Embodiment Construction

[0029] Below, the microwave oven of the present invention will be described in detail with reference to the drawings and embodiments.

[0030] figure 2 Shown is the furnace lamp control circuit diagram of the present invention, furnace lamp 1, furnace lamp 2 and furnace lamp 3 are LED lamps, tungsten filament lamps or colored bulbs, which have lower energy consumption, high luminous efficiency and long service life, avoiding frequent user replacement, increasing user satisfaction. Among them, the furnace lamp 1 is a blue LED lamp, the furnace lamp 2 is a red LED lamp, and the furnace lamp 3 is a green LED lamp. The three furnace lamps can be set together or separately. They can be set on one side of the heating chamber or The top of the heating chamber.

[0031] Of course, the number of furnace lamps is not limited to 3, and changes to the number and setting positions of furnace lamps and the color of furnace lamps are all within the scope of protection of the present inven...

Abstract

The invention discloses a microwave oven lamp. The quantity of the microwave oven lamps is two or more; each oven lamp is provided with an independent control circuit; and the circuit of each oven lamp can be closed or disconnected by a single chip microcomputer according to programs or instructions. The invention also discloses a control method for the oven lamp, comprising the following steps of: 1) starting the microwave oven and receiving the control instruction by the single chip microcomputer; 2) starting a prearranged working mode and starting the corresponding oven lamp according to the prearranged program; 3) receiving the commands to start or shut down the corresponding oven lamp according to the commands by the single chip microcomputer if inputting the commands in a control panel, and if not, entering the step 4) directly; and 4) when opening the oven door, turning on a red lamp when the temperature in the chamber exceeds the prearranged temperature, and turning on a green lamp when the temperature in the chamber does not exceed the prearranged temperature. By adopting a plurality of LED (light-emitting diode) oven lamps of different colors and by combining the control on the oven lamps, the indicating of different colors in the oven chamber can be realized under different working modes; and when an oven door is opened, the alarms can be given to a user according to the temperature in the chamber, thus avoiding the occurrence of accidental scalding.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a microwave oven lamp and a control method thereof. Background technique [0002] Generally speaking, a microwave oven is a device that is powered on, uses electric energy to generate ultrashort waves through a magnetron, and irradiates ultrashort waves on food and other heated objects for cooking. The microwave oven includes a cooking cavity, a casing, and a door. [0003] The cooking cavity is used to place the food to be cooked, and its bottom can be moved so that the food can be heated evenly. Movement includes 360o rotation and left and right movement. When the food volume is large, the left and right movement is usually used. In addition, a plurality of exhaust holes are formed on the side of the cooking cavity, which can discharge the internal steam to the outside, and the internal steam is discharged to the outside through the exhaust port arranged on the shell of the microwave oven...
