Multifunctional oven

Abstract

The invention discloses a multifunctional oven, which comprises an external heat-preservation oven body, a heat-preservation oven door which seals an opening of the external oven body, a metallic internal oven body the opening of which is continuously connected with the external oven body, a heat storage device which is arranged at the lower side of the internal oven body, a burning device which is arranged on the external oven body below the internal oven body, a food holding device which is arranged in the internal oven body, a flue which is arranged between the internal oven body and the external oven body and surrounds five surfaces of the internal oven body except the opening side, and an heat-preservation box, the external oven body comprises a chimney connection port, a box body and a box cover of the heat-preservation box comprise a heat-preservation layer, and side walls of an opening region of the connection of the box body of the heat-preservation box and the external oven body are internal metal side walls which form side walls of the flue. By adopting the heat storage device in the internal oven body and the heat-preservation box on the external oven body, the heat energy can be absorbed and stored, thus enhancing the heat efficiency of the oven and saving the energy, the heat-preservation box utilizes the heat of flue gas to preserve the heat of the food and store the food, thus meeting the needs of food heat preservation; and the baked food is stored in the internal oven body, the heat of the food in the oven is preserved by the heat in the heat storage device, and fuel is not needed any more, thus saving the energy and being convenient for food heat preservation.

Description

technical field [0001] The invention relates to an oven, in particular to a multifunctional oven. Background technique [0002] The oven is a cooking tool that uses heat to bake food, such as an electric oven that uses electric energy for heating, a gas oven that uses burning gas or liquefied gas for heating, and a liquefied gas oven. Baking food in an oven has the advantages of simplicity, convenience, and unique flavor. Therefore be widely used. [0003] Existing multifunctional ovens usually adopt the following structure: an inner box is arranged in an outer box with a thermal insulation structure, and the flue surrounding the five sides of the inner box except the door is between the inner box and the outer box. The box body includes a stove set under the inner box body, and a connection port with the chimney is set on the outer box body. Further heating is carried out to improve the thermal efficiency of the oven, and the flue gas is discharged from the chimney throug...

AI Technical Summary

Problems solved by technology

[0005] 1. The inner box of the oven is usually made of thin steel plate. Although it can realize the rapid transfer of combustion heat and flue gas heat, the heat storage capacity of the inner box is limited, and the combustion heat and flue gas heat cannot be fully utilized, resulting in the failure of the oven. Low thermal efficiency, resulting in energy waste;

[0006] 2. After the food is baked, it is not convenient to keep the food warm. If the fuel combustion is stopped after the food is baked, the temperature of the inner box will drop quickly, making it difficult to keep the food warm. If the fuel is continued to keep the food warm, it will bring increased fuel consumption;

[0007] 3. The function of the oven is single, and it is not convenient to keep the baked food warm while baking the food
