Description

Microwave Disperser

The present invention relates to a microwave oven, and more particularly, to a microwave high frequency dispersion apparatus for distributing high frequency introduced into a waveguide to uniformly prepare food.

In general, a microwave oven is a device that cooks food by uniformly heating food using a high frequency (microwave) generated from the magnetron, it is possible to perform a variety of cooking, such as cooking food, as well as cooking the food. .

As shown in FIG. 1, in the structure of the microwave oven, a cooking chamber 11a for cooking is formed inside the main body 10 by a cabinet 11, and a magnetron 12 is formed at one side of the cabinet 11. Waveguide 13 for guiding the high frequency radiated from the () to the cooking chamber (11a) is formed.

In addition, a stub 14 is fixed inside the waveguide 13 to disperse the high frequency oscillated from the magnetron 12 so that the food F is uniformly heated, and a drive motor below the cabinet 11. The tray 17 which rotates in accordance with the drive of 16 is seated.

Therefore, when the microwave oven is operated by selecting the cooking conditions while the food is placed on the tray 17, the high frequency oscillated from the magnetron 12 is radiated to the cooking chamber 11a through the waveguide 13 and simultaneously driven. As the tray 17 rotates according to the driving of the motor 16, the high frequency is irradiated evenly on the food placed thereon, thereby cooking the food.

In addition, the high frequency wave guided by the waveguide 13 into the cooking chamber 11a is dispersed by the stub 14 fixed inside the waveguide so that the food F is uniformly irradiated and thus uniform cooking of the food is achieved. do.

However, in the conventional microwave high frequency dispersion apparatus, since the stub 14 for dispersing the high frequency generated from the magnetron 12 is fixed to the inner upper side of the waveguide 13, the stub 14 has a constant shape. There is a problem that the high frequency is dispersed evenly to the food evenly, there is a problem that the cooking of food is not uniformly made.

Therefore, the technical problem to be achieved by the present invention, that is, the object of the present invention to solve the above problems of the high frequency dispersion apparatus of the conventional microwave oven, by changing the position of the stub by the operation of the fan motor during cooking to the waveguide The present invention provides a microwave high frequency dispersion device capable of further enhancing the cooking performance of a microwave by completely dispersing the high frequency induced in the cooking chamber and irradiating food with high frequency evenly.

Microwave dispersion apparatus of the microwave oven according to the present invention for achieving the above object, the main body; A cabinet formed to have a cooking chamber inside the main body and provided with a waveguide for guiding high frequency to the cooking chamber through an opening at an end thereof; A magnetron installed in the duct to generate a high frequency; A stub installed near the opening and distributing high frequency into the cooking chamber; A microwave oven provided above the magnetron and having a fan and a fan motor for cooling the magnetron, the microwave oven being connected to the shaft of the fan motor and having a moving means for moving the stub in a lateral direction. do.

Here, the moving means is a fixing member for fixing the stub; And a guide member configured to transfer the fixed member by receiving power of the fan motor.

Therefore, in the present invention, by dispersing the high frequency induced into the waveguide by using a conventional fan motor, the food is uniformly heated and the cooking time is significantly shortened.

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

2 is an overall cross-sectional view showing a high frequency dispersion device of a microwave oven according to the present invention, and FIG. 3 is an enlarged cross-sectional view showing the main part of the present invention.

In the drawing, the cooking chamber 21b for cooking by the cabinet 21 is formed inside the main body 20, and the high frequency oscillated by the magnetron 22 is introduced into the opening 21a on the upper side and the side of the cabinet 21. The induction waveguide 23 is fixed, and the tray 25 which is rotated according to the operation of the drive motor 24 is coupled to the lower side of the cabinet 21.

A stub 35 for dispersing the high frequency wave guided by the waveguide 23 is fixed to the upper portion of the waveguide 23 by a moving means.

The moving means includes a fixing member 36 for fixing the stub 35 and a guide member 34 for transferring the fixing member 36 by receiving power from the fan motor 31.

In addition, a stub 35 for dispersing the high frequency oscillated by the magnetron 22 is fixed to the waveguide 23 so as to be movable to the guide member 34 by the fixing member 36.

A drive gear 32 is formed on the shaft of the fan motor 31 for rotating the guide member 34, and one end of the guide member 34 is engaged with the drive gear 32 to rotate. ) Is formed.

That is, the guide member 34 is rotated in gear coupling with the shaft of the fan motor 31, the fixing member 36 is geared with the guide member 34 is moved in the transverse direction.

An upper hole 23a is formed at an upper end of the waveguide 23 so that the fixing member 36 penetrates and moves in the lateral direction.

Hereinafter, the operation of the high frequency dispersion device of the microwave oven according to the present invention will be described in detail.

When the cooking conditions are selected and the microwave oven is operated while the food F is seated on the tray 25, the high frequency oscillated from the magnetron 22 is applied to the stub 35 fixed inside the waveguide 23. As a result, the high frequency is uniformly irradiated onto the food F by being dispersed and introduced into the cabinet 21.

As the tray 25 rotates according to the operation of the drive motor 24, the high frequency introduced into the cabinet 21 is uniformly irradiated onto the food, thereby preparing food.

At this time, when the fan motor 31 that cools the magnetron 22 is operated, the drive gear 32 is rotated, the rotational force is transmitted to the guide member 34 through the transmission gear 33 to guide member 34 ) Performs a rotational movement.

When the guide member 34 performs the rotation operation, the stub 35 fixed by the fixing member 36 coupled to the shaft performs the movement operation in the lateral direction, and the fan motor 31 performs the reverse rotation again. When the guide member 34 performs reverse rotation, the stub 35 fixed to the fixing member 36 moves in the opposite direction to disperse the high frequency induced into the waveguide 23 so that the high frequency is more uniform in the food F. To be investigated.

Therefore, the high frequency transmitted to the food F becomes uniform, thereby making food not only uniformly heated but also cooking quickly, thereby improving cooking performance of the product.

As described above, according to the present invention, by distributing the high frequency induced into the waveguide by using a conventional fan motor and uniformly radiating high frequency to the food placed in the cooking chamber, the food is uniformly heated and the cooking time is significantly shortened. In this way, the cooking performance of the microwave oven may be improved.
