BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave oven, and more particularly, to a microwave oven having an upper cooking surface that can be cooked on an upper surface of a casing of a microwave oven, and having a cooking lid on the upper surface 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 having to cook another food after finishing one cooking, and thus the 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 provide a microwave oven capable of cooking at the upper surface of the casing of the microwave oven, which enables cooking at the same time in the cooking chamber and the upper surface cooker. It is to provide a microwave oven that can improve the cooking efficiency by installing a cooking lid to cover the top surface to reduce the heat dissipation when cooking food.

The object of the present invention is a microwave oven having a casing for forming a cooking chamber and a microtron for providing microwaves in the cooking chamber, which is recessed from an upper surface of the casing and can accommodate a cooking container. It is achieved by a microwave oven comprising an upper surface cooking portion, a heating means for heating the lower surface of the upper surface cooking portion, and a cooking lid provided on the upper surface cooking portion.

Here, it is preferable to include a rack-shaped shelf between the lid and the upper surface cooking portion.

The heating means may include a heating material applied to the lower surface of the upper surface cooking unit to generate heat by microwaves of the microtron, and the heating material may be a mixture of ferrite and silicon.

Preferably, the heating material is uniformly applied to the lower surface of the upper surface cooking portion.

In addition, it is preferable that the cooking container further comprises a sensor for detecting whether it is deposited on 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. 3 is a cross-sectional view of FIG. 2. As shown in these drawings, the present 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 door button 12 for opening and closing the door 6 And a display window 14 for displaying cooking conditions and statuses. At the rear of the operation panel 8, a component chamber 18 in which a plurality of components for microwave operation is installed 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.

In addition, the upper surface of the casing (1), the top cooking portion 20 that can support the cooking vessel is provided, the cooking lid 30 for covering the top cooking portion 20 on the upper portion of the top cooking portion (20). Is installed. The upper surface of the casing 1 is formed such that one region of the sensing sensor 24 is projected.

As shown in Fig. 3, the detection sensor 24 is composed of a push bar that protrudes from the upper surface of the casing 1 and a safety contact switch operated by the operation of the push bar. In addition, a heat generating material 26 made of a mixture of silicon and ferrite is uniformly applied to the lower surface of the upper surface cooking unit 20. The heat generating material 26 is a material that has undergone safety tests that differ in adhesion and temperature rise, and does not cause swelling or bubbles even at a high temperature above a predetermined temperature.

With this configuration, the microwave oven is accommodated in the cooking chamber 2 by microwaves supplied to the cooking chamber 2 by the microtron 16 provided in the component chamber 18 formed in one region of the cooking chamber 2. Cook foods that become. Then, the upper surface cooking unit 20 starts the operation upon detecting a signal that the cooking vessel 22 is seated on the upper surface cooking unit 20 from the sensor 24. At this time, the heating material 26 is heated by the microwave to be cooked in the food container placed in the cooking vessel 22 is placed on the top cooking unit 20. In addition, the lid 30 provided on the upper portion of the upper surface cooking unit 20 reduces heat dissipation to the outside during cooking, and improves food cooking efficiency.

As a result, the present microwave oven can control the operation of the top cooking unit in a state in which the cooking vessel is not seated on the top cooking unit by a detection sensor that detects whether the cooking vessel is detached from the top cooking unit. In addition, the cooking chamber and the upper surface cooking unit may simultaneously cook two kinds of dishes. And, the cooking lid may block a predetermined heat radiated to the outside from the heat generating portion of the top cooking portion.

As described above, according to the present invention, by providing a top cooking unit on the upper surface of the casing, there is provided a microwave oven capable of cooking two dishes at the same time in the cooking chamber and the top cooking unit, the top cooking unit by the cooking lid It is provided with a microwave oven to increase the cooking efficiency by blocking the heat generated from the outside to be emitted.
