When the electrical components installed in the electronic room are operated by the user's operation, the microwaves are supplied to the inside of the heating chamber to start the heating of the food. When food is heated by the wave, the moisture contained in the food easily evaporates, and thus the food dries.

On the other hand, most foods can feel the taste of the food when it contains an appropriate amount of water, and in this way, a significant amount of water in the food during the heating of food using microwave in the microwave oven It has been a significant obstacle to its dissemination and use.

Recently, as part of an attempt to solve the problem that the moisture contained in the food is lost during the heating of the food in such a microwave oven, by spraying water directly into the heating chamber, the method of humidifying the inside of the heating chamber by ultrasonic waves. Or a method of storing water in the heating chamber was used, but there were problems of hygiene, low humidification efficiency, and complexity of the structure for implementing such a function.

The present invention is to solve the above problems, an object of the present invention is that the moisture contained in the food is not lost during the heating of food by microwave, hygienic, simple structure capable of high-efficiency humidification into the heating chamber It is to provide a microwave.

In order to achieve the above object of the present invention,

According to an aspect of the present invention, the heating chamber includes a main body and a humidifying means for supplying moisture into the heating chamber, wherein the humidifying means comprises a porous ceramic structure and a water reservoir for supplying water to the porous ceramic structure. A microwave is provided.

In addition, the microwave oven according to an aspect of the present invention further includes a support plate disposed on the bottom surface of the heating chamber, wherein the porous ceramic structure is disposed under the support plate, and at least a part of the porous ceramic structure. It is preferred that the zone is submerged in a water reservoir.

In this case, the support plate is preferably formed of heat-reinforced glass.

As described above, the microwave oven according to the present invention does not lose moisture contained in the food during the heating of the food by the microwave, it is hygienic and simple structure, it is possible to high-efficiency humidification into the heating chamber.

Hereinafter, a microwave oven according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings show exemplary forms of the present invention, which are provided to explain the present invention in more detail, and the technical scope of the present invention is not limited thereto.

The microwave oven 1 according to an embodiment of the present invention is an electric device for heating a heating object (for example, food or the like) using microwaves.

As shown in FIG. 1, specifically, inside the main body 2 forming the basic frame of the microwave oven 1, a heating chamber in which microwaves are supplied and a heating object F (eg, food) is accommodated is provided. In the adjacent side of a heating chamber, the electrical chamber with which the electrical component for generating a microwave is mounted is formed.

The heating chamber may be configured to be opened and closed by a door to a space for heating the food by microwaves supplied by the electric chamber while the food F to be heated is accommodated therein.

On the other hand, when food is heated by microwaves in an enclosed space inside the heating chamber of the microwave oven 1, the moisture contained in the food easily evaporates, and therefore, to prevent the food from drying out, one of the present invention The microwave oven 1 according to the embodiment includes humidifying means for supplying moisture into the heating chamber.

Here, the humidifying means includes a porous ceramic structure (20, 200) and the water reservoir (30, 300) for supplying water to the porous ceramic structure (20).

In this case, the porous ceramic structures 20 and 200 are media capable of supplying a large amount of moisture into the heating chamber of the main body, and have a large surface area for vaporization and capillary function for excellent high temperature durability and humidification.

If the porous ceramic structures 20 and 200 can supply moisture in the heating chamber, the porous ceramic structures 20 and 200 may be disposed at any position of the main body 2. However, in one embodiment, the porous ceramic structures 20 and 200 may be disposed below the bottom surface of the heating chamber. The case where the porous ceramic structures 20 and 200 are disposed is illustrated.

The porous ceramic structures 20 and 200 may be formed by joining or laminating one or more selected from the group consisting of honeycomb, ceramic plate paper, and ceramic corrugated paper so that the contact area with air in the heating chamber increases. It may have various shapes such as a rectangle, a donut shape, and the like. The porous ceramic structures 20 and 200 may contain a large amount of moisture therein due to high porosity and capillary pressure.

On the other hand, the porous ceramic structure (20, 200) constituting the microwave oven 1 according to an embodiment of the present invention may be disposed so that a portion of the region is submerged in the water reservoir (30, 300), and thus the porous ceramic structure ( 20, 200) contains a large amount of water therein due to the high porosity and capillary pressure.

That is, since the porous ceramic structures 20 and 200 have a large contact area with air due to the micropores and honeycomb shapes, the porous ceramic structures 20 and 200 may contain a large amount of moisture therein.

Meanwhile, the porous ceramic structures 20 and 200 may further include an antimicrobial coating layer. If moisture absorption and evaporation are performed for a long time, water moss or various foreign matters may be deposited on the porous ceramic structures 20 and 200, and silver nano or titanium dioxide may be used to prevent harmful foreign matters emitted from the outside. It is also possible to coat photocatalysts such as TiO2).

The porous ceramic structures 20 and 200 are very porous due to their microstructures, and thus have a large specific surface area, which has an advantageous supporting property for immediately applying antimicrobial coating.
