The present invention relates to ice dispensing, and more particularly, to a ice dispensing and taking-out device for ice dispensing which reduces the manufacturing cost by providing a motor capable of simultaneous ice picking and blowing and constantly controlling the amount of ice taken out by adding an ice counter .

1, the conventional ice dispensing includes a freezing chamber main body 1, a door body 2 which is detachably attached to the freezing chamber main body 1, And a microcomputer 3 for controlling dispensing.

The freezer compartment main body 1 is provided with an ice cube receptacle 4 at its upper portion and an ice-making motor 5 is extended and formed at one side of the ice cube receptacle 4, A take-out screw 6 is provided, and a take-out motor 7 is extended and formed on one side of the take-out screw 6. A take-out barrel 8 is attached to the lower portion of the take-out screw 6 and formed on one side thereof, that is, on the opposite side of the take-out motor 7, with a take-

The door body 2 is provided with a takeout space portion 9 at the lower portion thereof and a selector button 9a in the form of a lever is provided above the takeout space portion 9, The end portion of the take-out oil tool 8a is exposed and formed.

(C), (E), (F) and (I) which are not shown in the drawing are the take-out cup and the evaporator, the circulating fan, and ice.

Hereinafter, the operation of the conventional ice dispensing system will be described.

When water is supplied to the ice vessel 4, cold air is concentratedly supplied to the ice vessel by the evaporator E and the circulation fan F so that the water of the ice vessel 4 changes into an image I do. The ice I thus phase-changed is removed from the ice tray 4 which is twisted by the operation of the ice-making motor 5 and falls into the blow-out screw 6. When the user presses the select button 9a to consume the ice, the microcomputer 3 determines that the take-out motor 6 is operated so that the take-out screw 6 rotates and the ice I is taken out from the take- So as to drop naturally into the cup (C) of the takeout space portion (9).

However, such conventional ice dispensing has a problem in that the manufacturing cost is increased because the ice-making motor 5 and the take-out motor 7 must be provided separately in order to take out the ice I which has been dispensed.

Another problem is that the number of revolutions of the blow-out screw 6 connected to the take-out motor 7 and the number of take-out of ice particles are not exactly matched and the ice is irregularly taken out every time the select button 9a is pressed .

The present invention has been made in view of the above problems, and it is an object of the present invention to provide an ice dispensing apparatus for ice dispensing that can reduce the manufacturing cost by not having a separate motor for taking out the ice cubes.

Another object of the present invention is to provide an ice dispensing and taking-out apparatus which can always take out a predetermined number of ice every time the selection button is pressed.

In order to accomplish the object of the present invention, there is provided an ice dispensing apparatus including an ice-making device for releasing ice cubes and a blowing device for blowing the ice cubes out of the freezing compartment, And a power transmitting means for changing and delivering the power of the motor serving as both of the unloading and unloading motors for separating and performing the unloading and unloading operations and the motors of the unloading and unloading motors to the unloading and unloading devices. An unloading and unloading device is provided.

The power transmitting means is provided with a drive shaft of the motor for both the unloading and the unloading so as to be able to move forward and backward, a gear serving as both of the unloading and unloading gears is formed at the end of the driving shaft, And a slave shaft is formed on one side of the freezing motor and the take-out motor so as to be selectively engaged with each other.

The power transmission means includes a drive gear having a magnetic field that can be converted to a drive shaft end portion of the motor for both of the unloading and unloading motors and is fixed to a driven shaft end portion of the ice bowl and the driven screw so as to selectively engage with the drive gear And a driven gear having a magnetic field is formed.

And an ice counter capable of automatically rotating is attached to the inlet of the ice extraction inducing port of the takeout device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an ice dispensing and picking-up apparatus for ice dispensing according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the freezing compartment includes a take-out screw 12 mounted on the lower part of the ice vessel 11, a storage corner 13 provided below the take-out screw 12, 11b and 11d are provided with a freezing gear 11a and a takeout gear 12a at one side of the take-out gear 11 and at one side of the take-out screw 12, respectively. And a motor 14 is installed on the rear wall side of the freezing chamber.

The motor 14 for unloading and unloading is provided with a drive shaft 14b having a free end and a take-out gear 14a formed at its ends so as to be movable forward and backward with respect to the motor shaft support plate 15.

In addition, an elastic spring (not shown) is built in the take-out oil tool 16 formed at one side of the storage corner 13 so as to take out a predetermined number of ice, An ice counter 17 is mounted.

(1), (2), (3), (18), (C), (E) and (F) denote the freezing compartment main body, the door, the microcomputer, the select button, the ice receiver cup, the evaporator, and the circulating fan.

Hereinafter, the operation of the icing and dispensing apparatus of the ice dispenser according to the present invention will be described.

3, when ice is ice-cooked in the ice vessel 11, the ice-making gear 11a is engaged with the ice-making and taking-out gear 14a so that the ice-making vessel 11 is twisted The ice is dropped to the blow-out screw 12 and the storage corner 13. At this time, when the user presses the select button 18, the unidirectional gear 14a moves along the motor shaft support plate 15 while being rotated in the reverse direction, and is retracted away from the idler gear 11a, 12a to rotate the screw 12. As the blow-out screw 12 rotates, the ice is discharged to the outside through the ice pick-up oil tool 16. Here, an appropriate amount of ice is taken out by the ice counter 17 and the blow-out screw 12 ) And the operation time are controlled so that only a predetermined amount of ice particles is always taken out. The microcomputer 3 determines the respective states of the motor 14 and the ice counter 17 so that the direction of rotation of the motor 14 and the direction of rotation of the ice counter 17 Thereby controlling opening and closing.

Other embodiments according to the present invention are as follows.

The driving gear 14a of the forward and reverse rotating motor 14 is moved forward and backward and the driving gear 14a is engaged with the freezing gear 11a engaged with the driving gear 14a, Gears 12a are formed on the front and rear sides of the driving gear 14a so that the driving gear 14a selectively transmits the power while the forward and reverse rotations are performed. In this embodiment, as shown in FIG. 4 Similarly, the driving gear 14a 'having a convertible magnetic field is formed at the end of the drive shaft of the unidirectional motor 14, and the ice bowl 11a' is formed so as to selectively engage with the drive gear 14a ' (12a ') having a fixed magnetic field is formed at each of the follower shaft ends of the take-out screw 12' and the follower gear 12a 'having the same electrode as the idle and take-out motor 14a' And a gear (an idler gear 11a 'in the figure) is engaged and rotated. At this time, when the user presses the select button (not shown) again, the electrode of the driving gear 14a 'is converted and is rotated by engaging with another driven gear (the drawing gear 12a' in the figure) It will be done.

As described above, the ice dispensing according to the present invention is characterized in that the icing dispenser according to the present invention is characterized in that the icing and picking-out motor for selectively changing the forward and reverse rotations to separate and perform the ice- And the gears for separating and delivering to the respective driven gears formed on the take-out screw, thereby reducing the manufacturing cost, and an electron-sensitive ice counter is provided at the entrance of the ice- So that a predetermined number of ice can be always taken out.
