Is provided. In addition, a high frequency leakage blocking device is provided to prevent high frequency leakage to the outside when the door is opened during operation.

In the conventional microwave oven, when a food is placed on a tray inside a cavity, a microwave of high frequency is generated in the magnetron. The high frequency wave is guided to the cavity through the waveguide, and is reflected from the metal wall inside the cavity, and is absorbed mainly by moisture, which is the main ingredient of the food, and is heated as a whole not only the surface of the food but also deep inside. Therefore, the cooking by microwaves has the advantage that the food itself generates heat because it is more efficient than other heating methods, the cooking time is shortened and less nutrients are destroyed.

However, since the conventional microwave oven is mainly installed in a home or a restaurant and configured to be used indoors, there is a problem that it cannot be used outdoors at all, and it must be driven using battery power outdoors, but the capacity is limited so that it can be used for a long time. There was a problem of disappearing.

The present invention was devised to solve the above-mentioned conventional defects and problems, and can be conveniently used by the user while being outdoors, and cooked by using the advantages of dielectric heating by high frequency and radiant heating by solar energy.

In order to achieve the above object, a portable microwave oven according to the present invention includes a main body provided with a cooking chamber, a high frequency generator coupled to the main body and generating a high frequency by DC power to heat food contained in the cooking chamber, and generating the high frequency. It includes a direct current power source for operating by applying power to the device, and a solar light concentrator for condensing sunlight and irradiating the interior of the cooking chamber to heat food.

The solar light collecting device is hinged to open and close a pair of opening and closing plate to the both sides of the upper opening of the main body to be opened and closed, the angle is adjustable by the opening and closing device, the inner surface of both the opening and closing plate to collect the solar light into the cooking chamber The condenser to project is fixed.

In addition, a high frequency blocking element is attached to the upper opening of the main body to prevent high frequency leakage such as a porous mesh plate.

The operation unit provided on one side of the front portion of the microwave oven main body may be provided with buttons for manipulating the opening and closing operation of the opening and closing device, and various buttons provided in the conventional microwave oven may be combined.

In addition, by the selection button provided in the operation unit, the high frequency and the solar energy can be selected to be used at the same time as a food heating source, or to cook using any one alone.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in more detail as follows.
