Microwave and steam cooking two-purpose microwave oven

Abstract

The invention belongs to a microwave and steam cooking two-purpose microwave oven, which comprises a barrel-type furnace body with an opened upper part and a sealed bottom, and a cylindrical working cavity arranged in the barrel-type furnace body, a spherical oven door provided with a microwave shielding layer, a microwave generation and control box, a steam heating steamer and a microwave and steam mixed heating steamer, wherein the microwave generation and control box comprises a microwave generator, a transformer, a cooling fan, a capacitor, a control circuit and a control panel. The oven body and the microwave working cavity are respectively changed into the barrel-type furnace body with the opened upper part and the sealed bottom and the cylindrical working cavity, and the lower partof the working cavity can be used for filling steam water and can also used for placing foods for cooking by directly utilizing microwaves, therefore, the microwave and steam cooking two-purpose microwave oven has the characteristics that the structure is simple and reliable, foods can be cooked by directly microwaves or steam or microwaves and steam, thus the advantage of microwave heating is fully developed, the use range of the microwave oven is effectively enlarged, and the utilization rate and the energy-saving effect of the microwave oven are improved.

Description

technical field [0001] The invention belongs to a microwave oven for food cooking, in particular to a microwave oven that can directly heat (cook) food through microwave energy, and steam cook food through steam generated by microwave heating water, and can also mix microwave and steam (commonly ) heating food is cooked microwave, steam cooking dual-purpose microwave oven. Background technique [0002] In the technical field of microwave heating, microwave ovens are widely used to rapidly heat food. A microwave oven is a household cooker that uses electromagnetic energy in the microwave frequency band to heat food and beverages in the cavity. The principle of heating food is to convert electric energy into microwave energy through a magnetron and then transmit it to the cavity, so that a distributed atmosphere is formed in the cavity. Microwave field, when the food is in the microwave field, the food will absorb microwave energy to heat the inside and outside of the food at...

AI Technical Summary

Problems solved by technology

However, the microwave oven needs to add an additional high-power steam generating device, and the generation of its steam is realized by electric heating rather than by microwave energy heating; Microwave heating or steam heating can be carried out independently, and microwave and steam heating cannot be carried out at the same time; The size of the middle water tank is limited by the volume of the microwave oven, and its water volume is limited (only 100-200ml). In addition, after the steam enters the microwave working chamber, because the working chamber has a large space and the inner wall is mostly metal, this will lead to a sharp drop in steam temperature and condensation. , and the condensed water cannot be recovered; therefore, the "Microwave with Steam Heating" exists or uses microwave heating or steam heating, and cannot be used for microwave and steam heating at the same time, nor can it be used for heating that requires a long time or a large The cooking of food with high-temperature steam, such as steamed buns, rice, steamed meat, etc., has a narrow range of use and a low utilization rate.
