Hot air heating bread maker

Abstract

The invention discloses a hot air heating bread maker, which comprises a shell, a baking chamber, a heating tube, a bread barrel, a controller and an upper cover, wherein the baking chamber is formed in a hollow cavity formed on the shell; the bread barrel is arranged in the baking chamber; the upper cover is arranged at the top of the bread barrel; the controller is electrically connected with the heating tube; a heating chamber is formed outside the baking chamber; the heating tube is arranged in the heating chamber; a centrifugal drive fan is arranged on one side of the heating tube and on an output shaft of a drive motor; the controller is electrically connected with the drive motor; and the sidewall, connected with the heating chamber, of the baking chamber is provided with heating chamber air inlets and heating chamber air outlets which are communicated with one another. The heating tube in the baking chamber of the bread maker cannot be seen by a user, so that the user is ensured not to contact a heating body in the process of operating the bread barrel, the utilization safety of the bread maker is improved and a better bread baking effect can be achieved. Bread baked by the hot air heating bread maker has thin crust, and the surface of the bread is uniformly colored.

Description

technical field [0001] The invention relates to a hot-air heating bread machine, in particular to a full-automatic bread machine with a hot-air heating function using hidden heating elements, which belongs to the transformation technology of the bread machine. Background technique [0002] Bread machines have generally entered households in foreign countries and regions where pasta is the main food. Generally, bread machines can realize dough mixing, fermentation, baking, and heat preservation, and complete the whole process of bread making, such as figure 1 , 2 As shown, its structure mainly includes a transmission system 1.1, a casing 1.2, a motor 1.3, a baking chamber 1.4, a heat pipe 1.5, a power board 1.6, a bread bucket 1.7, a controller 1.8, and an upper cover 1.9. The controller controls the transmission of the motor 1.3 to stir the noodles, controls the heating tube 1.5 to heat, and bakes the bread in the bread barrel 1.7. Among them, the heat pipe 1.5 is placed i...

Problems solved by technology

The heating part is at the bottom, which is also affected by the position of the heating element, so the color of the bread surface is uneven

[0004] Chinese Patent Application No. 200820125449.0 discloses another bread machine with hidden heating elements. The only way to hide the heating elements is to install the heating elements in the baking chamber In the concave groove on the side of the oven, the heating element still surrounds the bottom of the baking chamber. Also affected by the position of the heating element, the color of the bread surface is uneven.

[0005] Chinese Patent Application No. 97245821.2 discloses another kind of hot air circulation heating type bread machine, and its heating part is a heating component formed by winding a heating wire , it does not have anti-dry function

Once the fan motor fails, the heating wire will burn out quickly
