Description

Soaking toaster

Technical Field

The utility model relates to the technical field of kitchen appliances, further relate to a soaking toaster.

Background

Toaster is also known as toaster, a common kitchen appliance. A toaster is equivalent to a small oven, sliced bread is placed inside, the two sides of the bread are baked through heating of the electric heating wire, and after the baking is finished, the bread is lifted upwards so as to be taken out.

The mica-based electric heating plate which is common in the market has two structures, one structure adopts an electric heating wire to wind a mica plate to form the heating plate, the other structure adopts the mica plate to press a metal foil to form the heating plate, and the common electric heating wire is made of nickel-chromium and iron-chromium-aluminum. When the bread is electrified, current passes through the electric heating wire or the metal foil to heat the electric heating wire or the metal foil, so that the bread slices are baked.

Because the electric conductivity of the electric heating wire or the metal foil is too high, a longer electric heating wire must be wound, or the metal foil is etched into a longer conductive path to increase the resistance of the electric heating wire, and the electric heating wire has larger interval and generates heat to form linear radiation, which affects the uniformity of the heat generation and further affects the taste of bread baking. In order to approach the planar heating effect, the distance between the wound heating wires or the distance between the metal foil paths can be reduced, but the risk of short circuit is increased, and the potential safety hazard is increased.

For those skilled in the art, how to improve the uniformity of bread baking is a technical problem to be solved at present.
