Microwave oven for baking food

Abstract

The invention relates to a microwave oven capable of baking food directly by using the microwave energy, belonging to a microwave oven. The microwave oven comprises a microwave generator, a transformer, a cooling fan, a high-voltage capacitor, a control circuit board, a microwave generating and controlling device, an oven body, a cylindrical operating cavity, vent holes, a waterproof / oilproof wave-penetrating partition plate, an electromotor, a rotary disc, a grill with a central shaft, and a semi-cylindrical surface shaped oven door body, wherein a control panel is arranged in the microwave generating and controlling device, the cylindrical operating cavity is arranged in the oven body, the vent holes are arranged on the oven body, the waterproof / oilproof wave-penetrating partition plateis arranged between the microwave generating and controlling device and the operating cavity, the electromotor is arranged at the bottom of the operating cavity, the rotary disc can rotate unidirectionally with the electromotor, the grill is arranged on the rotary disc, and the semi-cylindrical surface shaped oven door body is provided with a microwave shielding case. The microwave oven provided by the invention can carry out baking on the food directly by using the microwave energy, and the required time for baking potatoes, livestock, poultry, and aquatic product foods is only about 50% of that consumed by using the background technology; and by using the microwave oven provided by the invention, the food can be baked uniformly and better in taste, the food baking speed and the baking efficiency are effectively improved, and the energy source is saved, therefore, the microwave oven is especially suitable to be used for baking mass food by barbecue restaurants, and the like.

Description

Technical field [0001] The invention belongs to a microwave oven, in particular to a microwave oven that directly uses microwave energy to cook food. Background technique [0002] In the field of microwave heating technology, microwave ovens are widely used to quickly heat food. A microwave oven is a household appliance that uses electromagnetic energy in the microwave frequency band to heat food and beverages in the cavity. This type of microwave oven includes a microwave oven body and a microwave working cavity (resonant cavity) set in the oven body, a oven door, and a microwave generator, Microwave generation and control devices including transformers, cooling fans, capacitors, control circuits (boards) and their control panels; the principle of heating food is to convert electrical energy into microwave energy through microwave generators (including magnetrons and waveguides) After the food is transmitted to the working cavity, a distributed microwave field is established in...

AI Technical Summary

Problems solved by technology

This heating method has the characteristics of fast heating speed and easy control of heating time for heating soup foods, milk and other beverages, foods without hard shells, and heating cold dishes and cold rice; but it cannot be directly used for baking food , especially roasted livestock, poultry, and aquatic foods

[0003] The ordinary household microwave oven with barbecue function has a barbecue function to heat food through the quartz tubes arranged inside the cavity. Although the use of quartz tubes can bake food, it has slow speed, high energy consumption and low efficiency. and other defects

The patented technology disclosed in the patent document with the announcement number CN201032198 and the title "Microwave Oven with Barbecue Function" belongs to this type of microwave oven. Although the patent uses three heating devices to increase the heating speed, so many heating tubes make the microwave oven have high energy consumption and high efficiency when baking food. Low, due to the limitation of the heating method, the speed of baking food is still slower than that of direct microwave energy, and it cannot be used for baking large batches of food such as barbecue restaurants.
