Cooking device internal hot air convection system using cross-flow fan

Abstract

The invention relates to a cooking device internal hot air convection system using a cross-flow fan, which comprises a cooking cavity, a roasting tube arranged inside the cooking cavity, and a door for opening / closing the cooking cavity. A louver for spatially partitioning the roasting tube and the cooking cavity is also arranged inside the cooking cavity, a cross-flow fan parallel to the surface of the door is arranged on the inner side of the upper part of the cooking cavity, the louver is arranged at the top and the rear part of the cooking cavity and is positioned inside the space formed by the louver and the upper and the rear walls of the cooking cavity, an air inlet and an air outlet for air ventilation are formed on the surface of the louver, and the roasting tube is arranged between the air outlet and the cross-flow fan. According to the invention, the cross-flow fan replaces the centrifugal fan in the prior art, so that the hot air in the air cooking cabinet circularly flows; and the air outlet and an air return can guide the direction of the hot air, resulting in uniform flow of the hot air, good heat conduction effect and uniform heating of food.

Description

technical field [0001] The invention relates to an oven. In particular, it relates to a hot air convection system in a cooking device which makes use of a cross-flow fan to ensure good heat conduction effect in a grill cavity of an oven and uniform grill food. Background technique [0002] The oven is a device that uses electric current to make the grill tube generate heat and irradiates the heat on the food to heat or grill the food. It can quickly heat or grill the surface of the food. Such as bread, pizza, and desserts such as egg tarts and biscuits. Meats can also be grilled. [0003] In order to allow the oven to cook food in a variety of cooking methods, the output power needs to be adjusted according to the requirements of the user. [0004] Such as figure 1 As shown, the conventional art oven has a cuboid shape, and its top surface and appearances on the left and right sides are formed by a casing 10 . [0005] A barbecue cavity 20 is formed inside the shell 10,...

AI Technical Summary

Problems solved by technology

[0010] At present, the grilling chamber 20 of the oven basically uses a centrifugal fan to guide the air. Since the grilling tubes arranged in the grilling chamber 20 of the oven are all around the periphery of the centrifugal fan, four sides of the air are formed in the grilling chamber 20. As a result of no wind in the middle, the air conduction is uneven, which affects the heating and grilling of food
