The present invention relates to a method of driving a tray of a microwave oven, and more particularly, by varying the position of the tray according to the type of the cooking object so that cooking can be performed at the most suitable tray position. The present invention relates to a tray driving method of a microwave oven.

As shown in FIG. 3, the conventional microwave oven is provided with a driving motor 50 generating a driving force by applying power to the lower portion of the side plate 55, and a coupler 59 at an upper end of the driving motor 50. The tray 54 is connected by means of), and rollers 58 are provided on the lower surface of the tray 54 to help smooth rotation of the tray.

The microwave oven configured as described above places a cooking object on the tray 54 and then drives and drives the driving motor 50 to rotate the tray 54 connected to the motor shaft via the coupler 59.

At this time, the tray 54 is smoothly rotated by the roller 58.

In this way, when the tray 54 is rotated, the cooking object seated on the tray 54 is cooked by electromagnetic waves by a normal microwave function.

Since the tray of the conventional microwave oven always rotates at a constant height regardless of the type of the cooking object, there is a problem in that cooking of the cooking object heated by the electromagnetic waves generated from the magnetron is not heated evenly and is unsatisfactory.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, the present invention is fixed in accordance with the operation of the corresponding key of the cooking object to the height of the tray input to the height input to the operation panel and in this state An object of the present invention is to provide a tray driving method of a microwave oven which can be cooked in an optimal state at an optimal position of a cooking object ratio by oscillating.

Hereinafter, the technical configuration for achieving the object of the present invention with reference to the accompanying drawings in detail.

1 is a view illustrating an embodiment of an apparatus implemented by an embodiment of the present invention, which executes a key input unit 10 consisting of various corresponding cooking objects corresponding keys and a system operation program, and compares the data with the data set according to the input data. And a tray driving control unit 30 for controlling the operation of the tray driving means 100 described below by the microcomputer 20 for transmitting the control signal and the output control signal of the microcomputer 20. The configuration of the tray driving means 100 is a forward and reverse drive motor 40 for generating a forward or reverse rotational driving force by applying power and a drive force of the forward and reverse drive motor 40 is transmitted through the belt 41 to reverse the forward and reverse directions. The drive gear 42 and the drive gear 42, which are freely rotated, are engaged with each other around the drive gear 42 in a structure that satisfies the condition of being raised during forward rotation and falling during reverse rotation. A plurality of lifting gears 43 combined with the lifting gears 43 are attached to the upper portion of the lifting gears 43 so as to support the tray 44, and the lifting gears smoothly through the transfer holes 46 of the side plates 45. It is composed of a support member 47 to be accompanied up and down and a roller 48 seated on the support member 47 upper surface to facilitate the smooth rotation of the tray 44. In addition, a drive motor 49 for rotation is connected to the center of the lower surface of the tray 44 via the coupler 50.

The operation of the device to be implemented by the method according to the present invention configured as described above is the forward and reverse drive motor (when the user selects the cooking object corresponding key of the key input unit 10 while the cooking object is seated on the upper surface of the tray 44) As the power is applied to 40), the forward and reverse drive motor 40 is driven in the forward or reverse direction.

The driving force is transmitted to the drive gear 42 through the belt 41 to drive the drive gear 42, and the plurality of wins coupled to the periphery of the drive gear 42 so as to continuously move up and down in accordance with the rotational direction of the drive gear. The falling gear 43 is to move up or down.

At this time, the support member 47 coupled to the upper portion of the elevating gear 43 is driven up and down through the transfer hole 46 of the side plate 45, and in this process, the roller 48 is attached to the support member 47. The tray 44 in a supported state is changed up and down by a predetermined height to have a position suitable for cooking of a cooking object.

On the other hand, the tray 50 is rotated by the drive motor 49.

FIG. 2 is a flow chart according to the present invention, which detects whether the tray 44 is the most suitable position for the cooking object through the step STl of detecting whether the corresponding key of the cooking object is selected (ST2) It is not set to the most suitable position for the object (N) by rotating the forward and reverse drive motor 40 to adjust the position of the tray 44 through the tray driving means 100 to the most suitable height for the cooking object and to a suitable position If it is set (Y) while performing the cooking operation performing step (ST4) while performing the step (ST3) to stop the forward and backward drive motor 40, while detecting the remaining cooking time during the cooking operation (ST5) (N) If the cooking operation is continuously performed and the cooking remaining time is not left (Y), the cooking process is terminated (ST6), and the reverse driving motor 40 is reversed (ST7). 44) to the original position It allows to execute the action that was.

Then, when the tray 44 is detected to return to its original position (ST8), if it is not returned (N), the tray return operation by the reverse rotation of the forward and reverse drive motor is continued, and when it is returned (Y), the forward and backward drive motor is stopped. This is configured as an operation procedure of the step ST9.

Referring to the effect of the present invention configured in this way in more detail as follows.

When the cooking object to be cooked is placed on the upper surface of the tray 44 of the microwave oven, and the corresponding object of the cooking object of the key input unit 10 is selected, the microcomputer 20 detects whether the cooking object corresponding key is selected (STl). Detects whether the position of the tray 44 is most suitable for the object to be cooked, i.e., detects the position of the tray 44 (ST2), and if it is not set to the proper position (N) through the tray driving controller 30. The forward and reverse driving motor 40 of the tray driving means 100 is rotated forward so that the forward rotational driving force is sequentially transmitted to the belt 41, the driving gear 42, the lifting gear 43, and the supporting member 47. The tray 44 is adjusted to the position most suitable for cooking of the object to be cooked, and if it is set to the most suitable position (Y), the stationary drive motor 40 is stopped (ST3), and the electric equipment such as the magnetron is operated. Cooking action type of microwave (ST4) And advances.

Then, it detects whether the remaining cooking time remains (ST5) and if it remains (N), it continues to perform the cooking operation, and if the remaining cooking time does not remain (Y), the operation of the electric equipment for microwave cooking is stopped to cook. End (ST6).

Then, when the cooking is completed as described above, the forward and reverse driving motor 40 is rotated in reverse (ST7), and the driving force is sequentially transmitted to the belt 4, the driving gear 42, the lifting gear 43, and the supporting member 47. As a result, the raised tray 44 is returned to its original position.

At this time, if it is detected that the position of the tray 44 is returned to its original position (ST8) and if it is not returned (N), the forward / reverse drive motor 40 continues to be rotated in reverse to proceed with the original position return operation of the tray 44. If the tray 44 is returned to its original position (Y), the reverse rotation drive of the forward and reverse drive motor 40 is stopped (ST9).

As described above, in the method according to the present invention, since the tray of the microwave oven is changed to a position previously input by the corresponding key operation of the cooking object, the cooking of the cooking object is advanced at the most suitable position, so that the optimum cooking state is achieved. It can be maintained.

Claims (1)
