Description

Steam supply device for oven

This creation relates to a component of an oven, in particular to a revealer of the innovative structure of an oven’s steam supply device.

The oven used for baking food mainly uses an electric heat generator to generate heat energy to bake or heat the food or food. The heat generated by the electric heat generator does not easily penetrate into the inner layer of the food, so that when the food is fully cooked, the surface of the food It is often too dry and hard due to excessive water loss.

A conventional steam generator installed in an oven includes an electric heat generator, a heat storage body and a sprinkler pipe, wherein the heat storage body is arranged between the electric heat generator and the sprinkler, and the heat storage system is a metal plate.

The heat energy generated by the electric heat generator is absorbed by the first side, and the heat energy passes through the heat storage body to the second side. Side transfer, heat energy is transferred through the second side to the water contacting the second side, the electric heat generator heats the water indirectly through the heat storage body, and when the temperature rise of the heat storage body is insufficient, the water cannot be effectively heated up quickly. Water vapor, and the heating area of the heat storage body for water is only the surface area of the second side, it is not easy to quickly generate a large amount of water vapor in a short time, and multiple heat transfer processes also make the overall heating efficiency need to be improved.

Therefore, in view of the above-mentioned problems of the conventional steam generator installed in the oven, how to develop an innovative structure with more ideal and practicality is what users expect, and it is also the goal that the relevant industry must work hard to develop and break through.
