Abstract

The present invention relates to a microwave oven having a casing for forming a cooking chamber and a microtron for providing microwaves in the cooking chamber, the top cooking portion being recessed from an upper surface of the casing to accommodate a cooking container, and the top cooking portion. It is applied to the lower surface to form a heat generating coating that generates heat by the microwave. Thereby, of course, two dishes can be simultaneously cooked in the cooking chamber and the upper surface cooking unit, and the cooking efficiency can be improved.

Description

microwave

The present invention relates to a microwave oven, and more particularly, to a microwave oven, characterized in that to form a heat generating coating on the lower surface of the top cooking portion.

Typically, a microwave oven, as shown in Figure 1, the cooking chamber for cooking food is formed in the main body 101, the door 106 for opening and closing the cooking chamber is provided in the opening of the cooking chamber. In addition, an operation panel 108 for operating the microwave oven by an external operation is provided in the right region of the door 106. The operation panel 108 is attached to the front of the operation panel 108, the membrane panel 110 having a plurality of operation buttons for receiving a signal from the outside, and the button door 112 for opening and closing the door 106 ) And a display window 114 for displaying cooking conditions and statuses.

In addition, a rear part of the operation panel 108 is provided with a component chamber (not shown) in which a plurality of components for microwave operation are installed. The component chamber has a high voltage transformer (HVT), a high voltage capacitor (HVC) and a microtron. Etc. are installed.

By such a configuration, a general microwave oven has a high voltage transformer (HVT) that generates a high voltage when the external power is supplied, and a high voltage capacitor (HVC) that charges a high voltage from the HVT and a voltage supply from the HVC. Microwaves, which are generated through a microtron that generates microwaves, are supplied into a cooking chamber of a microwave oven.

As described above, the conventional microwave oven cooks food contained in the cooking chamber by microwaves supplied from the magnetron to the cooking chamber. However, since the conventional microwave oven can be cooked only in the cooking chamber, when two foods need to be cooked, there is a hassle of cooking another food after finishing one cooking, and thus, time required to cook a plurality of foods. There are a lot of problems that the first cooked food cools.

Accordingly, an object of the present invention is to install a top cooking part that can be cooked on the upper surface of the casing of the microwave oven to cook at the same time in the cooking chamber and the top cooking part, as well as to apply a heating coating to the lower surface of the top cooking part. To provide a microwave oven that can further improve the cooking efficiency.

The object of the present invention is a microwave oven having a casing for forming a cooking chamber, a microtron for providing microwaves in the cooking chamber, and a top cooking portion recessed from an upper surface of the casing to accommodate a cooking container. And it is achieved by a microwave oven, characterized in that to form an exothermic coating for heating the lower surface of the upper surface cooking portion.

Here, the exothermic coating is preferably a mixture of ferrite and silicon.

In addition, the exothermic coating is preferably applied uniformly to the lower surface of the upper surface cooking portion.

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

2 is a perspective view of a microwave oven having a top cooking unit according to the present invention. As shown in this figure, the microwave oven is provided with a cooking chamber 2 for cooking food in the casing 1. In the cooking chamber 2, a tray 4 is provided to put food to be cooked, and a door 6 having a window in which a metal mesh is installed on the front of the cooking chamber 2 to see the inside of the cooking chamber 2 during cooking. Is installed. In the right region of the door 4, an operation panel 8 for operating the microwave oven by external operation is provided. The operation panel 8 is attached to the front of the operation panel 8, the membrane panel 10 having a plurality of operation buttons for receiving a signal from the outside, and the button door 12 for opening and closing the door 6 And a display window 14 for displaying cooking conditions and statuses. In addition, the upper surface of the casing (1), the top cooking unit 20 that can support the cooking vessel is provided to enable cooking in the cooking chamber (2) as well as cooking in the cooking chamber (2).

On the lower surface of the upper surface cooking unit 20, as shown in FIG. 3, the exothermic coating 26 is uniformly applied to make cooking in the upper surface cooking unit 20 more efficient. At the rear of the operation panel 8, a component chamber 18 in which a plurality of components for microwave operation is provided is formed. The component chamber 18 has a high voltage transformer (HVT), a high voltage capacitor (HVC) for charging a high voltage from the HVT, and a microtron for generating microwaves and supplying the microwaves according to the voltage supply from the HVC. (16) is provided.

Here, the exothermic coating material 24 is a mixture of silicon and ferrite in a ratio of about 7 to 3, and is a material that generates heat upon contact with microwaves supplied from the microtron 16. The exothermic coating 24 is a material that has undergone safety tests due to adhesion and temperature rise, and does not cause swelling or scratch bubbles even at a high temperature above a predetermined temperature. In addition, the exothermic coating 24 may cook food placed on the upper surface cooking unit 20 more efficiently since the temperature rise speed is high when microwave is supplied.

As a result, the present microwave oven can enable simultaneous cooking in the cooking chamber and the upper surface cooking unit, and the cooking efficiency of the upper surface cooking unit can be further improved by the exothermic coating uniformly coated on the lower surface of the upper surface cooking unit.

As described above, according to the present invention, the upper surface of the casing is provided with an upper cooking portion capable of cooking to enable cooking at the same time in the cooking chamber and the upper surface cooking portion, by uniformly applying a heating coating to the lower surface of the upper surface cooking portion There is provided a microwave oven which can further improve the cooking efficiency of the top cooking unit.
