The present invention relates to a high frequency dispersion apparatus of a microwave oven, and more particularly, it is to distribute the high frequency supplied from the magnetron more uniformly so that food can be cooked effectively.

Recent microwave ovens (Micro-Wave Oven) is a trend that is developed to perform a multi-function by applying the heater (Heater) to the electric wave dispersion method using the high-frequency (Micro-Wave) generated from the magnetron, this is the type of food Depending on the way the cooking proceeds in various ways.

Generally, as shown in FIG. 1 and FIG. 2, the microwave oven has a rectangular heating chamber 2 for cooking food F inside the cabinet 1 and an interior of the heating chamber 2. The drive chamber 3 for supplying the high frequency furnace and the heater heat is separated by the inner panel 4.

In addition, a tray (5) for placing a container (D) containing the food (F) is installed on the bottom surface of the heating chamber (2), the high frequency is uniformly applied to the upper side of the heating chamber (2) A stirrer fan 6 and a heater 7 for dispersing are provided, respectively.

The drive chamber 3 is provided with a magnetron 8 and a high voltage transformer 9 for generating a high frequency, respectively, and a waveguide 10 for supplying a high frequency oscillated from the magnetron 8 into the heating chamber 2. ) Is installed, and a cooling fan 11 for cooling them or blowing air into the inside of the cooking chamber 2 is installed.

On the other hand, the front panel 12 of the microwave oven is equipped with a control panel 13 having a plurality of function selection buttons 13a and a door 14, respectively, the user's function by the operation of the function selection button 13a According to the setting, the high frequency oscillated from the magnetron 8 is supplied into the heating chamber 2 through the waveguide 10, whereby the food F can be heated and cooked.

At this time, the high frequency is to be dispersed in the food (F) by the rotation of the stirrer pan (6), it is possible to conveniently and quickly cook by operating the heater (7) according to the type of the food (F).

However, in the above-described microwave oven, as one stirrup fan 6 is disposed at the center of the heating chamber 2 to disperse high frequency foods F, the foods are rotated by the stirrer pan 6. The problem that the high frequency distributed in (F) is not constant has been caused.

That is, the high frequency supplied into the heating chamber 2 through the waveguide 10 is diffusely reflected by the rotation of the stirrer pan 6 to be dispersed in the food F, but the reflection angle of the high frequency is the rotation of the stirrer pan 6. Since it is determined according to the state, it will not be distributed uniformly in the heating chamber 2 as a whole.

Therefore, the amount of the high frequency applied to the food F is partially different, so that the portion of the food F to which the high frequency is concentrated is first cooked, which acts as a factor that delays the cooking time of the food F. FIG. In addition, the food (F) is partially burned too much, such that the nutrients are destroyed, there is a problem that the cooking state is uneven.

The present invention is proposed to solve the conventional shelf problems as described above,

As a pair of stirrer pans are rotated by air blowing, the high frequency supplied from the magnetron is more uniformly dispersed in the heating chamber, so that food is heated evenly and cooked efficiently, which reduces cooking time and improves food cooking conditions. It is an object of the present invention to provide a microwave high frequency dispersion device for improving the reliability of the product.

A feature of the present invention for achieving the above object is that, in dispersing a high frequency supplied from a magnetron in a heating chamber, a first guide plate having an inlet port through which air is supplied is formed, and the air is divided into a center line. A guide panel having a second curved guide plate having a plurality of outlets so as to be blown in a gentle curved shape; It is installed on both sides of the guide panel to be rotated freely, and one side is in the high frequency dispersion apparatus of the microwave oven consisting of a pair of stirrer pans so that the stirrer plate is assembled by the coupling pieces respectively.

Hereinafter, one preferred embodiment of a high frequency dispersion apparatus of a microwave oven according to the present invention will be described in detail with reference to the accompanying drawings.

3 is an exploded perspective view showing a high frequency dispersion apparatus of the microwave oven according to the present invention, and FIG. 4 is a cross-sectional view of the high frequency dispersion apparatus.

First, as illustrated in FIGS. 1 and 2, the microwave oven has a rectangular heating chamber 2 for cooking food F inside the cabinet 1, and the heating chamber 2. And a drive chamber 3 for supplying high frequency and heater heat therein are separated by the inner panel 4.

In addition, a magnetron 8 and a high voltage transformer 9 for generating a high frequency are respectively installed in the driving chamber 3 of the microwave oven, and a waveguide for supplying the high frequency oscillated from the magnetron 8 into the heating chamber 2. 10 is installed.

On the other hand, in the microwave oven, a convection assembly (not shown) is used to cook the food F while hot air is circulated in the heating chamber 2, and the convection assembly is a convection motor. It consists of a convection fan and a cooling fan that are rotated by a drive.

Reference numeral 20 denotes a guide panel, and the guide panel 20 is made of synthetic resin to allow high frequency to pass therethrough.

The guide panel 20 is formed in a rectangular shape and has a lower side of the inner panel 4 constituting the heating chamber 2 by a plurality of engaging pieces 21a and coupling pieces 21b formed on both sides of the body 21. Assembled in the side, the bottom surface of the body 21, two fixing projections 22 are formed at a predetermined distance apart from each other, the fixing projections 22 are formed in a conical shape.

In addition, the body 21 of the guide panel 20 is formed with a first guide plate 23 having an inlet 23a at the center of one side surface, and the first guide plate 23 is driven by the convection assembly. The air to be blown is guided to act.

Here, the inclined surface 23b inclined at a predetermined angle is formed at the end of the first guide plate 23 to guide the air to flow smoothly, and the width of the inlet 23a is gradually widened from the inclined surface 23b. It is preferably formed.

Meanwhile, a second guide plate 24 having two outlets 24a and 24b is formed at a predetermined distance from the inlet 23a side of the first guide plate 23, and the second guide plate 24 is formed. Silver is formed in a gentle curve so that the air flowing into the inlet (23a) is bisected and blown around the center line, the overall shape of the second guide plate 24 is formed to form an inequality.

Reference numeral 30 denotes a pair of stirrer fans made of synthetic resin, and the stirrer fans 30A and 30B have a conical fixing protrusion 31 having a concave recess 31a at the center thereof, and a stirrer fan 30. Silver recesses 31a are fitted to the fixing protrusions 22 of the guide panel 20 so as to rotate freely, and a plurality of ribs 32 and coupling pieces 33 are provided on one side of the stirrer fan 30. Each is formed.

The coupling pieces 33 of the stirrer fans 30A and 30B are fitted to the coupling holes 35 formed in the stirrer fan 34 to be assembled to each other. The through hole 36 is formed in the center thereof and is fitted to the fixing protrusion 31, and the stirrer plate 34 is preferably made of aluminum (Al) with high frequency reflection.

In the microwave high frequency dispersion apparatus according to the present invention as described above, when the food F is cooked by dispersing high frequency in the heating chamber 2, the air is driven by the convection assembly. It flows in through the inlet port 23a.

Here, the first guide plate 23 of the guide panel 20 guides the air to be smoothly introduced by the inclined surface (23b), the air passing through the inlet (23a) of the second guide plate 24 The guide is divided into two sides on the center line and blown.
