Referring to the operation of the present invention constituting the above configuration based on the accompanying drawings as follows.

1 and 2 show the cooking and take-out state of the popcorn maker according to the present invention, Figure 1 is a cooking vessel 60 and the heating fan 61 is sealed by the low-speed rotation of the deceleration control motor 21 Figure 2 is a longitudinal cross-sectional view of the cooking state, Figure 2 shows the lifting shaft 30 is lowered by the high-speed rotation of the deceleration control motor 21 and the gap formed between the cooking vessel 60 and the heating fan 61. The longitudinal cross-sectional view of the state in which the food 2 is taken out is shown in preparation.

As shown in FIG. 1, when a popcorn maker according to the present invention is to be operated, power is supplied to a deceleration control motor 21 and a heating fan 61 by operating a power button of a control panel (not shown). Through the material inlet 13 above the case 10, the material 1, such as corn, is introduced.

The injected material 1 is collected at the lower end of the hopper 14, and is continuously supplied into the cooking vessel 60 by a predetermined amount by the rotation of the rotary damper 15 that opens and closes the hopper 14.

At the same time, the deceleration control motor rotates at a low speed for an initial predetermined time.

The drive shaft 20 coupled with the 21 is rotated at constant speed, and the rotational force thereof is the lifting shaft 30 supported by the fixed support shaft 50 and the heating fan 61 fixed to the lifting shaft 30. ) Is rotated at a constant speed, and the heating wire 63 of the heating fan 61 is gradually heated to heat the material 1 introduced into the cooking vessel 60.

As the heating fan 61 rotates and the fixed support shaft 50 remains stationary, the cooking vessel 60 is formed by a stirring rod 51 formed in a horizontal direction perpendicular to the fixed support shaft 50. The internal accumulated material 1 can be heated evenly while stirring, and the cooking vessel 60 is maintained by maintaining the rotational speed of the deceleration control motor 21 in an initial state for a preset time when cooking is completed. ) And the heating fan 61 to be sealed.

At this time, the heating wire 61 of the heating fan 61 is rotated in the state in which the slip ring 36 fixed to the lifting shaft 30 in contact with the contact terminal 37, the power supply through the wire 35 Supplied and continuously generate heat.

When such a state is maintained for a predetermined time and the material such as corn 1 is cooked in a popcorn state, as shown in FIG. 2, by operating a button on the control panel, the rotational force of the deceleration control motor 21 is increased. As a result, the drive shaft 20 is gradually rotated at a high speed, and as the centrifugal force gradually increases on the weight 45 of the lift shaft drive mechanism 40 by the increase of the rotational force, the lift shaft 30 is applied. And the heating fan 61 is formed by a predetermined width, that is, while lowering by the length of the guide hole 32 to form a predetermined gap between the cooking vessel 60 and the heating fan 61, thereby allowing the food 2 to be cooked through the gap. This drop is collected in the take-out guide plate 12 and can be automatically taken out into the storage container (9) through the outlet (7).

Here, the principle of the power supply of the heating wire 63 and the descending principle of the lifting shaft 30 is as follows.

When the rotational force of the deceleration control motor 21 is increased, the rotational force is transmitted to the drive shaft 20 and the lifting shaft 30, respectively fixed to the lower end of the driving arm 43 of the lifting shaft drive mechanism 40. The weight 45 of the centrifugal force is going to occur to the outside occurs.

The centrifugal force of each of the weights 45 increases as the rotational force of the drive shaft 20 and the lifting shaft 30 increases, so that the drive arm 43 has its shaft pin fixing hole 43b and a support link. Swivel shaft pin coupled between the shaft pin fixing hole (41b) of the (41)

At the center of rotation (42), the end portion of the weight weight 45 side rises to the outside, and the end of the locking groove 44 side descends together with the locking projection 34 of the lifting shaft 30. The corresponding lifting shaft 30 is lowered along the axial direction of the drive shaft 20 by turning correspondingly.

At this time, the restoring spring 46 is maintained in a relaxed state to the tension force to be restored toward the drive shaft 20 position, the engaging projection 34 in the locking groove 44 of the drive arm 43 By contact rotation, the lifting shaft 30 is lowered without friction interference, and the lowering width of the lifting shaft 30 reaches the state where the guide pin 25 of the driving shaft 20 is in contact with the upper part of the guide hole 32 of the lifting shaft 30. Limited to

As the lifting shaft 30 is lowered as described above, the heating pan 61 is also simultaneously lowered to generate a gap between the cooking vessel 60 and the heating pan 61, and the food 2 falls between the gaps. It is done.

In addition, when the lifting shaft 30 is lowered at the same time as the rotation, the slip ring 36 of the power connection portion (P) presses the bearing 31 and the lifting plate 38 at the same time as the rotation of the contact terminal 37 The power supply can be maintained continuously by simultaneously descending in a state of being in contact with the rotation.

As described above, after the one step from the input of the material 1 to the take-out of the food 2 is completed, the time required for repeating the next step is appropriately selected to automatically select the amount of the food 2 to be taken out. After the series of cooking and take-out processes are completed, the rotational force of the deceleration control motor 21 is initialized so that the lifting shaft drive mechanism 40 may restore the restoring force of the restoring spring 46 and the weight 45. By returning to its original state by its own weight, the locking projection 34 is upwardly pressed from the locking groove 44 of the driving arm 43 so that the position of the guide pin 25 in the guide hole 32 reaches the lower end. The arm 43 pushes up the lifting shaft 30.

On the other hand, even in this case, the bearing 31 and the elevating plate 38 of the power connection portion P are contacted with the slip ring 36 while being upwardly pressed by the stopper 36a formed at the center circumference of the elevating shaft 30. As the terminal 37 rises in a state of being in rotational contact, the power supply state can be continuously maintained as in the case of the lowering of the lifting shaft 30.

According to the popcorn maker according to the present invention as described above, simply by inserting the ingredients and operating the power button is heated in the cooking container for a certain period of time after the completion of cooking is completed a series of processes to take out the automatic cooking And it is possible to take out, the use and operation of the device is easy, and since the operation time of the device can be selectively controlled after the completion of one step, there is an advantage that the amount of food can be properly adjusted.

As described above, the present invention has been described for only one preferred embodiment, but it is apparent to those skilled in the art that various changes and modifications can be made within the technical spirit of the present invention based on the above embodiments. It is natural that such modifications and modifications fall within the appended claims of utility model registration.
