Airflow surrounding structure for barbecue type microwave oven

Abstract

The invention provides an airflow surrounding structure for a barbecue type microwave oven. The airflow surrounding structure comprises a microwave oven cooking chamber, a pair of barbecue tubes which are arranged outside the rear side wall of the cooking chamber with ventilation holes, and a cross-flow fan arranged between the pair of the barbecue tubes, wherein air deflection structures are respectively arranged on corresponding positions of the lower part inside the rear side wall of the cooking chamber and two ends of a lower vent port; each air deflection structure comprises a base which is fixedly connected to the lower vent port inside the rear side wall of the cooking chamber; the base is of a hollow structure, an opening is formed in the middle of the base, and an air deflection tube is embedded on the opening of the base; and the air deflection structure also can be air deflection ports respectively formed on two sides of the lower vent port inside the rear side wall of the cooking chamber, and a plurality of air deflection vanes are arranged in the air deflection port vertically. The airflow surrounding structure has a simple structure, and ensures that three airflows surrounding and heating foods in different directions are formed in the cooking chamber, so that the quality of cooking foods is improved, and the cooking time is reduced; and the main airflow is prevented from rushing at the oven door, so that the damage of a high temperature to the oven door is reduced, the adverse effect of the microwave oven is reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to a grill type microwave oven. In particular, it relates to a grill-type microwave oven with a microwave oven cooking cavity, a pair of grill tubes arranged outside the rear side wall of the cooking cavity with ventilation holes, and a cross-flow fan arranged between the pair of grill tubes. structure. Background technique [0002] Generally speaking, a microwave oven is a machine that cooks food conveniently by turning on the power supply and using the microwave effect generated. In particular, recently, heating sources such as heaters have been installed in addition to magnetrons, and various cooking methods have emerged, that is, cooking methods that circulate the heat generated in the heaters, or cooking by controlling the position of the heaters. method etc. [0003] Such as figure 1 As shown, the existing microwave oven with barbecue is generally composed of the following components: a furnace body, which embraces the o...

AI Technical Summary

Problems solved by technology

[0009] 1. The high-temperature gas is easy to blow directly to the door through the gap between the food and the upper and lower walls of the cavity, causing the temperature of the door to be too high and destroying the glue strips in contact with the door and the surrounding

[0010] 2. The air outlet area is small and scattered, and the convective heating effect on food is not obvious

However, this structure does not completely solve the above-mentioned problems
