Description

Multifunctional microwave oven {MULTI-FUNCTION MICROWAVE OVEN}

The present invention relates to a microwave oven, and more particularly, to a multifunctional microwave oven having a roasting function.

Various kinds of apparatuses have been proposed to date as heating apparatuses for heating foods. The most basic heating device is a container that is in direct contact with the heat source, the contents to be cooked in such a container can be cooked by applying heat to heat.

In addition, many types of cooking apparatuses that use electric energy directly or indirectly have been developed. As an example, a microwave oven using microwaves as a heating source may be mentioned. A microwave oven is a cooking apparatus that generates microwaves using electricity to infiltrate a cooking object and heats the cooking object by causing molecular motion therein.

A common microwave oven is a kitchen appliance that heats the inside and outside of the microwave by irradiating the high frequency of the magnetron to the food at the same time, significantly reducing the cooking time of the food due to high thermal efficiency, and losing the nutritional value during cooking, thawing and warming of the food. It is also widely used because of the advantages such as cooking directly while the food is stored in the container.

In addition, recently, there is a single-function microwave oven that cooks food using a microwave of 2450 MHz, which is only fired from a magnetron. In addition to microwaves, a grill heater is provided above or below the cooking chamber to serve as a grill. There is a multifunctional microwave oven, such as a microwave oven having a grill, or a microwave oven having a convection heater and a convection fan at the rear of the cooking chamber in addition to the microwave and having an oven function to convection hot air.

1 is a view schematically showing a multifunctional microwave oven equipped with a conventional grill heater.

As shown, the cooking chamber 11 for cooking food is formed in the case 10 having a front surface opened.

The open portion of the cooking chamber 11 is opened and closed by the door 15.

On the other hand, a separate grill 13 is provided for cooking food with the grill heater 12, the grill 13 is stored separately in the usual, and inserted into the cooking chamber 11 as needed.

According to the conventional multifunctional microwave oven, when only one grill heater is provided in the upper or lower portion of the cooking chamber, when cooking food using the grill heater (hereinafter referred to as 'cooking cooking'), one side of the upper or lower portion of the food Since the bay is heated, in order to cook the food evenly, there is an inconvenience in that the food placed on the grill should be turned upside down from time to time.

In order to alleviate this inconvenience, when the grill heater is provided at the top and the bottom at the same time, the manufacturing cost increases and a large amount of power is consumed.

In addition, according to the conventional multi-function microwave oven, there is a limitation in the size of the grill, the amount of food that can be cooked when cooking the grill, there is a problem that can not efficiently cook a large amount of food at the same time. Therefore, there is a need for improvement.

The present invention was devised to improve the problems of the prior art as described above, when cooking the grill, there is no inconvenience to turn the food from time to time, not only can efficiently cook a large amount of food at the same time, The object is to provide a multifunctional microwave oven with an improved structure to minimize the increase in manufacturing costs and power consumption.
