The present invention relates to a microwave oven, and more particularly, to a microwave oven capable of maintaining the moisture of food to be cooked at an appropriate level.

In general, a microwave oven is a device for cooking food by using a high frequency, and a device for cooking food by frictional heat between water molecules by causing the water molecules contained in the food at high frequency to translate.

However, since the microwave oven uses a frictional heat to heat the food by translating the water molecules contained in the food at a high frequency generated by the magnetron, the moisture contained in the food is evaporated and lost during the cooking process. Therefore, there is a problem that the food is dried to reduce the taste of the food.

The present invention is to solve such a problem, it is an object of the present invention to provide a microwave oven that allows to maintain the moisture of food when cooking.

Microwave oven according to the present invention for achieving this object, the tray forming the appearance and the inside of the cooking chamber is provided, the rotation motor receives the rotational force from the drive motor for generating a rotational force to rotate the food in the cooking chamber to cook And a supporting device including a plurality of rollers rotatably supporting the tray and a water holding portion opened upwardly to contain water, and a guide tray having an upper end supporting the lower surface of the tray. .

The roller is rotatably installed on the guide tray, characterized in that arranged to form a predetermined interval in the circumferential direction.

In addition, the tray is characterized in that a plurality of steam discharge holes are formed so that the steam generated in the guide tray can be supplied to the food is placed on the upper side.

In addition, the guide tray is rotated by receiving a rotational force from the drive motor through a rotation shaft, the first power transmission unit and the second power transmission formed to have a concave-convex corresponding to each other so that the rotational force can be transmitted to the guide tray and the rotation shaft. Each of the parts is provided.

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

As shown in FIGS. 1 and 2, the microwave oven according to the present invention has a main body 10 formed so as to partition the cooking chamber 11 in which food is cooked therein and the electric compartment 12 in which various electric appliances are installed. Equipped.

The cooking chamber 11 is provided with a tray 20 for rotating the food on the upper side to rotate the food evenly. The electric chamber 12 has a magnetron 12a for generating high frequency radiation to the cooking chamber 11 and a magnetron ( A high voltage transformer 12b for applying a high voltage to 12a) and a cooling fan 12c for cooling various components of the electric chamber 12 are mounted.

On the front side of the electric compartment 12, a control panel 13 in which a plurality of operation buttons 13a and the like are arranged is provided to operate various functions of the microwave oven, and the front side of the cooking chamber 11 is hinged to one side of the main body 10. The door 14 which rotates and opens and closes the cooking chamber 11 is installed.

In addition, the main motor 10 is provided with a drive motor 15 for generating a rotational force for rotating the tray 20 by applying power to the lower side of the cooking chamber 11, the bottom of the tray 20 and the cooking chamber 11 As shown in FIG. 3, a support device 30 is provided between the surfaces to allow the tray 20 to be rotatably installed in the cooking chamber 11.

At this time, the support device 30 in the microwave oven according to the present invention is to allow the tray 20 is rotatably installed in the cooking chamber 11 and at the same time to supply water to the food on the tray 20 For this purpose, the support device 30 is opened upward and the guide tray 31 is provided with a water receiving portion 31a for containing water, and the guide tray 31 is rotatably installed on the bottom surface of the cooking chamber 11. It is provided with a plurality of rollers 32 rotatably installed on the outside of the guide tray 31 so as to be spaced apart from each other in the circumferential direction. At this time, at least three rollers 32 are provided to prevent the guide tray 31 from being inclined by the weight of the food placed on the tray 20, and the roller 32 is provided at the bottom plate of the cooking chamber 11. The guide groove 11a is provided in a concave manner so that the rotary shaft rotates in a constant trajectory.

Accordingly, the tray 20 is mounted on the upper end of the guide tray 31 rotatably installed in the cooking chamber 11 by a plurality of rollers 32, and is rotatably installed in the cooking chamber 11 through the guide tray 31. Will be.

In addition, in this embodiment, the rotational force of the driving motor 15 is transmitted to the guide tray 31 so that the tray 20 is rotated indirectly by receiving the rotational force through the guide tray 31. The first power transmission part 31b is formed to have corresponding unevenness at the center side of the lower surface of the lower surface 31 and the upper end of the rotation shaft 16 so that the rotational force generated from the driving motor 15 is transmitted to the guide tray 31. And a second power transmission unit 16a are provided.

On the other hand, the tray 20 is made of glass, ceramic, heat-resistant resin, etc. so that the high frequency penetrates to reach the water contained in the water accommodating portion 31a, and the steam generated in the water accommodating portion 31a is brought to the food side. In order to be easily supplied, a plurality of vapor discharge holes 21 are formed.

In this embodiment, the first power transmission unit 31b is provided on the lower surface of the guide tray 31 so that the rotational force is transmitted to the guide tray 31 so that the tray 20 is rotated by the guide tray 20. It is also possible to provide the first power transmission unit 31b on the lower surface of the tray 20 without being provided.

Next will be described in detail the operation and effect of the microwave oven according to the present invention configured as described above.

When power is applied, high frequency is generated in the magnetron 12a and radiated into the cooking chamber 11. The food placed on the tray 20 by the radiated high frequency is heated and cooked. The tray 20 on which the food is placed is placed on the support device 30 that is rotated by the driving motor 15, so the food is cooked in the cooking chamber 11. Rotate inside and cook evenly. At this time, the moisture contained in the food is evaporated to escape to the outside of the food, the moisture contained in the food is reduced.

As described above, a part of the high frequency radiation radiated into the cooking chamber 11 during the heating and cooking of food passes through the tray 20 to reach the water receiving portion of the guide tray 31, and thus the water in the water receiving portion 31a. The vapor is discharged to the food side through the steam discharge hole 21 in the form of steam to supply water to the food.

Therefore, the food is continuously supplied with moisture by the steam generated in the water receiving portion 31a of the support device 30 in the process of heating and cooking.

As described in detail above, the microwave oven according to the present invention is provided with a water receiving portion containing water in the support device provided in the lower tray, so that water is evaporated from the water receiving portion during cooking of food to supply water to food, so that food is at an appropriate level. It has the effect of maintaining the moisture of the.
