9 is a cross-sectional view showing a side cross-sectional view of the ice discharge device in the ice ice mode, Figure 10 is a cross-sectional view showing a flat cross section of the ice discharge device in the ice ice mode.

First, when the ice discharge device is operated in the ice cube mode, the drive device rotates the rotary blade 143 of the transfer plate 150 and the crusher 140 at low speed in the reverse direction.

Then, the ice 108 introduced into the housing 130 through the ice inlet hole 132 falls to the lower outlet 134 without receiving centrifugal force because the transfer plate 150 rotates at a low speed.

At this time, the crusher 140 provided in the discharge port 134 is reversely rotated by the driving device, the rotating blade 143 and the fixed blade 142 of the crusher 140 for crushing the ice. Since the saw blades are formed only on the surfaces facing each other during the forward rotation, the ice 108 is not broken into pieces and passes under the discharge port 134 to discharge ice.

Next, the operation of the ice discharge device in the flake ice mode will be described.

11 is a cross-sectional view showing a side cross-sectional view of the ice discharge device in the crushed ice mode, Figure 12 is a cross-sectional view showing a flat cross-section of the ice discharge device in the icy ice mode.

When the ice discharge device is operated in the flake ice mode, the drive device rotates the rotary blade 143 of the transfer plate 150 and the crusher 140 at a low speed in the forward direction.

Then, the ice 108 introduced into the housing 130 through the ice inlet hole 132 falls to the lower outlet 134 without receiving centrifugal force because the transfer plate 150 rotates at a low speed.

At this time, since the rotary blade 143 and the fixed blade 142 of the crusher 140 disposed in the outlet 134 is rotated in the forward direction to split the ice, the ice 108 is the rotary blade 143 ) And is fixed between the fixed blade 142 is broken into pieces of ice is discharged.

Finally, the operation of the ice discharge device in the ground ice mode will be described.

13 is a cross-sectional view showing a side cross-section of the ice discharge device in the ground ice mode, Figure 14 is a cross-sectional view showing a flat cross section of the ice discharge device in the ground ice mode.

When the ice discharge device is operated in the ice ice mode, the drive device rotates the rotating blade 143 of the transfer plate 150 and the crusher 140 at high speed.

At this time, the driving direction of the drive device is determined according to the blade direction of the grind blade 145.

Then, the ice 108 introduced into the housing 130 through the ice inlet hole 132 does not fall downward due to centrifugal force because the transfer plate 150 rotates at a high speed. The ice is transported to the outer circumferential portion, and the ice 108 rotates while contacting the outer end portion of the transfer plate 150 and the inner circumferential surface of the housing 130.

However, since the grind blade 145 is provided on the inner circumferential surface of the housing 130, the ice 108 rotates while riding on the inner circumferential surface of the housing 130, whereby the ice blade 145 meets the grind blade 145. This ground, the ground ice is to be discharged to the outside through the ground ice discharge hole 136 formed on the inner peripheral surface of the housing 130.

Thus, the user can obtain not only whole and crushed ice but also ground ice.

In addition, it will be described below another embodiment of the ice discharge device of the present invention.

Prior to the description, it is revealed that the components of the present embodiment which are not described below are the same as the above-described embodiments.

16 is a view showing an ice discharge device according to another embodiment of the present invention.

First, the housing 230 is provided. The housing 230 is preferably located below the ice bank 120 similar to the above-described embodiment.

In addition, the housing 230 forms a space having an inner circumferential surface having a conical shape therein, and a discharge port 234 for discharging ice may be provided below the central portion. At this time, the inner space of the housing 230 is preferably made in the form of a conical shape that the diameter decreases toward the lower side, it is preferable to be formed longer in the up / down direction than the above-described embodiment.

Then, a driving device (not shown) is provided. The driving device (not shown) is a component that generates a rotational force, unlike the above-described embodiment, the rotational direction does not need to be switched, and it is preferable that the rotational speed is provided to enable adjustment.

Then, the transfer plate 240 is provided. The transfer plate 240 is similar to the above-described embodiment, it is preferable to be formed longer in the up / down direction in accordance with the length of the housing.

In addition, a grind blade 245 is installed on an inner circumferential surface of the housing 230. The grind blade 245 is provided with a step 250 with the inner circumferential surface in an up / down direction to the inner circumferential surface of the housing 230 so as to be perpendicular to the direction in which the ice 208 rotates similarly to the above-described embodiment. do. In addition, the ground ice discharge hole 136 (refer to FIG. 8) is formed along the grind blade so that the ground ice 208 may fall where the grind blade 245 is provided on the inner circumferential surface of the housing 230. It is desirable to be.

However, the grind blade 245 of the present embodiment is different from the grind blade 145 of the above-described embodiment, and is formed such that the step 250 with the inner circumferential surface varies depending on the up / down position of the inner circumferential surface of the housing 230. It is preferable to be.

That is, the step 250 is formed to increase as the lower side of the inner peripheral surface of the housing 230 increases, or conversely, the step 250 increases as the upper side of the inner peripheral surface is increased.

The housing 230 and the transfer plate 240 is formed longer in the up / down direction than in the above-described embodiment, the grind blade 245 is formed in the up / down direction is longer than the step 250 It is more advantageous to increase the difference of).

Another embodiment of the ice discharge device of the present invention is operated in the ice and ground ice mode.

First, the transfer plate 240 rotates at low speed or does not rotate in the ice mode. Then, since the ice 208 drawn into the housing 230 is not subjected to the centrifugal force by the transfer plate 240, the ice 208 is dropped to the lower portion and discharged into the ice state through the outlet 234.

And, in the ground ice mode, the transfer plate 240 is rotated to transfer to the outer peripheral portion by applying a centrifugal force to the ice 208 drawn into the housing 230.

However, since the centrifugal force acting on the ice 208 increases as the rotational speed of the transfer plate 240 increases, the inner circumferential surface of the housing 230 is formed in a conical shape that becomes wider toward the upper side. 208 rises upward through the inner circumferential surface of the housing 230. In addition, since the centrifugal force acting on the ice 208 is reduced when the rotational speed of the transfer plate 240 is lowered, the ice 208 is lowered down the inner circumferential surface of the housing 230.

That is, the height of the ice 208 in the housing 230 can be adjusted in the same manner as described above, wherein the step 250 formed by the grind blade 245 and the inner circumferential surface of the housing 230 is increased in height. As a result, the size of the pieces of ground ice is determined according to the position (height) of the ice in the housing 230.

Therefore, the position of the ice 208 may be adjusted by adjusting the rotational speed of the transfer plate 240, and through this, the size of the ground ice piece may be adjusted without having a separate crusher under the outlet 234. Can be.
