Description

Baking oven

Technical Field

The utility model belongs to the kitchen appliance field relates to a household electrical appliances product, specifically provides an oven.

Background

A currently used oven is a device that cooks food in a cavity using heat from a heat source. Ovens may be largely classified into a radiant oven that cooks food using radiant heat from a heat source and a convection oven that cooks food using a fan to circulate heated air.

CN97246080.2 relates to an electric oven, which comprises a containing tank, an electric heating tube and an air net, wherein the electric heating tube and the air net are arranged above and below the containing tank, a vortex device is arranged outside the air net, the vortex device comprises a blowing cover, an air suction fan and a power device, the air net is provided with a plurality of air outlets, and the front of the power device is provided with the air suction fan.

CN200780051170.0 discloses an oven comprising a wall forming a cavity for cooking food and a convection assembly; a convection assembly is disposed exterior to the tank wall. Here, the case wall includes a convection cover recessed toward the cavity to define a heating chamber, and at least a portion of the convection assembly is located within the heating chamber.

The convection oven heating chamber is provided with a heater and a fan, and a motor for rotating the fan. When the fan is rotated, the gas in the chamber flows into the heating chamber, is heated by the heater in the heating chamber, and is resupplied to the chamber.

The existing oven mainly adopts convection type hot air conduction, and a fan is arranged on an electric heating pipe part, so that hot air generated by an electric heating pipe is blown into the oven by the fan, the hot air in the oven is convected, and the baking efficiency is improved. However, the convection effect generated by directly blowing the hot air generated by the electrothermal tube into the oven by the fan cannot make the temperature in the oven uniform, because the temperature of the windward side of the baked objects close to the electrothermal tube is far higher than the temperature of the back side of the electrothermal tube, the surface of the baked objects after being taken out of the oven is obviously different in degree of well done. In addition, most of the existing ovens are provided with one-way motors to drive fan blades to blow air into the inner cavity, so that the effect of convection hot air is achieved; and only one-way air flow can not quickly improve food coloring and lock food moisture, resulting in poor baking effect.

In view of this, the present invention is proposed.
