Abstract
The invention discloses a drum microwave oven, comprising a casing, an oven chamber, an oven door and a magnetron, a waveguide, a motor and a control circuit. A turntable, arranged at the bottom of the oven chamber, is driven by the motor to rotate in the manner of speed change and direction change. The microwave generated by the magnetron is radiated into the oven chamber through the waveguide. The turntable arranged at the bottom of the oven chamber is fixed with a cylindrical container for receiving food, and the glass-type cylindrical container is fixed on the turntable by a clamper. The glass container performs left-right rotation and speed change rotation under the driving of the motor, therefore, evener heating by microwave radiation is available to the food inside the glass container.
Description
Technical field
The present invention relates to micro-wave oven, particularly relate to the micro-wave oven of the cartridge type glass container that has rotating placement food.
Background technology
Micro-wave oven is the household electrical appliance that utilize high-frequency microwave that food is heated and cooks, and carries out operation by the frictional heat that food molecule high vibration under the radiation effects of high-frequency microwave produces.During the cooking in microwave oven operation, microwave penetration food, can inside and outside heating simultaneously, it is fast and use plurality of advantages easily to have an efficient height, speed.Therefore, micro-wave oven progressively becomes widely used domestic electric appliance.
The outward appearance of micro-wave oven is rectangular shape, and there is fire door in the housing front of cuboid, fire door one side setting operation key.Form furnace chamber in the housing, the cavity of furnace chamber is the metal material of microwave reflection.The side of furnace chamber is provided with the internals of micro-wave oven, mainly comprises magnetron, waveguide, control circuit device and agitator etc.
Magnetron is the heart of micro-wave oven, is a kind of vacuum device, is used to produce the continuous microwave of heat food.The microwave that magnetron produces is carried and is radiated on the food in the furnace chamber by the waveguide of high-conductive metal material.Agitator is made with the metal such as the magnadure plate that conduct electricity very well, intensity is high, just as screw, drive by small machine, in rotatablely moving, constantly change reflection angle to the microwave radiation, thereby improve the distribution of microwave field in the furnace chamber, the food in the furnace chamber is heated evenly.Generally speaking, micro-wave oven is not provided with agitator, and the rotating disk of support food is set in the furnace chamber bottom, makes every effort to be subjected to the food that rotating disk rotatablely moves the even heating of microwave radiation.
Fire door is the passage of placing food and take out food in the furnace chamber in furnace chamber, has enough mechanical strengths, and that long-term switch uses is still indeformable, non-cracking and microwave leakage do not occur.The observation window of fiberglass is equipped with in fire door central authorities, accompanies intensive pore metallic shield net in the fiberglass, can see cooking status in the stove during use, can make the unlikely leakage of microwave again.
The control circuit device is arranged in the housing; comprise control circuit and respective electric parts thereof; mainly contain power controller, high-tension transformer, high-voltage capacitor, overheat protector, timer, interlocking switch and interlocking pilot switch, rotary tray motor (or agitator motor), fan electromotor etc., its function guarantee and control the normal operation of whole micro-wave oven.
Fig. 1 is general microwave oven structure schematic diagram.During the applied microwave stove, open the fire door 3 in micro-wave oven casing 1 front, food is put on the rolling disc 5 in the furnace chamber 2, close upper furnace door 3, push key 7, control circuit board conducting, the operation of each electric component, the microwave that magnetron 8 produces awards food radiation heating in the furnace chamber 2 by waveguide 6.Simultaneously, the rotating disk 5 of furnace chamber 2 bottoms rotates under driven by motor, is placed on the even heating that also is subjected to the microwave radiation on the rotating disk 5 in company with the food that rotates.After food heating and the cooking are finished, open fire door again, take out food.
But the micro-wave oven of above-mentioned prior art, the food of heating are put on the interior rotating disk of furnace chamber, exist food to heat uneven problem.
Summary of the invention
Micro-wave oven at prior art exists food to heat uneven problem, the present invention releases drum microwave oven, by the cylindrical container of containing food is set on the furnace chamber rotating disk, and rotating disk can speed change and commutation rotation, makes the food in the cylindrical container accept more uniform carry out microwave radiation heating.
Drum microwave oven of the present invention, the cylindrical container of containing food that is provided with on the furnace chamber rotating disk is a glass container, is fixed on the rotating disk by the Fastener that is provided with on the rotating disk.The rotating disk that is connected with motor shaft rotates under driven by motor, and rotating disk can speed change rotate, and direction of rotation can change.
During micro-wave oven work, furnace chamber is injected in the microwave radiation, and the food in the furnace chamber rotating disk upper glass container is subjected to carry out microwave radiation heating.Simultaneously, glass container is with rotating disk left rotation and right rotation and speed change rotation under the drive of motor, and the food in the glass container obtains more even heating.

The specific embodiment
Now in conjunction with the accompanying drawings to being described further for the present invention.
Fig. 2 shows drum microwave oven furnace cavity structure of the present invention, and Fig. 3 shows that glass container among Fig. 2 is fixed on the situation on the rotating disk.
As shown in Figures 2 and 3, there is fire door in housing 1 front of the cuboid of micro-wave oven, fire door one side setting operation key 7.Form furnace chamber 2 in the housing, the cavity of furnace chamber 2 is the metal material of microwave reflection.The side of furnace chamber 2 is provided with the internals of micro-wave oven, mainly comprises magnetron, waveguide, control circuit device etc.
Magnetron turns round by the control circuit device that is provided with in the housing 2, produces the microwave of continuous heat food.The continuous microwave that magnetron produces is carried and is radiated on the food in the furnace chamber by the waveguide of high-conductive metal material.
Fire door is the passage of placing food and take out food in the furnace chamber in furnace chamber, and the observation window of fiberglass is equipped with in fire door central authorities, accompanies intensive pore metallic shield net in the fiberglass, can see cooking status in the stove during use, can make the unlikely leakage of microwave again.
The bottom of furnace chamber 2 is provided with support rotating disk 5, is fixed with the tubular glass container 10 of containing food on the rotating disk 5, and glass container 10 is fixing by the Fastener 11 that is provided with on the rotating disk 5.The bottom of rotating disk 5 is connected with motor shaft 12, and rotating disk 5 rotates under driven by motor.Motor can speed change and the break-in rotation, and glass container 10 is with rotating disk 5 left rotation and right rotation and speed change rotation under the drive of motor.
When micro-wave oven is used, from the fire door in micro-wave oven casing 1 front, the tubular glass container 10 that fills food is placed on the rotating disk 5 and fixing by Fastener 11.By operated key 7 turn-on control circuit plates, the microwave that magnetron produces is by waveguide radiation in furnace chamber 2.Simultaneously, the rotating disk 5 of furnace chamber 2 bottoms rotates under driven by motor, is fixed on glass container 10 on the rotating disk 5 with rotating disk 5 left rotation and right rotation and speed change rotation under the drive of motor, and the foods in the glass container 10 obtain more even carry out microwave radiation heating.
