Description

microwave

The present invention relates to a microwave oven, and more particularly, to a microwave oven having a top cooking portion that can be cooked on an upper surface of a casing of a microwave oven.

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 it is necessary to cook a plurality of foods. There is a lot of time, the problem is that the first dish is cold.

Accordingly, it is an object of the present invention to provide a microwave oven capable of simultaneously cooking in a cooking chamber and an upper surface cooking unit by providing an upper surface cooking unit capable of cooking on the upper surface of the casing of the microwave oven.

According to the present invention, in the microwave oven having a casing for forming a cooking chamber, and a microtron for providing microwaves in the cooking chamber, the upper surface cooking unit which can be provided on the upper surface of the casing to support the cooking vessel; It is achieved by a microwave oven, characterized in that it comprises a heating means for heating the lower surface of the upper surface cooking portion.

Here, it is preferable that the upper surface cooking portion is recessed from the upper surface of the casing to accommodate the cooking vessel.

In addition, the heating means is preferably attached to the lower surface of the upper surface cooking portion includes a heat generating material that generates heat by the microwave of the microtron.

Preferably, the heating material is a mixture of ferrite and silicon, and the heating material is preferably 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 with a top cooking unit according to the present invention, Figure 3 is a cross-sectional view of FIG. 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 button door 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 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). A sensing sensor 24 is installed at an adjacent position of the upper surface cooking unit 20 to detect whether the cooking vessel 22 is placed on the upper surface cooking unit 20. In addition, the lower surface of the upper surface cooking unit 20 is provided with a heating material 26 which is a heating means for heating the food contained in the cooking vessel 22 and seated on the upper surface cooking unit 20.

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. At the same time, when the microwave generated from the microtron 16 is supplied into the cooking chamber 2, the heating material 26 that generates heat by the contact of the microwaves generates heat, and the food is placed on the top cooking unit 20. This is cooked. At this time, the heating material 26 is a mixture of ferrite and silicon is uniformly applied to the lower surface of the top cooking portion 20, the heating material 26 is on the top cooking portion 20 in the sensor 24. It works after confirming that the cooking vessel 22 is seated.

As illustrated in FIG. 4, the detection sensor 24 is installed to protrude one region on the upper surface of the casing 1. The detection sensor 24 is comprised by the push bar 23 which protrudes in the upper surface of the casing 1, and the safety contact switch 25 operated by the operation of this push bar 23. As shown in FIG. The safety contact switch 25 is switched on when the cooking vessel 22 is seated on the top cooking unit 20 and the push bar 23 is pressed to supply power, and the cooking vessel 20 is not seated. In this state, no power is supplied to the off state.

As a result, the microwave oven can prevent the top cooking unit from being operated in a state in which the cooking vessel is not seated on the top cooking unit by a sensor for detecting whether the cooking vessel is detached from the top cooking unit. And, the cooking chamber and the upper surface cooking unit can be operated at the same time can be two dishes at the same time.

As described above, according to the present invention, by providing a top cooking unit on the upper surface of the casing, it is possible to cook not only in the cooking chamber but also in the top cooking unit outside the cooking chamber to provide two microwaves at the same time. do.
