Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] Such as Figure 1-Figure 3 As shown, a microwave oven with hot air convection function includes a cavity body, a door body, a first heating tube on the top plate of the cavity, a cooling fan, a second heating tube on the rear panel of the cavity, and a hot air convection fan , Furnace chamber temperature detection circuit and peripheral electrical device control circuit. A furnace lamp and a ventilation hole are respectively arranged on the side panel of the cavity. The heat dissipation fan forms an air path between the top plate and the furnace cavity, which reduces the heat conduction from the top of the furnace cavity to the top plate through the air, and at the same time dissipates heat to the top plate.

[0041] Further, such as image 3 As shown, the furnace chamber temperature detection circuit includes a metal probe, a capacit...

Abstract

The invention provides a microwave oven with a hot air convection function and a control method thereof. The microwave oven comprises a chamber, a door, a first heating tube arranged on the top plate of the chamber, a cooling fan, a second heating tube and a hot air convection fan both arranged on the rear panel of the chamber, an oven chamber temperature detection circuit and a peripheral electric device control circuit. A furnace lamp and vent holes are respectively arranged on and formed in the side panel of the chamber. The control method comprises the following steps: (1) setting standard oven chamber environment temperature values at different microwave oven set temperatures; (2) enabling the microwave oven to start working and detecting the environment temperature values of the oven chamber in real time; (3) comparing the detected environment temperature of the oven chamber with the standard oven chamber environment temperature values, and controlling the working conditions of the cooling fan, the hot air convection fan, the first heating tube and the second heating tube according to the comparison result. The microwave oven with the hot air convection function is capable of keeping the desired set temperature in the oven chamber accurately for a long time and also avoiding overhigh temperature at the top of the oven chamber.

Description

technical field [0001] The invention relates to the technical field of microwave ovens, in particular to a microwave oven with hot air convection function and a control method thereof. [0002] Background technique [0003] At present, the hot air convection microwave ovens used on the market mainly use electromagnetic relays to control the work of the heating tube and the fan. One end of the electromagnetic relay is connected with a control signal, and the other end is connected with a heating pipe and a fan motor. When the heating tube and fan need to work, the upper computer sends a control signal to the control terminal to realize the conduction of the electromagnetic relay, and the heating tube and fan work. During the working process of the fan motor, the heating pipe is blown to cause the air circulation in the furnace cavity to achieve the hot air convection effect. However, the existing microwave ovens with hot air convection function have the following disadvant...
