Abstract

The present invention relates to a heater driving apparatus of a microwave oven, in particular, a drive motor is fixed to the inside of the cooking chamber upper and upper and lower shafts are arranged in the vertical direction in the upper and lower ends, and both ends are fixed to the lower rotary shaft and rotated by a drive motor A heater and a stir pan connected to an upper rotating shaft so as to be rotated by the drive motor, and a stir pan for distributing high frequency into the cooking chamber through a dispersion groove formed on the upper wall of the cooking chamber. The pan is rotated so that the cooker can cook the food to prevent the heater heat from concentrated heating or deviation heating in one place of the food so that the cooker can cook the food uniformly.

Description

Microwave heater driving device

The present invention relates to a heater driving apparatus of a microwave oven, and more particularly, to a heater driving apparatus of a microwave oven, by forming a microwave heater of the strut type rotatably, so that the food can be heated uniformly during cooking.

Conventionally, a microwave oven that heats food using a heater has a cooking compartment in which the food is located on one side, and a front and rear opening / closing door is provided on the front side of the cooking chamber, and an operation part for operating the microwave is formed on the other side. It is. Such a microwave oven is divided into a turntable method and a strut method according to a method of heating food.

In the turntable method, as shown in FIG. 1, the heater 2 is fixed to the upper sidewall of the cooking chamber 1, and a tray 3 that is rotated by a tray motor is formed on the bottom surface. When the driving force is generated in the tray motor, the tray 3 rotates to cook the food, and thus the food is cooked relatively uniformly even when the heater 2 is fixed.

However, since the heater 5 is fixed to the upper sidewall of the cooking chamber 4 and the food is fixed on the bottom surface of the cooking chamber as shown in FIG. 2, the heater 5 is heated only at one place of the cooking food. This intensive heating.

This is because the concentrated heating is burned and the portion that is not heated is not cooked because the deviation heating is not cooked as a whole, the problem is that the overall reliability of the product is greatly reduced.

Therefore, the present invention has been devised to fundamentally solve the problems of the prior art, and its purpose is to allow the heater to rotate, thereby preventing the concentrated heating and deviation heating generated during cooking so that the food can be heated uniformly. Furthermore, it is to provide a microwave heater driving device that can increase the reliability of the product.

The present invention as a means for achieving the above object is a drive motor is fixed to the inside of the top of the cooking chamber and the upper and lower rotary shafts are arranged in the vertical direction, and both ends are fixed to the lower rotary shaft and the heater is rotated by the drive motor And, it is characterized in that the basic configuration in the technical configuration that is configured to be connected to the upper rotary shaft so as to be rotated by the drive motor is configured to disperse high frequency into the cooking chamber through the distribution groove formed on the upper wall of the cooking chamber.

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

(Example)

3 is a front view showing a state in which a drive motor according to the present invention is installed in a microwave oven.

The present invention is a drive motor 10, the stir pan 30 and the heater 20 rotated by the drive motor 10 so that the food can be uniformly heated in the microwave oven of the strut method as shown in FIG. ) Is mobilized.

The drive motor 10 is fixed to the inside of the upper end of the cooking chamber 40, the upper rotary shaft 12 is formed at the upper end and the lower rotary shaft 11 is arranged in the vertical direction.

Both ends of the heater 20 are fixed to the lower rotating shaft 11 and rotated by the driving motor 10, and the strut fan 30 is connected to the upper rotating shaft 12 so as to rotate together with the heater 20. The cooking chamber 40 is configured to disperse high frequency into the cooking chamber through the dispersion groove 41 formed in the upper wall surface.

In order to use the present invention configured as described above, after placing the food in the cooking chamber 40 and applying power to the driving motor 10, the driving motor 10 is driven and the upper and lower rotary shafts 11 and 12 rotate at the same time. do. In this case, the heater 20 connected to the lower rotary shaft 12 rotates and heats the food evenly, and the strut pan 30 connected to the upper rotary shaft 12 rotates and rotates the high frequency through the distribution groove 41. Will be distributed into

As described above, according to the present invention, since the heater and the stir pan rotate and cook the food in the cooking chamber by the driving force of the driving motor in which the driving motor is installed on the upper side of the cooking chamber, the heater heat is concentrated in one place as in the prior art. It is possible to prevent the heating or the deviation from being heated to uniformly cook the whole, thereby increasing the reliability of the product.

The present invention has been described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and should be made by those skilled in the art to which the present invention pertains without departing from the gist of the present invention. Various changes and modifications can be made.
