The present invention relates to a rotating plate transporting device which allows the cooking plate placed on the rotating plate to be easily and safely taken out by moving the rotating plate to the door of the microwave oven after cooking.

The conventional microwave oven has a drawback that it is difficult to pull out the cooking vessel placed on the rotary plate because the rotating plate is to be rotated or stopped only at a predetermined position.

In other words, when food is cooked, the heat is transferred to the cooking vessel, and when the cooking vessel becomes a high temperature, there is a drawback that it is not easy to pull out the cooking vessel deeply placed in the narrow space of the microwave oven.

In order to solve the above-mentioned drawback, the present invention installs a lifting roller which can be lifted to the lower part of the rotating plate to move the rotating plate toward the door of the microwave oven, so that the cooking vessel is placed on the rotating plate or the cooking is completed. The purpose is to enable safe and easy handling when the cooking vessel is to be taken out in a hot state.

The present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the diaphragm 2 is formed in the microwave oven main body 1, and the shaft 5 of the rotary plate 4 is coupled to the motor shaft 3, so that a plurality of roller hools are provided on the diaphragm 2. Perforations (6), and the bottom surface of the diaphragm (2) is coupled to the movable plate (7), which is in close contact with the diaphragm (2), but the movable plate (7) is provided with a catching hose (9) having a spring (8) On both sides of the central hool (10) is perforated the roller hool (11) corresponding to the roller hool (6), the transfer plate 13 is moved to the left and right by the motor (12) in the lower part isolated from the diaphragm (2) And a lifting frame 15 movable only in the up and down direction between the guide plate 14 and the lifting plate 15, and a feeding roller 17 actuated by the motor 16 is installed in the lifting frame 15. The shaft 18 of the 17 passes through the lifting frame 15 to be coupled to the inclined guide groove 19 of the transfer plate 13, and the motor 12 is the rack gear 20 of the transfer plate 13. ) To the left and right The pin 21 protruding from the upper side of the transfer plate 13 is to be caught by the catching hole 9.

Reference numerals 22 and 23 are limit switches, and 24 are doors.

In the present invention, the circuit diagram in which the motor 16 is stopped by the switch for operating the motors 12 and 16 and the limit switches 21 and 222 is omitted because it is an axiom technology.

In the present invention, when the door 23 of the microwave oven is closed, power is cut off to the motors 12 and 16 by a cutoff switch (not shown).

When the user opens the door 24 and presses the motor 12 operation switch, the motor 12 is driven for a predetermined time to move the rack gear 20 to one side, and at the same time integrally with the rack gear 20. Since the conveying plate 13 is moved horizontally, the moving plate 7 hanging on the pin 21 is moved to coincide with the roller hole 11 of the moving plate 7 and the roller hole 6 of the diaphragm 2. do.

Thus, the movable plate 7 is moved so that the roller plate 11 is completely inserted in the state in which the roller hool 11 and the roller hose 6 coincide with each other, and the transfer plate 13 is the same. Even in the direction, the pin 21 pushes only the spring 8 to contract only the spring 8.

In this way, the conveying plate 13 continues to move, and the shaft 18 of the conveying roller 17 penetrated to the outside of the lifting frame 15 is forcibly lifted along the guide groove 19 so that the lifting frame 15 ) Is vertically raised, the feed roller 17 is projected from the lower part to the top through the roller roller 11 (6), at which time the rotary plate 4 is lifted by the feed roller 17 to move the motor shaft ( Departure from 3).

In this way, when operating the motor 16 in a state in which the rotary plate 4 is placed on the transfer roller 17, the feed roller 17 is rotated so that the rotary plate 4 is moved toward the door 24.

When the rotary plate 4 is moved toward the door 24 and touches the limit switch 23, the motor 16 is stopped.

On the contrary, when the motor 16 is rotated in reverse, the rotary plate 4 returns to its original position, and when the rotary plate 4 contacts the limit switch 22, the motor 16 is stopped.

In this state, when the motor 12 is rotated in reverse, the transfer plate 13 is horizontally moved to its original position, whereby the lifting frame 15 is lowered, followed by the pin 21 in the latching hole 9. It is moved to the opposite side of the spring (8) to move the moving plate (7), roller roller 11 is shifted from roller roller (6) is blocked roller roller (6) is blocked.

The present invention has the effect that the rotary dish 4 is moved toward the door 24 when the cooking vessel is inserted or withdrawn, and can lower or raise the cooking vessel from the rotary dish 4 safely and easily.
