Below, the details of this ice feedway is described.

Fig. 4 is the sectional view of the structure of expression ice feedway 200.Particularly, Fig. 4 is the sectional view that schematically shows the cross section of second 121 A portion shown in Figure 3.In addition, for the ease of explanation, in Fig. 4, omit the 4th 122 and illustrate.

As shown in Figure 4, ice feedway 200 is devices of supplying with the ice that generates, has supply pipe 210, cap unit 220, bar (lever) 240 and discharge portion 250.

Supply pipe 210 is the pipes that are formed for the ice that is generated by the ice machine (not shown) that is disposed at the top is supplied to user's feed path.Supply pipe 210 has supply port 210a.

Supply port 210a is the opening of supply pipe 210.Particularly, supply port 210a is the outlet that is used to supply with the ice of ice.In addition, supply port 210a is so long as the shape that the ice of supplying with can pass through can be an arbitrary shape.

Cap unit 220 is the lids with the supply port 210a sealing of supply pipe 210.Cap unit 220 has axis body 221 and lid 222.

Axis body 221 is disposed at the top of lid 222, is the bar-shaped axle that is used to make lid 222 rotations.Particularly, axis body 221, through the rotation of axis body 221, making lid 222 is that rotate around axis body 221 at the center with axis body 221.In addition, preferred axis body 221 is disposed at the top of lid 222, but is not limited to the top, also can be disposed at central portion.

Lid 222 is to rotate through axis body 221, rotates around axis body 221, carries out the position on the flat board of switching of supply port 210a.That is, lid 222 is opened supply port 210a through the rotation (in Fig. 4, turning right) of axis body 221.In addition, lid 222 is closed supply port 210a through the rotation (in Fig. 4, turning left) of axis body 221.In addition, lid 222 is so long as the shape that can supply port 210a be closed can be an arbitrary shape.

Bar 240 is to be used to make axis body 221 to rotate, so that lid 222 opens and closes the switch that supply port 210a uses.Particularly, when the user will supply with ice in cup P, cup P is inserted into reception space 123, uses cup P to directions X pressing lever 240.In this case, owing to the bottom of bar 240 is pushed to directions X, so bar 240 is that middle mind-set directions X rotates with the upper end.And, if bar 240 turns to the angle of regulation, lid 222 is opened supply port 210a.

In addition, be fed among glass P at ice, the user takes out under the situation of cup P from receiving space 123, and bar 240 is got back to original position.And when bar 240 was got back to original position, through the position relieving rod 240 from the angle of afore mentioned rules, lid 222 was closed supply port 210a.

Discharge portion 250 is positions that the ice raft of supplying with from supply port 210a is gone out.Should be fed into from the ice that discharge portion 250 discharges user's the cup P.

Fig. 5 is the stereogram of the structure of expression ice feedway 200.In addition,, in Fig. 5, supply pipe 210, the cover (clover) 300 that covers cap unit 220 etc. are drawn as transparent, dot for the ease of explanation.

Fig. 6 is a stereogram of seeing ice feedway 200 from the rear.Particularly, Fig. 6 is a stereogram of seeing the ice feedway 200 shown in Fig. 5 from the upper right side.In addition, for the ease of explanation, in Fig. 6, omit supply pipe 210 and illustrate.

Shown in these figure, ice feedway 200 also has drive division 260.

Drive division 260 is the driving mechanisms that are used to make axis body 221 rotations.That is, drive division 260 rotates through making axis body 221, and lid 222 is rotated around axis body 221, and supply port 210a is opened and closed lid 222.

Particularly, drive division 260 drives, and makes that lid 222 is just opened supply port 210a as long as bar 240 turns to the angle of regulation.In addition, drive division 260 drives, and makes that lid 222 is just closed supply port 210a as long as bar 240 quilts are removed from the position of the angle of afore mentioned rules.

In addition, drive division 260 is fixing with axis body 221, makes that under the situation of the rotation that stops axis body 221, axis body 221 does not rotate.Particularly, drive division 260 has the gear motor by formations such as worm gears (worm gear).Therefore, if drive division 260 stops the rotation of axis body 221, then the rotation of axis body 221 is fixed on the position of drive division 260 when stopping, and the position of lid 222 also is fixed.

Fig. 7 is the functional block diagram that expression is used to control the functional structure of drive division 260.

As shown in Figure 7, refrigerator 100 also has the control part 270 that is used to control drive division 260.

Control part 270 is the handling parts that are used to control drive division 260.That is, control part 270 drives drive division 260, makes that lid 222 opens and closes supply port 210a through the rotation of bar 240.

Particularly, control part 270 control drive divisions 260 rotate axis body 221, so that lid 222 is opened supply port 210a.In addition, control part 270 rotates axis body 221, so that lid 222 is closed supply port 210a.

In addition, control part 270 control drive divisions 260 rotate axis body 221, make lid 222 close supply port 210a at interval with official hour.At this, official hour can be that a few minutes also can be several hours, does not do special qualification, but the time of the ice that preferably accompanies between lid 222 and supply port 210a dissolving.

Then, the structure to cap unit 220 at length describes.

Fig. 8 is the stereogram of the outward appearance of expression cap unit 220.

Fig. 9 A and Fig. 9 B are the vertical views of the structure of expression cap unit 220.

Shown in these figure, cap unit 220 also has force application part 223 and retainer (stopper) 224 except that axis body 221 with the lid 222.

The application of force (paying gesture) parts 223 are to connect axis body 221 and lid 222, give the position that lid 222 is closed the application of force of closing direction of supply port 210a.That is, an end of force application part 223 is fixed in axis body 221, and the other end of force application part 223 is fixed in lid 222 via retainer 224.Particularly, force application part 223 is torque springs.

Retainer 224 is fixed in the other end and the axis body 221 of force application part 223, is around position that the rotation of axis body 221 limits to the lid 222 of force application part 223 application of forces.Particularly, retainer 224 is configured to make lid 222 only in the scope of a shown in Fig. 9 A, to rotate.Here a for example is 5mm.

At this, Fig. 9 A illustrates the cap unit 220 under the state that lid 222 is opened supply port 210a, and Fig. 9 B illustrates at lid 222 cap unit 220 under the supply port 210a closing state.That is, in the cap unit shown in Fig. 9 B 220, force application part 223 gives the application of force of closing direction (below being) in Fig. 9 B that lid 222 is closed supply port 210a.

Then, the on-off action to cap unit 220 describes particularly.

Figure 10 A and Figure 10 B are the figure that is used to explain the on-off action of cap unit 220.Particularly, Figure 10 A representes the state of opening of cap unit 220, and Figure 10 B representes the state that closes of cap unit 220.

At first, shown in Figure 10 A, the driving of the drive division 260 through control part 270 control, axis body 221 rotates (in Figure 10 A, turning right), and lid 222 is opened supply port 210a.Open force application part 223 and retainer 224 under the state at this, become the configuration of the state shown in Fig. 9 A with respect to lid 222.That is, be the state that force application part 223 does not give lid 222 application of forces.

Then, shown in Figure 10 B, the driving of the drive division 260 through control part 270 control, axis body 221 rotates (in Figure 10 B, turning left), and lid 222 is closed supply port 210a.This closes force application part 223 and retainer 224 under the state becomes the state shown in Fig. 9 B with respect to lid 222 configuration.That is, force application part 223 is to give the state that lid 222 is closed the application of force of closing direction of supply port 210a.

Particularly, at first, begin to rotate from the state shown in Figure 10 A through axis body 221, under the state shown in Fig. 9 A, lid 222 is closed supply port 210a.Then, further rotate through axis body 221, retainer 224 rotates around axis body 221, and force application part 223 and retainer 224 become the configuration of the state shown in Fig. 9 B.

Figure 11 A and Figure 11 B are the figure that closes action that is used to explain the cap unit 220 of the situation that accompanies ice.Particularly, Figure 11 A representes to accompany the state that closes of cap unit 220 of the situation of ice, and Figure 11 B representes to ice the state that closes of the cap unit 220 after the dissolving.

At first, shown in Figure 11 A, axis body 221 begins to rotate (among Figure 11 A, turning left) from the state shown in Figure 10 A.And under the state shown in Fig. 9 A that accompanies ice Q between lid 222 and the supply port 210a, lid 222 is closed supply port 210a.

Then, further rotate through axis body 221, retainer 224 rotates around axis body 221, and force application part 223 and retainer 224 become the configuration of the state shown in Fig. 9 B.That is, force application part 223 is to give the application of force of closing direction that lid 222 is closed supply port 210a.

At this, though between lid 222 and supply port 210a, accompany ice Q always, under this state, the driving of the drive division 260 of control part 270 controls is stopped.Therefore, the rotation of axis body 221 also is fixed on the position of the state that accompanies ice Q.

Then, shown in Figure 11 B, when the ice Q that accompanies dissolved, through force application part 223, lid 222 was closed supply port 210a.Particularly, because the application of force of closing direction to lid 222 that force application part 223 produces, along with the ice Q dissolving that accompanies, lid 222 rotates around axis body 221.And lid 222 becomes the configuration of the state shown in Fig. 9 A, thereby supply port 210a is closed fully with respect to force application part 223 and retainer 224.

As stated, under the state that drive division 260 stops, axis body 221 is fixed, give the application of force of closing direction that lid 222 is closed supply port 210a through force application part 223.Therefore, even ice tongs between supply port 210a and lid 222, dissolved if should ice, because the effect of the application of force of force application part 223, lid 222 also can be closed supply port 210a.In addition, at this moment, need not be used for the electric power that lid 222 is closed supply port 210a.

At this, because lid 222 rotating scopes are scopes of a shown in Fig. 9 A, so because of the varying in size of folded ice, the situation that exists lid 222 can not supply port 210a be closed fully.

Therefore, control part 270 control drive divisions 260 rotate axis body 221, make that lid 222 is closed supply port 210a with official hour at interval.Thus, lid 222 can be closed supply port 210a fully.

In addition, axis body 221 is rotated constantly, but control drive division 260 at interval axis body 221 is rotated, so can suppress extra power consumption with official hour because control part 270 is not a control drive division 260.

Therefore,, also can suppress extra power consumption, and can lid 222 be closed fully even between supply port 210a and lid 222, accompany under the situation of ice.

More than, use above-mentioned embodiment that refrigerator of the present invention is illustrated, but the present invention is not limited thereto.

That is, should think that this disclosed embodiment is example in all respects, and nonrestrictive content.Scope of the present invention is not above-mentioned explanation, and is represented by the scope of claim, is intended to comprise and the impartial meaning of the scope of claim and all changes in the scope.

For example in this embodiment, force application part 223 is a torque spring.But force application part 223 is not limited to torque spring.

Figure 12 is the figure of variation of this embodiment of expression force application part.

Shown in figure 12, cap unit 220 replaces force application part 223 shown in Figure 8 and has force application part 223a.And force application part 223a is tabular flat spring.And the end of force application part 223a is fixed in axis body 221, and the other end of force application part 223a is fixed in lid 222.Thus, force application part 223a can give the application of force of closing direction that lid 222 is closed supply port 210a.In addition, in this case, because shown in Fig. 9 A, the rotation of lid 222 does not receive retainer 224 restrictions, so even accompany bigger ice, lid 222 also can be closed supply port 210a fully.
