provided on the inner edge of the base, and a plurality of teeth are provided on the outer edge of the base, so that the driving device is correspondingly disposed on the outer side of the impeller, so Make the most of the space under the base.

In addition, the present invention also provides a kitchenware. The cookware is arranged between the flame output device and the impeller, and the flame mouth of the flame output device passes through the potware and is surrounded by the rotating gas flow field.

Further, in addition to setting the air chamber to stabilize the rotating gas flow field, the outer contour of the cooker can also be used as the inner contour of the rotating gas flow field, which simplifies the assembly of components.

Further, the pot can be a soup pot, which is defined by the outer wall of the pot and the inner wall of the pot that penetrates and extends from the bottom of the pot to the opening direction, so that the center of the pot can be set through the flame output device. In addition, the flame output device may be provided with a plurality of flame ports, in addition to generating special-effect flames on the side of the air outlet higher than the opening of the pot, other flame ports may provide a heat source for cooking food toward the surface of the pot.
