2 is a cross-sectional view of a portable microwave oven according to the present invention.
3 is a sectional view of a portable microwave oven having another structure according to the present invention.
4 is a cross-sectional view of a transparent cooking container used in a portable microwave oven according to the present invention.

Hereinafter, the present invention will be described more specifically with reference to the drawings.

2 is a sectional view of a portable microwave oven designed in the present invention. The portable microwave oven has an outer lid 5, a lower main body 6, a cooking chamber 7, a heating unit 10, an operation and control unit 11, A shielding plate 12, a vibration device 13, and the like. A pressure regulator 14 is attached to the outer lid 5 and a gasket 15 is provided between the outer lid 5 and the lower main body 6 to prevent steam or liquid from leaking out. The heating section is composed of a magnetron 8 for generating a microwave and a waveguide 9 serving as a passage through which the microwave moves.

The operation and control unit 11 can be installed anywhere in the outer lid 5 or the lower main body 6. The operation and control unit 11 is provided with a button for selecting a cooking method according to the type of food, It is desirable to install a program including various measures for cooking and safety such as heating intensity, heating cycle, heating intensity control with elapse of cooking time, and automatic stop function during short circuit or overheating.

The outer lid (5) is provided with an automatic locking function to prevent the lid from being opened during operation.

During operation of the portable microwave oven, the vibrating device (13) operates to vibrate the cooking vessel so that the food in the cooking vessel can be uniformly stirred, wherein the vibration is continuous continuously during operation, or alternatively between 3 seconds and 2 minutes , And can be performed periodically for 3 seconds to 2 minutes at each timing.

The vibrating device 13 may be installed at one or more places on the outer side or the lower side of the cooking chamber and further uses a resilient material or device so that the vibrating device can make strong contact with the cooking container, To protrude slightly from the wall of the cooking chamber.

The microwave generated from the magnetron 8 flows along the waveguide 9 and is irradiated to the bottom of the cooking vessel to thereby heat the food in the cooking vessel. At this time, the waveguide may be provided with an antenna for generating a circularly polarized wave.

The waveguide 9 may be installed at the lower end of the cooking chamber as shown in FIG. 2. However, in order to uniformly heat the food, a waveguide may be installed at one or more positions along the cooking chamber wall as shown in FIG. 3, More than one can be installed at regular intervals.
